 Sopel itself has few external dependencies, besides Python. There are a couple, though:
 
 * [dnspython](https://github.com/rthalley/dnspython) - used internally to enhance connection reliability
-* [requests](https://github.com/requests/requests) - used to maintain compatibility with old modules that still try to use Sopel's `web` utility functions
-* sqlite - included with all supported Python releases
+* [requests](https://github.com/requests/requests) - used to maintain compatibility with old plugins that use deprecated features of Sopel's `web` utility API
+* [SQLAlchemy](https://github.com/sqlalchemy/sqlalchemy) - used for database cross-compatibility (SQLite, MySQL, PostgreSQL, etc.)
 
-Most of Sopel's dependencies are only needed for specific modules. Below is a listing of some of these. If you don't want to use a specific module, you do not need its dependencies.

 * [geoip2](https://github.com/maxmind/GeoIP2-python) - ip. You will also need the appropriate database files, which Sopel will download automatically if they are not found.
-* [ipython](https://github.com/ipython/ipython) - ipython
+* [ipaddress](https://github.com/phihag/ipaddress) - url (only needed on Python 2)
 * [praw](https://github.com/praw-dev/praw) - reddit
-* [pyenchant](https://github.com/rfk/pyenchant) - spellcheck. You may also need to install the system-level `enchant` library.
 * [pytz](https://launchpad.net/pytz) - remind, clock, seen, tell

 Most of these packages can be installed through the `pip` command, or via your Linux distribution's software repository. If you install Sopel through `pip` or your distribution's package manager (on Fedora or Arch), all of these dependencies will be installed for you.
