 ### Installation
 
-#### PATH setup
+At the moment, Herm's can only be installed via [stack](https://docs.haskellstack.org/en/stable/README/) or [cabal](https://www.haskell.org/cabal/), but standalone binaries are in the works!
 
-Firstly, make sure that the following is added to your PATH:
+If you're interested developing/hacking Herm's instead of just using it, see [Contributing.md](Contibuting.md) instead.

 - `defaultUnit` : The default unit system to show recipes in. Options: `Imperial`, `Metric`, `None`. Setting to `None` will simply show recipes in whatever unit system they're stored in.
 - `defaultServingSize` : Default serving size to calculate when showing recipes. Can be any non-negative integer; set to `0` for no default. This can be useful when you're always cooking for the same number of people!
-- `recipesFile` : The recipes file and relative location. Make sure the file already exists by running `touch FILENAME` before running Herm's or it will throw a fit. This option currently supports relative location, as well; if your data directory is `~/herms/data`, for example, and you want a recipe file in your home directoy called `~/GrandmasHugeCookbook.herms`, set this option to `"../../GrandmasHugeCookbook.herms"`.
+- `recipesFile` : The recipes file to us.
