 The sigrok project aims at creating a portable, cross-platform,
-Free/Libre/Open-Source logic analyzer software that supports various
-logic analyzer hardware products.
+Free/Libre/Open-Source signal analysis software suite that supports various
+device types (such as logic analyzers, oscilloscopes, multimeters, and more).
 
 libsigrok is a shared library written in C which provides the basic API
-for talking to logic analyzer hardware and reading/writing the acquired data
-into various input/output file formats.
+for talking to hardware and reading/writing the acquired data into various
+input/output file formats.
+
+
+Status
+------
+
+libsigrok is in a usable state and has had official tarball releases.
+
+While the API can change from release to release, this will always be
+properly documented and reflected in the package version number and
+in the shared library / libtool / .so-file version numbers.
+
+However, there are _NO_ guarantees at all for stable APIs in git snapshots!
+Distro packagers should only use released tarballs (no git snapshots).
