-# Scuba Client Library
-
-This repository provides a client library for the Scuba service.
-The repository also provides a CLI binary to interact with the
-Scuba Service.
-
-The supported operations are:
-
-- Get the utilization metrics at a given time
-- Get the latest utilization metrics
-- Check the health of the Scuba service
-
-## Contributing
-
-In order to contribute, please follow the
-[Contributing Guidelines](
-https://github.com/scality/Guidelines/blob/master/CONTRIBUTING.md).
-
-## Prerequisite
-
-- Recommended Node version: >16.x.
-- Yarn must be installed to build the project.
-- An Open API yaml file defining the routes to use.
-
-Node.js can be installed from [nodejs.org](https://nodejs.org/en/download/) and
-Yarn can be installed from [yarnpkg.com](https://yarnpkg.com/en/docs/install).
-
-## Usage
-
-To generate the client, run the following command:
-
-```bash
-./bin/generate-client.sh
-```
-
-### Authentication
-
-ScubaClient supports AWS Signature Version 4 authentication. To use this
-authentication method, you must have a set of credentials with permission
-to perform the desired operations.
-
-### Command-Line Interface
-
-Command-line support is not yet available.
