Write a Bible study. Read the Bible and view and edit your notes, filling in the details until you have a complete study. See the help on the Chapters page to learn about reading and taking notes, but notice that from that page you always tie notes to the chapter or book you're reading and tying notes to a study is optional, but when you write a study from this page you always tie notes to the study you're writing and the chapter is optional. This is why the Notes panel looks a bit different here then it does on the Chapters page.
To include a Bible passage in your study text find the passage using the Chapters panel, from this page or from any page that has a Chapters panel, then copy and paste the passage into your study. This way you pick up any text annotations that the Generate page needs to format PDFs. For example, italicized words have square brackets around them in the Chapters panel, and they're removed and replaced with italics in the PDF. Also, if you want a passage with self-pronunciation marks or POS tags then request that in the Chapters panel to get the annotations, and copy and paste as usual. The Generate tool can ignore annotations you don't want in a particular PDF, but it can't add any that you haven't put into the text.
From this page you don't have direct access to the Concordance or Context search tools, but you can open them in separate browser windows or tabs. Any changes to your notes that you save from one page will appear in every other page.
When the study's ready, use the Generate page to turn it into PDFs. If the study has a description, that's used as the title in PDFs, otherwise the study ID is the title.
When you change a study the original study is still available for about seven days. Select Versions to reveal buttons for browsing old versions of the current study. Each browse shows the timestamp of the browsed-to version, replaces the study text with that version, and allows you to make edits to it. When you're done press Save at the bottom as usual, or at any time press Cancel to go back to the study as you last saved it, and to stop browsing versions.
If Save and Cancel aren't available that means the on-screen study text is exactly the same as the last saved text, so if you're browsing versions that means you've browsed to a version that happens to be identical to the study as you last saved it. In this case if you're done browsing verions then uncheck the Versions checkbox to hide the browsing buttons.
There's no button for deleting old versions; they age out automatically after about a week.
