-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
-
-.. _NDNx Control Center: http://named-data.net/download/
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/ncc.png
-
-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:
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/ndnsec-ls-identity.png
-
-If you see nothing or something different in output, please go to `NDN Certifications`_ to set up your security environment.
-
-.. _NDN Certifications: http://ndncert.named-data.net/
-
-**Step 1**: When you open ChronoChat App, you should see a contact panel as shown below.
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/chronochat-1.png
-
-You should see **Setting** button at the bottom of the panel.
-You can change your identity and setting there.
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/setting-dialog.png
-
-The default setting is derived from the key and certificate you installed in step 0.
-
-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.
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/chronochat-2.png
-
-**Step 2**: Click the **Add** button in the lower left corner.
-You should see a "Browse Contact" dialog which collects all the existing contact certificate in the testbed, for example:
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/browse-contact-1.png
-
-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.
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/chronochat-3.png
-
-If you know a contact's certificate name, you can add it directly via **Direct Add** button.
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/browse-contact-2.png
-
-You should see an "Add Contact" dialog, you can directly input the contact certificate name (without version number, e.g., /ndn/edu/ucla/KEY/cs/afanasev/ksk-1383327806/ID-CERT) into the **Contact** line, and then click **Fetch** button.
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/add-contact-1.png
-
-If the certificate can be fetched and verified, the dialog will show you the description about the certificate subject.
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/add-contact-2.png
-
-You can click **Add** to add the contact into contact list.
-
-**Step 3**: Now you can start a chatting room with you contacts.
-You can right click the contact you want to chat, and then select **Chat**.
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/chronochat-4.png
-
-You should see a "Start Chating" dialog:
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/start-chat.png
-
-You can click **OK** button, and then you will enter the chat room, and a chat invitation will be sent to the contact.
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/chatdialog-1.png
-
-If you see some red warning at the top of your chatroom window, such as:
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/chatdialog-3.png
-
-You can click the tray icon of the chat room to update your local prefix, such as:
-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/update-prefix.png
-

-

-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/invitation-notify.png

-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/chatdialog-2.png
-

-
-.. image:: https://raw.github.com/bruinfish/ChronoChat-V2/master/doc/img/chatdialog-4.png
