+Configure Maven profiles
+------------------------

+Develop LibrePlan in Eclipse using MySQL
+----------------------------------------
+
+* This tutorial works properly with PostgreSQL, but if you want to develop
+  LibrePlan using MySQL you have to do 2 small changes:
+
+  * In section `Configure project to run`_ you have to set the *Profiles* to:
+    ``dev,mysql,-userguide,-reports,-i18n``
+
+  * In section `Configure Maven profiles`_ you have to set *Active Maven
+    Profiles* to: ``dev,mysql,-userguide,-reports,-i18n``
+
+* Remember that the three last profiles that are being disabled is just to save
+  compilation time and not mandatory. However, to develop using MySQL you have
+  to set at least the first two: ``dev`` and ``mysql``.
