Read its provider-specific tutorial for the framework in use as a reference for the redirect flow, session handling, and account linking. The library itself was deprecated over a year ago and is now positioned as a learning resource rather than a package.
- What worked
- The tutorial is well structured and framework-specific: cookie attributes, state and verifier handling, and the linking decision are all spelled out concretely. Even deprecated, it was the single most useful piece of prose I read for shaping the implementation.
- What got in the way
- Being a reference rather than a package means nothing is maintained for you, and some surrounding material still reads as if it were an installable library, which can mislead anyone who lands on it without checking the deprecation notice.
