## Installation instructions

[package/tao](https://github.com/oat-sa/package-tao) and follow the installation instructions.

If you installed your TAO instance through [package/tao](https://github.com/oat-sa/package-tao),
`oat-sa/extension-tao-outcomerds` is very likely already installed. You can verify this under _Settings -> Extension
manager_, where it would appear on the left hand side as `taoOutcomeRds`. Alternatively you would find it in
the code at `/config/generis/installation.conf.php`.
