Because sometimes you just don't want to deal with docker files, volume definitions, networks and docker registries. Since it's written in Go, Process Compose is a single binary file and has no other dependencies.

Once installed, you just need to describe your workflow using a simple YAML schema in a file called process-compose.yaml:

version: "0.5"

processes:
  hello:
    command: echo 'Hello World from Process Compose'

And start it by running process-compose up from your terminal.
