               GNU Image Manipulation Program
                   3.0 Release Candidate
               ------------------------------

This is a release candidate for upcoming version 3.0.0 of GIMP. This is not considered stable yet, unless testing tell us it is. Therefore save your work early and often. If you want a stable version, please use GIMP 2.10 instead.

If you think you found a bug in this version, please report it! We are at the verge of releasing the next major version of GIMP, so any report helps.

If you want to hack on GIMP, please read the file devel-docs/README.md. For detailed installation instructions, see the file INSTALL.

1. Web Resources

GIMP’s home page is at:

https://www.gimp.org/

Please be sure to visit this site for information, documentation, tutorials, news, etc. All things GIMP-ish are available from there.

The latest version of GIMP can be found at:

https://www.gimp.org/downloads/

We also have a website dedicated to documentation at:

    https://docs.gimp.org/

2. Contributing

GIMP source code can be found at:

https://gitlab.gnome.org/GNOME/gimp/

Resources for contributors:

    https://developer.gimp.org/

In particular, you may want to look in the “Core Development” section. Some articles of particular interest for newcomers could be:

• Setting up your developer environment: https://developer.gimp.org/core/setup/
• GIMP Coding Style: https://developer.gimp.org/core/coding_style/
• Submit your first patch: https://developer.gimp.org/core/submit-patch/

3. Discussion Channels

We have several discussion channels dedicated to GIMP user and development discussion. There is more info at:

    https://www.gimp.org/discuss.html

For the real junkies, there are IRC channels (e.g. #gimp or #gimp-user) devoted to GIMP on GIMPNet (a private free software oriented network). Many of the developers hang out there. Some of the GIMPNet servers are:

irc.gimp.org:6667
irc.us.gimp.org:6667
irc.eu.gimp.org:6667

More discussion channels, such as forums, will be listed on the above “discuss” page when they are moderated by a team member. Links to archives of former discussion methods (e.g. mailing lists) are also included in that page.

4. Customizing

The look of GIMP’s interface can be customized like any other GTK+ app by editing files in ${XDG_CONFIG_HOME}/gtk-3.0/ (settings.ini and gtk.css in particular) or by using “themes” (ready-made customizations). Additionally, GIMP reads ${XDG_CONFIG_HOME}/GIMP/2.99/gimp.css so you can have settings that only apply to GIMP.

You can also manually change the keybindings to any of your choice by editing: ${XDG_CONFIG_HOME}/GIMP/2.99/shortcutsrc.

Have fun,
