construct/include/ircd/db/database/env/README.md

This directory contains extremely low-level backend interfaces which allow IRCd to customize the embedded behavior of RocksDB through its callback and virtual interfaces.

These interfaces are not useful to developers wishing to use the ircd::db database interface. These interfaces are furthermore not useful to developers wishing to add functionality to the ircd::db interface either.

You are now two levels away from the public ircd::db interface included in the standard include stack.
