Creating the parser for a new satellite downlink

Hello everyone, :blush:

I am new to this platform, and have just started learning the processes and how to contribute.
I encountered the process of creating a parser for a new satellite downlink and started reading through the steps. However, as I am new, I might have some confusions while I learn. So my first question is in the steps it says “Find and read documentation of the satellite downlink”. In the documentation tab of the site, I did not find any related to this. Could you please help me understand what I have to do for this?

Best Regards
