+### Tree-Sitter parser
+
+We are using a Tree-Sitter parser for our HTTP files, in order to get the correct syntax highlighting
+you should add this before your tree-sitter setup.
+
+```lua
+local parser_configs = require("nvim-treesitter.parsers").get_parser_configs()
+parser_configs.http = {
+  install_info = {
+    url = "https://github.com/NTBBloodbath/tree-sitter-http",
+    files = { "src/parser.c" },
+    branch = "main",
+  },
+}
+```
+
+And then add `"http"` in your `ensure_installed` table or manually run `:TSInstall http`.
