 If you want it to be installed in another place just run `make` and copy the file to where you want it.
 
 ## Usage
+### Config file
 In order to create a MakeGen configuration file use the following command:
 
-    makegen --conf
+    makegen conf gen prompt
 
 This will prompt you with all the needed configurations in order to create a Makefile which will compile your code.
 When this is done it will create a file called `makegen.conf` which contains all relevant data for MakeGen to create a Makefile.
 
+If you want to change your config you can modify the makegen.conf file or use makegens config command line interface.
+To see the possible changes you can do see the help file by entering:
+
+    makegen conf
+
+### Compiling
 After that simply compile your code with:
 
     makegen

 Since MakeGen generates include dependencies in your Makefile it can cause the Makefile to get very cluttered.
-In order to make it less cluttered you can run `makegen --simple` which will generate (and run) a Makefile without header file dependencies.
