 Overview
 --------
 
@@ -41,20 +26,76 @@ The design principles of this library are as follows:
    itself, anyway (see e.g. Data). A notable exception of the
    no-virtuals rule is the use of abstract classes to cover
    C-callbacks.
+6. Use of STL containers for improved memory management and
+   dealing with lists.
+7. Complete abstraction of the C-API so "gpgme.h" should not
+   be needed in your project using GpgME++.
+8. Abstraction of GnuPG's edit-key interface by prepared
+   Editinteractor classes.
+
+GpgMEpp was originally developed as part of the KDEPIM community.
+
+Usage
+-----
+
+The usage pattern of GpgMEpp closely follows GPGMEs core usage
+pattern so the documentation for GPGME itself provides a good
+way to start.
+
+The context structure in GPGME is mapped to a Context object in
+GpgMEpp. Additional convienience code provides Data objects and
+a Dataprovider interface that can be used to implement GPGME's
+data with any subclass by implementing the right callbacks.
 
-GpgMEpp was originally developed as part of the KDEPIM community
-in KDE 4 it was part of kdepimlibs/gpgme++ for KF5 Gpgmepp was
-renamed to KF5GpgMEpp and moved into it's own repository.
+EditInteractor subclasses provide ready to use classes for
+common --edit-key tasks. You can implement your own editinteractor
+classes by implementing the EditInteractor interface and using
+your subclass as an interactor in the edit function.
+
+Example to set the ownertrust of a key:
+
+    /* Create an edit interactor */
+    EditInteractor *ei = new GpgSetOwnerTrustEditInteractor(Key::Ultimate);
+    /* Obtain a Context */
+    Context *ctx = Context::createForProtocol(Protocol::OpenPGP);
+    /* Create an in memory data object */
+    Data data;
+    /* Start the edit on some key previously obtained. */
+    Error e = ctx->edit(key, std::unique_ptr<EditInteractor>(ei), data);
+    /* Errors provide boolean comparision */
+    if (!e)
+        ...
+    /* Delete the context */
+    delete ctx;
+
+Examples / Tests
+----------------
+
+GpgMEpp is tested through the Qt API. You can refer to the
+tests in qt/tests for examples of usage or refer to
+the actual QGpgME*Job.cpp implementations which rely
+on GpgMEpp and should cover most use cases.
