+A GitHub Action automagically publishes the extension to the Visual Studio Marketplace, on the release of a new GitHub Release.
 
-Ensure the `main` branch is checked out.
+1. Package a new version of the extension:
 
 ```bash
-git checkout main
+npm run pack -- <tag_type>
 ```
 
-Update the local repository with `upstream`, and reset `main`.
+Where `<tag_type>` is one of: `major`, `minor`, `patch`.
+
+2. Push the new version to `main`:
 
 ```bash
-git fetch upstream
-git reset --hard upstream/main
+git commit -am "<tag_type>(<version>): <description>"
+git push
 ```
 
-Checkout the `prod` branch.
+Optionally, you can push directly to `upstream/main`, but opening a new PR is recommended for a sanity check.
 
-```bash
-git checkout prod
-```
+3. Create a new GitHub Release using the GitHub UI:
 
-Merge the commits wanted for deployment into `prod`.
-
-```bash
-git merge main
-```
-
-Push the local branch to `upstream`.
-
-```bash
-git push upstream
-```

 > [!NOTE]
-> Pushing to `upstream` requires write access to the `freeCodeCamp/courses-vscode-extension` repository.
+> Creating a release requires write access to the `freeCodeCamp/courses-vscode-extension` repository.
