    Moov ACHGateway is an extensible, highly-available, distributed, and fault-tolerant ACH uploader and downloader. ACHGateway creates events for outside services and transforms files prior to upload to fit real-world requirements of production systems.

    Refer to the documentation site for more information on running ACHGateway. https://moov-io.github.io/achgateway/

    description: |
      Shards are logical grouping for ACH file delivery. They are designed to allow a large number of identifiers map to a small number
      of upload agents and schedules. This allows customization to match business and banking requirements. Identifiers can be random
      values (e.g. UUIDs) with shard names (e.g. testing, SD-live).

      Endpoints for monitoring ACHGateway and triggering manual steps outside of the automated processes.

      There are endpoints for liveness/readiness checks and Prometheus metrics. The [`admin` package from `moov-io/base` describes these endpoints](https://github.com/moov-io/base/tree/master/admin#endpoints).

        JSON specification. When ValidateOpts are required the JSON specification must be used.
