+# Docker Compose config collection
+
+## How to set up?
+
+Basically you need to choose which service you want to run and then
+create needed `.env` files from `.end.dist` template.
+
+```shell
+# Choose a service
+cd folding-at-home
+# Copy template
+cp .env.dist .env
+# edit the config to your preference
+nano -w .env
+# Create and run containers
+docker-compose up -d
+# Optional: check the logs
+docker-compose logs -f
+```
+
+Some services may require additional configuration. Check for additional `README.md` files
+or comments in the `docker-compose.yml` files or `.env.dist` templates.
