Very well. I also know nothing about github, so I can't help there
I'll give a short show of what can be expected to be translated in a quest file, to give some starting direction.
In every Daggerfall Unity installation, the quest files can be found in \DaggerfallUnity_Data\StreamingAssets\Quests. They are all simple .txt files that require nothing more than Notepad, or any other ordinary text editor. Each quest file has a name made of letters and numbers, but you can look up quests on the UESP
instead of manually searching each file one by one to find the right quest. Also note that the first letter of quest file names separates them among guilds, so quest files M_________.txt are Fighters Guild, N_________.txt are mages guild, and so on.
I'll copy here a regular quest file to show such things as can and should be translated.

<ce> The Mages Guild is in need
<ce> of someone to guard the
<ce> magical _treasure_ tonight.
<ce> Is it feasible that you could
<ce> do it for us? There's a
<ce> _potion_ in it for you.
<ce> The Guildhall -- how should one
<ce> put this? In life, I think you'll
<ce> agree, there are always some people
<ce> who just ... well, the Guild has
<ce> always stood for, or, rather, had
<ce> problems with ... Listen, young
<ce> %pct, we need a guard. Will you do it?
<ce> No problem. There are always
<ce> other guild members looking
<ce> for work.
<ce> Be at the Mages Guild
<ce> by midnight. Your period of
<ce> guardianship will last
<ce> until 3:00 in the morning.
<ce> Well done, %pcf. Those
<ce> thieves didn't stand a chance
<ce> against you. Here, take this
<ce> _potion_. It's
<ce> really the least we can do.
The thieves must think that _treasure_ in the Mages Guild is very valuable.
The thieves have been threatening to steal the Mages Guild's _treasure_.
The thieves finally got that _treasure_ after all.
The Mages Guild should've got real guards. That's why they lost the _treasure_
Those thieves aren't going to try to get that _treasure_ again, I bet.
The thieves who tried to get that _treasure_ didn't expect a real guard, I bet
How are you, %pcf? Found any use for that _potion_ yet?
<ce> The _treasure_ is gone,
<ce> but you're here? That's hardly an
<ce> equal exchange, I think.
<ce> Leave me, %pcn.
%qdt: I agreed
to guard a magic _treasure_
at the Mages Guild of
___qgiver_. I have
to be there between midnight
I couldn't resist it. I took
the _treasure_ I was
supposed to guard. They'll
be after me for sure.
<ce> Lookee here boys. A guard.
<ce> Gee, I'm all scared and
<ce> shaking. Lets leave the
<ce> tongue on the door as a
<ce> warning not to mess with
<ce> the thieves guild. Get him!
<ce> I claim bounty on the thief
<ce> and traitor to the Mages

Some quick tips: every line starting with a hyphen, -, is just a comment and is not used in the quest. Everything below the QBN statement, about halfway through the file, deals with quest mechanics and not dialogue, so there's no need to translate them. Whenever you see a line with <--->, that means Daggerfall could use either the message before or the message after for the text box, but it will not use both at the same time. Anything starting with %, like %pcn or %qdt, should not be altered. Anything starting and ending with underscores, like _potion_, should not be altered.
I've put in italics everything in this quest file that should be translated. No headers or titles should be translated. Everything after the QBN section is all mechanics, and therefore does not need to be translated.
So changing the dialogue is the work we have before us, in terms of quests.
Farewell DFU community! My time here has been a joy.
