问题
Is there a way to download a particular version of a branch?
In particular I'd like to do a git clone of https://github.com/Theano/Theano now, and save a set of instructions on how to get the exact same version from github, regardless of future commits.

UPDATE
There is an easier way to do this on github if no further changes are expected. In github, you can navigate to the 'tree view' of a repository from your browser via the URL
https://github.com/<repo_name>/tree/<commit_sha>
Clicking on the 'Download ZIP' button on the right-hand navigation bar will download the codes of the repository up to that particular commit.
ORIGINAL ANSWER
I think one way to make your user's (or whoever will be reading your instructions) life easier is to clone the entire repository as-is. Then if the current HEAD commit is the version you want and you don't plan on making/merging changes to your repository, you can just refer your user to this new repository; probably tagging it will be a good idea.
Otherwise, you can create a branch (and a tag) in your new repository with the specific commit by doing:
$ git checkout -b new_branch commit_sha // where commit_sha points to the version you wanted
Then you can refer your user to this new branch (or tag) in your repository, after they have cloned your repository.
I don't think there is a simple way to clone the original repository from an old commit without using git reset.
