I wrote this as part of a blog post about yard & thought it might help someone else out.
Before you start, you will need to have
puma-dev setup on your local machine. Next run:
This will run bundle, build the documentation and link the directory in puma dev.
Now whenever you visit yard-docs.test, it'll return the documentation for all your locally installed gems.
I made this to scratch my own itch, so I'd love to hear if it helps anyone else. If anyone is interested I'd love to find a way to add some quick lookup that integrates nicely with Firefox.
