+Please be warned that at this point the JabberSpam blacklist is the only list that will be utilized. It is planed to
+open up the tool to also import other lists in the future.

+### install
+The tool can be installed easily via that Python package installer (pip). After that the local wrapper `/usr/bin/bl-imp`
+can be called to use the module.

-##### *ejabberd reload_config*
-The ejabberd instance will be reloaded automatically, but only if changes in the `outfile` occurred.
+### ejabberd configuration
+To fully utilize the tool some configuration changes are required.
+It is required that the tool is the only one editing the defined yml file. It is required because any local change not
+present in the remote list will be overwritten automatically.
+Furthermore it is necessary for the file to be separate from the "main" ejabberd configuration file e.g `ejabberd.yml`.
+To further protect the integrity of your config the `allow_only` sections defines only `acl` rules.
 
-## configuration
-### ejabberd
-To use this script properly, you need to add this line to the `ACL` section of your ejabberd instance. Furthermore a 
-separate `yml` file is necessary. To further protect the integrity of your config the `allow_only` sections defines only `acl` rules.
+#### ejabberd acl config
 ```yaml
-  "/etc/ejabberd/blacklist.yml":

-      - acl

+  "/etc/ejabberd/blacklist.yml":   <-- the path is completely user configurable
