 * **Do** list [verification steps](https://help.github.com/articles/writing-on-github#task-lists) so your code is testable.

 #### New Modules
 
 * **Do** run `tools/msftidy.rb` against your module and fix any errors or warnings that come up. Even better would be to set up `msftidy.rb` as a [pre-commit hook](https://github.com/rapid7/metasploit-framework/blob/master/tools/dev/pre-commit-hook.rb).

+* **Do** use the [many module mixin APIs](https://dev.metasploit.com/documents/api/). Wheel improvements are welcome; wheel reinventions, not so much.

 * **Do** write [RSpec](http://rspec.info/) tests - even the smallest change in library land can thoroughly screw things up.
 * **Do** follow [Better Specs](http://betterspecs.org/) - it's like the style guide for specs.
 * **Do** write [YARD](http://yardoc.org/) documentation - this makes it easier for people to use your code.
+* **Don't** fix a lot of things in one pull request. Small fixes are easier to validate.
