+## Configuration
+
+*flags*
+
+-   --kind/-k: The kind of lottery.
+-   --count/-c: Number of draws to generate.
+-   --count-prompt/-C: Prompt for the number of draws to generate.
+> Note. If both --count and --count-prompt are passed the count prompt will win.
+
+*environment variables*
+
+```bash
+#!/usr/bin/env bash
+
+export LOTTERY_KIND=lotto
+export LOTTERY_COUNT=3
+export LOTTERY_COUNT_PROMPT=false
+```
+
+## Use
+
+Run with the selection prompt without prompting for a count:
+
+```console
+lottery
+```
+
+Run with the selection prompt but also prompt for a count:
+
+```console
+lottery --count-prompt
+```
+
+Run with the selection prompt but pass in the count directly:
+
+```console
+lottery --count=4
+```
+
+Run a single draw directly:
+
+```console
+lottery -k=euromillions 
+```
+
+Run multiple draws directly:
+
+```console
+lottery -k=euromillions -c=3
+```
