 h2. Configuration file
 
-TO BE COMPLETED
+*dropsync* uses a YAML-formatted configuration file. It is mainly used to specify the list of files you would like to sync with your dropsync folder.
+
+The default location for this configuration file is @$HOME/.dropsyncrc.yaml@, where @$HOME@ is your home folder. This can be overriden using the @--config-file@ or @-f@ option when calling the @dropsync@ script.
+
+You can also use it to change some parameters (like the location of your Dropbox folder, or the name of the dropsync folder) to non-default values.
+
+An example of configuration is given in the @dropsyncrc.yaml@ file.
