docs/README.txt

 The documentation of tvm is generated with recommonmark and sphinx.
 
+- A hosted version of doc is at http://docs.tvmlang.org
 - pip install sphinx>=1.5.5 sphinx-gallery sphinx_rtd_theme matplotlib Image recommonmark
 - Build tvm first in the root folder.
 - To build locally, you need to enable USE_CUDA, USE_OPENCL, LLVM_CONFIG in config.mk and then type "make html" in this folder.

+Frequently Asked Questions
+==========================
+This document contains frequently asked questions.
+
+How to Install
+--------------
+See [Installation](how_to/install.md)
+
+TVM's relation to XLA
+---------------------
+They has different abstraction level.
+XLA is a higher level tensor algebra DSL, the system defines codegen and loop transformation
+rules for each kernels. TVM is an low level array index based DSL that give the loop transformation
+primitives to the user. In terms of design philosophy, TVM aims to be directly used by developers
+and provide general support for different framework via DLPack.
+See also [This Issue](https://github.com/dmlc/tvm/issues/151)
+
+TVM's relation to libDNN cuDNN
+------------------------------
+TVM can incoporate these library as external calls. One goal of TVM is to be able to
+generate high performing kernels. We will evolve TVM an incremental manner as
+we learn from the technics of manual kernel crafting and add these as primitives in DSL.
