 1) How to build it
 ------------------
 
-This version is a stable version, which means that it belongs to a branch which
-will get some fixes for bugs as they are discovered. Versions which include the
-suffix "-dev" are development versions and should be avoided in production. If
-you are not used to build from sources or if you are not used to follow updates
-then it is recommended that instead you use the packages provided by your
-software vendor or Linux distribution. Most of them are taking this task
+This is a development version, so it is expected to break from time to time,
+to add and remove features without prior notification and it should not be used
+in production. If you are not used to build from sources or if you are not used
+to follow updates then it is recommended that instead you use the packages provided
+by your software vendor or Linux distribution. Most of them are taking this task
 seriously and are doing a good job at backporting important fixes. If for any
 reason you'd prefer a different version than the one packaged for your system,
 you want to be certain to have all the fixes or to get some commercial support,
