+# Can I Disc Golf Today?
 A Webtask ready api ready to tell you if the weather looks good for Disc Golfing this weekend.
+
+[Premade example](https://webtask.it.auth0.com/api/run/wt-sharpshark28-gmail_com-0/discGolfWeekend?webtask_no_cache=1)
+
+## How do I generate my own?
+This tool is built on Node/npm/[Webtask](https://webtask.io). Clone this repo locally and within it run:
+
+```
+wt create app.js --secret OPEN_WEATHER_KEY={Your Key}
+```
+
+Where `{Your Key}` is an API key you generate from [OpenWeatherMap](https://openweathermap.org/).
