+## Contributing
+To contribute to the site, you must be a part of SIGGraph UIUC:
+1. Make changes to https://github.com/SIGGraph-UIUC/siggraph, a fork of the original acm-uiuc repository
+2. Test those changes via `$ yarn run start` which creates a local development server
+3. Use a Pull Request to merge those changes to the master branch
+4. Upon approval, have someone run
+    ```
+    $ git checkout master
+    $ git pull
+    $ yarn run deploy
+    ```
+    They should then check that the deployment at https://siggraph-uiuc.github.io/siggraph looks correct.
+5. Finally, you can make a PR from the fork to the original repository
