+## Intent
+Allows to encode behaviour as instructions for virtual machine.
+
+## Applicability
+Use the Bytecode pattern when you have a lot of behavior you need to define and your
+game’s implementation language isn’t a good fit because:
+
+* it’s too low-level, making it tedious or error-prone to program in.
+* iterating on it takes too long due to slow compile times or other tooling issues.
+* it has too much trust. If you want to ensure the behavior being defined can’t break the game, you need to sandbox it from the rest of the codebase.
