+# Continuous Integration
+
+Work on our continuous integration goes forward. We now implemented
+automatic compilation of the main development branch both with the
+legacy `autotools` build system and the new `meson` one. We also produce
+an alternative build with the `Clang` compiler (additionally to the GNU
+compiler `gcc`).
+
+Moreover, for cross-platform development, we now produce Windows builds
+, both for 32-bit and 64-bit, cross-compiled with the
+`crossroad`/`Mingw-w64` tools.
+
+All these automatic builds allow us to catch early on specific bugs
+which may affect only certain configurations or platforms.
+
+We hope it could also attract new developers wishing to dabble in
+contributing. Looking at compilation warnings and trying to fix them may
+be a very good first step into GIMP code. It would be much less
+overwhelming than actually trying to dive into our huge code from
+scratch.
+
+If you are interested, look into our [CI
+pipelines](https://gitlab.gnome.org/GNOME/gimp/pipelines) and look at
+the last ones (preferably the `master` branch), then into one of the
+various compilation jobs. We will be waiting for your
+[patches](https://gitlab.gnome.org/GNOME/gimp/merge_requests)!
