In 2017, it is well worth investing your time in understanding git and what it is.

For one, try treating it as a patch management system. Each patch is a commit*.

Each patch is "content addressable" (named after a SHA1 hash of the patch's contents and headers) and some have aliases (tags, branches, remote branches). Most patches/commits have one parent, some have two or zero. If a commit is not findable via an alias/ref, it can get garbage collected.

Remote branches (e.g. refs/remotes/origin/master a.k.a. origin/master) can sometimes have a declared relationship with a local branch (origin/master).

Don't be too afraid to look into .git folder either, or even edit some of the files manually. I like to undo some mistakes by editing .git/refs files directly.

Go on from there, read some "bottoms-up" descriptions, and you'll be on your way. Git's CLI is pretty bad, but try not to think of it as anything but a wrapper around a syncable patch directory.

SVN frontend can be a useful hack, but long term you should not rely on it. Having it is a useful bonus. But in 2017, don't expect you can avoid Git. And consider that use of such a frontend leads to data loss (given that git has more expressive relationships between commits).

* Technically, there's "objects" somehow representing files and whatnot, that are the actual parts of commits. For my understanding, however, thinking of it as patch files which get hashed like in a content addressable system is good enough.

Git repositories that support SVN clients merit consideration because

(a) some tools have SVN clients and not Git,

(b) some people understand SVN better than Git, and

(c) they bridge the two paradigms, giving more freedom (and time to shift when one wants to shift).
