Installation » Composer » Adding to an existing project
If you already have a Composer project setup then run this command inside the root directory:
composer require bolt/bolt ^3.1
If you use this method you will need to bootstrap Bolt yourself, depending on when you want to dispatch requests to Bolt. For some ideas of how to set up a bootstrap file see the Creating your own Bootstrap page.
Generally most server should be fine with the default permissions. However, if you require guidance on setting up permissions, see our File System Permissions page.
After you've done this, skip to the section Setting up Bolt.
