Picocrypt/src/README.md

Note: Picocrypt can use the reedsolo pip package itself, but it is very slow because it's pure Python. It is recommended to compile a Python extension (.pyd/.so) for reedsolo, and name it creedsolo (ie. creedsolo.pyd or creedsolo.so). Make sure to include the extension in the same directory as Picocrypt.py. The Windows executable already bundles creedsolo.pyd, but for Linux, you'll have to build the Python extension yourself if you want better speeds. Building the extension is not necessary if you don't intend on using the Reed-Solomon feature, or if you are okay with speeds ~1MB.
