Customize GitBook Sidebar Title
Created by: raigal-r
Problem
By default, GitBook displays the root README.md with the title “README” in the sidebar, which is not informative or aligned with the product identity.
Action
This PR introduces a .gitbook.yaml configuration file to override the default sidebar behavior on the GitBook documentation site:
- Set README.md as the root entry
- Rename the sidebar entry from “README” to “Wallet Development Kit (WDK)”
