 ## CPU Arch
 The CPU renderers may be additionally configured using the arch component of [the `DEV` environment variable](env_vars.md#dev-variable).
 CPU arch should be specified as a comma-separated list of parameters, and must contain at least two values: the architecture family (ie. x86_64, arm64, or riscv64) and the cpu type (as accepted by `clang`'s `-march`).
-If native is specified as the cpu type, tinygrad (or delegate compiler) will query the host cpu type. Additional comma-separated values may be specified as follows:
-
-* `AMX`: emit Apple silicon AMX instructions
-
-All other additional values are interpreted as cpu feature flags. When a value is preceded by a `-` character, the corresponding feature flag will be disabled, otherwise the flag will be enabled.

+
+This problem uses BERT for NLP.
+
+## Requirements
+
+Install tinygrad and mlperf-logging (uncomment mlperf from setup.py) from branch mlperf_training_v5.0.
+```
+git clone https://github.com/tinygrad/tinygrad.git
+python3 -m pip install -e ".[mlperf]"
+```
+Also install gdown (for dataset), numpy, tqdm and tensorflow.
+```
+pip install gdown numpy tqdm tensorflow
+```
+
+### tinybox_green
+Install the p2p driver per [README](https://github.com/tinygrad/open-gpu-kernel-modules/blob/550.54.15-p2p/README.md)
+This is the default on production tinybox green.
+
+# 2. Directions
+
+## Steps to download and verify data
+
+### 1. Download raw data
+
+```
+BASEDIR="/raid/datasets/wiki" WIKI_TRAIN=1 VERIFY_CHECKSUM=1 python3 extra/datasets/wikipedia_download.py
+```
+
