  ## Finding an issue
  -First, find an area to work on within the shell or one of it's related projects.
  +1. Find an area to work on within the shell or one of it's related projects.
  This may be:
  - An existing issue which has been reported
  - A feature that is missing that you would like to develop
  - An issue you've discovered that you would like to fix
  -Once you have found something that you want to work on, submit your intent to
  -the issue board, either by creating an issue for an issue which does not exist,
  -or commenting on an issue that you are working on it.
  +2. Submit your intent to the issue board. Write into an existing issue or create a new issue.
  ## On Unit & Integration Tests
  -Changes made to the code should normally be accompanied by both unit and integration tests,
  -in order to prevent these issues from re-occuring in the future.
  +Feature addition to the code should be accompanied by unit and integration tests,
  +in order to prevent issues from creating on refactoring in the future.
  +Bug fixes should be combined with regression tests in order to prevent issues from
  +re-occuring in the future.
  If you see an area that deserves a test, feel free to add extra tests in your pull requests.
  When submitting new functionality, especially complex functionality, try to write as many
  tests as you can think of to cover all possible code paths that your function(s) might take.

  +Integration tests are located in the **tests** directory, and are the most important place
  to create tests -- unit tests come second after the integration tests.
  +Regression tests are both integration and unit tests, depending on the bug.
  Integration tests are much more useful in general, as they cover real world use cases and
  stress larger portions of the code base at once. Yet unit tests still have their place, as
