+           ## Good First Issue
+
+            This item was marked as a good first issue or help wanted. Because of the following:
+
+            - It's self contained as a single feature or change.
+            - Is clear when it's complete.
+            - You do not need deep knowledge of Owncast to accomplish it.
+            - 
+
+            ### Next Steps

+
+            ### Notes
+
+            - Current web work is taking place in the [`webv2` branch](https://github.com/owncast/owncast/tree/webv2) and it is very much work in progress. Read the [README](https://github.com/owncast/owncast/blob/webv2/web/README.md) for this branch to get the web project running. But it's mostly just a `npm install` and `npm run dev`.
+            - We use Storybook for testing and developing React components. `npm run storybook`.
+            - If you need to install the Go programming language to run the Owncast backend it's simple from [here](https://go.dev/dl/).
