This section provides an overview of what twig is, and why a developer might want to use it.
It should also mention any large subjects within twig, and link out to the related topics. Since the Documentation for twig is new, you may need to create initial versions of those related topics.
Please note that the Twig extension is not compatible with PHP7 and although there is a pull request to resolve this situation it was not yet made part of version 1.x. With the most recent Twig 2.x release the C extension was removed but might be part of 2.1. Some benchmarks reveal minimal improvements with the C extension under PHP7.
