+=========================
 
 
-   Detector Server
-   ---------------
+    Python
+    ------
 
 
-    *   [Mythen3] Fix trimbits and badchannels
-        They were shifted by 1. Fixed.
+    *   Python module is now built using scikit-build-core
+    
+
+    *   slsdet is available on PyPI from this release onwards
 
 
-    Receiver
-    --------
-
-
-    *   slsFrameSynchronizer - does not stream out frames
-        It streamed out start and stop zmq packets but did 
-        not stream out frames with no error message. Fixed.
-        Updated documentation.
-
-
-    *   slsMultiReceiver - 3rd Command line argument (vebose option)
-        When this option to print headers is enabled, the sample call back 
-        headers update the image size to a random number 26112. This 
-        is fixed and left commented out for easy reference for users.
+    *   Updated documentation on python module installation

+
+Overview
+--------------
+
+The ``slsDetectorPackage`` provides core detector software implemented in C++, along with Python bindings packaged as the ``slsdet`` Python extension module. Choose the option that best fits your environment and use case.
+
+:ref:`conda pre-built binaries`: 
+Install pre-built binaries for the C++ client, receiver, GUI and the Python API (``slsdet``), simplifying setup across platforms.
+
+:ref:`pip`:
+Install only the Python extension module, either by downloading the pre-built library from PyPI or by building the extension locally from source. Available only from v9.2.0 onwards.
+
+:ref:`build from source`: 
+Compile the entire package yourself, including both the C++ core and the Python bindings, for maximum control and customization. However, make sure that you have the :doc:`dependencies <../dependencies>` installed. If installing using conda, conda will manage the dependencies. Avoid installing packages with pip and conda simultaneously.
+

-    Before building from source make sure that you have the
