+# gdLint Plugin
+
+A bare-bones plugin to run gdLint in Godot 4.x.
+
+## Setup
+
+Install [gdscript-toolkit](https://github.com/Scony/godot-gdscript-toolkit).
+
+If you install the toolkit in a venv, you may want to edit
+`run_linter.gd` to set the path to the `gdlint` binary
+(e.g. `venv/bin/gdlint`). That way, you won't have to run Godot
+through a venv just to use `gdlint`.
+
+## About
+
+This is an extremely simple implementation -- the plugin runs `gdlint`
+on save, and raises any errors as warnings.
+
+If you want more full-featured linter integration, check out
+[el-falso/gdlinter](https://github.com/el-falso/gdlinter). When I
+wrote this plugin, it wasn't being actively maintained.
