 ## Dependencies
-Only `docker` and `docker-compose` are required. For the most part your understanding of the technologies can be superficial. So long as you can follow commands and are open to reading a bit, you should be fine.

 ### Get the docker-compose.yml file
 
 Now you can either navigate to the [docker-compose.yml](https://raw.githubusercontent.com/stashapp/stash/develop/docker/production/docker-compose.yml) in the repository, or if you have curl, you can make your Linux console do it for you:

 Once you have that file where you want it, modify the settings as you please, and then run:

 ### Docker
 Docker is effectively a cross-platform software package repository. It allows you to ship an entire environment in what's referred to as a container. Containers are intended to hold everything that is needed to run an application from one place to another, making it easy for everyone along the way to reproduce the environment.
 
-The StashApp docker container ships with everything you need to automatically build and run stash, including ffmpeg.

-Docker Compose lets you specify how and where to run your containers, and to manage their environment. The docker-compose.yml file in this folder gets you a fully working instance of StashApp exactly as you would need it to have a reasonable instance for testing / developing on. If you are deploying a live instance for production, a reverse proxy (such as NGINX or Traefik) is recommended, but not required.
