-
-            ## Install
-
-            ### Windows
-
-            1. Extract **nvim-win64.zip** (or **nvim-win32.zip**)
-            2. Run `nvim-qt.exe`
-
-            ### macOS
-
-            1. Download **nvim-macos.tar.gz**
-            2. Extract: `tar xzvf nvim-macos.tar.gz`
-            3. Run `./nvim-osx64/bin/nvim`
-
-            ### Linux (x64)
-
-            1. Download **nvim.appimage**
-            2. Run `chmod u+x nvim.appimage && ./nvim.appimage`
-               - If your system does not have FUSE you can [extract the appimage](https://github.com/AppImage/AppImageKit/wiki/FUSE#type-2-appimage):
-                 ```
-                 ./nvim.appimage --appimage-extract
-                 ./squashfs-root/usr/bin/nvim
-                 ```
-
-            ### Other
-
-            - Install by [package manager](https://github.com/neovim/neovim/wiki/Installing-Neovim)

-  ASAN/UBSAN can be used to detect memory errors and other common forms of undefined behavior at runtime in debug builds.
-  To build neovim with sanitizers enabled, use
-  ```
-  rm -rf build && CMAKE_EXTRA_FLAGS="-DCMAKE_C_COMPILER=clang -DCLANG_ASAN_UBSAN=1" make
-  ```
-  When running neovim, use
-  ```
-  UBSAN_OPTIONS=print_stacktrace=1 ASAN_OPTIONS=log_path=/tmp/nvim_asan nvim args...
-  ```
-  If neovim exits unexpectedly, check `/tmp/nvim_asan.{PID}` (or your preferred `log_path`) for log files with error messages.
