# devenv Setup

Get a project's tools and services running the same way everywhere

## What this does

Getting a project running usually means installing the right languages, packages and background services by hand, and hoping your machine matches everyone else's. This writes and configures the devenv file that describes that setup instead. Reach for it when starting a new project or adding something to an existing environment.

### Top 3 things it does for you

- Set up a devenv environment for a project
- Add a language or a package to it
- Wire up a service the project needs
