+#### NPX
+
+If you use the default package spec of `@azure/mcp@latest`, npx will look for a new version on each server start. If you use just `@azure/mcp`, npx will continue to use its cached version until its cache is cleared.
+
+#### NPM
+
+If you globally install the cli via `npm install -g @azure/mcp` it will use the installed version until you manually update it with `npm update -g @azure/mcp`.
+
+#### Docker
+
+There is no version update built into the docker image.  To update, just pull the latest from the repo and repeat the [docker installation instructions](#docker-install).
+
+#### VS Code
+
+Installation in VS Code should be in one of the previous forms and the update instructions are the same. If you installed the mcp server with the `npx` command and  `-y @azure/mcp@latest` args, npx will check for package updates each time VS Code starts the server. Using a docker container in VS Code has the same no-update limitation described above.
