+## Editing y(a)ml files with VSCode
+
+If you already use vscode as your editor you are in luck. Steffano wrote a very handy how-to setup run-on-save extesion for vscode.

+
+
+If you want to use the prepend parameter so you can use a parent document (components.yml) with all your components defined you could do the following.
+
+```yaml
+"settings": {
+    "emeraldwalk.runonsave": {
+        "commands": [
+            {
+                "match": "\\.yml$",
+                "cmd": "wireviz --prepend  components.yml ${file} -f h"
+            },
+            
+        ]
+    }
+}
+```
+
+(the -f h instructs wireviz to only produce a html file. Do a wireviz -h for a overview of all the parameters)
