1. Download & Install Sublime Text 3 (https://www.sublimetext.com/3)
2. Go to the menu Tools -> Install Package Control, then, wait few seconds until the installation finishes up
3. Now, Go to the menu Preferences -> Package Control
4. Type Add Channel on the opened quick panel and press Enter
5. Then, input the following address and press Enter

   https://raw.githubusercontent.com/evandrocoan/StudioChannel/master/channel.json
   

6. Go to the menu Tools -> Command Palette... (Ctrl+Shift+P)
7. Type Preferences: Package Control Settings – User on the opened quick panel and press Enter
8. Then, find the following setting on your Package Control.sublime-settings file:

   "channels":
   [
       "https://packagecontrol.io/channel_v3.json",
       "https://raw.githubusercontent.com/evandrocoan/StudioChannel/master/channel.json",
   ],

9. And, change it to the following, i.e., put the https://raw.githubusercontent... line as first:

   "channels":
   [
       "https://raw.githubusercontent.com/evandrocoan/StudioChannel/master/channel.json",
       "https://packagecontrol.io/channel_v3.json",
   ],

   • The https://raw.githubusercontent... line must to be added before the https://packagecontrol.io... one, otherwise, you will not install this forked version of the package, but the original available on the Package Control default channel https://packagecontrol.io...
