+#   /home/michel/.config/ghostty/config
+#
+# The template does not set any default options, since Ghostty ships
+# with sensible defaults for all options. Users should only need to set
+# options that they want to change from the default.
+#
+# Run `ghostty +show-config --default --docs` to view a list of
+# all available config options and their default values.

+# Config syntax crash course
+# ==========================
+# # The config file consists of simple key-value pairs,
+# # separated by equals signs.
+# font-family = Iosevka
+# window-padding-x = 2
+#
+# # Spacing around the equals sign does not matter.
+# # All of these are identical:
+# key=value
+# key= value
+# key =value
+# key = value
+#
+# # Any line beginning with a # is a comment. It's not possible to put
+# # a comment after a config option, since it would be interpreted as a
+# # part of the value. For example, this will have a value of "#123abc":
+# background = #123abc
+#
+# # Empty values are used to reset config keys to default.
+# key =
+#
+# # Some config options have unique syntaxes for their value,
+# # which is explained in the docs for that config option.
+# # Just for example:
+# resize-overlay-duration = 4s 200ms

+Optolith Background
+-------------------
+This shader renders the background from the character creator program
+for The Black Eye 5 "Optolith". 
+
+The default values are to make the shader as close to the original as 
+possible. Thus I recommend using the fullscreen mode to view it, to
+reduce flickering.
+
+This is primarily designed to be used as ghostty shader, which
+requires the use of the iChannel0 channel. But feel free to use it 
+everywhere you like.
+
+If you have any idea of improving it, feel free to let me know or even
+create a fork. :)
+
+I tried to make it as simple as possible and to document everything.
+So even if you have no clue, whats going on, I hope my explainations 
+are good enough, so you know what you can change and how.
