 ## Deploy Needle
 
-Download the folder for your platform from the release:
+The recommended install on anything that runs Python is pip; it fetches the right build for your platform automatically on first use and caches it:
+
+```sh
+pip install cactus-needle
+```
+
+That covers the whole Quickstart above, plus the `needle` CLI: `needle playground` for a local UI, `needle finetune` and `needle build` for training and exporting your own.
+
+For the standalone command-line binary or the embedded libraries (C, mobile, WebAssembly), pull your platform folder with the model config using the Hugging Face CLI instead of downloading files by hand:
+
+```sh
+pip install -U huggingface_hub
+hf download Cactus-Compute/needle2 --include "macos-arm64/*" "config.json" --local-dir needle2
+```
+
