+
+It's now possible to build chocolate-doom-3.0.0-beta1 with this script,
+though the default is still to build 2.3.0 (the latest stable release).
+
+If there's ever a 3.0.0-beta2 or -beta3, you may be able to build those
+too. I don't have a time machine, so I can't test them since they don't
+exist yet :)
+
+Manual build
+------------
+
+The beta has switched to using SDL2, so you will need SDL2, SDL2_mixer, and
+SDL2_net installed.
+
+To build the beta version, download the source from:
+
+https://github.com/chocolate-doom/chocolate-doom/archive/chocolate-doom-3.0.0-beta1.tar.gz
+
+The md5sum is: da0439cb91db310c3342461ddd96ce16
+
+Set VERSION to 3.0.0_beta1 in the environment. Example:
+
+# VERSION=3.0.0_beta1 sh ./chocolate-doom.SlackBuild
+
+Notice the _ in the version number! Do not use a hyphen (-), Slackware
+can't handle version numbers with hyphen in them.
+
+
+Tool-assisted build
+-------------------
+
+If you use sbopkg or sbotools, you can replace chocolate-doom.info with
+chocolate-doom.info.beta, either by copy/pasting the contents or just
+copying the file.
+
+
+Config file
+-----------
+
+chocolate-doom's config file location has moved. In 2.3.0, user
+config files were kept in "~/.chocolate-doom/". 3.0.0-beta1 uses
+"~/.local/share/chocolate-doom/". You should be able to just copy your
+*.cfg files from the old location to the new one.
