Subject: [alpine-aports] [PATCH] .github/CONTRIBUTING.md: Add 'Before you start making changes' section.

From: Przemyslaw Pawelczyk <[email-masked]>
Date: Wed, 18 Jan 2017 23:29:06 +0100

It's important to educate contributors to have a habit of being
up-to-date w/ aports repository and checking all places when people
submit patches, i.e. Patchwork and pull requests on GitHub.
It should greatly lessen the possibility of doing already done work.

+1. Check whether the change you want to introduce is not already present in the aports repository.  
+   Main aports repository can be cloned from: git://git.alpinelinux.org/aports  
+   There is also web frontend available at:  http://git.alpinelinux.org/cgit/aports  
+   GitHub mirror of aports repository:      https://github.com/alpinelinux/aports
+2. Check whether the change you want to introduce has not been already submitted by someone else.
+   - https://patchwork.alpinelinux.org/project/aports/list/
+   - https://github.com/alpinelinux/aports/pulls
+3. If you've found that someone already did what you wanted to do, then be patient. The change should be applied soon in the main repository, unless maintainers are busy or the patch needs to be improved.  
+   If it seems that your change won't be duplicating already done work, then please continue.
