+## Stack
+
+### Prerequisites
+
+* [`stack 3.1.1+`](https://docs.haskellstack.org/en/stable/)
+
+Like `cabal` and `ghc`, `stack` can be installed with [`ghcup`](https://www.haskell.org/ghcup/).
+
+### Build Pacer
+
+Once you have `stack`, `pacer` can be built with `stack build` or installed globally (i.e. `~/.local/bin/pacer`) with `stack install`.
+
 ## Nix
