[gimp-web/gimp-web-static] Explain *how* to contribute to the GIMP projects.

    Explain *how* to contribute to the GIMP projects.
    
    The "Development Status", "Bug Reports" and "Web Development" headings seemed to
    me like they were really subsections of "How You Can Help," so I set those to be
    h3 headings.
    
    A couple times, in the "Hacking" and "How To Submit Your Changes" sections, I
    tried to borrow the tone of Wikipedia's "Be Bold" guidelines.
    <https://en.wikipedia.org/wiki/Wikipedia:Be_bold>
    
    I added a list of links to the most important GIMP repositories. I was going to
    mention gimp-web-devel in this list, but it looks like no one has pushed any
    commits there since 2013. Perhaps that repo should be archived?

-## Bug Reports
+### Bug Reports
 
 GIMP is not a bug-free application nor is any other application so reporting the bugs that you will 
encounter is very important to the development, it helps the developers to make GIMP more stable and more bug 
free.
 
 You don't have to be a developer or a everyday user to report bugs. It can be hard to report a bug the first 
time you try it out but don't just quit the whole bug report if you think it is hard. Instead, look at the 
[bugs](/bugs/) page you will find some very good help about this.
 
-## Web Development
+### Web Development
 
 Creating websites that contain useful information is very important. It is actually just as important as 
doing bug reports. A website contains a lot of information that is needed for the development to move on and 
it also contains information that will help the public to understand what the application is all about.
 
 ## Hacking
 
-This is the part where people are always needed to help with the development, and this is also the part that 
is the hardest to start with. Though there are websites and files to give you a good look at how hacking is 
being done in GIMP.
+GIMP uses [git](https://git-scm.com/) as its revision control system, and the [GNOME 
Foundation](https://www.gnome.org/) hosts all of our code repositories:
+
+*   [`gimp`](https://git.gnome.org/browse/gimp/) - the GIMP application itself
+*   [`gimp-web`](https://git.gnome.org/browse/gimp-web/) - repo for this website
+*   [`gimp-web-devel`](https://git.gnome.org/browse/gimp-web-devel/) - repo for the developer site at 
<http://developer.gnome.org>
+*   [`gimp-help-2`](https://git.gnome.org/browse/gimp-help-2/) - the GIMP user manual
+*   [plus several others](https://git.gnome.org/browse/?q=gimp)
+
+New contributors should first introduce themselves on IRC (the #gimp channel at irc.gimp.org) and/or the 
relevant mailing lists:
+
+*   [GIMP Developers mailing list, for those who work on the core GIMP application and 
plugins](https://mail.gnome.org/mailman/listinfo/gimp-developer-lists)
+*   [GEGL Developers mailing list for developers of the GEGL 
library](https://mail.gnome.org/mailman/listinfo/gegl-developer-list)
+*   [GIMP Web Developers mailing list, for working on this 
website](https://mail.gnome.org/mailman/listinfo/gimp-web-list)
+*   [GIMP Documentation mailing list, for working on the user 
manual](https://mail.gnome.org/mailman/listinfo/gimp-docs-list)
+
+This way you can announce the changes you intend to make, ask questions, and discuss which changes would be 
best. It's generally better to focus on one thing at a time. Contributing to a software project for the first 
time is always the hardest part, which is why we're here to help each other. There are also websites to give 
you a good look at how hacking is being done in GIMP.
 
 The site you should keep updated with and the site that is updated all the time with new development help 
guides is located at [http://wiki.gimp.org/](http://wiki.gimp.org/). If you have GIMP installed at the moment 
then there are some files you should look at in the source code that might help you a little.

+
+## How To Submit Your Changes
+
+When you're ready, make your edits, and [generate a patch file](https://git-scm.com/docs/git-format-patch). 
Send the patch file, along with a summary of what you did, to the mailing list for feedback. The GIMP 
community is a friendly one, but it probably is still worth saying this: Try not to take critiques 
personally. We all just want GIMP to be the best that it can be. Once approved, your edits will be merged 
into the code base, making you an official GIMP contributor. And if you keep up the good work, not only will 
this process get easier with practice, your administrative privileges in GIMP development will also increase 
too.
