kimadeline · web-flow · commit 7fbd614c7d10 · 2020-02-13T11:20:59.000-08:00
* Prep for testing the workflow while working on it
* Don't need any job to test tag pushing
* Alright let's try it
* Forgot the syntax for multiline commands lol
* Try removing slashes
* Indentation?
* Change the way we refer to the sha
* Remove unnecessary document pipe
* Remove extra comma
* Delete the tag, i don't want it on my fork lol
* No need for checkout step
* Uncomment conditions + run tagging on main repo
* Forgot to undo testing changes, clarify comments
