 Instructions for running a BSC node
 
-## Prerequisite
+## Setup
 
-Downloaded chain snapshot
+* (Optional) Download the snapshot for BSC network (mainetn | testnet) by following instructions from <https://github.com/bnb-chain/bsc-snapshots>
 
-<!-- TODO -->
+* Clone the stack repo:
+
+  ```bash
+  laconic-so fetch-stack git.vdb.to/cerc-io/bsc-stack
+  ```
+
+* Build the container images:
+
+  ```bash
+  laconic-so --stack ~/cerc/bsc-stack/stack-orchestrator/stacks/bsc-node build-containers
+  ```
+
+## Create a deployment
+
+* Create a spec file for the deployment:
+
+  ```bash
+  laconic-so --stack ~/cerc/bsc-stack/stack-orchestrator/stacks/bsc-node deploy init --map-ports-to-host any-same --output bsc-node-spec.yml
+  ```
+
+* Edit `network` in the spec file to map container ports to host ports as required
+
+* Create a deployment directory from the spec file:
+
+  ```bash
+  laconic-so --stack ~/cerc/bsc-stack/stack-orchestrator/stacks/bsc-node deploy create --spec-file bsc-node-spec.yml --deployment-dir bsc-node-deployment
+  ```
+
+* (Optional) Copy over the snapshot file (`*.tar.lz4`) in snapshot data directory in the deployment (`bsc-node-deployment/data/snapshot`):
+
+  ```bash
+  # Example
+  cp geth-pbss-pebble-20240514.tar.lz4 bsc-node-deployment/data/snapshot/
+  ```
+
+## Configuration
+
+* Environment variables for Lotus node can be configured by setting them in `config.env` inside deployment directory:
+
+  ```bash
+  # All optional
+  # Runs a full node syncing from genesis if none are set
+
+  # BSC network to run (mainnet | testnet) (default: mainnet)
+  CERC_BSC_NETWORK=
+
+  # Whether to sync from a snapshot (true | false) (default: false)
+  # Requires snapshot file with extension .tar.lz4 to be placed in the snapshot directory
+  CERC_USE_SNAPSHOT=
+
+  # Whether to run as a fast node (true | false) (default: false)
+  # Fast node does not generate trie data when syncing
+  CERC_FAST_NODE=
+
+  # Garbage collection mode (full | archive) (default: archive)
+  # Set to archive for archive node
+  CERC_GETH_GCMODE=
+
+  # Logging verbosity (default: 3)
+  # 0=silent, 1=error, 2=warn, 3=info, 4=debug, 5=detail
+  CERC_GETH_VERBOSITY=
+  ```
+
+## Start the deployment
+
+```bash
+laconic-so deployment --dir bsc-node-deployment up
+```
+
+## Check status
+
+* To list down and monitor the running containers:
+
+  ```bash
+  # With status
+  docker ps -a
+
+  # Check logs for a container
+  docker logs -f <CONTAINER_ID>
+  ```
+
+* Log in with bash into the bsc container:
+
+  ```bash
+  docker exec -it <BSC_CONTAINER_ID> bash
+  ```
+
+* Check Synchronization:
+
+  ```bash
+  # Inside the bsc container
+
+  # Start geth console
+  geth attach ipc:node/geth.ipc
+
+  >eth.syncing
+  ```
+
+* Check geth logs:
+
+  ```bash
+  # Inside the bsc container
+  tail -f /data/bsc.log
+  ```
+
+## Clean up
+
+* Stop all services running in the background:
+
+  ```bash
+  # Stop the docker containers
+  laconic-so deployment --dir bsc-node-deployment down
+  ```
+
+* To stop all services and also delete data:
+
+  ```bash
+  # Stop the docker containers
+  laconic-so deployment --dir bsc-node-deployment down --delete-volumes
+
+  # Remove deployment directory (deployment will have to be recreated for a re-run)
+  rm -r bsc-node-deployment
+  ```
