+# Setup Guide
+
+Guia passo-a-passo para clonar este projeto e ter um ambiente GitOps DevSecOps funcional na AWS.
+
+## Pré-requisitos
+
+| Ferramenta | Versão | Notas |
+|---|---|---|
+| AWS account | — | Conta paga (não Free Plan strict — t3.large não está no Free Tier) |
+| AWS CLI | 2.x | Configurado com user IAM com `AdministratorAccess` |
+| Terraform | >= 1.9.0 | |
+| Terragrunt | >= 1.0.6 | Não a versão 0.x — sintaxe mudou |
+| kubectl | >= 1.31 | |
+| Helm | >= 3.x | |
+| GitHub account | — | Com repo público ou privado |
+| GitHub PAT | fine-grained | Permissions: Actions r/w, Administration r/w sobre o repo |
+
+Custos estimados (ambientes UP):
+- 3 EKS control planes: ~$0.30/h
+- 6 nodes (2 t3.large SPOT em cada cluster): ~$0.18/h
+- ALBs/NAT/etc: ~$0.05/h
+- **Total ~$0.55/h** (~$13/dia, ~$400/mês)
+
+## 1. Fork e clone
+
+```bash
+git clone https://github.com/YOUR_GITHUB_USER/gitops-devsecops-aws
+cd gitops-devsecops-aws
+```
+
+## 2. Configurar AWS
+
+```bash
+aws configure
+# Region default sugerida: eu-central-1 (prod)
+```
+
+## 3. Bootstrap (S3 backends, DynamoDB, GitHub OIDC)
+
+```bash
+cd bootstrap
+cp terraform.tfvars.example terraform.tfvars
+# Edita terraform.tfvars e coloca o teu github_repo (formato owner/repo)
+terraform init
+terraform apply
+cd ..
+```
+
+Outputs importantes:
+- `aws_iam_role.github_actions` ARN — vai ser usado como GitHub Secret `AWS_ROLE_ARN`
+
+## 4. Deploy do cluster security (Paris, eu-west-3) — PERMANENTE
+
+```bash
+terragrunt run --all apply --working-dir environments/security --non-interactive
+```
+
+Demora ~25 min. Cria VPC + EKS + addons + IAM roles + S3 Harbor + KMS.
+
+Cria access entry (kubectl funciona):
+
+```bash
+aws eks update-kubeconfig --name security-eks --region eu-west-3 --alias security
+```
+
+## 5. Deploy do cluster prod (Frankfurt, eu-central-1) — PERMANENTE
+
+```bash
+terragrunt run --all apply --working-dir environments/prod --non-interactive
+```
+
+> Nota: o cluster `dev` (Ireland) é **ephemeral**, criado pelo workflow GitOps quando se faz merge para a branch `dev`. **Não criar manualmente**.
+
+## 6. Instalar Helm charts no security (security tools)
+
+```bash
+kubectl config use-context security

+## 7. Setup do GitHub Self-Hosted Runner (ARC)
+
+Cria um **GitHub PAT** com permissions:
+- Actions: Read and write
+- Administration: Read and write
+
+```bash
+read -s -p "Cola o GitHub PAT: " GITHUB_PAT
+kubectl create namespace actions-runner-system
+kubectl create secret generic controller-manager -n actions-runner-system \
+  --from-literal=github_token=$GITHUB_PAT
+unset GITHUB_PAT
+
+helm install actions-runner-controller actions-runner-controller/actions-runner-controller \

+
+# Editar kubernetes/manifests/security-tools/github-runner.yaml: substitui YOUR_GITHUB_USER/gitops-devsecops-aws
+kubectl apply -f kubernetes/manifests/security-tools/github-runner.yaml
+
+# Validar
+kubectl get runners -n security-tools
+```
+
+## 8. GitHub Secrets
+
+Em `Settings → Secrets and variables → Actions`, adicionar:
+
+| Secret | Valor |
+|---|---|
+| `AWS_ROLE_ARN` | ARN do `github-actions-role` criado pelo bootstrap |
+| `SONAR_TOKEN` | Token gerado no SonarQube (Profile → Security → Generate Token) |
+| `SONAR_HOST_URL` | `http://sonarqube-sonarqube.security-tools.svc.cluster.local:9000` |
+| `DEFECTDOJO_TOKEN` | API token do DefectDojo (Profile → API v2 Key → Generate) |
+| `DEFECTDOJO_URL` | `defectdojo-django.security-tools.svc.cluster.local` |
+| `SLACK_WEBHOOK` | (opcional) URL do webhook Slack para notificações |
+
+## 9. GitHub Environments
+
+Em `Settings → Environments`, criar:
+- `dev-approval` → Required reviewers: o teu user (gate para Deploy Dev)
+- `production` → Required reviewers: o teu user (gate para Deploy Prod)
+
+## 10. Branch Protection
+
+Em `Settings → Rules → Rulesets → New ruleset`:
+
+- Target: `main`
+- Require pull request before merging (1 approval)
+- Require status checks: `security-scan`, `pr-checks`
+- Require review from Code Owners
+- Block force pushes
+- Do not allow bypassing
+
+## 11. Flow GitOps em uso
+
+```text
+feature branch    →    PR para dev    →    [security-scan + pr-checks]
+                                                      ↓ approve

+                                                      ↓ approve
+                                                    merge
+                                                      ↓

+                                          ├─ destroy dev
+                                          └─ deploy prod (Frankfurt)
+```
+
+## 12. Tear down (apagar tudo)
+
+```bash
+terragrunt run --all destroy --working-dir environments/dev --non-interactive
+terragrunt run --all destroy --working-dir environments/prod --non-interactive
+terragrunt run --all destroy --working-dir environments/security --non-interactive
+
+cd bootstrap
+# Esvaziar buckets S3 antes (têm versioning)
+# ver scripts/cleanup.sh
+terraform destroy
+```
+
+## Troubleshooting
+
+### "BucketRegionError" no terragrunt
+O `root.hcl` força region `eu-central-1` no remote_state. Se mudaste isso, ajusta.
+
+### "EntityAlreadyExists" em IAM roles
+Sobras de runs anteriores. Apaga manualmente:
+```bash
+aws iam delete-role --role-name <ROLE>
+```
+
+### Workflows não disparam
+- Confirma branch protection não bloqueia a branch destino
+- Confirma o ficheiro `.github/workflows/*.yaml` está na branch que está a fazer push
+
+### Runner offline
+```bash
