Welcome to Joypy Wiki
Most of the documentation is in the /docs directory: https://osdn.net/projects/joypy/scm/hg/Joypy/tree/tip/docs/
They are Jupyter notebooks (there are instructions in the README for running them) and I have converted them to Markdown and HTML formats for easier viewing without Jupyter. Eventually I would like to migrate some of the information in the notebooks to this wiki.
(For the wiki itself , you can find grammar and other documents on Sidebar links or Wiki guide in OSDN Docs-en project.)
