+# VSCode extension for Grain
+
+The VSCode extension for the [Grain programming language](https://github.com/grain-lang/grain).
+
+**Requires:** vscode 1.67+
+
+## Functionality
+
+This LSP Protocol client provides the the following language features for grain (`.gr`) files:
+
+- Show compilation warnings and errors
+- Code lenses
+- Hover support
+
+## Running the extension
+
+- Run `npm ci` in this folder.
+- Open VSCode inside this folder.
+- Switch to the "Run and Debug" pane.
+- Select "Launch Extension" from the drop down.
+- Press the ▶️ button next to "Launch Extension", which will start a TypeScript watcher and launch a new VSCode instance titled `[Extension Development Host]`.
+- The Grain CLI needs to be on your path. If not, set the `cliPath` setting inside the `[Extension Development Host]` instance to the location of your Grain CLI.
+- In the `[Extension Development Host]` instance of VSCode, open a document in 'grain' language mode.
+- After a code change, you'll likely need to trigger a "Developer: Reload Window" action in the `[Extension Development Host]` instance before the extension will pick up the changes.
+
+## Useful files
+
+- `package.json` - this is the manifest file in which you declare your language support and define
+  the location of the grammar file that has been copied into your extension.
+- `syntaxes/grain.tmLanguage.json` - this is the Text mate grammar file that is used for tokenization.
+- `language-configuration.json` - this the language configuration, defining the tokens that are used for
+  comments and brackets.
