I want to install the transcription program "f4 trankript" - here a link to their website:
https://www.audiotranskription.de/english/downloads
Sadly I have no clue how to do it.

I've looked into a few options, but the software isnt in the Software Manager.
To the best of my knowledge therefor I cant use apt-get
(even though I'm not sure, wether I have the right package name - I just used the title from my downloads: f4transkript-7.0.6-linux.tar.gz).
Also I think, that I cant use the Synaptic Package Manager for the same reason, right?
So is this "PPA repository" thing my last option, because I'm pretty sure, that I dont have the skills or the understanding to do it.

Do you know, how I can install f4 transkript?
And if so - can you give me a step-by-step explanation on how to do it?
thanks in advance ♥
