+## How to install PWA
+
+To install the code-server PWA, follow these steps:
+
+1. Open code-server in Safari
+2. Click the Share icon
+3. Click "Add to Home Screen"
+
+Now when you open code-server from the home screen, you will be using the PWA.
+The advantages of this are more screen real estate and access to top-level keyboard shortcuts because it's running like an app.
+An example shortcut is the `cmd+w` to close an active file in the workbench. You can add this to your `keybindings.json` by doing the following:
+
+1. Open up code-serer
+2. `Command Palette > Open Keyboard Shortcuts (JSON)`
+3. Add the following to your `keybindings.json`
+
+```json
+{
+  "key": "cmd+w",
+  "command": "workbench.action.closeActiveEditor"
+}
+```
+
+Test out command by hitting `cmd+w` to close an active file
