+Deploy a stack for demoing Nitro-based auth, using either a local fixturenet (fully self-contained) or remote testnet.
+
+## Local Fixturenet (Self-Contained)
+
+### Clone required repositories
+
+```
+$ laconic-so --stack fixturenet-eth setup-repositories
+$ laconic-so --stack go-nitro-auth setup-repositories
+```
+
+### Build containers
+
+```
+$ laconic-so --stack fixturenet-eth build-containers
+$ laconic-so --stack go-nitro-auth build-containers
+```
+
+### Create a deployment
+
+```
+$ laconic-so --stack fixturenet-eth deploy init --output nitro-net.yml
+$ laconic-so --stack fixturenet-eth deploy create --spec-file nitro-net.yml --deployment-dir /srv/nitro-net
+
+$ laconic-so --stack go-nitro-auth deploy init --map-ports-to-host any-same --output nitro-auth.yml
+$ laconic-so --stack go-nitro-auth deploy create --spec-file nitro-auth.yml --deployment-dir /srv/nitro-auth
+
+# Place them both in the same namespace (TODO: support setting the deployment name via --cluster).
+$ cp /srv/nitro-net/deployment.yml /srv/nitro-auth/deployment.yml
+```
+
+### Start the containers
+
+```
+$ laconic-so deployment --dir /srv/nitro-net up
+$ laconic-so deployment --dir /srv/nitro-auth up
+```
+
+### Open the webapp
+
+Visit http://localhost:5678
+
+## Remote Testnet
+
+This example will use the Linea Sepolia testnet.
+
+### Clone required repositories
+
+```
