	### STEPS TO UPLOAD NEW VERSION ###
	# in building branch
	# 1. set version='{{VERSION_PLACEHOLDER}}' # to make the version automatised by tag name through GitHub Actions
	# 2. git commit ... && git push # to upload everything that could be missing into the building branch
	# 3. git checkout main # to move to main branch
	# 4. git merge building # to merge all contents from building into main
	# 5. git tag $version # to create a tag with the new version's number, which will be used as VERSION_PLACEHOLDER
	# 6. git push origin --tags # to push merge and tag into GitHub
