+-- ## FAQ
+--
+-- You can enter the project directory firstly before building project.
+--
+--   $ cd projectdir
+--
+-- 1. How to build project?
+--
+--   $ xmake
+--
+-- 2. How to configure project?
+--
+--   $ xmake f -p [macosx|linux|iphoneos ..] -a [x86_64|i386|arm64 ..] -m [debug|release]
+--
+-- 3. Where is the build output directory?
+--
+--   The default output directory is `./build` and you can configure the output directory.
+--
+--   $ xmake f -o outputdir
+--   $ xmake
+--
+-- 4. How to run and debug target after building project?
+--
+--   $ xmake run [targetname]
+--   $ xmake run -d [targetname]
+--
+-- 5. How to install target to the system directory or other output directory?
+--
+--   $ xmake install
+--   $ xmake install -o installdir
+--
+-- 6. Add some frequently-used compilation flags in xmake.lua
+--
+-- @code
+--    -- add debug and release modes
+--    add_rules("mode.debug", "mode.release")
