Make sure your install/build/test/run documentation is as thorough as possible--consider running through it with a friend who's using it for the first time, and note where they get stuck. Then fix.
Shove all of that step-by-step into its own .md file and include the link in your readme, to let readers know it's there.
Add a "Troubleshooting" guide and link to that from your Readme--don't post it as a section there. :)
Definitely add a Contributing.md so contributors know what you're looking for and how to contribute. Like the "Troubleshooting Guide," add a referencing section to it from the Readme with the link to the dedicated .md file.
No need to post the licensing section at the bottom -- you have the dedicated file there.
Hey there!
I'm looking for feedback in the ffind README page.
Thanks a lot in advance! This is a great initiative
Cheers, Jaime
