 ## Playing
 
-`ssb` requires a directory for storing the level database. Although write-access
-is not required, it does allow for levels and metadata to be saved. This
-directory defaults to `./levels`, but can be specified by the

+`ssb` can ran as either a multi-player Telnet server, or as a single-player

+Both modes require a database and optionally, a folder of existing levels to
+import. The path to the database file can be specified using
+`-d path/to/db.sqlite` (defaulting to `./ssb.sqlite` otherwise), and the path
+to the levels folder can be specified using `-l path/to/levels/` (defaulting
+to `./levels/`).

 ## History
 
-"Super Serif Brothers" was released by Robin Allen in the early days of
-web-based games.
-
-The original game also featured a "level pit" in which players could design and
-upload their own levels. Unfortunately, a good chunk of these designs were lost
-and only a small number could be recovered from archive.org records.
+"[Super Serif Brothers](https://foon.uk/farcade/ssb/)" was a web platformer
+created by [Robin Allen](https://foon.uk/) in the early days of the internet.
+This is a faithful recreation that takes the ASCII game one step further and
+brings it into the terminal.
+
+The original game included fourteen 80x25 character levels, plus a "level pit"
+where netizens could share their own level designs -- some wonderful works of
+art that pushed the format to its limits, among other levels that serve as more
+of "digital graffiti." Unfortunately a good chunk of these player-submitted
+levels have been lost to time. Those that could be recovered are included,
+along with the original fourteen levels, in the `levels` directory.
