+  rosrun roslisp_repl repl
+  # Now load the ros-cl-mongo package and interact with the database using it
+Further usage instructions on cl-mongo are available at [[https://github.com/fons/cl-mongo|https://github.com/fons/cl-mongo]]
 ==== Locating the Database ====
-The database is by default located in /usr/var/
+The database is by default located in ''/var/lib/mongodb/'' where you are able to notice the databases named ``roslog.1`` etc. The mongo client knows about this path so starting mongo from any resonable location will still access this databases. Of course this path can be changed using the ''--dbpath'' flag on mongo to change where to read or write. In summary the database features of importance are;
+  * Hostname : localhost (by default)
+  * Port: 27017 (default)
+  * Locatation: ''/var/lib/mongodb/''
+==== Examples of usage ====
+We have compiled simple example of logging with this tool and querying the data using either lisp or python. The examples are in the links below:
