+### Various administration tricks
+
+#### Default sharing level
+
+Choose your default sharing level to match your usage scenario for MISP. The setting is named *default_event_distribution* and the values can be:
+
+*   Your organisation only (default)
+*   This community only
+*   Connected communities
+*   All communities
+
+You can also set a default distribution level for attributes contained in an event with *default_attribute_distribution*, and it has the same values as the default sharing level for events plus an additional one that allows attributes to inherit the sharing level of the event.
+
+#### Adding organisation logos
+
+You can add logo for organisations in MISP by uploading them via the tab **Manage files** under the **Administration** menu & **Server Settings** sub-menu.
+The filename must be exactly the same as the organisation name that you will use in MISP.
+It is recommended to use PNG files of 48x48 pixels.
+
+#### The \_schdlr\_ worker is not starting
+
+If you already made sure that you copied the config file under the cakeresque directory, it might be due to the FQDN of the server hosting the instance has changed. A way to fix this is to flush temporary data stored in redis. This can be done by logging in redis, for example when logging in with redis-cli, and issuing a flushall command.
