+Our CI enforces [clippy's](https://github.com/rust-lang/rust-clippy) default linting
+[settings](https://rust-lang.github.io/rust-clippy/rust-1.39.0/index.html).
+This includes all lint groups except for nursery, pedantic, and cargo in addition to allowing the following lints:
+`erasing_op`, `never_loop`, `if_same_then_else`.
+
+If you use rustup, feel free to lint locally, otherwise you can just push to CI for automated linting.

+```bash
+rustup component add clippy
+cargo clippy

+C/C++ Bindings
+--------------
+
+You can learn more about the C/C++ bindings that are made available by reading the
+[C/C++ Bindings README](lightning-c-bindings/README.md). If you are not using the C/C++ bindings,
+you likely don't need to worry about them, and during their early experimental phase we are not
+requiring that pull requests keep the bindings up to date (and, thus, pass the bindings_check CI
+run). If you wish to ensure your PR passes the bindings generation phase, you should run the
+`genbindings.sh` script in the top of the directory tree to generate, build, and test C bindings on
+your local system.
