 # libsidplay
 
+This library provides the Sound Interface Device (SID) chip emulator
+engine that is used by music player programs like SIDPLAY.
+With it you can play musics from Commodore 64 (or compatible) programs.
+
+Because the original homepage of SIDPlay (http://www.geocities.com/SiliconValley/Lakes/5147/resid)
+disappeared from Internet some time ago,
+I decided to set up this unofficial page for providing a semi-regularly updated tarballs of libSIDPlay1.
+However, I have no intention of adding any new features, at most I will fix compilation and portability related bugs.
