+## Auto-run with VSCode
+
+For VSCode the [Run on save](https://github.com/emeraldwalk/vscode-runonsave) extension can be used to trigger mktoc.
+
+Install the extension and then add the following config to workspace or user `settings.json`.
+
+```json
+"emeraldwalk.runonsave": {
+    "commands": [
+        {
+            "match": "\\.md$",
+            "cmd": "mktoc ${file}"
+        }
+    ]
+}
+```
+
+This will run the command for every markdown file on safe. If there is no mktoc comment in the Markdown file nothing happens.
+
 ## Performance
 
 `mktoc` is fast but can probably be even faster! Pull Requests and bug reports are appreciated!
