Usage issues

[r0mflip]

I tried to use the build action to deploy my site https://github.com/r0mflip/jsdiff.netlify.com and I faced a few problems in the process:

Initially I created an empty site(not from git) and then used the actions to trigger a build, but it didn't work because the site wasn't linked. I then had to try various methods to trigger a build (commits at https://github.com/r0mflip/jsdiff.netlify.com/commits/master) and finally realized it.

I then got a new site to work from the actions performing there step-by-step:

1. New site, actions don't work yet
2. Link continuous integration(repo)
3. Let a build run
4. Remove netlify access to the repo (to disable deploys on normal push, disables the hook), and build settings can be removed from settings (don't remove/change repo url) apparently "auto publishing" and build commands should be left as-is to work
5. Finally trigger builds using actions (specify build opts)

I think that the linking and un-linking process should be documented so that users creating a new site from empty folder can get actions working.
