Can I create my own remote server instead of using GitHub?
i.e Can I make a remote server on LAN where 3 computers are sharing a drive on a network to do the collaborative work using Gitbash?
There are several ways to do this
mkdir -p RepoName && git init RepoName --bare
git daemon --base-path=$PWD/RepoName
git remote add origin git://server.url.or.ip/RepoName
git clone git://server.url.or.ip/RepoName
