+Basic Usage
+===========
+
+Initializing a store
+--------------------
+Before the first archive can be created a store needs to be initialized::
 
     $ darc init /data/my-backup.darc
     Initializing store "/data/my-backup.darc"
     Key file password (Leave blank for no password): *****
     Key file password again: *****
-    Key file "/Users/jonas/.darc/keys/data_my_backup_darc" created.
+    Key file "/home/YOU/.darc/keys/data_my_backup_darc" created.
     Remember that this file (and password) is needed to access your data. Keep it safe!
 
-Create an archive::
 
-    darc create -v /data/my-backup.darc::backup-2011-09-10 ~/Documents ~/src
+Archive creation
+----------------
+The following command will create a new archive called ``backup-2011-09-10`` containing
+all files in ``~/Documents`` and ``~/src``::
 
-Extract an archive::
+    $ darc create -v /data/my-backup.darc::backup-2011-09-10 ~/Documents ~/src
 
-    darc extract -v /data/my-backup.darc::backup-2011-09-10
+Extract an archive
+------------------
+The following command will extract the archive ``backup-2011-09-10``::
 
-Delete an archive::
+    $ darc extract -v /data/my-backup.darc::backup-2011-09-10
 
-    darc delete /data/my-backup.darc::backup-2011-09-10
+Delete an archive
+-----------------
+The following command will delete archive ``backup-2011-09-10``::
 
-List store contents::
+    $ darc delete /data/my-backup.darc::backup-2011-09-10
 
-    darc list /data/my-backup.darc
+List store contents
+-------------------
+The following command will list the names of all archives in the store::
 
-List archive contents::
+    $ darc list /data/my-backup.darc
+    backup-2011-09-09
+    backup-2011-09-10
+    ...
+
+List archive contents
+---------------------
+The following command will list the contents of the ``backup-2011-09-10`` archive::
+
+    $ darc list /data/my-backup.darc::backup-2011-09-10
+    -rw-r--r-- YOU    users       280 May 14  2010 home/YOU/Documents/something.txt
+    -rw-r--r-- YOU    users       280 May 14  2010 home/YOU/Documents/something-else.pdf
+    ...
+
+Purge old archives
+------------------
+When performing automatic backups it is important to periodically purge old backup
+archives to stop the store from growing too big.
+
+The following command will purge old archives and only keep the
+seven latest end of day archives and the five latest end of week archives::
+
+    $ darc purge --daily=7 --weekly=5 /data/my-backup.darc
 
-    darc list /data/my-backup.darc::backup-2011-09-10
