be 80 characters wide where it was possible. 80 characters
has been accepted for a long time as a good reading width.
It is also ideal when doing side-by-side code comparisons.

slight modification to the Recommended workflow
to add reviewers and address review feeback

Major update to the creating merge requests section:
the merge from issue was moved to method 1

Update a lot of the section trying to make it clearer what
steps should be taken.

Moved the "Completing merge requests" section to point 5. of the
merge from pushed branch section. The screen shots and
instruction were specific to the merge from a branch not a merge from an issue.

Added a little more documentation to the fork merge instructions
to make it clear it was not the prefered method.  Added some
reasons a developer may want to use a fork.

wide.

This removes the landing_page image people should be familar enough with registering for websites that the screen shot will not be needed.

Changed the paragraph instructions to list of instructions. Step by step lists are easyer to follow an less likely to cause confusion.
