+###### Set the default configuration value
+
+This interface is introduced from version 2.2.2 to set the default configuration value in xmake.lua.
+
+Many previous configurations, including the build toolchain, build directory, etc. 
+We can only be configured by `$xmake f --name=value`. If we want to write a default value in xmake.lua, we can use the following method:
+
+```lua
+set_config("name", "value")
+set_config("buildir", "other/buildir")
+set_config("cc", "gcc")
+set_config("ld", "g++")
+```
+
+However, we can still modify the default configuration in xmake.lua by `$xmake f --name=value`.

 #### Project Target
 
 We can use `target("test")` to define a project target named "test", each target generates an executable program, a static library, or a dynamic library.
