 ## Development
 
-If you are doing local development, there are two ways to test your changes:
+### Building
 
-1. Run the MCP inspector to test your changes. See [Debugging](#debugging) for run instructions.
+[`uv`](https://docs.astral.sh/uv/) is used for development. 
 
-2. Test using the Claude desktop app. Add the following to your `claude_desktop_config.json`:
+Start by creating a fresh virtual environment:
 
-### Docker
+```bash
+uv venv
+source .venv/bin/activate
+```
+To run the tests, type `uv run pytest`, to run the server from source use `uv run src/mcp_server_git/`. 
+
+To build, type `uv build`. You can then now run `mcp-server-git` command directly. Open with the inspector using `npx @modelcontextprotocol/inspector@latest mcp-server-git`.
+
+To specify the Python version type `uv python pin <version>` (useful if you want to use a more recent version than the default).
+
+To create the Docker container use
+
+```bash
+docker build -t mcp/git .
+```
+
+An example showing how to run via the Docker container is below:
