ChronoChat Manual
===================================================================

**Step 0**: Before open ChronoChat, make sure ndnd is running on your machine. 
If you have installed `NDNx Control Center`_, check if its tray icon shows up

You also need to have your default key generated and certificate installed.
To check that, you can use a command line tool **ndnsec-ls-identity**, and you should see output similar to:

If you see nothing or something different in output, please go to `NDN Certifications`_ to set up your security environment.

**Step 1**: When you open ChronoChat App, you should see a contact panel as shown below.

The left part of the panel is your contact list. 
One must be one of your contacts if she/he wants to have a chat with you.
Right now, it is empty, so let's add some contacts. 

**Step 2**: Click the **Add** button in the lower left corner. 
You should see a contact browsing dialog which collects all the existing contact certificate in the testbed, for example:

You can select the contact you want to add, and then click the **Add** button.
Then you should see that the selected contact has been added into your contact list.
