Git's configuration is stored in plain text files and works like a key-value storage. You can set/query by key and get the value back. An example of the text-based configuration file is shown as follows (from the jgit repository):
$ cat .git/config
[core]
repositoryformatversion = 0
filemode = false
bare = false
logallrefupdates = true
[remote "origin"]
url = https://git.eclipse.org/r/jgit/jgit
fetch = +refs/heads/*:refs/remotes/origin/*
[branch "master"]
remote = origin
merge = refs/heads/master
