+The section on [integer primitives](https://github.com/akkartik/mu/blob/main/mu.md#integer-primitives) shows that Mu consistently follows a few rules:
+* Instructions that write to a register always have an output before the `<-`.
+* Instructions that use an argument in memory always have it as the first
+  inout.
+* Instructions that write to memory have a preposition in their name. Contrast
+  `add` to a register vs `add-to` a memory location, `subtract` from a
+  register vs `subtract-from` a memory location, and so on.
