 # Continuous Deployment
 
-The cryodev infrastructure uses two deployment strategies optimized for different host types.
+All hosts use **Comin** (pull-based) for automatic deployment.
 
 ## Overview
 
 | Host | Strategy | Tool | Trigger |

-| `cryodev-main` | Push-based | deploy-rs | Git push via Forgejo Actions |
-| `cryodev-pi` | Pull-based | Comin | Periodic polling |

-## Push-based Deployment (cryodev-main)
-
-### How It Works
+## How It Works
 
 1. Developer pushes to `main` branch
-2. Forgejo Actions workflow triggers
-3. `deploy-rs` connects via SSH and deploys
+2. CI (Forgejo Actions) runs flake-check and builds all hosts
+3. Comin on each host periodically polls the Git repository
+4. On changes, Comin builds and activates the new configuration
 
-### Setup
-
-#### 1. Generate Deploy Key
-
-```bash
-ssh-keygen -t ed25519 -f deploy_key -C "forgejo-actions"
-```
-
-#### 2. Add Public Key to Server
-
-On `cryodev-main`:
-
-```bash
-echo "PUBLIC_KEY_CONTENT" >> /root/.ssh/authorized_keys
-```
-
-#### 3. Add Private Key to Forgejo
-
-1. Go to Repository Settings > Secrets
-2. Add secret named `DEPLOY_SSH_KEY`
-3. Paste the private key content
-
-#### 4. Workflow Configuration
-
-`.forgejo/workflows/deploy.yaml`:
-
-```yaml
-name: Deploy
-on:
-  push:
-    branches: [main]
-
-jobs:
-  check:
-    runs-on: ubuntu-latest
-    steps:
-      - uses: actions/checkout@v4
-      - uses: cachix/install-nix-action@v24
-      - run: nix flake check
-
-  deploy:
-    needs: check
-    runs-on: ubuntu-latest
-    steps:
-      - uses: actions/checkout@v4
-      - uses: cachix/install-nix-action@v24
-      
-      - name: Setup SSH
-        env:
-          SSH_PRIVATE_KEY: ${{ secrets.DEPLOY_SSH_KEY }}
-        run: |
-          mkdir -p ~/.ssh
-          echo "$SSH_PRIVATE_KEY" > ~/.ssh/id_ed25519
-          chmod 600 ~/.ssh/id_ed25519
-          ssh-keyscan cryodev-main >> ~/.ssh/known_hosts
-          
-      - name: Deploy
-        run: nix run github:serokell/deploy-rs -- .#cryodev-main
-```
-
-### Rollback
-
-deploy-rs automatically rolls back if the new configuration fails health checks.
-
-Manual rollback:
-
-```bash
-# List generations
-sudo nix-env -p /nix/var/nix/profiles/system --list-generations
-
-# Rollback to previous
-sudo nixos-rebuild switch --rollback
-```
-
-## Pull-based Deployment (cryodev-pi)
-
-### How It Works
-
-1. Comin periodically polls the Git repository
-2. On changes, it builds and activates the new configuration
-3. Works through NAT without incoming connections
-
