If you're a fan of the CodeIgniter framework and have spotted a place in its manual that things maybe could be explained better (or that there's an error), you'll need to go through the process of getting it updated. In this new post to his blog Derek Allard (of EllisLabs) looks at the best way to do it.
What I'd like to focus on here is how to go about improving the docs, and one approach to giving your suggestion the best possible chance of getting included. The first thing to understand about our docs is that currently they are not editable by the community. This means all doc changes need to go through a staff member. There are advantages and drawbacks to this, but for now that is the way it works.
You'll need to contact him or another staffer at EllisLabs to submit the change. Derek suggests a few ways to make sure your submission is considered like being polite, save time by formatting it ahead of time and keep the items requested to a minimum. To submit your updates, you can submit them here.
