Doc-sys app

By default, running psinode will deploy this entire documentation site in the doc-sys application. View it by visiting the doc-sys app on your local node's host address (e.g. doc-sys.psibase.127.0.0.1.sslip.io).

Building from source

This documentation can be generated by mdBook when building psibase from source by using the -DBUILD_DOC=yes flag with CMake. mdBook will generate the docs based on the psibase source code and the markdown files in doc/psidk/src/. After building, the documentation can be manually viewed either by booting a local Psibase network and visiting the locally deployed doc-sys app, or by running the mdbook serve command from the build/doc/psidk/ directory within this repository, which will expose the generated documentation at localhost port 3000.
