 I thought it was briefly worth discussing his note on learning an approach vs using a tool.
 
 I think that learning an approach is valuable, this module would not exist without the
-example given by `cluegen`. It also wouldn't exist if I hadn't needed to extend `cluegen`
-for some basic features (try using `Path` default values with `cluegen`).
+example given by `cluegen`.
+
+However, what I foundn was that in essentially every case where I wanted to use 
+these generating tools, I needed to modify them - often significantly. 
+It quickly became easier to just create my own tool and upload it as a package.
+
+For example, `cluegen` has a few subtle "exercises for the reader". It needs extending
+and fixing for some use-cases.
+   * Default values that are not builtins need to be passed as part of the globals 
+     dict to `exec`.
+   * No support for mutable defaults.
+   * Subclass methods will be overwritten if they call a cluegen method that has not been
+     generated via `super().methodname(...)`
+   * `inspect.signature(cls)` does not work if `cls.__init__` has not already been generated.
+     (I think this is actually a bug in inspect).
+   * Need an extra filter to support things like `ClassVar`.
 
 In the general spirit though, this module intends to provide some basic tools to help 
-build your own custom class generators.
+create your own customized boilerplate generators.
 The generator included in the base module is intended to be used to help 'bootstrap' a 
 modified generator with features that work how **you** want them to work.
 
-The `prefab` module is the more fully featured powertool *I* built with these tools. 
-However, much like a prefabricated building, it may not be what you desire.
+The `prefab` module is the more fully featured tool that handles the additional cases *I*
+needed.
