# Basic Consul API Gateway Usage

This topic describes how to use Consul API Gateway.

## Requirements

Complete the following steps to use Consul API Gateway in your network.

1. Verify that the [requirements](/consul/docs/api-gateway/tech-specs) have been met.
1. Verify that the Consul API Gateway CRDs and controller have been installed and applied. Refer to [Installation](/consul/docs/api-gateway/install) for details.

## Configuration

Configure your [`Gateway`](/consul/docs/api-gateway/configuration/gateway) and [`Routes`](/consul/docs/api-gateway/configuration/routes) as described in [Consul API Gateway Configuration](/consul/docs/api-gateway/configuration).

  <CodeBlockConfig hideClipboard filename="values.yaml">

    ```yaml
      apiGateway:
        enabled: true
        managedGatewayClass:
    ```

  </CodeBlockConfig>

## Apply configurations

Issue the `kubectl apply` command to implement the configurations:

  ```shell-session
    $ kubectl apply -f gateway.yaml routes.yaml
  ```

### Using the Consul API Gateway Binary

You can download the Consul API Gateway binary and use it to manually start the control plane server.

1. Download the binary from the [Consul API Gateway repository](https://github.com/hashicorp/consul-api-gateway).
1. Navigate to the `consul-api-gateway-main` directory and build the binary:

```shell-session
$ go build
```

1.  (Optional) Copy the binary to the execution path, e.g.:

```shell-session
$ cp consul-api-gateway /usr/bin
```

1.  Use the `server` command to interact with the Consul API Gateway binary:

```shell-session
$ ./consul-api-gateway server <options>
```

The following options are supported:
