Chapter 2
Install & first run
Buckley is not on the AppExchange yet. This chapter lands with the package.
The managed package is still being put together. Once it is listed, this page will cover installation, the permission set, and what to expect the first time you open the app.
In the meantime
The rest of the guide describes Buckley as it works today, and none of it depends on how you got the package installed. If you are evaluating rather than installing, chapter 1 is the honest overview and chapter 4 is the part people want to see.
