+
+  `:GoJson` opens a temporary buffer where you can paste or write JSON.
+  Saving the buffer (`:w` or `:wq`) automatically closes it and inserts the generated Go struct into the original buffer at the cursor position.
+
+  Alternatively, you can pass JSON directly as an argument:
+  ```vim
+  :GoJson {"name": "Alice", "age": 30}
+  ```
+
+  Additionally, `gopher.json2go` provides lua api, see `:h gopher.nvim-json2go` for details.
