+### Diffing
 
+[objdiff](https://github.com/encounter/objdiff) will be your primary diffing tool. You can fetch a binary from the latest GitHub Actions build, or build from source with `cargo run --release`.
+
+objdiff configuration:
+- Project dir: `prime`
+- Target build dir: `prime/build/mp1.0/asm`
+- Base build dir: `prime/build/mp1.0/src`
+- Obj: Whatever .o you're currently working on (can select from asm or src build dirs)
+- [x] Build target
+- [x] Reverse function order (deferred)
+
+objdiff will automatically rebuild and reload the object on source changes, so you can quickly iterate on functions.
+
+With CodeWarrior, the `-inline deferred` flag reverses the function order in a translation unit. You'll work bottom-up in most asm files. Dolphin SDK files do **not** use `-inline deferred`, so their function order is top-down.
+
+### Sharing
 When you have a function mismatch that you want help on, you can upload a scratch to [decomp.me](https://decomp.me):
 - Use `tools/decompctx.py src/path/to/file.cpp` to generate `ctx.c` which you can put in the "Context" field.
 - Set preset to `Metroid Prime (USA)`.
