 ### Steps for building workload image
 
+**Warning:** If any of the software versions below show as "N/A", you *must*
+fill in the correct versions. To find the missing versions (e.g., for MaxText
+commit hash, Libtpu, and Jax/Jaxlib), you may need to:
+1.  Pull the Docker image from the workload that this recipe is based on.
+2.  Start the Docker container.
+3.  Run commands within the container to get the specific versions. For example,
+to find the MaxText commit, you can use `git rev-parse HEAD` inside the cloned
+MaxText repository within the container. For Python package versions, use
+`pip show <package_name>`.
+
 The following software versions are used:
 
--   Libtpu version: 0.0.31.dev20251119+nightly
--   Jax version: 0.8.1
