HOWTO.md

+Welcome to Free-Programming-Books! We welcome new contributors; even those making their very first pull request on Github. If you're one of those, here are some resources that might help:

+- https://guides.github.com/activities/hello-world/
+- https://help.github.com/articles/about-pull-requests/
+
+Don't hesitate to ask questions; every contributor started with a first PR. You could be our thousandth!
+
+Even if you're an experienced open source contributor, there are things that might trip you up. Once you've submitted your PR, Travis-CI will run a linter, often finding little issues with spacing an alphabetization. If you get a green button, everything is ready for review, but if not, click on the travis link to find out what the linter didn't like. Fix the problem and add a commit to your PR.
+
+Finally, read through the guidelines in [CONTRIBUTING](/CONTRIBUTING.md) if you're not sure if the resource you want to add is appropriate for Free-Programming-Books.
