As a native French speaker: very good translation.

One small point: I do not understand why you added "it" to the last sentence of the introduction. Your translation of that particular sentence feels weird to me, why not simply:

"And source code belongs in source control."

Also, maybe "différentes" (in the third sentence) could have been translated to "various"?

Aside, note that the original text itself has several errors. Many accents are missing, some letters or words are missing or doubled. I may submit a PR to correct them.

Moreover, the text includes many English words (not all of which are common in French). It even includes a barbarism: "tracker", from English "track" and French common verbal suffix "-er", supposedly a verb supposed to mean "to track" — a shame, since French has the verb "traquer" to express the same thing.

You're right, of course. That was left over when I switched from "it goes in" to "it belongs in". Fixed!

For "les différentes assemblées", would you say "various assembliess" or "the various assemblies" in this context?

In this context, I would definitely say "the various assemblies" since the author is obviously designating the various assemblies working on the Civil Code, not a random ensemble of assemblies.
