You'll see a Launcher Properties dialog box appear. Type a name for your app then click the browse button:
Select your pycharm.sh file in the Choose a command screen that appears when you click Browse. Click OK on the Choose a command screen (the one below the Launcher Properties box in the screenshot above)
Click OK on the Launcher Properties dialog box:
You should see a new icon on your desktop. Double click this icon to launch PyCharm. You can now go on to the lesson about launching PyCharm, and get a first look at it.
