 ## Add
 
+**This project is a component of the [mulle-core](//github.com/mulle-core/mulle-core) library. As such you usually will *not* add or install it
+individually, unless you specifically do not want to link against
+`mulle-core`.**
+
+
+### Add as an individual component
+
 Use [mulle-sde](//github.com/mulle-sde) to add MulleObjC to your project:
 
 ``` sh
-mulle-sde add github:/
+mulle-sde add github:mulle-objc/MulleObjC
 ```
 
 To only add the sources of MulleObjC with dependency
 sources use [clib](https://github.com/clibs/clib):
 
 
 ``` sh
-clib install --out src/ /
+clib install --out src/mulle-objc mulle-objc/MulleObjC
 ```
 
-Add `-isystem src/` to your `CFLAGS` and compile all the sources that were downloaded with your project.
