Say i installed redis and use it locally. Will it be automatically installed during trellis provisioning?

Another question, will trellis always provision the server before deploying for each deploy attempt?

A run down of trellis deployment will be helpful.

Our [docs](https://roots.io/trellis/docs/remote-server-setup/) detail the difference between provisioning and deployment. And there’s a section on [Deploys](https://roots.io/trellis/docs/deploys/) as well.

Any new software (like Redis), will only be installed if its added to a role and that role is called from a playbook. Example: [memcached role](https://github.com/roots/trellis/tree/master/roles/memcached).

Roles, playbook and other terms are quite new to me. Apparently i will have to get acquainted with ansible.

Any recommend reading i peruse to get up to speed with Trellis?

The good thing about Trellis is its just Ansible. And there’s a lot of Ansible documentation and tutorials. Their official docs are quite good: [http://docs.ansible.com/](http://docs.ansible.com/)

[https://sysadmincasts.com/](https://sysadmincasts.com/) has a bunch of good Ansible related screencasts too. Those first ~5 ones listed are all useful for using Trellis.
