+# Run it with `yarn update:vscode` and it will do the following:
+# 1. Check that you have a remote called `vscode`
+# 2. Ask you which version you want to upgrade to
+# 3. Grab the exact version from the package.json i.e. 1.53.2
+# 4. Fetch the vscode remote branches to run the subtree update
+# 5. Run the subtree update and pull in the vscode update
+# 6. Commit the changes (including merge conflicts)
+# 7. Open a draft PR
