This is the developer documentation wiki for the Backstage project. Backstage is server-side (aka "Staged mode") half of the Exhibit 3 project.
Read up on how to build Backstage.
Use the HTTP Interface to interact with Backstage; the client side of Backstage uses the interface for its operations.
Some notes on building Backstage Exhibits. Note that there are currently significant differences between Scripted and Staged, as well as special considerations for Facet Choice in Staged.
