-# railiance-bootstrap
+# Railiance Bootstrap
 
-**Railiance Bootstrap** — opinionated, reproducible IaC to rebuild Coulomb infra from scratch.
+Railiance is an opinionated **Infrastructure-as-Code framework** —  
+think *Rails for Ops*: convention over configuration, reproducibility first.
 
-## Goals
+This repo (`railiance-bootstrap`) is the **entry point**:  
-- Two Linux machines + this Git repo + credentials ⇒ full rebuild
+from two bare Linux servers, a Git repo, and credentials, you can rebuild  
-- GitOps-first with ArgoCD/Flux
+a fully automated Kubernetes-based environment.
-- OODA (Observe→Orient→Decide→Act) encoded as pipelines
-- Tests define success at every step

+## 🚀 Quick Start
-helm/     # charts & values

-k8s/      # raw manifests/CRDs
+1. **Clone this repo**
-tests/    # expectation tests (bash/py)
+   ```bash
-docs/     # operator notes, OODA SOPs
+   git clone <your-gitea-url>/railiance-bootstrap.git
-```
+   cd railiance-bootstrap
+   ```
+
+2. **Configure Gitea access**  
+   Edit `~/.railiance_gitea.conf` with your server URL, username, and token.  
+   *(Never commit this file!)*
+
+3. **Bootstrap a host**  
+   Run the Ansible playbooks in `ansible/` to set up k3s, Helm, kubectl.  
+
+4. **Deploy baseline services**  
+   Use `helm/` charts to roll out essential services (GitOps, monitoring, etc.).  
+
+5. **Validate**  
+   Check the automated tests in `tests/` to confirm infra health.
