+## Using alongside `nvim-treesitter`
+
+If `nvim-treesitter` is installed and has a justfile language parser available,
+`nvim-treesitter` will overrule `vim-just` by default.
+
+To use `vim-just` syntax highlighting with other `nvim-treesitter` features,
+configure `nvim-treesitter` not to use its justfile language parser for syntax highlighting:
+
+```lua
+require("nvim-treesitter.configs").setup({
+  highlight = {
+    enable = true,
+    disable = { "just" },
+  },
+})
+```
+
+For more details or more complex configurations, see
+[nvim-treesitter documentation](https://github.com/nvim-treesitter/nvim-treesitter#modules).
