+## Contribute
+
+#### Setup
+
+```
+git clone https://github.com/genealogysystems/gen-search.git
+cd gen-search
+npm install
+```
+
+#### Add a site
+
+1. Create the site file in the [src/sites](https://github.com/genealogysystems/gen-search/tree/master/src/sites) directory. Look at [archives.js](https://github.com/genealogysystems/gen-search/blob/master/src/sites/archives.js) for a simple example or [familysearch.js](https://github.com/genealogysystems/gen-search/blob/master/src/sites/familysearch.js) for a more complex example.
+2. Add the new site to the [src/search.js] site list, in alphabetical order please.
+3. Add a test file in the [test/sites](https://github.com/genealogysystems/gen-search/tree/master/test/sites) directory. Look at any of the other site test files for an example.
+4. Run tests with `npm test`. The `gensearch.js` file will be automatically built with [browserify](https://github.com/substack/node-browserify) before the tests are run.
+5. Document the new site in the README file, in alphabetical order please. Be sure to add a link in the site list just before the site specific docs.
+6. Commit and submit a pull request.
