The OpenZeppelin SDK project used to be named ZeppelinOS. This repository had the source code for the old website of that project.
After the rename, the new website is https://openzeppelin.com/sdk. Read more about it here: https://forum.zeppelin.solutions/t/we-re-changing-the-company-name-from-zeppelin-to-openzeppelin/1047
This repository now hosts only a netlify redirect from the old website to the new one.
