 By bundling the tags / attributes definitions together with the framework library, you ensure that users will always get the matching tags / attributes with the specific version of your library they are using.
 
+## Workspace Custom Tags
+
+You can define custom tags/attributes for your workspace by specifying a `vetur` key in package.json. For example, to get auto completion for tag `<foo-tag>`, all you need to do is:
+
+- Create a file `tags.json` with:
+
+  ```json
+  { "foo-bar": { "description": "A foo tag" } }
+  ```
+
+- Add this line to `package.json`:
+
+  ```json
+  {
+    "vetur": { "tags": "./tags.json" }
+  }
+  ```
+
+- Reload VS Code. You'll get `foo-bar` when completing `<|`.

 ## Adding a Framework
 
 If your Vue UI framework has a lot of users, we might consider bundling its support in Vetur. However, this means Vetur's definition for the framework might become outdated.
