Requirements may be added, updated, and removed with 'go get'.
The vendor directory may be updated with 'go mod vendor'.
A typical sequence might be:

    go mod tidy

### Using MinIO Console

- Open MinIO URL on the browser, lets say <http://localhost:9000/>
- Click on `Login with SSO`
- User will be redirected to the Keycloak user login page, upon successful login the user will be redirected to MinIO page and logged in automatically,
