When writing your CloudFormation yaml:

• Don't use Default values on Parameter. This is because making a change to just the Default value of a parameter is not considered by CloudFormation in it's difference analysis. Once the value has been set it stays set.
• Use !Ref parameterName instead of !Sub '${parameterName}'
• Don't pollute the cloudformation.yaml with notions of non-prod and prod modes. Pass one application parameter in with names like myapp-dev, myapp-test and use ${application} to build your resource names.
• When you create buckets use a suffix with the lower-case (an S3 constraint) account id. This is so you can deploy your cloudformation.yaml to any account without conflicts.
• Never use that Fn:Join nonsense. Use !Sub instead. For example:

!Sub "arn:aws:secretsmanager:${AWS::Region}:${AWS::AccountId}:secret:${mySecretName}-*

With markdown table with extra Notes column we get pretty horrendous Notes column size (small) as the screen width lowers. Once you get to mobile it's very yuk. In fact the dominant column in terms of size is determined by the longest text in a cell so if a long note gets put in then that will make the Notes column dominate sizing:

ID	Rule	Notes
1	A Subscriber MUST signal demand via Subscription.request(long n) to receive onNext signals.	It is intended blah blah that something happens here that is not confusing and stuff
2	If a Subscriber suspects that its processing of signals w
