+
+**GstLAL** provides a suite of GStreamer elements that expose gravitational-wave data analysis tools from the LALSuite library for use in GStreamer signal-processing pipelines.
+
+Examples include an element to add simulated gravitational waves to an h(t) stream, and a source element to provide the contents of .gwf frame files to a GStreamer pipeline.
+Overview
+
+The **GstLAL** software package is used for the following activities:
+
+  * GstLAL: Provides core Gstreamer plugins for signal processing workflows with LIGO data and core python bindings for constructing such workflows.
+  * GstLAL Calibration: Provides real-time calibration of LIGO control system data into strain data.
+  * GstLAL Inspiral: Provides additional signal processing plugins that are specific for LIGO / Virgo searches for compact binaries as well as a substantial amount of python code for post-processing raw signal processing results into gravitational wave candidate lists. Several publications about the methodology and workflow exist, see publications
+  * GstLAL Ugly: An incubator project for gradual inclusion in the other packages.
