 Installation
 ============
 
-Percy is a header-only library. As such, no build steps are required to start
-using it. Simply add ${PERCY_ROOT}/include to your compiler's include path and
-you're good to go. However, if you want to run the tests, you'll need to build
-some binaries. 
+If you want to run `phyLS`, you'll need to build some binaries. A modern compiler is required to build the libraries. The build instructions depend on your operating system. We are now only support Unix-like operating systems, compiled only successfully with Clang 6.0.1, Clang 12.0.0, GCC 7.3.0, and GCC 8.2.0.
 
-The build instructions depend on your operating system. On Unix-like operating
-systems you will need either g++ (at least version 4.9.0) or clang++ (at least
-version 3.5.0). On Windows you can build using Visual Studio. (NOTE: This has
-been tested only with Visual Studio 2017.) Once those requirements are met, run
-the following commands to build and run the tests:
+Once those requirements are met, run the following commands to build and run the `phyLS`:
 
 .. code-block:: bash
 
-    git clone --recurse-submodules https://github.com/whaaswijk/percy.git
-    cd percy
+    git clone --recursive https://github.com/panhongyang0/phyLS.git
+    cd phyLS
     mkdir build
     cd build
-    cmake .. -DPERCY_TEST=ON # Only on Unix
-    cmake -DPERCY_TEST=ON -G "Visual Studio 15 2017" .. # On Windows
-    make # Only on Unix
-    make test # Only on Unix
+    cmake ..
+    make
+    ./bin/phyLS
 
-On Unix systems this will build and run the test suite. On Windows it will
-generate a solution file which allows you to build and run the tests using
-Visual Studio.
