-- **IMPORTANT**: Before upgrading to a new version, **always check for [breaking changes](https://neovim.io/doc/user/news.html#news-breaking).**
-
-
-## Quick start
-
-1. Install [build prerequisites](#build-prerequisites) on your system
-2. `git clone https://github.com/neovim/neovim`
-3. `cd neovim && make CMAKE_BUILD_TYPE=RelWithDebInfo`
-    - If you want the **stable release**, also run `git checkout stable`.
-    - If you want to install to a custom location, set `CMAKE_INSTALL_PREFIX`. See also [INSTALL.md](./INSTALL.md#install-from-source).
-    - On BSD, use `gmake` instead of `make`.
-    - To build on Windows, see the [Building on Windows](#building-on-windows) section. _MSVC (Visual Studio) is recommended._
-4. `sudo make install`
-    - Default install location is `/usr/local`
-    - On Debian/Ubuntu, instead of installing files directly with `sudo make install`, you can run `cd build && cpack -G DEB && sudo dpkg -i nvim-linux64.deb` to build DEB-package and install it. This should help ensuring the clean removal of installed files.
-
-**Notes**:
-- From the repository's root directory, running `make` will download and build all the needed dependencies and put the `nvim` executable in `build/bin`.
-- Third-party dependencies (libuv, LuaJIT, etc.) are downloaded automatically to `.deps/`. See the [FAQ](https://neovim.io/doc/user/faq.html#faq-build) if you have issues.
-- After building, you can run the `nvim` executable without installing it by running `VIMRUNTIME=runtime ./build/bin/nvim`.
-- If you plan to develop Neovim, install [Ninja](https://ninja-build.org/) for faster builds. It will automatically be used.
-- Install [ccache](https://ccache.dev/) for faster rebuilds of Neovim. It's used by default. To disable it, use `CCACHE_DISABLE=true make`.
-
-## Running tests
-
-See [test/README.md](https://github.com/neovim/neovim/blob/master/test/README.md).
-
-## Building
-
-First make sure you installed the [build prerequisites](#build-prerequisites). Now that you have the dependencies, you can try other build targets explained below.
-
-The _build type_ determines the level of used compiler optimizations and debug information:
-
-- `Release`: Full compiler optimizations and no debug information. Expect the best performance from this build type. Often used by package maintainers.
-- `Debug`: Full debug information; few optimizations. Use this for development to get meaningful output from debuggers like GDB or LLDB. This is the default if `CMAKE_BUILD_TYPE` is not specified.
-- `RelWithDebInfo` ("Release With Debug Info"): Enables many optimizations and adds enough debug info so that when Neovim ever crashes, you can still get a backtrace.
-
-So, for a release build, just use:
-
-```
-make CMAKE_BUILD_TYPE=Release
-```
-(Do not add a `-j` flag if `ninja` is installed! The build will be in parallel automatically.)
-
-Afterwards, the `nvim` executable can be found in `build/bin`. To verify the build type after compilation, run:
-
-```sh
-./build/bin/nvim --version | grep ^Build
-```
-
-To install the executable to a certain location, use:
-
-```
-make CMAKE_INSTALL_PREFIX=$HOME/local/nvim install
-```
-
-CMake, our main build system, caches a lot of things in `build/CMakeCache.txt`. If you ever want to change `CMAKE_BUILD_TYPE` or `CMAKE_INSTALL_PREFIX`, run `rm -rf build` first. This is also required when rebuilding after a Git commit adds or removes files (including from `runtime`) — when in doubt, run `make distclean` (which is basically a shortcut for `rm -rf build .deps`).
-
-By default (`USE_BUNDLED=1`), Neovim downloads and statically links its needed dependencies. In order to be able to use a debugger on these libraries, you might want to compile them with debug information as well:
-
-<!-- THIS CAUSES SCREEN INTERFERENCE
-```
-make distclean
-VERBOSE=1 DEBUG=1 make deps
-```
--->
-```
-make distclean
-make deps
-```
-
-## Building on Windows
-
-### Windows / MSVC
-
-**MSVC (Visual Studio) is the recommended way to build on Windows.** These steps were confirmed as of 2023.
-
-1. Install [Visual Studio](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=Community) (2017 or later) with the _Desktop development with C++_ workload.
-    - On 32-bit Windows, you will need [this workaround](https://developercommunity.visualstudio.com/content/problem/212989/ninja-binary-format.html).
-2. Open the Neovim project folder.
-    - Visual Studio should detect the cmake files and automatically start building...
-3. Choose the `nvim.exe (bin\nvim.exe)` target and hit F5.
-    - If the build fails, it may be because Visual Studio started the build with `x64-{Debug,Release}` before you switched the configuration to `x86-Release`.
-      - Right-click _CMakeLists.txt → Delete Cache_.
-      - Right-click _CMakeLists.txt → Generate Cache_.
-    - If you see an "access violation" from `ntdll`, you can ignore it and continue.
-4. If you set an error like `msgpackc.dll not found`, try the `nvim.exe (Install)` target. Then switch back to `nvim.exe (bin\nvim.exe)`.
-
-### Windows / MSVC PowerShell
-
-To build from the command line (i.e. invoke the `cmake` commands yourself),
-
-1. Ensure you have the Visual Studio environment variables, using any of the following:
-    - Using the [Visual Studio Developer Command Prompt or Visual Studio Developer PowerShell](https://learn.microsoft.com/en-us/visualstudio/ide/reference/command-prompt-powershell?view=vs-2022)
-    - Invoking `Import-VisualStudioVars` in PowerShell from [this PowerShell module](https://github.com/Pscx/Pscx)
-    - Invoking `VsDevCmd.bat` in Command Prompt
-      ```
-      VsDevCmd.bat -arch=x64
-      ```
-   This is to make sure that `luarocks` finds the Visual Studio installation, and doesn't fall back to MinGW with errors like:
-   ```
-   'mingw32-gcc' is not recognized as an internal or external command
-   ```
-2. From the "Developer PowerShell" or "Developer Command Prompt":
-   ```
-   cmake -S cmake.deps -B .deps -G Ninja -D CMAKE_BUILD_TYPE=Release
-   cmake --build .deps --config Release
-   cmake -B build -G Ninja -D CMAKE_BUILD_TYPE=Release
-   cmake --build build --config Release
-   ```
-    - Omit `--config Release` if you want a debug build.
-    - Omit `-G Ninja` to use the "Visual Studio" generator.
-
-### Windows / CLion
-
-1. Install [CLion](https://www.jetbrains.com/clion/).
-2. Open the Neovim project in CLion.
-3. Select _Build → Build All in 'Release'_.
-
-### Windows / Cygwin
-
-Install all dependencies the normal way, then build Neovim the normal way for a random CMake application (i.e. do not use the `Makefile` that automatically downloads and builds "bundled" dependencies).
-
-The `cygport` repo contains Cygport files (e.g. `APKBUILD`, `PKGBUILD`) for all the dependencies not available in the Cygwin distribution, and describes any special commands or arguments needed to build. The Cygport definitions also try to describe the required dependencies for each one. Unless custom commands are provided, Cygport just calls `autogen`/`cmake`, `make`, `make install`, etc. in a clean and consistent way.
-
-https://github.com/cascent/neovim-cygwin was built on Cygwin 2.9.0. Newer `libuv` should require slightly less patching. Some SSP stuff changed in Cygwin 2.10.0, so that might change things too when building Neovim.
-
-
-### Windows / MSYS2 / MinGW
-
-1. From the MSYS2 shell, install these packages:
-   ```
-   pacman -S \
-       mingw-w64-x86_64-{gcc,cmake,make,ninja,diffutils}
-   ```
-2. From the Windows Command Prompt (`cmd.exe`), set up the `PATH` and build.
-
-   ```cmd
-   set PATH=c:\msys64\mingw64\bin;c:\msys64\usr\bin;%PATH%
-   ```
-3. You have two options:
-    - Build using `cmake` and `Ninja` generator:
-      ```cmd
-      cmake -S cmake.deps -B .deps -G Ninja -D CMAKE_BUILD_TYPE=RelWithDebInfo
-      cmake --build .deps
-      cmake -B build -G Ninja -D CMAKE_BUILD_TYPE=RelWithDebInfo
-      cmake --build build
-      ```
-      If you cannot install neovim with `ninja install` due to permission restriction, you can install neovim in a directory you have write access to.
-      ```cmd
-      cmake -S cmake.deps -B .deps -G Ninja -D CMAKE_BUILD_TYPE=RelWithDebInfo
-      cmake --build .deps
-      cmake -B build -G Ninja -D CMAKE_INSTALL_PREFIX=C:\nvim -D CMAKE_BUILD_TYPE=RelWithDebInfo
-      cmake --build build
-      ```
-    - Or, alternatively, you can use `mingw32-make`:
-      ```cmd
-      mingw32-make deps
-      mingw32-make CMAKE_BUILD_TYPE=RelWithDebInfo
-      :: Or you can do the previous command specifying a custom prefix
-      :: (Default is C:\Program Files (x86)\nvim)
-      :: mingw32-make CMAKE_BUILD_TYPE=RelWithDebInfo CMAKE_INSTALL_PREFIX=C:\nvim
-      mingw32-make install
-      ```
-
-## Localization
-
-### Localization build
-
-A normal build will create `.mo` files in `build/src/nvim/po`.
-
-* If you see `msgfmt: command not found`, you need to install [`gettext`](http://en.wikipedia.org/wiki/Gettext). On most systems, the package is just called `gettext`.
-
-### Localization check
-
-To check the translations for `$LANG`, run `make -C build check-po-$LANG`. Examples:
-
-```
-cmake --build build --target check-po-de
-cmake --build build --target check-po-pt_BR
-```
-
-- `check-po-$LANG` generates a detailed report in `./build/src/nvim/po/check-${LANG}.log`. (The report is generated by `nvim`, not by `msgfmt`.)
-
-### Localization update
-
-To update the `src/nvim/po/$LANG.po` file with the latest strings, run the following:
-
-```
-cmake --build build --target update-po-$LANG
-```
-
-- **Note**: Run `src/nvim/po/cleanup.vim` after updating.
-
-## Compiler options
-
-To see the chain of includes, use the `-H` option ([#918](https://github.com/neovim/neovim/issues/918)):
-
-```sh
-echo '#include "./src/nvim/buffer.h"' | \
-> clang -I.deps/usr/include -Isrc -std=c99 -P -E -H - 2>&1 >/dev/null | \
-> grep -v /usr/
-```
-
-- `grep -v /usr/` is used to filter out system header files.
-- `-save-temps` can be added as well to see expanded macros or commented assembly.
-
-## Custom Makefile
-
-You can customize the build process locally by creating a `local.mk`, which is referenced at the top of the main `Makefile`. It's listed in `.gitignore`, so it can be used across branches. **A new target in `local.mk` overrides the default make-target.**
-
-Here's a sample `local.mk` which adds a target to force a rebuild but *does not* override the default-target:
-
-```make
-all:
-
-rebuild:
-	rm -rf build
-	make
-```
-
-## Third-party dependencies
-
-Reference the [Debian package](https://packages.debian.org/sid/source/neovim) (or alternatively, the [Homebrew formula](https://github.com/Homebrew/homebrew-core/blob/master/Formula/neovim.rb)) for the precise list of dependencies/versions.
-
-To build the bundled dependencies using CMake:
-
-```sh
-cmake -S cmake.deps -B .deps -G Ninja -D CMAKE_BUILD_TYPE=RelWithDebInfo
-cmake --build .deps
-```
-
-By default the libraries and headers are placed in `.deps/usr`. Now you can build Neovim:
-
-```sh
-cmake -B build -G Ninja -D CMAKE_BUILD_TYPE=RelWithDebInfo
-cmake --build build
-```
-
-### How to build without "bundled" dependencies
-
-1. Manually install the dependencies:
-    - libuv libluv libvterm luajit lua-lpeg lua-mpack msgpack-c tree-sitter tree-sitter-c tree-sitter-lua tree-sitter-markdown tree-sitter-query tree-sitter-vim tree-sitter-vimdoc unibilium
-2. Run CMake:
-   ```sh
-   cmake -B build -G Ninja -D CMAKE_BUILD_TYPE=RelWithDebInfo
-   cmake --build build
-   ```
-   If all the dependencies are not available in the package, you can use only some of the bundled dependencies as follows (example of using `ninja`):
-   ```sh
-   cmake -S cmake.deps -B .deps -G Ninja -D CMAKE_BUILD_TYPE=RelWithDebInfo -DUSE_BUNDLED=OFF -DUSE_BUNDLED_LIBVTERM=ON -DUSE_BUNDLED_TS=ON
-   cmake --build .deps
-   cmake -B build -G Ninja -D CMAKE_BUILD_TYPE=RelWithDebInfo
-   cmake --build build
-   ```
-3. Run `make`, `ninja`, or whatever build tool you told CMake to generate.
-    - Using `ninja` is strongly recommended.
-4. If treesitter parsers are not bundled, they need to be available in a `parser/` runtime directory (e.g. `/usr/share/nvim/runtime/parser/`).
-
-#### Debian 10 (Buster) example:
-
-```sh
-sudo apt install luajit libluajit-5.1-dev lua-mpack lua-lpeg libunibilium-dev libmsgpack-dev
-cmake -S cmake.deps -B .deps -G Ninja -D CMAKE_BUILD_TYPE=RelWithDebInfo -DUSE_BUNDLED=OFF -DUSE_BUNDLED_LIBUV=ON -DUSE_BUNDLED_LUV=ON -DUSE_BUNDLED_LIBVTERM=ON -DUSE_BUNDLED_TS=ON
-cmake --build .deps
-cmake -B build -G Ninja -D CMAKE_BUILD_TYPE=RelWithDebInfo
-cmake --build build
-```
-
-#### Example of using a Makefile
-
-- Example of using a package with all dependencies:
-  ```
-  make USE_BUNDLED=OFF
-  ```
-- Example of using a package with some dependencies:
-  ```
-  make BUNDLED_CMAKE_FLAG="-DUSE_BUNDLED=OFF -DUSE_BUNDLED_LUV=ON -DUSE_BUNDLED_TS=ON -DUSE_BUNDLED_LIBVTERM=ON -DUSE_BUNDLED_LIBUV=ON"
-  ```
-
-## Build prerequisites
-
-General requirements (see [#1469](https://github.com/neovim/neovim/issues/1469#issuecomment-63058312)):
-
-- Clang or GCC version 4.9+
-- CMake version 3.13+, built with TLS/SSL support
-  - Optional: Get the latest CMake from an [installer](https://github.com/Kitware/CMake/releases) or the [Python package](https://pypi.org/project/cmake/) (`pip install cmake`)
-
-Platform-specific requirements are listed below.
-
-### Ubuntu / Debian
-
-```sh
-sudo apt-get install ninja-build gettext cmake unzip curl build-essential
-```
-
-### RHEL / Fedora
-
-```
-sudo dnf -y install ninja-build cmake gcc make unzip gettext curl glibc-gconv-extra
-```
-
-### openSUSE
-
-```
-sudo zypper install ninja cmake gcc-c++ gettext-tools curl
-```
-
-### Arch Linux
-
-```
-sudo pacman -S base-devel cmake unzip ninja curl
-```
-
-### Alpine Linux
-
-```
-apk add build-base cmake coreutils curl unzip gettext-tiny-dev
-```
-
-### Void Linux
-
-```
-xbps-install base-devel cmake curl git
-```
-
-### NixOS / Nix
-
-Starting from NixOS 18.03, the Neovim binary resides in the `neovim-unwrapped` Nix package (the `neovim` package being just a wrapper to setup runtime options like Ruby/Python support):
-
-```sh
-cd path/to/neovim/src
-```
-
-Drop into `nix-shell` to pull in the Neovim dependencies:
-
-```
-nix-shell '<nixpkgs>' -A neovim-unwrapped
-```
-
-Configure and build:
-
-```sh
-rm -rf build && cmakeConfigurePhase
-buildPhase
-```
-
-Tests are not available by default, because of some unfixed failures. You can enable them via adding this package in your overlay:
-```
-  neovim-dev = (super.pkgs.neovim-unwrapped.override  {
-    doCheck=true;
-  }).overrideAttrs(oa:{
-    cmakeBuildType="debug";
-
-    nativeBuildInputs = oa.nativeBuildInputs ++ [ self.pkgs.valgrind ];
-    shellHook = ''
-      export NVIM_PYTHON_LOG_LEVEL=DEBUG
-      export NVIM_LOG_FILE=/tmp/log
-      export VALGRIND_LOG="$PWD/valgrind.log"
-    '';
-  });
-```
-and replacing `neovim-unwrapped` with `neovim-dev`:
-```
-nix-shell '<nixpkgs>' -A neovim-dev
-```
-
-Neovim contains a Nix flake in the `contrib` folder, with 3 packages:
-- `neovim` to run the nightly
-- `neovim-debug` to run the package with debug symbols
-- `neovim-developer` to get all the tools to develop on `neovim`
-
-Thus you can run Neovim nightly with `nix run github:neovim/neovim?dir=contrib`.
-Similarly to develop on Neovim: `nix develop github:neovim/neovim?dir=contrib#neovim-developer`.
-
-### FreeBSD
-
-```
-sudo pkg install cmake gmake sha unzip wget gettext curl
-```
-
-If you get an error regarding a `sha256sum` mismatch, where the actual SHA-256 hash is `e3b0c44298fc1c149afbf4c8996fb92427ae41e4649b934ca495991b7852b855`, then this is your issue (that's the `sha256sum` of an empty file).
-
-### OpenBSD
-
-```sh
-doas pkg_add gmake cmake unzip curl gettext-tools
-```
-
-Build can sometimes fail when using the top level `Makefile`, apparently due to some third-party component (see [#2445-comment](https://github.com/neovim/neovim/issues/2445#issuecomment-108124236)). The following instructions use CMake:
-
-```sh
-mkdir .deps
-cd .deps
-cmake ../cmake.deps/
-gmake
-cd ..
-mkdir build
-cd build
-cmake ..
-gmake
-```
-
-### macOS
-
-#### macOS / Homebrew
-
-1. Install Xcode Command Line Tools: `xcode-select --install`
-2. Install [Homebrew](http://brew.sh)
-3. Install Neovim build dependencies:
-    ```
-    brew install ninja cmake gettext curl
-    ```
-  - **Note**: If you see Wget certificate errors (for older macOS versions less than 10.10):
-    ```sh
-    brew install curl-ca-bundle
-    echo CA_CERTIFICATE=$(brew --prefix curl-ca-bundle)/share/ca-bundle.crt >> ~/.wgetrc
-    ```
-  - **Note**: If you see `'stdio.h' file not found`, try the following:
-    ```
-    open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
-    ```
-
-#### macOS / MacPorts
-
-1. Install Xcode Command Line Tools: `xcode-select --install`
-2. Install [MacPorts](http://www.macports.org)
-3. Install Neovim build dependencies:
-    ```
-    sudo port install ninja cmake gettext
-    ```
-  - **Note**: If you see Wget certificate errors (for older macOS versions less than 10.10):
-    ```sh
-    sudo port install curl-ca-bundle
-    echo CA_CERTIFICATE=/opt/local/share/curl/curl-ca-bundle.crt >> ~/.wgetrc
-    ```
-  - **Note**: If you see `'stdio.h' file not found`, try the following:
-    ```
-    open /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg
-    ```
-
-#### Building for older macOS versions
-
-From a newer macOS version, to build for older macOS versions, you will have to set the macOS deployment target:
-
-```
-make CMAKE_BUILD_TYPE=Release MACOSX_DEPLOYMENT_TARGET=10.13 DEPS_CMAKE_FLAGS="-DCMAKE_CXX_COMPILER=$(xcrun -find c++)"
-```
-
-Note that the C++ compiler is explicitly set so that it can be found when the deployment target is set.

-- There's also a make target that automatically fixes the suggestions from
-  IWYU:
-  ```bash
-  make iwyu
-  ```
-
-See [#549][549] for more details.
-
-### Lua runtime files
-
-Most of the Lua core [`runtime/`](./runtime) modules are precompiled to
-bytecode, so changes to those files won't get used unless you rebuild Nvim or
-by passing `--luamod-dev` and `$VIMRUNTIME`. For example, try adding a function
-to `runtime/lua/vim/_editor.lua` then:
-
-```bash
-VIMRUNTIME=./runtime ./build/bin/nvim --luamod-dev
-```
-
-Documentation
--------------
-
-Read [:help dev-doc][dev-doc-guide] to understand the expected documentation style and conventions.
-
-### Generating :help
-
-Many `:help` docs are autogenerated from (C or Lua) docstrings. To generate the documentation run:
-
-```bash
-make doc
-```
-
-To validate the documentation files, run:
-
-```bash
-make lintdoc
-```
-
-If you need to modify or debug the documentation flow, these are the main files:
-- `./scripts/gen_vimdoc.lua`:
-  Main doc generator. Parses C and Lua files to render vimdoc files.
-- `./scripts/luacats_parser.lua`:
-  Documentation parser for Lua files.
-- `./scripts/cdoc_parser.lua`:
-  Documentation parser for C files.
-- `./scripts/luacats_grammar.lua`:
-  Lpeg grammar for LuaCATS
-- `./scripts/cdoc_grammar.lua`:
-  Lpeg grammar for C doc comments
-- `./scripts/gen_eval_files.lua`:
-  Generates documentation and Lua type files from metadata files:
-  ```
-  runtime/lua/vim/*     =>  runtime/doc/lua.txt
-  runtime/lua/vim/*     =>  runtime/doc/lua.txt
-  runtime/lua/vim/lsp/  =>  runtime/doc/lsp.txt
-  src/nvim/api/*        =>  runtime/doc/api.txt
-  src/nvim/eval.lua     =>  runtime/doc/builtin.txt
-  src/nvim/options.lua  =>  runtime/doc/options.txt
-  ```
-
-- `./scripts/lintdoc.lua`: Validation and linting of documentation files.
-
-### Lua docstrings
-
-Use [LuaLS] annotations in Lua docstrings to annotate parameter types, return
-types, etc. See [:help dev-lua-doc][dev-lua-doc].
-
-- The template for function documentation is:
-  ```lua
-  --- {Brief}
-  ---
-  --- {Long explanation}
-  ---
-  --- @param arg1 type {description}
-  --- @param arg2 type {description}
-  --- ...
-  ---
-  --- @return type {description}
-  ```
-- If possible, add type information (`table`, `string`, `number`, ...). Multiple valid types are separated by a bar (`string|table`). Indicate optional parameters via `type|nil`.
-- If a function in your Lua module should _not_ be documented, add `@nodoc`.
-- If the function is internal or otherwise non-public add `@private`.
-      - Private functions usually should be underscore-prefixed (named "_foo", not "foo").
-- Mark deprecated functions with `@deprecated`.
-
-Third-party dependencies
-------------------------
-
-To build Nvim using a different commit of a dependency change the appropriate
-URL in `cmake.deps/deps.txt`. For example, to use a different version of luajit
-replace the value in `LUAJIT_URL` with the wanted commit hash:
-
-```bash
-LUAJIT_URL https://github.com/LuaJIT/LuaJIT/archive/<sha>.tar.gz
-```
-
-Set `DEPS_IGNORE_SHA` to `TRUE` in `cmake.deps/CMakeLists.txt` to skip hash
-check from cmake.
-
-Alternatively, you may point the URL as a local path where the repository is.
-This is convenient when bisecting a problem in a dependency with `git bisect`.
-This may require running `make distclean` between each build. Hash checking is
-always skipped in this case regardless of `DEPS_IGNORE_SHA`.
-
-```bash
-LUAJIT_URL /home/user/luajit
-```
 
 Reviewing
 ---------
 
+To help review pull requests, start with [this checklist][review-checklist].
+
 Reviewing can be done on GitHub, but you may find it easier to do locally.
-Using [GitHub CLI][gh], you can create a new branch with the contents of a pull
+Using [`hub`][hub], you can create a new branch with the contents of a pull
 request, e.g. [#1820][1820]:
 
-```bash
-gh pr checkout https://github.com/neovim/neovim/pull/1820
-```
+    hub checkout https://github.com/neovim/neovim/pull/1820
 
 Use [`git log -p master..FETCH_HEAD`][git-history-filtering] to list all
 commits in the feature branch which aren't in the `master` branch; `-p`
 shows each commit's diff. To show the whole surrounding function of a change
 as context, use the `-W` argument as well.

-
-Install from package
-====================
-
-Packages are listed below. (You can also [build Neovim from source](#install-from-source).)
-
-## Windows
-
-Windows 8+ is required. Windows 7 or older is not supported.
-
-### [Winget](https://docs.microsoft.com/en-us/windows/package-manager/winget/)
-
-- **Release:** `winget install Neovim.Neovim`
-
-### [Chocolatey](https://chocolatey.org)
-
-- **Latest Release:** `choco install neovim` (use -y for automatically skipping confirmation messages)
-- **Development (pre-release):** `choco install neovim --pre`
-
-### [Scoop](https://scoop.sh/)
-```
-scoop bucket add main
-scoop install neovim
-```
-- **Release:** `scoop install neovim`
-
-Several Neovim GUIs are available from scoop (extras): [scoop.sh/#/apps?q=neovim](https://scoop.sh/#/apps?q=neovim)
-
-### Pre-built archives
-
-0. If you are missing `VCRUNTIME140.dll`, install the [Visual Studio 2015 C++ redistributable](https://support.microsoft.com/en-us/kb/2977003) (choose x86_64 or x86 depending on your system).
-1. Choose a package (**nvim-winXX.zip**) from the [releases page](https://github.com/neovim/neovim/releases).
-2. Unzip the package. Any location is fine, administrator privileges are _not_ required.
-    - `$VIMRUNTIME` will be set to that location automatically.
-3. Run `nvim.exe` from a terminal.
-
-**Optional** steps:
-
-- Add the `bin` folder (e.g. `C:\Program Files\nvim\bin`) to your PATH.
-    - This makes it easy to run `nvim` from anywhere.
-- If `:set spell` does not work, create the `C:/Users/foo/AppData/Local/nvim/site/spell` folder.
-  You can then copy your spell files over (for English, located
-  [here](https://github.com/vim/vim/blob/master/runtime/spell/en.utf-8.spl) and
-  [here](https://github.com/vim/vim/blob/master/runtime/spell/en.utf-8.sug));
-- For Python plugins you need the `pynvim` module. "Virtual envs" are recommended. After activating the virtual env do `pip install pynvim` (in *both*). Edit your `init.vim` so that it contains the path to the env's Python executable:
-    ```vim
-    let g:python3_host_prog='C:/Users/foo/Envs/neovim3/Scripts/python.exe'
-    ```
-    - Run `:checkhealth` and read `:help provider-python`.
-- **init.vim ("vimrc"):** If you already have Vim installed you can copy `%userprofile%\_vimrc` to `%userprofile%\AppData\Local\nvim\init.vim` to use your Vim config with Neovim.
-

-## Linux
-
-### Pre-built archives
-
-The [Releases](https://github.com/neovim/neovim/releases) page provides pre-built binaries for Linux systems.
-
-```sh
-curl -LO https://github.com/neovim/neovim/releases/latest/download/nvim-linux64.tar.gz

-
-After this step add this to `~/.bashrc`:
-
-    export PATH="$PATH:/opt/nvim-linux64/bin"
-
-### AppImage ("universal" Linux package)
-
-The [Releases](https://github.com/neovim/neovim/releases) page provides an [AppImage](https://appimage.org) that runs on most Linux systems. No installation is needed, just download `nvim.appimage` and run it. (It might not work if your Linux distribution is more than 4 years old.)
-
-    curl -LO https://github.com/neovim/neovim/releases/latest/download/nvim.appimage
-    chmod u+x nvim.appimage
-    ./nvim.appimage
-
-To expose nvim globally:
-
-    mkdir -p /opt/nvim
-    mv nvim.appimage /opt/nvim/nvim
-
-And the following line to `~/.bashrc`:
-
-    export PATH="$PATH:/opt/nvim/"
-
-If the `./nvim.appimage` command fails, try:
-```sh
-./nvim.appimage --appimage-extract
-./squashfs-root/AppRun --version

-If a package is not provided for your platform, you can build Neovim from source. See [BUILD.md](./BUILD.md) for details.  If you have the [prerequisites](./BUILD.md#build-prerequisites) then building is easy:
-
-    make CMAKE_BUILD_TYPE=Release
-    sudo make install
-
-For Unix-like systems this installs Neovim to `/usr/local`, while for Windows to `C:\Program Files`. Note, however, that this can complicate uninstallation. The following example avoids this by isolating an installation under `$HOME/neovim`:
-
-    rm -r build/  # clear the CMake cache
-    make CMAKE_EXTRA_FLAGS="-DCMAKE_INSTALL_PREFIX=$HOME/neovim"
-    make install
-    export PATH="$HOME/neovim/bin:$PATH"
-
-## Uninstall
-
-There is a CMake target to _uninstall_ after `make install`:
-
-```sh
-sudo cmake --build build/ --target uninstall
-```
-
-Alternatively, just delete the `CMAKE_INSTALL_PREFIX` artifacts:
-
-```sh
-sudo rm /usr/local/bin/nvim
-sudo rm -r /usr/local/share/nvim/
-```

-
-Deprecating and removing features
----------------------------------
-
-Neovim inherits many features and design decisions from Vim, not all of which
-align with the goals of this project. It is sometimes desired or necessary to
-remove existing features, or refactor parts of the code that would change
-user's workflow. In these cases, a deprecation policy is needed to properly
-inform users of the change.
-
-When a (non-experimental) feature is slated to be removed it should:
-
-1. Be _soft_ deprecated in the _next_ release
-    - Use of the deprecated feature will still work.
-    - This means deprecating via documentation and annotation (`@deprecated`).
-    - Include a note in `deprecated.txt`.
-    - For Lua features, use `vim.deprecate()`. The specified version is the
-      current minor version + 2. For example, if the current version is
-      `v0.10.0-dev-1957+gd676746c33` then use `0.12`.
-    - For Vimscript features, use `v:lua.vim.deprecate()`. Use the same version
-      as described for Lua features.
-2. Be _hard_ deprecated in a following a release in which it was soft deprecated.
-    - Use of the deprecated feature will still work but should issue a warning.
-    - Features implemented in C will need bespoke implementations to communicate
-      to users that the feature is deprecated.
-3. Be removed in a release following the release in which it was hard deprecated
-    - Usually this will be the next release, but it may be a later release if
-      a longer deprecation cycle is desired
-    - If possible, keep the feature as a stub (e.g. function API) and issue an
-      error when it is accessed.
-
-Example:
-
-                    Deprecation                            Removal
-                         ┆                 ┆                 ┆
-                         ┆      Soft       ┆      Hard       ┆
-                         ┆   Deprecation   ┆   Deprecation   ┆
-                         ┆     Period      ┆     Period      ┆
-             ────────────────────────────────────────────────────────────
-    Version:            0.10              0.11              0.12

-                              New code          New code         New code
-
-Feature removals which may benefit from community input or further discussion
-should also have a tracking issue (which should be linked to in the release
-notes).
-
-Exceptions to this policy may be made (for experimental subsystems or when
-there is broad consensus among maintainers). The rationale for the exception
-should be stated explicitly and publicly.
+The neovim repository includes a backport [github action](https://github.com/zeebe-io/backport-action).
+In order to trigger the action, a PR must be labeled with a label matching the
+form `backport release-0.X`. If the label is applied before the PR is merged,
+the backport will be filed automatically against the target branch. Otherwise,
+comment `\backport` on the merged PR *after* the label has been applied to trigger
+a backport. Note, the PR must have a description in the issue body, or the backport
+will fail.
 
 Third-party dependencies
-------------------------
+--------------
 
-For some dependencies we maintain temporary "forks", which are simply private
-branches with a few extra patches, while we wait for the upstream project to
-merge the patches. This is done instead of maintaining the patches as (fragile)
-CMake `PATCH_COMMAND` steps.
+These "bundled" dependencies can be updated by bumping their versions in `third-party/CMakeLists.txt`:

-Refactoring
------------
-
-### Frozen legacy modules
-
-Refactoring Vim structurally and aesthetically is an important goal of Neovim.
-But there are some modules that should not be changed significantly, because
-they are maintained Vim, at present. Until someone takes "ownership" of these
-modules, the cost of any significant changes (including style or structural
-changes that re-arrange the code) to these modules outweighs the benefit. The
-modules are:
-
-- `regexp.c`
-- `indent_c.c`
-
-Automation (CI)
----------------
-
-### Backup
-
-Discussions from issues and PRs are backed up here:
-https://github.com/neovim/neovim-backup
-
-### Development guidelines
-
-* CI and automation jobs are primarily driven by GitHub Actions.
-* Avoid macOS if an Ubuntu or a Windows runner can be used instead. This is
-  because macOS runners have [tighter restrictions on the number of concurrent
-  jobs](https://docs.github.com/en/actions/learn-github-actions/usage-limits-billing-and-administration#usage-limits).
-* Runner versions:
-    * For special-purpose jobs where the runner version doesn't really matter,
-      prefer `-latest` tags so we don't need to manually bump the versions. An
-      example of a special-purpose workflow is `labeler_pr.yml`.
-    * For our testing job `test.yml`, prefer to use the latest stable (i.e.
-      non-beta) version explicitly. Avoid using the `-latest` tags here as it
-      makes it difficult to determine from an unrelated PR if a failure is due
-      to the PR itself or due to GitHub bumping the `-latest` tag without our
-      knowledge. There's also a high risk that automatically bumping the CI
-      versions will fail due to manual work being required from experience.
-    * For our release job, which is `release.yml`, prefer to use the oldest
-      stable (i.e. non-deprecated) versions available. The reason is that we're
-      trying to produce images that work in the broadest number of environments,
-      and therefore want to use older releases.
-
-### Special labels
-
-Some github labels are used to trigger certain jobs:
-
-* `ci:backport release-x.y` - backport to branch `release-x.y`
-* `ci:s390x` - enable s390x CI
-* `ci:skip-news` - skip news.yml workflows
-* `ci:windows-asan` - test windows with ASAN enabled
-* `needs:response` - close PR after a certain amount of time if author doesn't
-  respond
+We also maintain some forks, particularly for Windows, if we are waiting on upstream changes:
+https://github.com/neovim/neovim/wiki/Deps
