+AstroHACK (Holography and Antenna Comissioning Kit) is a python
+package intended for NRAO telescope support activities, such as
+holography and antenna position corrections.
+
+Currently AstroHACK supports:
+
+- `Astronomical holographies from the VLA <./tutorial_vla.html>`_.
+- Astronomical holographies from ALMA.
+- `Antenna position corrections for the VLA <./locit_tutorial>`_.
+- `Near-field ALMA holographies <./AstroHACK-for-NF-ALMA.html>`_ have
+  basic support, such as the creation of Aperture images, but the
+  correction of near-field effects is not yet supported.
+
+In the near term we are working to support the `ngVLA antenna
+prototype <https://public.nrao.edu/ngvla/>`_ comissioning activities.
+The prototype antenna is currently (March 2025) under construction at
+the VLA site.
+
+The holography tasks in AstroHACK port much of the functionality of
+AIPS holography tasks (UVHOL, HOLOG and PANEL) to a python framework
+that enables us to take advantage of modern parallelization and code
+acceleration technologies, such as `Dask <https://www.dask.org/>`_ and
+`Numba <https://numba.pydata.org/>`_. Making the reduction of
+holography data much faster and streamlined for the user.
 
-(Holography Antenna Commissioning Kit) is a Python package that produces antenna aperture images and panel adjustment corrections from calibrated holography measurement sets. Initially, it will support holography data from the VLA and ALMA, with the future goal of supporting the ngVLA. Much of the core functionality from the following AIPS tasks has been ported: UVHOL, HOLOG, and PANEL. astroHack enables parallel execution by using Dask and efficient single-threaded performance by making use of Numba.
