+### Docker
+
+You can build and run the docker file from the `/backend` directory:
+
+```bash
+docker build . -t wandb/openui --load
+docker run -p 7878:7878 -e OPENAI_API_KEY wandb/openui
+```
+
 Now you can goto [http://localhost:7878](http://localhost:7878)
 
 ## Development
 
-See the readmes in the [frontend](./frontend/README.md) and [backend](./backend/README.md) directories.
+A [https://github.com/wandb/openui/blob/main/.devcontainer/devcontainer.json](dev container) is configured in this repository which is the quickest way to get started.
+
+### Codespace
 
+Choose more options when creating a Codespace, then select **New with options...**.  Select the US West region if you want a really fast boot time.  You'll also want to configure your OPENAI_API_KEY secret or just set it to `xxx` if you want to try Ollama (you'll want at least 16GB of Ram).
 
+![New with options...](./assets/codespace.gif)
 
+Once inside the code space you can run the server in one terminal: `python -m openui --dev`.  Then in a new terminal:
+
+```bash
+cd /workspace/openui/frontend
+npm run dev
+```
+
+This should open another service on port 5173, that's the service you'll want to visit.  All changes to both the frontend and backend will automatically be reloaded and reflected in your browser.

 ## Usage
 
+You must set the `OPENAI_API_KEY` even if you just want to try Ollama models.  Just set it to `xxx` in that case like below.
+
+```bash
+OPENAI_API_KEY=xxx python -m openui
+```
