 # This directory menaces with spikes of Nix code. It is terrifying.
 #
 # If this is your first time here, you should probably install the dwarf-fortress-full package,
-# for instance with `environment.systempackages = [ pkgs.dwarf-fortress.dwarf-fortress-full ];`.
+# for instance with:
+#
+# environment.systemPackages = [ pkgs.dwarf-fortress-packages.dwarf-fortress-full ];
 #
 # You can adjust its settings by using override, or compile your own package by
-# using the other packages here. Take a look at lazy-pack.nix to get an idea of
-# how.
+# using the other packages here.
+#
+# For example, you can enable the FPS indicator, disable the intro, pick a
+# theme other than phoebus (the default for dwarf-fortress-full), _and_ use
+# an older version with something like:
+#
+# environment.systemPackages = [
+#   (pkgs.dwarf-fortress-packages.dwarf-fortress-full.override {
+#      dfVersion = "0.44.11";
+#      theme = "cla";
+#      enableIntro = false;
+#      enableFPS = true;
+#   })
+# ]
+#
+# Take a look at lazy-pack.nix to see all the other options.
 #
 # You will find the configuration files in ~/.local/share/df_linux/data/init. If
 # you un-symlink them and edit, then the scripts will avoid overwriting your
 # changes on later launches, but consider extending the wrapper with your
 # desired options instead.
-#
-# Although both dfhack and dwarf therapist are included in the lazy pack, you
-# can only use one at a time. DFHack does have therapist-like features, so this
-# may or may not be a problem.
