+
+Instructions to setup and deploy an end-to-end L1+L2 stack with [fixturenet-eth](../fixturenet-eth/) (L1) and [Optimism](https://stack.optimism.io) (L2)
+
+## Setup
+
+Clone required repositories:
+
+```bash
+laconic-so --stack fixturenet-optimism setup-repositories
+```
+
+Checkout to the required versions and branches in repos:
+
+```bash
+# optimism
+cd ~/cerc/optimism
+git checkout @eth-optimism/sdk@0.0.0-20230329025055
+```
+
+Build the container images:
+
+```bash
+laconic-so --stack fixturenet-optimism build-containers
+```
+
+This should create the required docker images in the local image registry:
+* `cerc/go-ethereum`
+* `cerc/lighthouse`
+* `cerc/fixturenet-eth-geth`
+* `cerc/fixturenet-eth-lighthouse`
+* `cerc/foundry`
+* `cerc/optimism-contracts`
+* `cerc/optimism-l2geth`
+* `cerc/optimism-op-batcher`
+* `cerc/optimism-op-node`
+
+## Deploy
+
+Deploy the stack:
+
+```bash
+laconic-so --stack fixturenet-optimism deploy up
+```
+
+To list down the running containers:
+
+```bash
+laconic-so --stack fixturenet-optimism deploy ps
+
+# With status
+docker ps
+```
+
+## Clean up
+
+Stop all services running in the background:
+
+```bash
+laconic-so --stack fixturenet-optimism deploy down
+```
+
+Remove volumes created by this stack:
+
+```bash
+docker volume ls
+
+docker volume rm laconic-d527651bba3cb61886b36a7400bd2a38_fixturenet-geth-accounts
+docker volume rm laconic-d527651bba3cb61886b36a7400bd2a38_l1-deployment
+docker volume rm laconic-d527651bba3cb61886b36a7400bd2a38_l2-accounts
+docker volume rm laconic-d527651bba3cb61886b36a7400bd2a38_op_node_data
+```
+
+## Known Issues
+
+* Currently not supported:
+  * Stopping and restarting the stack from where it left off; currently starts fresh on a restart
+  * Pointing Optimism (L2) to external L1 endpoint to allow running only L2 services
+* Resource requirements (memory + time) for building `cerc/foundry` image are on the higher side
+  * `cerc/optimism-contracts` image is currently based on `cerc/foundry` (Optimism requires foundry installation)
