-Now lets login to the Global Node. Your command prompt should be similar to "[username@GN0]" for confirmation. There are a few important files to note on this machine. The file {{{ /usr/local/etc/node.info }}} contains information about your slice and what services it's using. This file can be found on any Global Node as it is created during the Instrumentation process. The file {{{ /usr/local/etc/certs/unis-proxy.pem }}} is the key, cert used to query the UNIS API, which is also created during the Instrumentation process.

 If you're going to be using a command line tool, such as curl, you will need to follow this structure to retrieve information from UNIS. Fortunately, we provide a python script [https://github.com/periscope-ps/unis/blob/master/example/unis_client.py] to help facilitate this process. 
 
-If you would like to try a tool that handles your key, cert and slice uuid for you then you will need to install a dependency on the Global Node. For this example my Global Node is Fedora 15 but if you're using another image you can see more installation instructions here [https://github.com/periscope-ps/periscope/tree/master/peri-js].

+Upon starting this tool you will see the UNIS instance you are connecting to, the MS store instance, and various information about the Global Node. The Peri-JS tool is RESTful API itself that represents your subsection of UNIS. You can query this tool using the browser or command line.

+Either way, when you request this URL you will see a list of routes you can query. These routes accept the same HTTP verbs as the UNIS and MS API's but Peri-JS only display the data for your slice.
