 ### Configuring the Context itself
 
-Schemey uses a strategy very similar to marshy for configuration.
+Schemey uses [Injecty](https://github.org/tofarr/injecty) for configuration.
+The default configuration is [here](injecty_config_schemey/__init__.py)
 
-Schemey looks for top level modules starting with the name `schemey_config_*`,
-sorts them by `priority`, and applies them to the default context by invoking their
-`configure` function. [schemey_config_default/__init__.py](schemey_config_default/__init__.py)
-contains the default set of factories.

-For example, for a project named `no_more_uuids`, I may add a file `schemey_config_no_more_uuids/__init__.py`:
