This Quickstart will help you get your KRL programming environment set up and working. 

The old Quickstart for SquareTag is still available. 

Learning Objectives

After completing this Quickstart lesson, you will:

...

1. Create a git repo for your KRL rulesets and put it on Github. You can create a different repo for each ruleset if you like or create one repo and put multiple rulesets in it. 

2. Create  file in your ruleset repo called hello.krl and put the following in it:

   Code Block
   language javascript theme Confluence language javascript
   ruleset hello_world { meta { name "Hello World" description << A first ruleset for the Quickstart >> author "Phil Windley" logging on sharing on provides hello } global { hello = function(obj) { msg = "Hello " + obj msg }; } rule hello_world { select when echo hello send_directive("say") with something = "Hello World"; } }

3. Use one of the methods in Tips for Developers to validate (parse) your ruleset.

   Info
   Installing and using the KRL command line parser can be a real time saver if you're going to be writing several rulesets. Checking in and trying to execute rulesets that don't parse is one of the primary frustrations of beginning KRL developers.

4. Check your ruleset into Github.
