+Caveats (or limitations):
+=========================
+
+* Nick column is fixed and truncated to 10 columns wide.
+  
+  This is something fixable down the line. It merely serves to
+  simplify the alignment of messages into two columns (nick and
+  messages).
+
+* Lines are word-wrapped to a fixed 60 columns.
+
+  This is also fixable down the line though a lot more painful
+  than the nick column issue. POSIX fold is used to achieve the
+  word wrapping but doesn't take into account non-printable
+  characters and unicode.
+
+  What this means is that wrapping will always be a little _off_
+  as escape sequences, IRC formatting and unicode will throw
+  out all attempts at calculating the "visible" line length.
+
+  It's an interesting problem to solve. I've made a myriad of
+  attempts at writing a suitable function in bash though they're
+  all too slow (as expected!).
+
+* No automatic server reconnect.
+
+  This should be fairly easy to fix though I need to figure out
+  the best way of doing so.
+
+* No SSL (sadly).
+
+  The network connection is through bash's builtin /dev/tcp
+  feature which doesn't allow for SSL.
+
+Keybindings:
+============
+
+Ctrl+n - Next buffer.
+Ctrl+p - Previous buffer.
+Tab    - Completion of nicks and channels.
+
+Further, all readline keybindings are available for use. See the
+readline or bash manpages for a list of these. 
+
+Keybindings to birch may also be set via a .inputrc file. Which
+can be configured by setting `$BIRCH_INPUTRC`.
+
