+# Global Increment
+
+This program creates a persisted sequence that increments every time it is
+called, useful when you need to call the same command over and over and need to
+pass an ever-increasing number to it. Takes an optional positional argument that
+acts as a key, allowing multiple sequences to be used.
+
+## Usage
+
+```bash
+incr [KEY]
+```
+
+## Installation
+
+Copy the `incr` file somewhere in your `PATH`. Needs [Deno][https://deno.com]
+installed.
