## Iridium ## Iridium
Corten is based on Fletcher Haynes's [So you want to build a language VM](https://blog.subnetzero.io/post/building-language-vm-part-01/) tutorial. His virtual machine used for the tutorial is known as [Iridium](https://github.com/fhaynes/iridium). Despite it's origins, it does aim to be full a fledged virtual machine and is already on it's [third iteration](https://gitlab.com/fletchercp/iridium3) with support for SSH, PIDs and Strings. Corten aims to be Iridium 1-compatible. Corten is based on Fletcher Haynes's [So you want to build a language VM](https://blog.subnetzero.io/post/building-language-vm-part-01/) tutorial.
