@@ -6,36 +6,13 @@ There is a huge list of modules available in the imag core distribution.
 From a naming perspective, we do not differ between low-level and high-level
 modules. Some of the modules shipped with imag cover core functionality such as
 linking, tagging or references to files outside of the store or even the store
-interface itself (which by the way shouldn't be used by the end-user at all).
+interface itself.
 Others cover things like diary, notes, wiki or bookmarks.
+These are also called "domains".
 
 We try really hard to offer a consistent commandline user interface over all of
 these modules.
 
 The following sections describe each module in detail, including its purpose and
-its provided backends.
-
-A backend is simply an external tool imag might be able to use.
-For example, the `imag-todo` module offers a `taskwarrior` interface, so imag
-itself does not cover anything which has to do with todo management, but lets
-you continue using `taskwarrior` for that (which does a really good job).
-So what does the `imag-todo` module do?
-Well, it offers you ways to track tasks created in `taskwarrior` and putting
-files which can be used as references to tasks then.
-For example, if you create a task in `taskwarrior`, you end up with an UUID for
-this task.
-imag stores this UUID in a store entry and you are now able to `imag-link` this
-file with other files in the store.
-This way you can link `taskwarrior` tasks with other data (of course,
-`imag-todo` offers some more commands, for searching tasks and so on).
-
-But what if you do not like `taskwarrior`?
-That's what backends are for.
-The goal of imag is to provide backends for not just one tool which implements a
-PIM aspect, but for many.
-So you can change the configuration for `imag-todo` to not use `taskwarrior` but
-some other todo tool.
-
-(This is all hypothetical by now because these things are not yet implemented.
-Anyhow, we aim for exactly what is described above)
