 ========================
 
 The `brilirs` directory contains a fast Bril interpreter written in [Rust][].
-It is a drop-in replacement for the [reference interpreter](interp.md) that prioritizes speed over completeness and hacakability.
+It is a drop-in replacement for the [reference interpreter](interp.md) that prioritizes speed over completeness and hackability.
 It implements [core Bril](../lang/core.md) and the [SSA][], [memory][], and [floating point][float] extensions.
 
 Read [more about the implementation][blog], which is originally by Wil Thomason and Daniel Glus.
 
 Install
 -------
-To use `brilirs` you will need to [install Rust](https://www.rust-lang.org/tools/install) and add the nightly channel with `rustup toolchain install nightly`. Use `echo $PATH` to check that `$HOME/.cargo/bin` is on your [path](https://unix.stackexchange.com/a/26059/61192).

 In the `brilirs` directory, build the interpreter with:
 
-    cargo +nightly install --path .
+    cargo install --path .
 
 Run a program by piping a JSON Bril program into it:
