 %description
-Utility library for configuring the accelerator subsystem.
+Accel-config is an open-source utility library for controlling and configuring
+Intel Data Streaming Accelerator (DSA) and Intel Analytics Accelerator (IAA)
+sub-systems within the Linux kernel. It provides a user-friendly interface to
+configure, manage, and monitor these sub-systems.

-Summary:	Development files for libaccfg
-License:	LGPLv2.1
-Group:		Development/Libraries
-Requires:	%{name}-libs = %{version}-%{release}
+The library supports a range of DSA and IAA hardware accelerators, including
+FPGA-based accelerators, which can perform complex data processing tasks such
+as compression, encryption, and data analytics. The library enables users to
+configure these accelerators to optimize performance for their specific use case.
 
-%description devel
-The %{name}-devel package contains libraries and header files for
-developing applications that use %{name}.
+Accel-config has several key features, including:
+
+Configuration management: Accel-config provides a unified interface to
+configure, manage, and monitor DSA and IAA sub-systems within the Linux kernel.
+Users can modify the configuration of individual hardware accelerators and
+pipelines to optimize performance.
+
+Performance monitoring: Accel-config includes a set of monitoring tools that
+enable users to monitor the performance of DSA and IAA sub-systems in real-time.
+This can help identify performance bottlenecks, optimize system configuration,
+and improve overall system performance.
+
+Debugging tools: Accel-config provides a set of debugging tools that enable
+users to diagnose and troubleshoot issues with DSA and IAA sub-systems. This
+includes tools for tracing data flow through pipelines, identifying hardware
+faults, and testing individual hardware accelerators.
+
+Scalability: Accel-config is designed to scale to large-scale deployments,
+supporting multiple hardware accelerators and pipelines. It can be integrated
+with existing monitoring and management tools to provide a unified interface
+for managing complex data processing systems.
+
+Overall, Accel-config is a powerful tool for managing and optimizing Intel DSA
+and IAA sub-systems within the Linux kernel. It provides a user-friendly
+interface for configuring and monitoring these sub-systems, enabling users to
+optimize performance for their specific use case.
