So finally Community Pack idea materialized :)
Big thanks go to NoProsNoNoobs for adding support for following games:
- Fallout 4
- Fallout 76
- Fallout New Vegas
He was rewarded with Special Edition DLC key for this effort.
If you want to get some keys for free, this is one option.

Along with Community Pack comes version 1.6.
Support for Community Pack distributed via Steam system was added.
Custom Community Pack via URL set in options is still supported,
but new way is official way.
Modding documentation was updated based on NoProsNoNoobs experience
with adding support for games.
