cleaning up the dump command parameters

 provides the commands inside the normal Symfony console and you don't need to
 prepare anything special.
 
-* ``phpcr:workspace:create <name>``: Create the workspace name in the configured repository
-* ``phpcr:register-node-types --allow-update [cnd-file]``: Register namespaces and node types from a "Compact Node Type Definition" .cnd file
-* ``phpcr:dump [--sys_nodes[="..."]] [--props[="..."]] [path]``: Show the node names
-     under the specified path. If you set sys_nodes=yes you will also see system nodes.
-     If you set props=yes you will additionally see all properties of the dumped nodes.
-* ``phpcr:purge``: Remove all content from the configured repository in the
-     configured workspace
-* ``phpcr:sql2``: Run a query in the JCR SQL2 language against the repository and dump
-     the resulting rows to the console.
-
-**TODO:**
-
-* Implement commands for phpcr:import and phpcr:export to import and export the
-    PHPCR document view and system view XML dumps.
-* Implement a simple .cnd parser in PHP and use it to make register-node-types
-    work with all repositories

+To get a list of the available commands, run `bin/phpcr` or set the commands up

 ## Helper Classes
 
 The helper classes provide implementations for basic common tasks to help users
-and implementors of PHPCR. They are all in the namespace PHPCR\Util
+and implementers of PHPCR. They are all in the namespace PHPCR\Util
 
+### PathHelper
 
-### TraversingItemVisitor
+Used to manipulate paths. Implementations are recommended to use this, and
+applications also profit from it. Using `dirname` and similar file system
+operations on paths is not compatible with Microsoft Windows systems, thus you
+should always use the methods in PathHelper.
 
-This ``ItemVisitorInterface`` implementation is a basic implementation of crawling
-a PHPCR tree. You can extend it to define what it should do while crawling the
-tree.
+### NodeHelper
+
+This helper has some generally useful methods like one to generate empty
+`nt:unstructured` nodes to make sure a parent path exists. It also provides
+some useful helper methods for implementations.
+
+### UUIDHelper
 
+This little helper is mainly of interest for PHPCR implementers. It generates
+valid *Universally Unique IDs* and can determine whether a given string is a
+valid UUID.
+We recommend all implementations to use this implementation to guarantee
+consistent behaviour.
 
 ### QOM QueryBuilder
 
@@ -66,25 +65,15 @@ The ``QueryBuilder`` is a fluent query builder with method names matching the
 on top of the QOM factory. It is the easiest way to programmatically build a
 PHPCR query.

 ### Query Object Model Converter
 
 In the PHPCR\Util\QOM namespace we provide, implementation-independant code to
 convert between SQL2 and QOM. ``Sql2ToQomQueryConverter`` parses SQL2 queries
 into QOM . ``QomToSql2QueryConverter`` generates SQL2 out of a QOM.
