Look good to me! It looks like @hermanzdosilovic wrote that part because he intends for the rest of the containers to start after the Redis is fully booted, but if the first `docker-compose up -d' starts, it will take time to download the container from the Docker Hub, so if you use depends_on, you don't need to delay the service execution speed.

yes, and them we could change this part on the changelog:

cd judge0-v1.13.0
docker-compose up -d db redis
sleep 10s
docker-compose up -d
sleep 5s

to be a simple docker-compose up -d

also, the deployment steps for a local intallation could be moved to readme, what do you think? took me a good time to find it on changelog heheh

Agree with you. We can still find it in Line 50 in README.md,

@ryankwondev its almost 2 years now, how is it? only remember about that cause got a message about a merge conflict
