 # SDKLT
 SDKLT (Logical Table Software Development Kit) is a new, powerful, and feature rich Software Development Kit for Broadcom switches. SDKLT provides a new approach to switch configuration using [Logical Tables](https://github.com/Broadcom-Network-Switching-Software/SDKLT/wiki/What-is-a-Logical-Table%3F).  The [Wiki](https://github.com/Broadcom-Network-Switching-Software/SDKLT/wiki) provides an [overview](https://github.com/Broadcom-Network-Switching-Software/SDKLT/wiki/Architecture-Overview) of SDKLT usage and its achitecture.  An architectural feature summary can be found [here](https://github.com/Broadcom-Network-Switching-Software/SDKLT/wiki/Architecture-Feature-Summary).
