# sha3.py
-Access `libsha3.so` functions via Python ctypes module and compare
-libsha3.so output against hashlib output.
+Load top-level `libsha3.so` in [Python][], calculate the digest of
+hard-coded sample data with several `libsha3.so` functions and their
+[hashlib][] equivalents, then print the results to standard output in
+[CSV][] format.
+
+## Usage
+
+Run `make` in the top-level directory to build the `libsha3.so` shared
+object, then run the example script like so:
+
+ > python3 ./sha3.py
+ algo,source,digest
