# This workflow should run for any push which is a preview build.
# Preview builds are indicated with a tag that ends in -preview
# In order to effect this, you can do the following:
#  scripts/tag-preview-build
# If you want to replace a build, you can use -f and then
# push the update to the tag like push -f origin <tag>,
# although this should never be done!
