+# docker-stacks-update
+
+Finds all running Docker Compose stacks, pulls the latest images, and
+restarts only the stacks that received updates.
+
+## Requirements
+
+- **docker** (with Compose v2 plugin — `docker compose`, not `docker-compose`)
+- **jq** — used to parse the JSON output of `docker compose ls`
+
+## Installation
+
+Place the script anywhere in your `$PATH`, for example:
+
+```bash
+cp docker-stacks-update ~/.local/bin/
+chmod +x ~/.local/bin/docker-stacks-update
+```
+
+## Usage
+
+```bash
+docker-stacks-update
+```
+
+Run from any directory — the script finds every running stack
+system-wide using `docker compose ls`.
+
+## What it does
+
+1. **Discover** — lists all running stacks with `docker compose ls
+   --format json`
+2. **Pull** — runs `docker compose pull` for each stack
+3. **Detect** — checks whether any service image was actually
+   downloaded (not just "already up to date")
+4. **Restart** — recreates containers with `docker compose up -d` only
+   for stacks that received new images
+5. **Orphan cleanup** — any stack whose compose file(s) no longer exist
+   on disk is torn down automatically
+6. **Report** — prints a summary showing updated (with service names),
+   unchanged, orphaned (removed), and failed stacks
