+### Creating a GH release
+This section guides you through how to create a new release. Let's assume the current version is `0.1.3` and you want to release `0.2.0`.
+
+ - Make sure the `main` state represents what you want to release and you're on `main`.
+ - Prepare a release-candidate build on a branch:
+```bash
+git branch 0.2.0-rc \
+&& git checkout 0.2.0-rc
+```
+ - Bump up the version number. It must be a valid [semver](https://semver.org/) and must be greater than the current one:
+```bash
+yarn update:version 0.2.0
+```
+ - This should generate multiple outgoing changes with the version update.
+ - Commit your changes and push to the remote:
+```bash
+git add . \
+&& git commit -s -m "Updated versions to 0.2.0" \
+&& git push
+```
+ - Create the GH PR the workflow starts automatically.
+ - Once you're happy with the RC, merge the changes to the `main`.
+ - Create a tag and push it:
+```bash
+git tag -a 0.2.0 -m "0.2.0" \
+&& git push origin 0.2.0
+```
+ - The release build starts automatically and uploads the artifacts with the changelog to the Pro IDE [release page](https://github.com/arduino/arduino-ide/releases).
+ - If you do not want to release the `EXE` and `MSI` installers, wipe them manually.
+ - If you do not like the generated changelog, modify it and update the GH release.
