+This is an example of multi-module project gradle configuration.
+
+### Hierarchical and Flat Project Layouts
+
+In multi-module project `settting.gradle` is required to specify module location.
+ ( While for simple project you can play with build using `gradle -b` option
+ to specify what `build.gradle` to use, e.g. `gradle -b second.gradle`,
+ for multi-module project `settings.gradle` is the only way. )
+
+hierarchical project layout
+
+	- app
+		build.gradle
+	- module
+		build.gradle
+	build.gradle
+	settings.gradle
+	
+
+flat project layout
+
+	- app
+		build.gradle
+	- module
+		build.gradle
+	- parent	
+		build.gradle
+		settings.gradle
+
+So with flat project layout you can achieve different composition for a build, e.g.   
+
+	- app
+		build.gradle
+	- module
+		build.gradle
+	- parent	
+		build.gradle
+		settings.gradle
+	- second	
+		build.gradle
+		settings.gradle
+
+However when executing build from
+[command line](http://www.gradle.org/docs/current/userguide/gradle_command_line.html)
+for flat project layout, you may must to specify
+location of `settings.gradle` if it is not in current folder, e.g. when in `app` folder 
+
+	gradle build -c ../parent/settings.gradle
+	
+_I think default file name should be `components.gradle` or other start with c._
+_Besides settings is t0o general word._
