 ## Our Development Process
 Most of our work will be done in public directly on GitHub. There may be changes done through our internal source control, but it will be rare and only as needed.
 
+## Setup
+- Clone the project locally using `git clone`.
+- Fetch required submodules by running `git submodule update --init --recursive` in the directory.
+- `bundle install` to install necessary RubyGems.
+- Run `pod install` to fetch OCMock for testing.
