13. Frequently Asked Questions (FAQ)

Error

This section represents old content from the <= v4.x FAQ that has not been properly converted to the new-style documentation. The content here was perfunctorily converted to RST, but it still needs to be:

1. Converted from a question-and-answer style to a regular documentation style (like the rest of these docs).

2. Removed from this section and folded into other sections in these docs.

To be clear, this section will eventually be deleted; do not write any new content in this section.

The pages below include questions that we are asked frequently enough that they are worth categorizing in an official way.
