 # Internal Build Notes / IRD
 
 - When building the runtime we must use Ubuntu 20.04 docker image
+  - When making an IRD reservation use `--docker-image
+    yyz-gitlab.local.tenstorrent.com:5005/tenstorrent/infra/ird-ubuntu-20-04-amd64:latest`
 - You'll have to manaully install a newer version of cmake, at least 3.20, the easiest way to do this is to `pip install cmake` and make sure this one is in your path
 - You'll want LLVM installation to persist IRD reservations, you can achieve this by:
   - mkdir /localdev/$USER/ttmlir-toolchain

+- `mlir`: On the compiler side, we use the MLIR namespace for all MLIR types and operations and subnamespace for our dialects.
