+## Setup
+
+Clone required repositories:
+
+```bash
+laconic-so --stack fixturenet-payments setup-repositories --pull
+```
+
+Build the container images:
+
+```bash
+laconic-so --stack fixturenet-payments build-containers
+```
+
+## Deploy
+
+### Configuration
+
+Deploy the stack:
+
+```bash
+laconic-so --stack fixturenet-payments deploy --cluster payments up
+
+# Exposed on host ports:
+# 5005: go-nitro node's p2p msg port
+# 8081: reverse payment proxy's RPC endpoint
+# 15432: MobyMask v3 watcher's db endpoint
+# 3001: MobyMask v3 watcher endpoint
+# 9090: MobyMask v3 watcher relay node endpoint
+# 8080: MobyMask snap
+# 3004: MobyMask v3 app
+```
+
+Check the logs of the MobyMask contract deployment container to get the deployed contract's address and generated root invite link:
+
+```bash
+docker logs -f $(docker ps -aq --filter name="mobymask-1")
+```
+
+Check the reverse payment proxy container logs:
+
+```bash
+docker logs -f $(docker ps -aq --filter name="nitro-reverse-payment-proxy")
+```
+
+Run the ponder app:
+
+```bash
+docker exec -it payments-ponder-app-1 bash -c "pnpm start"
+```
+
+## Clean up
+
+Stop all the services running in background:
+
+```bash
+laconic-so --stack fixturenet-payments deploy --cluster payments down 30
+```
+
+Clear volumes created by this stack:
+
+```bash
+# List all relevant volumes
+docker volume ls -q --filter "name=[payments"
+
+# Remove all the listed volumes
+docker volume rm $(docker volume ls -q --filter "name=[payments")
