+The libraries here fall into four categories corresponding to the four top-level directories:
 
- * Compatible ports of CPython standard libraries. These should be drop-in replacements for the CPython libraries, although many have reduced functionality or missing methods or classes (which may not be an issue for many use cases).
+ * **python-stdlib**: Compatible versions of modules from the [Python Standard Library](https://docs.python.org/3/library/). These should be drop-in replacements for the Python libraries, although many have reduced functionality or missing methods or classes (which may not be an issue for many most cases).
 
- * "Micro" versions of CPython standard libraries with limited compatibility. These can often provide the same functionality, but might require some code changes compared to the CPython version.
+ * **python-ecosys**: Compatible, but reduced-functionality versions of modules from the larger Python ecosystem, for example that might be found in the [Python Package Index](https://pypi.org/).
 
- * MicroPython-specific libraries. These include drivers and other libraries targeted at running Python on hardware or embedded systems.
+* **micropython**: MicroPython-specific modules that do not have equivalents in other Python environments. These are typically hardware drivers or highly-optimised alternative implementations of functionality available in other Python modules.
 
- * MicroPython-on-Unix-specific libraries. These extend the functionality of the Unix port to allow access to operating-system level functionality (which allows more CPython compatibility).
+ * **unix-ffi**: These modules are specifically for the MicroPython Unix port and provide access to operating-system and third-party libraries via FFI.
 
 Usage
 -----
 
 Many libraries are self contained modules, and you can quickly get started by
 copying the relevant Python file to your device. For example, to add the
-`base64` library, you can directly copy `base64/base64.py` to the `lib`
+`base64` library, you can directly copy `python-stdlib/base64/base64.py` to the `lib`
 directory on your device.
 
 Other libraries are packages, in which case you'll need to copy the directory instead. For example, to add `collections.defaultdict`, copy `collections/collections/__init__.py` and `collections.defaultdict/collections/defaultdict.py` to a directory named `lib/collections` on your device.
 
-For devices that have network connectivity (e.g. PYBD, ESP8266, ESP32), they
-will have the `upip` module installed.
-
-```
->>> import upip
->>> upip.install('micropython-base64')
->>> upip.install('micropython-collections.defaultdict')
-...
->>> import base64
->>> base64.b64decode('aGVsbG8sIG1pY3JvcHl0aG9u')
-b'hello, micropython'
->>> from collections import defaultdict
->>> d = defaultdict(int)
->>> d[a] += 1
-```

 Future plans (and new contributor ideas)
 ----------------------------------------
 
 * Provide compiled .mpy distributions.
 * Develop a set of example programs using these libraries.
 * Develop more MicroPython libraries for common tasks.
+* Provide a replacement for the previous `upip` tool.

-Compatibility ranges from:
-
- * Many commonly-used methods and classes are provided with identical runtime semantics.
- * A subset of methods and classes, with identical semantics for most use cases.
- * Additional constants not provided in the main firmware (to keep size down).
- * Stub methods and classes required to make code load without error, but may lead to runtime errors.
