   * Java Edition ((https://www.minecraft.net/download/alternative))
-===== Notes =====
+===== Prerequisites =====
-  * :!: TODO all of this
+  * [[distros:fedora_workstation_gnome|Fedora Workstation]]
-==== Copyright Footer ====
-  * ''jagexappletviewer.jar'' from ''OldSchool.msi'' was used because it allows the copyright footer bar to be removed upon logging in (([[https://github.com/rsu-client/rsu-client/commit/b2553e5aeca9a0e6b271b5b17eee9a57c8d6ef11|rsu-client commit]] and [[https://github.com/rsu-client/rsu-client/issues/127|initial bug report]])) ((the previously used direct-link ''jagexappletviewer.jar'' can be found [[http://oldschool.runescape.com/downloads/jagexappletviewer.jar|here]]))
-  * :!: The copyright footer is **not** hidden with OpenJDK 12, 13, and presumably any JRE newer than 11 if ''jagexappletviewer.jar'' comes from ''OldSchool.msi'' ((last tested 2019/10/22))
-  * :!: The copyright footer is **only** hidden with ''jagexappletviewer.jar'' from ''OldSchool.dmg'' if ''-Djava.system.class.loader=app.systemclassloader'' is set on both macOS and Linux hosts ((this flag doesn't work with the ''jagexappletviewer.jar'' from ''OldSchool.msi''))
 ====== Install ======
-===== Dependencies =====
+===== Java =====
-  * ''wmctrl'' is used to toggle between windowed and fullscreen states
+****
-==== Fedora Workstation ====
-  * ''p7zip-plugins'' is needed to extract ''jagexappletviewer.jar'' from ''OldSchool.dmg'' later ((only ''7z'' can do this properly and **not** ''7za'', ''cabextract'', nor ''unar'')) ((this is expected to already be installed from the Fedora prerequisite))
-  * Last tested: 2019/11/01 with Fedora Workstation 31 and OpenJDK 13
-  sudo dnf install java-latest-openjdk wmctrl && sync
-==== Ubuntu ====
-  * Last tested: 2019/10/22 with Ubuntu 19.10
-  * :!: TODO: Update the OpenJDK version and test with the new applet source
-  sudo apt install openjdk-11-jre wmctrl && sync
-==== openSUSE Tumbleweed ====
-  * Last tested: N/A
-  * :!: TODO: Update the OpenJDK version and test with the new applet source
