 **nvim-treesitter-main** is a flake that builds the new `main` branch `nvim-treesitter`, along with all of the parser versions from the [`parsers.lua`](https://github.com/nvim-treesitter/nvim-treesitter/blob/main/lua/nvim-treesitter/parsers.lua) file, as recommended by the project.
 
+## Deprecation
+The `nvim-treesitter` main branch was merged into [nixpkgs](https://github.com/NixOS/nixpkgs/pull/470883) in late 2025.
