 The best way to use `ohsnap` is to install it using the [Zig Build System](https://ziglang.org/learn/build-system/).  From your project repo root, use `zig fetch` like this:
 
 ```sh
-zig fetch --save "httk://fix<tk>.com"
+zig fetch --save "https://github.com/mnemnion/ohsnap/archive/refs/tags/v0.1.0.tar.gz",

 One of the great advantages of snapshot testing is that it's easy, so `ohsnap`, like the library it's based upon, is intentionally quite simple.  Simple, yet versatile, the latter to a large degree is owed to `pretty`, which can handle anything I've thrown at it, types, unions, you name it.
 
-It's a new library, but no changes to the interface are likely.  It's meant to do one thing, well, and otherwise stay out of the way.  That said, the regex library `mvzr` is pretty new, and so is the added code in `diffz`, so version-bumps to fix any bugs in those can be expected over time.
+It's a new library, but I expect the core interface to remain stable.  It's meant to do one thing, well, and otherwise stay out of the way.  I'm willing to consider suggestions for ways to make `ohsnap` better at what it already does, however.

+That said, the regex library `mvzr` is pretty new, and so is the added code in `diffz`, so version-bumps to fix any bugs in those can be expected over time.  The build system doesn't currently do update checks, so you'll need to check for updates manually, for now.
 
 I hope you enjoy it! Test early, test often, and do it the easy way.
