When to use inline backticks in documentation

Question

When writing documentation, what things should be put in inline backticks?

For example I use inline backticks for the following,

• commands
  • E.g. "To run the program, run python3 helloworld.py"
• example output
  • E.g. "python3 helloworld.py should return hello world"
• specific kubernetes resources
  • E.g. "Every pod except cache-deployer should be running"

However, should I also use it for e.g. group membership?

• E.g. "User must be member of leet_users"

How do I do this consistently?
