Older version of a git repository as a submodule

Question

How can I add an older version of a repository as a submodule to my github repo?

I'd like to use abraham/twitteroauth's older 0.5.0 version, which is compatible with php 5.3.

This just add the last version:

git submodule add <path>
git submodule init
git submodule update

which is not what I need.

Answer 1

Go into the submodule, checkout 0.5.0, and commit.

git submodule add https://github.com/abraham/twitteroauth.git twitteroauth
cd twitteroauth
git checkout 0.5.0
git commit -a

The commit will show a change to twitteroauth recording the 0.5.0 commit it's now at.

diff --git a/twitteroauth b/twitteroauth
