# Build

### Before you begin

Before you begin, make sure to do the following:

* [InfraDID](https://docs.infrablockchain.net/infrablockchain-docs/infrablockchain/service-chains/infra-did-parachain)

### The InfraDID Chain

If you have completed the previous tutorial, you should have the ***InfraRelayChain*** repository on your local machine.

1. Open your computer's terminal shell.
2. Execute the following command to clone InfraDID chain repository:

   ```bash
   git clone https://github.com/InfraBlockchain/infra-did-substrate
   ```

   This command clones the `develop` branch.
3. Execute the following command to navigate to the root of the node template directory:

   ```bash
   cd infra-did-substrate
   ```

   Create a new branch for your work:

   ```bash
   git switch -c my-learning-branch-yyyy-mm-dd
   ```

   Replace `yyyy-mm-dd` with your desired identifier. We recommend using a numeric year-month-day format. For example:

   ```bash
   git switch -c my-learning-branch-2023-03-01
   ```
4. Compile the node template with the following command:

   ```bash
   cargo build --release
   ```

   Always use the `--release` flag for optimized builds. The first compilation may take some time to complete. When it's finished, you'll see a line similar to this:

   ```bash
   Finished release [optimized] target(s) in 11m 23s
   ```

### Starting a Local Node

Once the node is compiled, you're ready to set up the relay chain and InfraDID chain in a local environment using the ZombieNet.

To start the local InfraDID chain, follow these steps:

1. Check the ZombieNet configuration:

   ```bash
   cat ./zombienet/local-dev.toml
   ```

   ```toml
    [relaychain]
    default_command = "../infra-relay-chain/target/release/infrablockspace"
    default_args = ["-lparachain=debug", "-l=xcm=trace"]
    chain = "infrablockspace-local"

    [[relaychain.nodes]]
    name = "alice"
    validator = true
    rpc_port = 7100
    ws_port = 7101

    [[relaychain.nodes]]
    name = "bob"
    validator = true
    rpc_port = 7200
    ws_port = 7201

    [[relaychain.nodes]]
    name = "charlie"
    validator = true
    rpc_port = 7300
    ws_port = 7301

    [[relaychain.nodes]]
    name = "dave"
    validator = true
    rpc_port = 7400
    ws_port = 7401

    [[relaychain.nodes]]
    name = "eve"
    validator = true
    rpc_port = 7500
    ws_port = 7501

    [[relaychain.nodes]]
    name = "ferdie"
    validator = true
    rpc_port = 7600
    ws_port = 7601

    [[parachains]]
    id = 1337
    chain = "infra-did-substrate-local"
    cumulus_based = true

    # run alice as parachain collator
    [[parachains.collators]]
    name = "alice"
    validator = true
    command = "./target/release/infradid"
    args = ["-lparachain=debug", "--alice"]
   ```

   Ensure that the `default_command` paths for `relaychain` and `parachains` match existing paths in your local environment. If they don't match, adjust them to fit your local setup.
2. Execute the following command to run ZombieNet and set up the relay chain and chain:

   ```shell
   zombienet spawn --provider native zombienet/local-dev.toml
   ```
3. If everything is running successfully, you will see a terminal shell similar to the one below:

   ![zombienet](https://3394686052-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F5FcHUSDzEQOuSRhER7FQ%2Fuploads%2Fgit-blob-0a0fdec43fa3bba16d73d21a0fe9359c22f5b6d2%2Finfra-did-parachain-zombienet.png?alt=media)
4. (Optional) If you want to check the nodes of InfraDID chain, you can find logs similar to this:
