If you have any troubles installing gmp on your Apple M1 computer, here’s a list of potential solutions.
For VSCode support:
Download cairo-0.6.2.vsix
from https://github.com/starkware-libs/cairo-lang/releases/tag/v0.6.2
And run:
code --install-extension cairo-0.6.2.vsix

Install the Nile dev environment and then run install
to get the Cairo language, a local network, and a testing framework.
pip3 install cairo-nile
nile install
Usage
Compile the contracts
nile compile

Extending Cairo contracts
There's no clear contract extensibility pattern for Cairo smart contracts yet. In the meantime the best way to extend our contracts is copypasting and modifying them at your own risk. Remember this contracts are still under development and they have not gone through any audit or security review whatsoever.
