 Generators
 ==========
 
+Generators are specific components that provide the information of dependencies calculated by Conan in a suitable format for a build system.
+They normally provide Conan users with a *conanbuildinfo.XXX* file that can be included or injected to the specific build system. The file
+generated contains information of dependencies in form of different variables and sometimes function helpers too.
