+OpenSWR-Mesa
+============
+
+Overview
+--------
+
+This is repository of the integration work combining the high
+performance, highly scalable core SWR rasterizer with Mesa. A more
+complete introduction and discussion towards upstreaming to the Mesa
+project can be found on the mesa-dev mailing list.
+
+Notes
+-----
+
+* SWR is set as the default software renderer. Use
+GALLIUM_DRIVER=llvmpipe to switch to Mesa's standard rasterizer. This
+particular change is to make it easier for people evaluating OpenSWR,
+and will not be upstreamed.
+
+* LLVM-3.6 is required.
+
+* To build SWR with autoconf, include the following in the config
+line: "--with-gallium-drivers=swr --enable-swr-native".
+
+* Build defaults to AVX2; for a version to run on AVX build with
+ "--with-swr-arch=AVX".
+
+* To build SWR with SCons, nothing needs to be done - it is built by
+ default.
+
+* Code for the driver is in src/gallium/drivers/swr
+
+* Code for the rasterizer is in src/gallium/drivers/swr/rasterizer
