+
+#### `> ReScript: Create an interface file for this implementation file.`
+
+Creates an interface file (`.resi`) for the current `.res` file, automatically filling in all types and values in the current file.
+
+#### `> Open the compiled JS file for this implementation file.`
+
+Opens the compiled JS file for the current ReScript file.
+
+#### `> ReScript: Switch implementation/interface`
+
+Switches between the implementation and interface file. If you're in a `.res` file, the command will open the corresponding `.resi` file (if it exists), and if you're in a `.resi` file the command will open the corresponding `.res` file.

+## Configuration
+
+### Hide generated files
+
+You can configure VSCode to collapse the JavaScript files ReScript generates under its source ReScript file. This will "hide" the generated files in the VSCode file explorer, but still leaving them accessible by expanding the source ReScript file they belong to.
+
+Open your VSCode settings and type `editor.filenesting`. Enable the feature and scroll down to patterns.

+
+This nests implementations under interfaces if they're present and nests all generated files under the main ReScript file. Adapt and tweak to your liking.

 ## Use with Other Editors
 
 This repo also contains a language server that can power other editors. **However, the language server in this project is a pure implementation detail. We don't guarantee its stability for other editors' consumption** apart from Vim and Sublime Text.
