-The version of the libraries that this depends on can be shown by

+Building
+========
+You can build the library with
 
-    git submodule foreach git rev-parse HEAD
+    git submodule update --init
+	make
 
-Unfortunately Agda's module system does not allow us to automatically
-add these dependencies. So you'll have to make sure you're using
-versions of these libraries that are compatible with this
-project. Since this information is only provided as documentation it
-may also noot be up-to-date so beware.
+The Makefile takes care of using the right dependencies.
+Unfortunately I have not found a way to automatically inform
+`agda-mode` that it should use these dependencies. So what you can do
+in stead is to copy these libraries to a global location and then add
+them system wide:
 
-You can let Agda know about these libraries by appending them to your global
-libraries file like so: (NB!: There is a good reason this is not in a
-makefile. So please verify that you know what you are doing, you probably
-already have standard-library in you libraries)
+    mkdir -p ~/.agda/libs

-Anyways, assuming you have this set up you should be good to go.
