-## Contribution
-
-Accepting Pull Requests is currently paused. We are in the middle of [Decentralizing](https://github.com/tsoding/b/issues/62) this repo. The plan is
-
-1. ~~Create a separate organization for the language.~~
-2. ~~Keep `*x86_64*` and `*aarch64*` codegens in the main repo.~~
-3. Move codegens [6502](./src/codegen/mos6502.rs) (owner [@Miezekatze64](https://github.com/miezekatze64)), [uxn](./src/codegen/uxn.rs) (owner [@deniska](https://github.com/deniska)), [gas-sh4dsp-prizm](https://github.com/tsoding/b/pull/175) (owner [@seija-amanojaku](https://github.com/seija-amanojaku)) to separate repos within the organization and give the owners full admin access to them.
-
-You can still submit PRs in the meantime. Just don't expect them to be reviewed any time soon since decoupling codegens requires extensive refactoring. The PRs will be addressed eventually.
