 ## Tips for bug reports
 
-* Always completely fill out the issue template that is automatically inserted
-  on issue creation.
+* Was this issue already reported?  Please do a quick search.
+* Maybe the problem is solved in the current master branch already?
+  Simply clone ranger with `git clone https://github.com/ranger/ranger` or
+  download the git version via https://github.com/ranger/ranger/archive/master.zip
+  and run `./ranger.py` directly to find out.
 * You can obtain much better error messages with `ranger --debug`, please post
   those in bug reports rather than the usual, single-line error message. Also
   check the log by using the default map `W` or by running the command `display_log`.
