# Deploying an Indexer (Subgraph) on Celo with The Graph

> Step-by-step guide to deploying a subgraph on Celo using The Graph for efficient blockchain data indexing and querying.

Setting up a subgraph on Celo with Mobula's infrastructure is an easy process. This tutorial will guide you through each step to get your subgraph operational on the Celo network.

### What you’ll need

* Basic knowledge of The Graph and subgraphs.
* Your subgraph project files
* The Graph CLI installed
* A Mobula API key (for authentication)

### Walkthrough

<Steps>
  <Step title="Prepare Your Subgraph">
    Configure your subgraph for Celo. Adjust your `subgraph.yaml` file to reference Celo-specific contracts and events. If you don't have a subgraph yet, you can clone the Uniswap V2 subgraph template and tailor it for Celo:

    ```bash theme={null}
    git clone https://github.com/MobulaFi/univ2-subgraph-celo
    ```
  </Step>

  <Step title="Install Dependencies">
    Make sure you have The Graph CLI installed:

    ```bash theme={null}
    npm install -g @graphprotocol/graph-cli
    ```
  </Step>

  <Step title="Install Mobula CLI">
    Install our CLI tool using npm:

    ```bash theme={null}
    npm i mobula-cli
    ```
  </Step>

  <Step title="Setup API Key">
    Configure your API key with the CLI. You can get your API key from the [Dashboard](https://admin.mobula.io).
    Please refer to the [authentication section](/indexing-stream/authentification) for detailed steps on obtaining your API key.

    ```bash theme={null}
    mob apikey set
    ```
  </Step>

  <Step title="Build Your Subgraph">
    Compile your subgraph before deployment:

    ```bash theme={null}
    graph codegen && graph build
    ```
  </Step>

  <Step title="Deploy your subgraph">
    Deploy your subgraph using the Mobula CLI:

    ```bash theme={null}
    mob deploy -n subgraphName
    ```
  </Step>

  <Step title="Monitor Deployment">
    After deployment, you'll receive a URL to monitor your subgraph's indexing progress and status.
  </Step>
</Steps>

### Best Practices

* Ensure your subgraph is consistently updated to stay compatible with the latest Celo network changes.
* Perform thorough testing on a testnet before deploying to the mainnet.
* Regularly monitor its performance and optimize queries for improved efficiency.

### Troubleshooting

If you face issues during deployment:

* Review your `subgraph.yaml` file carefully.
* Ensure the network name and Mobula node URLs are correct.
* Check that your API key is valid and has the appropriate permissions.
