+# Graph Node
+
+## Setup
+
+Clone required repositories:
+
+```bash
+laconic-so --stack graph-node setup-repositories --pull
+```
+
+Checkout to a non-default branch in the cloned repos if required:
+
+```bash
+# Default repo base dir
+cd ~/cerc
+
+# Example
+cd graph-node
+git checkout <your-branch> && git pull
+
+# Remove the corresponding docker image if it already exists
+docker image rm cerc/graph-node:local
+# Remove any dangling images
+docker image prune
+```
+
+Build the container images:
+
+```bash
+laconic-so --stack graph-node build-containers
+```
+
+## Create a deployment
+
+Initialize deployment and create "spec" file:
+
+```bash
+laconic-so --stack graph-node deploy init --output graph-node-spec.yml
+```
+
+We need to assign fixed ports: `8000` for subgraph GQL endpoint, `8020` for subgraph deployment and `5001` for IPFS. The values can be
+customized by editing the "spec" file generated by `laconic-so deploy init`.
+```
+$ cat graph-node-spec.yml
+stack: graph-node
+ports:
+  graph-node:
+    - '8000:8000'
+    - '8001'
+    - '8020:8020'
+    - '8030'
+  ipfs:
+    - '8080'
+    - '4001'
+    - '5001:5001'
+...
+```
+
+Create deployment:
+
+```bash
+laconic-so deploy create --spec-file graph-node-spec.yml --deployment-dir graph-node-deployment
+```
+
+## Start the stack
+
+Create an env file with the following values to be set before starting the stack:
+
+```bash
+# Set ETH RPC endpoint the graph node will use
+
+# Host and port of the ETH RPC endpoint to check before starting graph-node
+export ETH_RPC_HOST=
+export ETH_RPC_PORT=
+
+# The etherum network(s) graph-node will connect to
+# Set this to a space-separated list of the networks where each entry has the form NAME:URL
+export ETH_NETWORKS=
+```
+
+Example env file:
+
+```bash
+export ETH_RPC_HOST=filecoin.chainup.net
+export ETH_RPC_PORT=443
+
+export ETH_NETWORKS=filecoin:https://filecoin.chainup.net/rpc/v1
+```
+
+Set the environment variables:
+
+```bash
+source <PATH_TO_ENV_FILE>
+```
+
+Deploy the stack:
+
+```bash
+laconic-so deployment --dir graph-node-deployment start
+
+# Note: Remove any existing volumes in the cluster for a fresh start
+```
+
+After all services have started, follow `graph-node` logs:
+
+```bash
+laconic-so deployment --dir graph-node-deployment logs -f graph-node
+```
+
+Subgraphs can now be deployed to the graph-node.
+Follow [Deploy the Subgraph](https://github.com/graphprotocol/graph-node/blob/v0.32.0/docs/getting-started.md#24-deploy-the-subgraph) section in graph-node docs for an existing subgraph.
+
+## Set environment variables
+
+* The graph-node environment variable `ETHEREUM_REORG_THRESHOLD` can be set in the deployment compose file
+  ```bash
+  $ cat graph-node-deployment/compose/docker-compose-graph-node.yml
+  services:
+    graph-node:
+      image: cerc/graph-node:local
+      ...
+      environment:
+        ...
+        GRAPH_LOG: debug
+        ETHEREUM_REORG_THRESHOLD: 3
+  ```
+  Change `ETHEREUM_REORG_THRESHOLD` to desired value
+
+  * To restart graph-node with updated values
+    * Stop the stack first
+      ```bash
+      laconic-so deployment --dir graph-node-deployment stop
+      ```
+    * Start the stack again
+      ```
+      laconic-so deployment --dir graph-node-deployment start
+      ```
+  * To check if environment variable has been updated in graph-node container
+      ```bash
+      $ laconic-so deployment --dir graph-node-deployment exec graph-node bash
+      root@dc4d3abe1615:/# echo $ETHEREUM_REORG_THRESHOLD
+      16
+      ```
+
+## Clean up
+
+Stop all the services running in background run:
+
+```bash
+laconic-so deployment --dir graph-node-deployment stop
+```
+
+Clear volumes created by this stack:
+
+```bash
+laconic-so deployment --dir graph-node-deployment stop --delete-volumes

+# Deploying Subgraph
+
+## Setup
+
+We will use the [ethereum-gravatar](https://github.com/graphprotocol/graph-tooling/tree/%40graphprotocol/graph-cli%400.58.0/examples/ethereum-gravatar) example subgraph from `graphprotocol/graph-tooling` repo
+
+- Clone the repo
+  ```bash
+  git clone git@github.com:graphprotocol/graph-tooling.git
+  
+  cd graph-tooling
+  ```
+
+- Install dependencies
+  ```bash
+  pnpm install
+  ```
+
+- Change directory to example-subgraph
+  ```bash
+  cd examples/ethereum-gravatar
+  ```
+
+## Deploy
+
+The following steps should be similar for every subgraph
+
+- Change the network and address in `subgraph.yaml`
+  ```yaml
+  ...
+  dataSources:
+  - kind: ethereum/contract
+    name: Gravity
+    network: <NETWORK_NAME>
+    source:
+      address: '<CONTRACT_ADDRESS>'
+      abi: Gravity
+      startBlock: <START_BLOCK>
+  ...
+  ```
+  - `CONTRACT_ADDRESS` is the address of the deployed contract on the desired network
+  - `START_BLOCK` is the block number after which we want to process events
+  - `NETWORK_NAME` is the name of the network specified when deploying graph-node
+    - When deploying graph-node `ETH_NETWORKS` env is set to a space-separated list of the networks where each entry has the form `NAME:URL`
+    - The `NAME` can be used in subgraph to specify which network to use
+    - More details can be seen in [Start the stack](./README.md#start-the-stack) section
+
+- Build the subgraph
+  ```bash
+  pnpm codegen
+  pnpm build
+  ```
+
+- Create and deploy the subgraph
+  ```bash
+  pnpm graph create example --node <GRAPH_NODE_DEPLOY_ENDPOINT>
+  
+  pnpm graph deploy example --ipfs <GRAPH_NODE_IPFS_ENDPOINT> --node <GRAPH_NODE_DEPLOY_ENDPOINT>
+  ```
+  - `GRAPH_NODE_DEPLOY_ENDPOINT` and `GRAPH_NODE_IPFS_ENDPOINT` will be available after graph-node has been deployed
+  - More details can be seen in [Create a deployment](./README.md#create-a-deployment) section 
+
+- The subgraph GQL endpoint will be seen after deploy command runs successfully
+
+- To remove the subgraph
+  ```bash
+  pnpm graph remove --node <GRAPH_NODE_DEPLOY_ENDPOINT> example
+  ```
