# Objective
- Document that the error codes will be rendered on the bevy website (see bevyengine/bevy-website#216)
- Some Cargo.toml files did not include the license or a description field
## Solution
- Readme for the errors crate
- Mark internal/development crates with `publish = false`
- Add missing license/descriptions to some crates
- [x] merge bevyengine/bevy-website#216
# Objective
- Improve error descriptions and help understand how to fix them
- I noticed one today that could be expanded, it seemed like a good starting point
## Solution
- Start something like https://github.com/rust-lang/rust/tree/master/compiler/rustc_error_codes/src/error_codes
- Remove sentence about Rust mutability rules which is not very helpful in the error message
I decided to start the error code with B for Bevy so that they're not confused with error code from rust (which starts with E)
Longer term, there are a few more evolutions that can continue this:
- the code samples should be compiled check, and even executed for some of them to check they have the correct error code in a panic
- the error could be build on a page in the website like https://doc.rust-lang.org/error-index.html
- most panic should have their own error code
