==== Access to OHDSI project source code ====
Github is the source control repository for all OHDSI projects.

Here is the main URL for OHDSI Github projects: [[https://github.com/OHDSI]]

==== OHDSI collaborative development model ====
OHDSI developers use [[https://guides.github.com/introduction/flow/index.html|Github flow]] with the fork and pull collaborative development model.

Here is a good [[https://guides.github.com/activities/hello-world/|"Hello World" example]] but note that in the fork and pull model, unless you are the project maintainer, you will need to first fork the project master branch and then create a new branch for your change on your forked copy.  Your pull request then triggers the project maintainer to merge your forked project branch back into the main project master.

==== Github Windows Client ====
If you develop on Windows, you can download the [[https://windows.github.com/|Github for Windows Client]].  There is a good [[https://windows.github.com/help.html|Windows Github client guide]] with helpful info on cloning repositories and branching locally using the Windows client.
