1) Developer SDK
I'm generating the skeletons of my plugins via "Create a Package". Since it creates a .tar file for each plugin, I assume my next step is to add the plugin skeleton through the Manage PLugins page of the admin?
Y / N
2) Adding pieces
Whether the answer above was yes or no (in such case I had to decompressed the .tar file and to add all folders and files manually) a lot of elements are obviously missing and I will have to add them bit by bit as I develop.
I assume that throughout the development, as I add controllers, models etc, I will be adding tables to the DB manually, as well as elements inside the manifest.php file. Correct? Y/N
I also assume that I can leave alone: the instal.php file, the my.sql file and the json file inside /packages, as those seem to be only involved during initial installation of a completed plugin
Or do I also have to keep constantly updating the instal.php file, the my.sql file and the json file inside packages?
