 * Ensure your code is nicely formatted in the [PSR-2](https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md)
 style and that all tests pass.
 * Send the pull request.
-* Check that the Travis CI build passed. If not, rinse and repeat. **Note:** This repo uses [Psalm](https://github.com/vimeo/psalm) to statically analyze all the code. Psalm runs on all the builds for PHP 5.5+.
-
-**NOTE:** This repo requires pull-request reviews for all changes on branches bound for production in accordance with Vimeo policy.
 
 ## Testing locally
 To install Psalm and run the full test suite locally, download [Composer](https://getcomposer.org/) into the repository and then run:
 
 ```
-make install
-make
-```
-
-If you use PHP 5.3 or 5.4 locally (which are not supported by the latest version of Psalm), you can skip Psalm by running:
-
-```
-make install_no_psalm
-make no_psalm
+make test
 ```
