If you just want to try FOLIO without installing it, you can run one of the pre-built Vagrant boxes.
If you are a developer, you can get a FOLIO installation up and running quickly using a pre-built Vagrant box. These virtual machines have a Single server installation of FOLIO running. The Stripes and Okapi services can be accessed via port forwarding. You can create new modules on the host operating system and connect them to Okapi using a host only network that allows bidirectional connections between the host and the guest operating system. Please see https://github.com/folio-org/folio-ansible/blob/master/doc/index.md for more information on Vagrant boxes.
