+# Lambdalib Introduction
 
-Standardized ASIC design libraries
+Lambdalib is a modular hardware abstraction layer that helps decouple hardware design from manufacturing technology and proprietary IP. Lambdalib defines a set of standardized interfaces that are used to instantiate generic cells within a design. Technology specific modules that conform to the Lambdalib interfaces can then be linked at compiler time.
+
+Lambdalib includes the following hardware categories:
+
+| Category                  | Description|
+|---------------------------|------------|
+|[stdlib](stdlib/rtl)       | Standard cells (inv, nand, ff, ...)
+|[ramlib](ramlib/rtl)       | Memory (single port, dual port, fifo, ...)
+|[iolib](iolib/rtl)         | IO cells (bidir, vdd, clamp,...)
+|[padring](padring/rtl)     | Padring generator
+|[vectorlib](vectorlib/rtl) | Vectorized helper library (mux, isolation)
+|[syslib](syslib/rtl)       | Vendor agnostic peripheral interface(uart, i2c,...)
+
+The [Lambdapdk](https://github.com/siliconcompiler/lambdapdk) repository demonstrates implementation of the Lambdalib interfaces across a number of open source process technologies.
+
+Lambdalib has successfully used in multiple tapeouts using [SiliconCompiler](https://github.com/siliconcompiler/siliconcompiler).
