How to connect from windows command prompt to mysql command line

The cd in your question is invalid 

cd CD:\MYSQL\bin\

You can't cd to CD:\ anything, because CD:\ isn't a valid directory in Windows. CD: would indicate a drive, except that drives are restricted to a single letter between A and Z. 

If your \MYSQL\BIN is on drive C:, then your commands need to be:

C:\>cd \MYSQL\Bin

C:\MYSQL\Bin>mysql -u root -p admin

-

If you're not already on C: (which you'll know by looking at the prompt in the cmd window), or your MySQL folder is on another drive (for instance, D:), change to that drive too:

C:\> cd /d D:\MYSQL\Bin

D:\MYSQL\Bin>mysql -u root -p admin

-

The .exe after mysql is optional, since .exe is an executable extension on Windows. If you type mysql, Windows will automatically look for an executable file with that name and run it if it finds it.

Then, while inside the project's folder, do an initial commit:

$ git init

then for using bitbucket or such you add a remote and push up

$ git remote add some_name user@host:repo
$ git push some_name

you also might then want to configure tracking branches etc. see git remote set-branches and related commands for that.
