+# Updating
+
+Cursorless consists of two components:
+
+- A VSCode extension, and
+- A set of Talon files to define the spoken commands
+
+## Updating the VSCode extension
+
+The VSCode extension will update automatically, unless for some reason you have auto-updating disabled, in which case you will have to [update the extension manually](https://code.visualstudio.com/docs/editor/extension-marketplace#_update-an-extension-manually).
+
+## Updating the Talon side
+
+The Talon side of Cursorless always needs to be updated manually by performing a `git pull` in the appropriate directory.
+
+### Linux & Mac
+
+Assuming the default install location of `~/.talon/user/cursorless-talon`:
+
+```bash
+cd ~/.talon/user/cursorless-talon
+git pull
+```
+
+### Windows
+
+Assuming the default install location of `%AppData%\Talon\user\cursorless-talon`:
+
+```batch
+cd %AppData%\Talon\user\cursorless-talon
+git pull
+```
