+The looks and ways of the REPL can be fine-tuned via a bunch of
+customization variables. You can see and modify them all in the
+corresponding customization group (by using the menu entry or the good
+old @kbd{M-x customize-group geiser-repl}), or by setting them in your
+Emacs initialization files (as a rule, all knobs in Geiser are turnable
+this way: you don't need to use customization buffers if you don't like
+them).
+
+I'm documenting below a proper subset of those settings, together with
+some related tips.
+
+@subsubheading Choosing a Scheme implementation
+Instead of using the generic @command{run-geiser} command, you can start
+directly your Scheme of choice via @command{run-racket} or
+@command{run-guile}. @anchor{active-implementations} In addition, the
+variable @var{geiser-active-implementations} contains a list of those
+Schemes Geiser should be aware of. Thus, if you happen to be, say, a
+racketeer not to be beguiled by other schemes, you can tell Geiser to
+forget about the richness of the Scheme ecosystem with something like
+@example
+(setq geiser-active-implementations '(racket))
+@end example
+@noindent in your initialisation files.
+
+@anchor{impl-binary} When starting a new REPL, Geiser assumes, by
+default, that the corresponding Scheme binary is in your path. If that's
+not the case, the variables to tweak are @var{geiser-guile-binary} and
+@var{geiser-racket-binary}, which should be set to a string with the
+path to the adequate binary.
+
+@subsubheading History
+
+By default, Geiser won't record duplicates in your input history. If you
+prefer it did, just set @var{geiser-repl-history-no-dups-p} to
+@code{nil}. History entries are persistent across REPL sessions: they're
+saved in implementation-specific files whose location is controlled by
+the variable @var{geiser-repl-history-filename}. For example, my Geiser
+configuration includes the following line:
+@example
+(setq geiser-repl-history-filename "~/.emacs.d/geiser-history")
+@end example
+@noindent which makes the files @file{geiser-history.guile} and
+@file{geiser-history.racket} to live inside my home's @file{.emacs.d}
+directory.
