 * Check your logs, especially your __Web Server Log__ as well as __app/logs/partkeepr.log__
 * Only attach the parts of the logs which are __relevant__ to the problem.
-* Make sure the problem is __reproducable__. If it only happened one time, you have to find out on how to reproduce it.
-* Explain, in simple words, __when__ the issue occured. For example: Don't write "I can't create a part". Rather write: "I clicked on Add Part, entered a Part Name, then I clicked the save button, then nothing happens. There were no JavaScript errors in the console, and no HTTP Request was sent."

 The docker-compose file registers multiple container services. The main PartKeepr application is called `app`. The database is a basic configuration with `mariadb:10.1` for compatibility.

Wait for a message that the server is ready for connections and listening on port 3306. Using `<Ctrl><c>`, you can exit from the logs.
