+# go-nitro-auth
+
+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
+
+```
+$ laconic-so --stack go-nitro-auth setup-repositories
+```
+
+### Build containers
+
+```
+$ laconic-so --stack go-nitro-auth build-containers
+```
+
+### Create a deployment
+
+```
+$ 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
+```
+
+### Set your keys, contract addresses, etc.
+
+You must set the private keys for two accounts with funds on the target network, as well as the contract addresses
+(if they already exist) or else an account to create them.  You must also set the URL to use for WebSocket connections,
+eg, `wss://linea-sepolia.infura.io/ws/v3/<MY_API_KEY>`
+
+#### Config
+
+```
+$ vim /srv/nitro-auth/config.env
+# Addresses of existing contracts.
+CERC_CA_ADDRESS="0x1Ae815c3e7556e16ceaB6B6d46306C1870EB6d24"
+CERC_NA_ADDRESS="0xc453C5E3f304bb545A3Df7bBa02fe6274A056636"
+CERC_VPA_ADDRESS="0xA11af80D75b1150631FA78178c94fa451c7172a8"
+
+# Else the private key of an account and RPC URL to use create them.
+CERC_PRIVATE_KEY_DEPLOYER=<PRIV_KEY_HERE>
+CERC_ETH_RPC_ENDPOINT=https://rpc.sepolia.linea.build
+
+# The WebSocket chain URL.
+CERC_NITRO_CHAIN_URL=wss://linea-sepolia.infura.io/ws/v3/<MY_API_KEY_HERE>
+
+# Private key for "Alice" account (payer)
+CERC_NITRO_CHAIN_PK_ALICE=<ALICE_PRIVATE_KEY_HERE>
+
+# Private key for "Bob" account (payee)
+CERC_NITRO_CHAIN_PK_BOB=<BOB_PRIVATE_KEY_HERE>
+```
+
+### Start the stack
+```
+$ laconic-so deployment --dir /srv/nitro-auth up
+```
