-# fixturenet-payments
-
-## 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")
-```
