 ## Project Structure
 - `bot.js` — Core logic: login to X, generate tweet via Claude, post it
 - `scheduler.js` — Picks random times within a window, invokes bot.js via child_process
+- `cron.js` — Docker entrypoint: writes prompts.json from env, fires scheduler.js daily at 4pm UTC
+- `Dockerfile` — Node 18 alpine image
 - `package.json` — Dependencies & scripts
-- `.env` — Credentials (not tracked)
 - `prompts.json` — Prompt configs with account mapping, schedule, and link placeholders (not tracked)
-- `history-<prompt-name>.json` — Per-prompt tweet history (auto-generated)
+- `infra/docker-compose.yml` — One service per prompt, named volume for history files
+- `infra/deploy-stack.sh` — Deploys stack to Portainer (run once, or on compose changes)
+- `infra/.env` — All secrets + PROMPTS_JSON (not tracked)
+- `infra/.env.example` — Template
 
 ## Entry Points
-- `node bot.js <prompt-name>` — Post a single tweet immediately
-- `node scheduler.js <prompt-name>` — Schedule random posts for the day
+- `node bot.js <prompt-name>` — Post a single tweet immediately (local dev)

 ## Deployment
-Deployed on AWS EC2 in **us-west-2**:
-- Instance: `i-088b711cac69e6ac9`
-- Name: `xbot`
-- Type: `t4g.nano` (ARM-based)
-- Public IP: `44.249.48.3`
-- AWS account: `457667483187`
-- Cron: `0 16 * * *` (4pm UTC / before 8am PST window), one job per prompt
+Deployed on **docker-server** (Portainer):
+- Portainer: `https://portainer-1.docker.pq.io`
+- Registry: `registry.docker.pq.io`
+- Stack: `xbot`
+- Containers: `xbot-<account>-<prompt>` (e.g. `xbot-thejunipersky-tease`)
+- Scheduling: `cron.js` fires at 4pm UTC daily — no host cron needed

+### To redeploy after code changes
+1. Boot a t3.micro x86 build machine in AWS us-west-2 (key: `twitter-bot-key`, SG: `sg-088158905150b9051`, subnet: `subnet-08fe6b8d1dc82f243`)
+2. Build and push: `docker build --platform linux/amd64 -t registry.docker.pq.io/xbot:latest . && docker push registry.docker.pq.io/xbot:latest`
+3. Watchtower auto-restarts containers within 30s
+4. Terminate build machine
+
+### To redeploy after compose/config changes
+Run `infra/deploy-stack.sh` with `PORTAINER_URL` and `PORTAINER_API_KEY` set.
 
 ## Guidelines
 - All changes must preserve stealth/anti-detection behavior and multi-account architecture
