+
+## Continuous IMAP Mailbox Sync in a Single Container
+
+dockerized-imap-sync is a standalone Docker container that runs `imapsync` on a 3-minute cron schedule to continuously mirror one IMAP mailbox to another. It reproduces the behavior of a Kubernetes `CronJob` without requiring a cluster — just a single `docker run`.
+
+## Why It Exists
+- Drop-in replacement for the `imap-cron.yml` Kubernetes CronJob for environments that don't have a cluster.
+- Fully self-contained: no external scheduler, no orchestrator dependency.
+- Environment-variable-driven — swap source or destination without rebuilding the image.
+
+## Configuration
+
+All credentials are passed as runtime environment variables:
+
+| Variable | Description |
+|---|---|
+| `IMAP1_HOST` | Source IMAP server (default: `imap.mail.yahoo.com`) |
+| `IMAP1_USER` | Source mailbox username |
+| `IMAP1_PASSWORD` | Source mailbox password |
+| `IMAP2_HOST` | Destination IMAP server (default: `imap.gmail.com`) |
+| `IMAP2_USER` | Destination mailbox username |
+| `IMAP2_PASSWORD` | Destination mailbox password |
+
+Defaults are baked in for Yahoo and Gmail hosts, but all variables should be passed explicitly at runtime.
+
+## Usage
+
+```bash
+docker run -d \
+  --name dockerized-imap-sync \
+  -e IMAP1_HOST='imap.mail.yahoo.com' \
+  -e IMAP1_USER='your-source-user' \
+  -e IMAP1_PASSWORD='your-source-password' \
+  -e IMAP2_HOST='imap.gmail.com' \
+  -e IMAP2_USER='your-destination-user' \
+  -e IMAP2_PASSWORD='your-destination-password' \
+  dockerized-imap-sync
+```
+
+## Behavior
+- `imapsync` runs every 3 minutes via an internal cron job
+- Fails fast if any required environment variable is missing at startup
+- Sync flags mirror the original Kubernetes job exactly for behavioral parity
+
+## CI/CD
+
+The repository includes a GitHub Actions workflow that builds and pushes the image to GHCR on every push to `main` and on manual dispatch.
+
+Published tags:
+- `ghcr.io/<owner>/dockerized-imap-sync:latest`
+- `ghcr.io/<owner>/dockerized-imap-sync:sha-<commit>`
+
+## Status
+- **State:** Active, publicly available.
+- **Role:** Full design and implementation (container, cron setup, CI/CD pipeline).
