 class _MPResterBasic:
     """
-    A new MPRester that supports the new MP API. If you are getting your API key from the new dashboard of MP, you will
-    need to use this instead of the original MPRester because the new API keys do not work with the old MP API (???!).
-    This is a basic implementation for now and features will be added soon. The current implementation is to enable
-    users with simple requirements use the API without having to install additional packages.
-
-    If you are a power user who needs the full functionality, please get the mp-api package instead.
+    This is Pymatgen's own implement of a MPRester that supports the new MP API. If you are getting your API key from
+    the new dashboard of MP, you will need to use this instead of the original MPRester because the new API keys do
+    not work with the old MP API (???!).
+
+    The reason why this class exists is because it is the belief of the pymatgen maintainers that access to the MP API
+    remains a critical part of pymatgen functionality. However, the new mp-api package is written in a way that
+    prevents us from importing the mp-api package because of cyclic dependencies. It is also the opinion of Pymatgen
+    maintainers that the implementation of mp-api is too heavy duty for most users (few care about document models,
+    etc.). Further, this implementation serves as a simple reference for end developers who want to develop their own
+    interfaces to the MP API via the REST urls.
+
+    If you are a power user, feel free to install the mp-api package. All issues regarding that implementation should
+    be directed to the maintainers of that repository and not pymatgen. We will support only issues with regards to
+    our implementation only.
