Hacking and contributing

Hacking

• git checkout master; git pull; git checkout -b feature/my_branch
• change code
• add tests for new code
• cargo test --all
• All good? make +rustfmt happy, then submit a Pull Request on github (google for good guides on how github PR's work)

And why not try running your own little grin network? See the local net documentation

Testing

cargo install cargo-cov
