+# 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
+  ```
