-    subclass should hold all data and functions that are independent from the specific

+    \section1 Handling External Modifications
-    was designed to work with.
+
+    You can implement IDocument and register instances in DocumentManager to
+    let it handle external modifications of a file. When the file specified with
+    filePath() has changed externally, the DocumentManager asks the
+    corresponding IDocument instance what to do via reloadBehavior(). If that
+    returns \c IDocument::BehaviorAsk, the user is asked if the file should be
+    reloaded from disk. If the user requests the reload or reloadBehavior()
+    returns \c IDocument::BehaviorSilent, the DocumentManager calls reload()
+    to initiate a reload of the file from disk.
+
+    Core functions: setFilePath(), reload(), reloadBehavior().
+
+    If the content of the document can change in \QC, diverging from the
+    content on disk: isModified(), save(), isSaveAsAllowed(),
+    fallbackSaveAsPath(), fallbackSaveAsFileName().
+
+    \section1 Editor Document
+
+    The most common use case for implementing an IDocument subclass is as a
+    document for an IEditor implementation. Multiple editor instances can work
+    on the same document instance, for example if the document is visible in
+    multiple splits simultaneously. So the IDocument subclass should hold all
+    data that is independent from the specific IEditor instance, for example
+    the content and highlighting information.
+
+    Each IDocument subclass is only required to work with the corresponding
+    IEditor subclasses that it was designed to work with.
+
+    An IDocument can either be backed by a file, or solely represent some data
+    in memory. Documents backed by a file are automatically added to the
+    DocumentManager by the EditorManager.
+
+    Core functions: setId(), isModified(), contents(), setContents().
+
+    If the content of the document is backed by a file: open(), save(),
+    setFilePath(), mimeType(), shouldAutoSave(), setSuspendAllowed(), and
+    everything from \l{Handling External Modifications}.
+
+    If the content of the document is not backed by a file:
+    setPreferredDisplayName(), setTemporary().
