+
+# order
+# Markov chains are naiive models of how a certain person speaks. Chains have an
+# "order", which is close to the "accuracy" of the way a person speaks. The
+# larger the order, the more RAM and hard drive space is used.
+# An order of 1 or 2 is recommended, anything larger gets pretty huge in memory.
+# default: 1
+# order = 1
+
+# data_path
+# This is the path to the directory that holds the markov chains. Chains are
+# stored by channel, and then bey user.
+# For example, data/markov/#chat/nick holds the data for the user "nick".
+# default: data/markov/
+# data_path = "data/markov"
+
+# save_every
+# Markov chains for all users are saved periodically. This value determine the
+# number of seconds between saves.
+# If a user's markov chain is not accessed after their last save, it is pruned
+# from memory.
+# default: 1800
+# save_every = 1800
+
+# reply_chance
+# Whenever someone says something, the bot will train their markov chain based
+# on what they've said. Sometimes, when someone says something, the bot will
+# interject its opinion about the state of affairs, based on that user. This is
+# based on a random chance. The supplied number should be be between 0.0 and
+# 1.0, from "never" to "always".
+# Additionally, users may set their reply chance between 0.0 and the value they
+# set. e.g. with a value of 0.01, a user may set their reply chance to 0.001.
+# default: 0.01
+# reply_chance = 0.01
