ERROR: Version in "./docker-compose.yml" is unsupported.

I got the following error while running docker compose-up

ERROR: Version in "./docker-compose.yml" is unsupported. You might be seeing this error because you're using the wrong Compose file version. Either specify a supported version (e.g "2.2" or "3.3") and place your service definitions under the `services` key, or omit the `version` key and place your service definitions at the root of the file to use version 1.
For more on the Compose file format versions, see https://docs.docker.com/compose/compose-file/

Although error is fixed, it would have been much better if README contains installation instructions and required version of docker-compose.
