-## Fleet Ansible deployment
-
-Deploy MemPalace to Ezra (or the whole fleet) with the Ansible playbook:
-
-```bash
-ansible-playbook -i ansible/inventory/hosts.ini ansible/playbooks/deploy_mempalace.yml --limit ezra
-```
-
-This playbook:
-1. Creates a dedicated venv and installs `mempalace==3.0.0`
-2. Deploys `mempalace.yaml`, MCP config, and session-start hook
-3. Mines the Hermes home and sessions directories
-4. Runs a search smoke test
-5. Generates the wake-up context file
-
-Set `mempalace_run_mining=false` to skip mining on hosts where the corpus is already populated.
-
 ## Why this shape
 
 - `wing: ezra_home` matches the issue's Ezra-specific integration target.

 ## Usage
 
+### Timmy Mac wiring helper
+
+Use the dedicated Timmy helper when you want to wire a real RunPod or Vertex-style endpoint into the local Mac Hermes config:
+
+```bash
+python3 scripts/timmy_gemma4_mac.py --base-url https://your-openai-bridge.example/v1 --write-config
+python3 scripts/timmy_gemma4_mac.py --vertex-base-url https://your-vertex-bridge.example --write-config
+python3 scripts/timmy_gemma4_mac.py --pod-id <runpod-id> --write-config --verify-chat
+```
+
+The helper writes to `~/.hermes/config.yaml` by default and prints the prove-it command:
+
+```bash
+hermes chat --model gemma4 --provider big_brain
+```
