+Installation
+============
+
+Before installing `sherpa`_, we assume you have installed:
+
+- `PyTorch`_
+- `k2`_
+- `kaldifeat`_
+
+You can use the following commands to install `sherpa`_:
+
+.. code-block:: bash
+
+   git clone http://github.com/k2-fsa/sherpa
+   cd sherpa
+   python3 setup.py bdist_wheel
+   ls -lh dist
+   pip install ./dist/k2_sherpa*.whl
+
+.. caution::
+
+   Please don't use ``python3 setup.py install``. Otherwise, you won't get
+   `sherpa`_ related binaries installed, such as ``sherpa-offline`` and
+   ``sherpa-online``.
+
+To uninstall `sherpa`_, please use
+
+.. code-block:: bash
+
+   pip uninstall k2-sherpa
+
+To test that you have installed `sherpa`_ successfully, you can run the
+following commands:
+
+.. code-block:: bash
+
+   sherpa-version
+
+   sherpa-offline --help
+   sherpa-online --help
+   sherpa-online-microphone --help
+
+   sherpa-offline-websocket-server --help
+   sherpa-offline-websocket-client --help
+
+   sherpa-online-websocket-server --help
+   sherpa-online-websocket-client --help
+   sherpa-online-websocket-client-microphone --help
+
+If you have any issues about the installation, please create an issue
+at the following address:
+
+  `<https://github.com/k2-fsa/sherpa/issues>`_
+
+.. hint::
+
+   If you have a `WeChat <https://www.wechat.com/>`_ account, you can scan
+   the following QR code to join the WeChat group of next-gen Kaldi to get
+   help.
+
+   .. image:: pic/wechat-group-for-next-gen-kaldi.jpg

+    :align: center
+    :alt: WeChat group of next-gen Kaldi
+
+
+Installation for advanced users/developers
+------------------------------------------
+
+As an advanced user/developer, you can use the following method to
+install `sherpa`_:
+
+
+.. code-block:: bash
+
+   git clone http://github.com/k2-fsa/sherpa
+   cd sherpa
+   mkdir build
+   cd build
+   cmake ..
+   make -j

+C++ APIs
+========
+
+We provide C++ APIs for non-streaming ASR
+in
+`a single header file <https://github.com/k2-fsa/sherpa/blob/master/sherpa/cpp_api/offline_recognizer.h>`_.
+
+`<https://github.com/k2-fsa/sherpa-torch-cpp-makefile-example>`_
+gives an example of how to use the APIs to decode wave files.
+
+.. hint::
+
+  You can find more examples in
+  `<https://github.com/k2-fsa/sherpa/tree/master/sherpa/cpp_api>`_
+
+The content of the `Makefile <https://github.com/k2-fsa/sherpa-torch-cpp-makefile-example/blob/master/Makefile>`_
+from the above repository is given below:
+
+.. code-block:: makefile
+
+  sherpa_install_dir := $(shell python3 -c 'import os; import sherpa; print(os.path.dirname(sherpa.__file__))')
+  sherpa_cxx_flags := $(shell python3 -c 'import os; import sherpa; print(sherpa.cxx_flags)')
+
+  $(info sherpa_install_dir: $(sherpa_install_dir))
+  $(info sherpa_cxx_flags: $(sherpa_cxx_flags))
+
+  CXXFLAGS := -I$(sherpa_install_dir)/include
+  CXXFLAGS += -Wl,-rpath,$(sherpa_install_dir)/lib
+  CXXFLAGS += $(sherpa_cxx_flags)
+  CXXFLAGS += -std=c++14

+    $(CXX) $(CXXFLAGS) -o $@ $< $(LDFLAGS)
+
+  .PHONY: clean
+  clean:
+    $(RM) test_decode_files

+Basically, you only need to specify the following stuff to use the non-streaming
+ASR APIs:
+
+- The path to find the header file. You provide:
+
+  .. code-block:: makefile
+
+    CXXFLAGS := -I$(sherpa_install_dir)/include
+
+- The library to link to. You provide:
+
+  .. code-block:: makefile
+
+    LDFLAGS := -L $(sherpa_install_dir)/lib -lsherpa_offline_recognizer
+
+- The CXX flags used to compile ``sherpa``. You provide:
+
+  .. code-block:: makefile
+
+    CXXFLAGS += $(sherpa_cxx_flags)
+
+  .. hint::
+
+    This one is important. For instance, if ``sherpa`` was compiled with
+    ``-D_GLIBCXX_USE_CXX11_ABI=0`` on Linux, you will get link errors like
+    the below one if you don't use this option in your project.
+
+    .. code-block::
+
+      test_decode_files.cc:(.text+0x149): undefined reference to
+      `sherpa::OfflineRecognizer::OfflineRecognizer(std::__cxx11::basic_string<char,
+      std::char_traits<char>, std::allocator<char> > const&, std::__cxx11::basic_string<char,
+      std::char_traits<char>, std::allocator<char> > const&, sherpa::DecodingOptions const&, bool, float)'
