 ## Basic Usage
 
 Install from PyPI:
+
 ```
-> pip install notebook_shim
+pip install notebook_shim
 ```
+
 This will automatically enable the extension in Jupyter Server.
 
 ## Usage
 
 This project also includes an API for shimming traits that moved from `NotebookApp` in to `ServerApp` in Jupyter Server. This can be used by applications that subclassed `NotebookApp` to leverage the Python server backend of Jupyter Notebooks. Such extensions should *now* switch to `ExtensionApp` API in Jupyter Server and add `NotebookConfigShimMixin` in their inheritance list to properly handle moved traits.
 
 For example, an application class that previously looked like:
+
 ```python
 from notebook.notebookapp import NotebookApp
 
 class MyApplication(NotebookApp):
 ```
+
 should switch to look something like:
+
 ```python
 from jupyter_server.extension.application import ExtensionApp
 from notebook_shim.shim import NotebookConfigShimMixin
 
 class MyApplication(NotebookConfigShimMixin, ExtensionApp):
-```
