 Each connector declares the inputs it needs to read data from the underlying data source. This is the Airbyte Protocol's `spec` operation.
 
-The simplest way to implement this is by creating a `spec.yaml` file in `source_<name>/spec.yaml` which describes your connector's inputs according to the [ConnectorSpecification](https://github.com/airbytehq/airbyte/blob/master/airbyte-protocol/models/src/main/resources/airbyte_protocol/airbyte_protocol.yaml#L257) schema. This is a good place to start when developing your source. Using JsonSchema, define what the inputs are \(e.g. username and password\). Here's [an example](https://github.com/airbytehq/airbyte/blob/master/airbyte-integrations/connectors/source-stripe/source_stripe/spec.yaml) of what the `spec.yaml` looks like for the Stripe API source.
