+Instructions for deploying a local a geth + lighthouse blockchain "fixturenet" for development and testing purposes using laconic-stack-orchestrator (the installation of which is covered [here](https://git.vdb.to/cerc-io/stack-orchestrator)):
+
+## Clone required repositories
+
+```
+$ laconic-so --stack fixturenet-eth setup-repositories
+```
+
+## Build the fixturenet-eth containers
+
+```
+$ laconic-so --stack fixturenet-eth build-containers
+```
+
+This should create several container images in the local image registry:
+
+* cerc/go-ethereum
+* cerc/lighthouse
+* cerc/fixturenet-eth-geth
+* cerc/fixturenet-eth-lighthouse
+
+## Deploy the stack
+
+```
+$ laconic-so --stack fixturenet-eth deploy up
+```
+
+## Check status
+
+```
+$ laconic-so --stack fixturenet-eth deploy exec fixturenet-eth-bootnode-lighthouse /scripts/status-internal.sh
+Waiting for geth to generate DAG.... done
+Waiting for beacon phase0.... done
+Waiting for beacon altair.... done

+
+## Additional pieces
+
+Several other containers can used with the basic `fixturenet-eth`:
+
+* `ipld-eth-db` (enables statediffing)
+* `ipld-eth-server` (GQL and Ethereum API server, requires `ipld-eth-db`)
+* `ipld-eth-beacon-db` and `ipld-eth-beacon-indexer` (for indexing Beacon chain blocks)
+* `eth-probe` (captures eth1 tx gossip)
+* `keycloak` (nginx proxy with keycloak auth for API authentication)
+* `tx-spammer` (generates and sends automated transactions to the fixturenet)
+
+It is not necessary to use them all at once, but a complete example follows:
+
+```
+# Setup
+$ laconic-so setup-repositories --include git.vdb.to/cerc-io/go-ethereum,git.vdb.to/cerc-io/ipld-eth-db,git.vdb.to/cerc-io/ipld-eth-server,github.com/cerc-io/ipld-eth-beacon-db,github.com/cerc-io/ipld-eth-beacon-indexer,github.com/cerc-io/eth-probe,git.vdb.to/cerc-io/tx-spammer
+
