+TI Tiva TM4C129 example
+=======================
+
+This directory contains a Mongoose example CCS project for Tiva TM4C129.
+
+It targets the [Crypto Connected LaunchPad](http://www.ti.com/tool/ek-tm4c129exl) dev board.
+
+You will need CCS 6+ with Tiva support and TivaWare SDK installed.
+
+TivaWare should be installed under `${TI_PRODUCTS_DIR}/TivaWare_C_Series-2.1.3.156`,
+which is usually `C:\TI\TivaWare_C_Series-2.1.3.156` on Windows.
+
+If you have a different version installed, please edit the `SDK_ROOT` path
+variable under `Project -> Properties -> Resource -> Linked Resources`.
