The starter kit documentation is hosted using GitHub pages at https://ibm-blockchain-starter-kit.github.io/ using the Jekyll Doc Theme.
All the documentation is written in Markdown in files under the pages directory.
To add a new page, you may also want to include it in a sidebar, which you can find under the _data/sidebars directory.
For more details, including how to build the documentation locally, read the Jekyll Doc Theme's getting started guide.
