 ## Installation
 
 You can install `nvim-treesitter` with your favorite package manager (or using the native `package` feature of vim, see `:h packages`).
 
 **NOTE: This plugin is only guaranteed to work with specific versions of language parsers** (as specified in the `lockfile.json`). **When upgrading the plugin, you must make sure that all installed parsers are updated to the latest version** via `:TSUpdate`.
-It is strongly recommended to automate this; e.g., if you are using [vim-plug](https://github.com/junegunn/vim-plug), put this in your `init.vim` file:
+It is strongly recommended to automate this; e.g., if you are using `lazy.nvim`, put this in your `init.lua` file:
 
-```vim
-Plug 'nvim-treesitter/nvim-treesitter', {'do': ':TSUpdate'}
+```lua
+require("lazy").setup({
+  {"nvim-treesitter/nvim-treesitter", branch = 'master', lazy = false, build = ":TSUpdate"}
+})
 ```
 
+>[!CAUTION]
+> * This plugin does not support lazy-loading.
+> * Make sure to specify the `master` branch, as the default branch will switch to `main` in the future.
