What's [scanned]?

The model employed by git is not "client working with centralized server".
On whichever machine you want to be recording your changes (aka "running
'git commit'"), you would need to have git installed.

git is a distributed source code management system.  People often deploy
one (or more, in hierarchical fashion in an advanced set-up) bare server
repository for everybody to meet and synchronize.  Each developer has one
repository (or more) on his or her own on his or her machines.  Most
notably, if you work on your notebook and on your desktop (i.e. two
machines), you will have (at least) one repository on each of them [*1*].

I do not know about github in particular (that's #github question) but in
principle, yes.  Easy exchange of development histories across
repositories is the whole point of distributedness.

You can graft the older ones behind the root commit and filter-branch the
result to cast the graft in stone.  You are strongly recommended to do
that in one repository first, and have reasonable level of confidence in
the result before you publish it to other repositories, as running
filter-branch to rewrite the history after people (or yourself) cloned the
history to multiple places would cause trouble to thoese .

For more details, see the user-manual.  Don't dive into manual pages for
individual commands, which are for people who already understood the basic
concepts in the user manual.

*1* Maybe we should change our pricing structure to be based on the number
of repositories, not on the number of users.  Currently we charge $0 per
user, but we should change $0 per repository ;-)
