+# Aborting on panic
+
+![Minimum Rust version: 1.10](https://img.shields.io/badge/Minimum%20Rust%20Version-1.10-brightgreen.svg)
+
+By default, Rust programs will unwind the stack when a `panic!` happens. If you'd prefer an
+immediate abort instead, you can configure this in `Cargo.toml`:
+
+```toml
+[profile.debug]
+panic = "abort"
+
+[profile.release]
+panic = "abort"
+```
+
+Why might you choose to do this? By removing support for unwinding, you'll
+get smaller binaries. You will lose the ability to catch panics. Which choice
+is right for you depends on exactly what you're doing.
