Docker-compose not found

I’m running docker on linux mint, and when I try to run docker-compose based on my .yml file, I get an error message saying that the docker-compose command is not found. What should I trouble-shoot?

Is docker-compose in your PATH?

$ which docker-compose

Is it executable?

$ chmod +x /usr/local/bin/docker-compose

Did you follow the installation instructions?

Thanks. I hadn’t installed it :blush:
