while looking into why certain github handles were not picked up and I noticed this was missing and it seems pretty useful

• Locally

  Description: William lives in the beautiful Cape Town, South Africa. He enjoys running and moutain biking and when the weather permits (and his motivation) he can be out riding some trail at a wine
  farm or taking a leisure run. Besides the outdoor stuff, he loves to tinker and can often be found working on one of his side projects and reading up a storm on either tech, sci-fi, or fantasy! He
  loves animals and can easily be distracted by a dog.
