## Before hacking on Cargo
We encourage people to discuss their design before hacking on code. Typically,
you [file an issue] or start a thread on the [internals forum] before submitting
a pull request.
Please read [the process] of how features and bugs are managed in Cargo.
**Only issues that have been explicitly marked as [accepted] will be reviewed.**
