Why not present it as a library with a sensible API and a directory of example uses. Including an example of a single binary, minimalistic server that has a very simple, minimal interface allowing you to submit documents and review the results? Or even a command line utility that takes a document as input and spits out the result on stdout or a file?
Imagine how much more immediate the experience would be if you can just fetch a binary and run it on the command line. Or how much easier it would be for people who might want to make use of this in, say, a blogging platform, if you could show them a 10-20 line example of how to make use of this as a library in your own code.
If you provide people with a smooth path for bot adoption and extension, the chance of people engaging positively increases. When I'm presented with this project the core problem this solves gets lost in all the pomp and circumstance involved in running it.
