    I would like to turn this into a git repository.  One branch being master,
    the second develop and finally a third branch that is extended off the
    develop branch.

I will assume in my instructions that develop is "extended" off of master.

----------------------------------------------------------------------
cd /path/to/new/master
# Make this a git repo
git init
# Add all files to git
git add .
# Commit all files to git
git commit -m "initial master version"
# Make new develop branch
git checkout -b develop
# Cause git to delete all files in the internal index
git read-tree --reset -i 4b825dc642cb6eb9a060e54bf8d69288fbee4904
# Cause git to delete all files in the working directory
git clean -dfx
# Copy all files from the develop directory
cp -r /path/to/new/develop .
# Add all files to git (and delete them too)
git add -A .
# Commit
git commit -m "Initial develop branch"
# Make new extended branch
git checkout -b extended
# Cause git to delete all files in the internal index
git read-tree --reset -i 4b825dc642cb6eb9a060e54bf8d69288fbee4904
# Cause git to delete all files in the working directory
git clean -dfx
# Copy all files from the extended directory
cp -r /path/to/new/extended .
# Add all files to git (and delete them too)
git add -A .
# Commit
git commit -m "Initial develop branch"

The only "magic" is the read-tree/git-clean stuff.  The 4b82… value is
the SHA of an empty tree.  It could be replaced by a:

find . -maxdepth 1 ! -name '.git' -a ! -name '..' -a ! -name '.' -print0 | xargs -0 rm -rf

But that is 9 extra characters.

Untested, but it should work.
