UNSOLVED Add standard module

[Serge]

Hello everyone!
I need to integrate few 3rd party modules to the MM core to appear them like a default modules.
I want to add the following:

• email-mirror https://github.com/ronny3050/email-mirror
• MMM-PIR-Sensor https://github.com/paviro/MMM-PIR-Sensor
• MMM-Remote-Control https://github.com/Jopyth/MMM-Remote-Control

to the MM installer as a default modules.

I see, that

• dependencies for default modules are stored within MagicMirror/node_modules while dependencies for 3rd party modules are stored within folder of each such module.
• default modules are stored in MagicMirror/Modules/default while 3rd party modules are stored within Modules/[Module_name].

I have forked the MM git, but can’t understand what to do next to make these 3 modules default for installation (I do not need to use installers/postinstall/postinstall.sh for this purposes as i need to appear these 3 modules as a default ones).

Is it easy to complete this task? I would be thankful for any ideas and thought.
