+(Work in progress)

+* Don't try to replace every tool. Instead, be an ingredient to improve them.
+* When hesitating between 2 options, choose the one that is easier to reverse.
+* No is temporary, Yes is forever. If you're not sure about a new feature, say no. You can change your mind later.
+* Containers must be portable to the greatest possible number of machines. Be suspicious of any change which makes machines less interchangeable.
+* The less moving parts in a container, the better.
+* Don't merge it unless you document it.
+* Don't document it unless you can keep it up-to-date.
+* Don't merge it unless you test it!
+* Everyone's problem is slightly different. Focus on the part that is the same for everyone, and solve that.
