 Verify that **s2i** is in your PATH.  If not, then edit your PATH and add the directory where **s2i** is installed.  The **manage** script will look for the **s2i** executable on your PATH.  If it is not found you will get a message asking you to download and set it on your PATH.
     - If you are using a Mac and have Homebrew installed, the following command will install s2i: `brew install source-to-image`
     - If you are using Linux, go to the [releases](https://github.com/openshift/source-to-image/releases/latest) page and download the correct distribution for your machine. Choose either the linux-386 or the linux-amd64 links for 32 and 64-bit, respectively. Unpack the downloaded tar with `tar -xvf "Release.tar.gz"`
