+# Installation
+
+## Prerequisites
+
+- [Rust](https://rustup.rs/) 1.93.1+
+- [Docker](https://docs.docker.com/get-docker/)
+- A [Vultr](https://www.vultr.com/) account
+- A [Cloudflare](https://www.cloudflare.com/) account (for DNS, CDN, and Origin certificates)
+- An S3-compatible bucket for Terraform state (e.g. Cloudflare R2)
+
+## Local Development
+
+```bash
+cp .env.example .env
+mkdir -p data
+curl -fsSL -o data/Merged-IP.mmdb \
+  "https://github.com/NetworkCats/Merged-IP-Data/releases/latest/download/Merged-IP.mmdb"
+cargo run
+```
+
+The server starts at `http://localhost:3000` by default.
+
+For the full local stack with HAProxy and TLS termination:
+
+```bash
+docker compose up --build
+```
+
+## Automated Deployment via GitHub Actions
+
+Pushing a version tag (e.g. `v1.0.0`) triggers the full deployment pipeline:
+
+```
+v* tag push --> CI checks --> Docker build + push to GHCR --> Terraform + Ansible deploy
+```
+
+### Pipeline Overview
+
+1. **Check** -- Runs `cargo fmt`, `cargo clippy`, and `cargo test`.
+2. **Build** -- Builds a Docker image and pushes it to GitHub Container Registry (`ghcr.io`).
+3. **Deploy** -- Provisions infrastructure with Terraform and configures/deploys with Ansible.
+
+The deploy job uses a `production` environment with concurrency control to prevent overlapping deployments.
+
+### Required GitHub Secrets
+
+Go to **Settings > Secrets and variables > Actions** in your GitHub repository and add the following secrets.
+
+If you are using environments, add them under the `production` environment (**Settings > Environments > production**).
+
+#### Terraform State (S3-compatible backend)
+
+| Secret | Description |
+|---|---|
+| `TF_STATE_ACCESS_KEY` | Access key for the S3-compatible state backend (e.g. Cloudflare R2) |
+| `TF_STATE_SECRET_KEY` | Secret key for the S3-compatible state backend |
+| `TF_STATE_BUCKET` | Bucket name where Terraform state is stored |
+| `TF_STATE_ENDPOINT` | S3-compatible endpoint URL (e.g. `https://<account_id>.r2.cloudflarestorage.com`) |
+
+#### Infrastructure
+
+| Secret | Description |
+|---|---|
+| `VULTR_API_KEY` | Vultr API key for provisioning VPS and firewall resources |
+| `SSH_PUBLIC_KEY` | Public key deployed to the VPS for SSH access |
+| `SSH_PRIVATE_KEY` | Corresponding private key used by the pipeline to connect via SSH |
+
+#### Application
+
+| Secret | Description |
+|---|---|
+| `SITE_DOMAIN` | Production domain name (e.g. `ip.nc.gy`) |
+| `DB_UPDATE_URL` | URL to download the MMDB database from |
+
+#### TLS
+
+| Secret | Description |
+|---|---|
+| `ORIGIN_CERT` | Cloudflare Origin certificate (PEM) for TLS termination at HAProxy |
+| `ORIGIN_KEY` | Corresponding private key (PEM) for the Origin certificate |
+
+`GITHUB_TOKEN` is provided automatically by GitHub Actions and does not need to be configured. It is used to authenticate with GHCR.
+
+### Deploying
+
+```bash
+git tag v1.0.0
+git push origin v1.0.0
+```
+
+This triggers the full pipeline. Monitor progress under the **Actions** tab in the repository.
+
+### Infrastructure Details
+
+- **VPS**: Vultr High Frequency (`vhf-2c-2gb`), Debian 13, region `dfw` (Dallas)
+- **Firewall**: SSH open, HTTPS restricted to Cloudflare IP ranges
+- **Deployment**: Blue-green with HAProxy traffic switching
+- **First deploy**: Automatically applies base OS hardening (UFW, fail2ban, sysctl tuning) and installs Docker
+- **Subsequent deploys**: Only the application container is updated via blue-green swap
