-## 🚀 Why Sovereign Infrastructure?
+## What is this repo?
-Every SaaS you pay for is a piece of your sovereign control you are leasing. The mission of **AltStack** is to provide the data and deployment configurations necessary to replace the "Big Tech" stack with a **Sovereign Stack** you own.
+This is the **data layer** for [The AltStack](https://thealtstack.com) — a curated directory of open-source alternatives to popular SaaS products. Everything the website displays comes from the files in this repo:
-This repository serves as the **Data HQ** for [The AltStack](https://thealtstack.com). Every tool listed here is vetted for quality, activity, and self-hostability. See [CRITERIA.md](CRITERIA.md) for the full vetting standards.
+- The full tool database (`tools.json`)
+- Docker Compose deployment configs for 68+ tools
+- Blog content and editorial copy
+- Category descriptions and SEO metadata
+- Curated "Stack" bundles (pre-built tool combos for common use cases)
-## 🚀 Quick Start (Mini-Stacks)
+If you want to add a tool, fix a description, or contribute a Docker config — this is where you do it.
-Get up and running in under 2 minutes. These are "Development Mode" snippets. For production-hardened setups (SSL, Backups, Auth), follow the links to The AltStack Documentation.

-## ⚡ Quick Start: Deploy Your First Alternative
-
-Most tools in this list can be deployed in minutes using Docker. Here is how to get started with the AltStack approach:
-
-1. **Clone this repo**: `git clone https://github.com/altstackHQ/altstack-data.git`
-2. **Explore `/deployments`**: Find the Docker Compose file for the tool you want.
-3. **Go Sovereign**: Visit [docs.thealtstack.com](https://docs.thealtstack.com) for production-hardened guides (SSL, backups, and reverse proxies).
-
-> [!TIP]
-> This repository contains basic community configs. For commercial-grade Sovereign Infrastructure setup, always refer to our [Official Documentation](https://docs.thealtstack.com).
+Every config in `docker-deploy/` is a ready-to-use `docker-compose.yml` with an accompanying `install.sh` script. Just clone and run:
```bash
-cd deployments/plausible
-docker-compose up -d
+cd docker-deploy/plausible
+chmod +x install.sh
+./install.sh
+```
+
+Or copy the `docker-compose.yml` directly:
+
+```bash
+cd docker-deploy/n8n
+docker compose up -d
+```
+
+Currently covering **68 tools** including: Supabase, Mattermost, Plausible, PostHog, Keycloak, N8N, Immich, Authentik, Metabase, Plane, and many more.
+
+> **Want to add a config?** See [CONTRIBUTING.md](CONTRIBUTING.md). We test every config before merging.

+## How the Data Stays Fresh
+
+This repo is kept up-to-date by an automated pipeline (the "Sentinel Engine") that runs nightly via GitHub Actions:
+
+1. **Discovery** — Scans GitHub trending, Hacker News, and community submissions for new tools
+2. **Validation** — Checks existing entries for dead links, archived repos, and stale projects
+3. **Enrichment** — Pulls latest GitHub stars, activity metrics, and metadata
+4. **Docker generation** — Auto-generates Docker Compose configs for newly added tools
+5. **Content** — Generates blog posts, tool reviews, and comparison pages
+
+The pipeline opens PRs automatically so everything gets reviewed before merging.
