+[A SlackBuild](https://codeberg.org/glowiak/SlackBuilds/src/branch/master/repository/polymc.md) is available. You will need [qt5](http://slackbuilds.org/repository/14.2/libraries/qt5/) (on 15.0 installed by default), [a JDK](https://codeberg.org/glowiak/SlackBuilds/src/branch/master/repository/adoptium-jdk8.md), and if you're on 14.2, you need to compile newer CMake version manually. To build, type in extracted directory with all dependiences met:
+
+    sudo ./polymc.SlackBuild
+    sudo installpkg /tmp/polymc-version-arch-1_SBo.tgz
+
+If you are too lazy to do all these steps, you can just download [a prebuild x86_64 package](http://glowiak.github.io/file/polymc-latest-slackware) and install it with /sbin/installpkg:
+
+    sudo /sbin/installpkg ~/Downloads/polymc-version-x86_64-1_SBo.tgz
