+# Pi AI Harness
+
+## Prereqs
+
+I would recommend using `pass` to store your api key. This is installed with `dnf install pass` on Fedora systems.
+
+After installing pass, update your `~/.gnupg/gpg-agent.conf` to set the timeout to max so automated processes can use the values in your password store:
+
+```conf
+default-cache-ttl 2147483647
+max-cache-ttl 2147483647
+```
+
+Then add a `pass.sh` to you `~/.bashrc.d` that looks like
+
+```bash
+pass unlock
+```
+
+That way every time you log in your pass keyring is unlocked for your session so automations can use it.
+
+## Setup
+
+This is my ~/.pi/agent/models.json
+
+```json
+{
+  "providers": {
+    "reeseapps-aipi": {
+      "baseUrl": "https://aipi.reeseapps.com/v1",
+      "api": "openai-completions",
+      "apiKey": "!pass aipi/dev-token",
