How to install Telegram Desktop in Ubuntu 14.04

Download the Telegram Desktop client and extract tsetup.0.6.15.tar.xz. You can easily do this in the file manager (nautilus). Just right-click the file and click extract here. Now you have a folder called Telegram.
Move this folder to /opt.

sudo cp -R /home/dark/Downloads/Telegram /opt

You can do this using the file manager, but you'll need to start it with root privileges. You can do this by typing the following in a terminal: (you can find the "opt" folder in "computer")

sudo nautilus

After the move, double-click the telegram binary /opt/Telegram/Telegram. The last thing we need to do is add Telegram to the "applications" menu. This happens automatically if you right-click the icon of the running app and choose "lock to launcher".
