 # Ziffers for Python 3.10+
 
-This repo is hosting an attempt at porting the [Ziffers](https://github.com/amiika/ziffers) numbered musical notation to Python 3.10+. This library is using [parsimonious](https://github.com/erikrose/parsimonious) for PEG parsing.
+This repo is hosting experimental parser for the [Ziffers](https://github.com/amiika/ziffers) numbered musical notation to Python 3.10+. This library is using lark lalr-1 parser and ebnf PEG for parsing the notation.
 
+## Supported environments
+
+Ziffers python supports following live coding and computer-aided composition environments:
+
+* [Sardine](https://github.com/Bubobubobubobubo/sardine)
+* [Music21](https://github.com/cuthbertLab/music21)
