There is a rich set of documentation for Gateway Engine located on Exosite's main documentation site: Docs > ExositeReady > Gateway Engine.
As the first topic in the Exosite's Community forum on Gateway Engine, I'll quickly say that the first problem developers encounter with Gateway Engine is installing it onto a new gateway. Gateways are heterogeneous with any number of styles of boot environments, operating systems and scripting environments. If you're working with Gateway Engine for the first time or if you're trying to work with it on a new platform/gateway and the installation is working as expected
- Take good notes
- Collect logs
- Note the version of Gateway Engine
- Note any/all metadata about the platform/gateway
and then raise a new topic on this forum with the name/type/model of the platform/gateway as the topic.
