this is the first time i am trying to make wordpress theme and i have made it all but i am stuck on page builder. I want my user to edit my theme with wp bakery page builder. I have seen many videos and read many blogs but no one satisfied me because my question is very simple. I want to integrate wpbakery page builder in my theme so when someone download my theme, the wpbakery page builder should download automatically. to get this what should i do ? i saw some themes have this option when i download their themes there was wpbakery page builder already in the theme. how are they achieving this ? I am sorry i am asking silly question but i did not find this answer in any platform. please share some links too so i can learn this.
TGM plugin is generally used in many themes to define suggested and required plugins for themes.
You can find the GitHub Repo here: https://github.com/TGMPA/TGM-Plugin-Activation and check the example.php file to understand the implementation based on external and internal plugin zip files.
You can also read the installation process here http://tgmpluginactivation.com/installation/
Or you can check the source code of other themes that use TGM plugin, and you can learn the code writing from those themes.
