+# ERC721 Watcher
+
+Instructions to deploy a local ERC721 watcher stack (core + watcher) for demonstration and testing purposes using [laconic-stack-orchestrator](../../README.md#setup)
+
+## Setup
+
+* Clone / pull required repositories:
+
+  ```bash
+  $ laconic-so setup-repositories --include cerc-io/go-ethereum,cerc-io/ipld-eth-db,cerc-io/ipld-eth-server,cerc-io/watcher-ts --pull
+  ```
+
+* Build the core and watcher container images:
+
+  ```bash
+  $ laconic-so build-containers --include cerc/go-ethereum,cerc/go-ethereum-foundry,cerc/ipld-eth-db,cerc/ipld-eth-server,cerc/watcher-erc721
+  ```
+
+  This should create the required docker images in the local image registry.
+
+* Deploy the stack:
+
+  ```bash
+  $ laconic-so deploy-system --include db,go-ethereum-foundry,ipld-eth-server,watcher-erc721 up
+  ```
+
