+# Tix
+
+Test your Nix is only ticks.
+
+## Usage
+
+Make a test file:
+
+```mytest.nix
+{ it, ... }:
+[
+    (it "can add numbers" {
+        actual = 2 + 2;
+        expected = 4;
+    })
+    (it "loves big brother" {
+        actual = 2 + 2;
+        expected = 5;
+    })
+]
+```
+
+Add tix as an input to your flake, and use it to build a test output.
+
+```flake.nix
+{
+    description = "My test driven flake";
+
+    inputs = {
+        tix.url = "git+https://git.tristans.cloud/tristan/tix";
+    };
+
+    outpts = {self, tix, ...}: {
+        packages.x86_64-linux.test = tix.run [
+            ./mytest.nix
+        ];
+    };
+}
+```
+
+Then run the generated package.
+
+```sh
+nix run .#test --show-trace
+```
+
+Watch for changes while you are developing your package by adding a new output.
+
+```flake.nix
+tix.watch "nix run .#test | ${pkgs.fx}/bin/fx" "fx";
+```
+
+I am piping the output into `fx` so I can navigate it easier.
+
+`"fx"` is the process name that must be killed before rerunning.
