 # How to use this image
 
-## Start a Lein/Clojure instance in your app
+## Build tools
 
-Since the most common way to use Clojure is in conjunction with [Leiningen (`lein`)](http://leiningen.org/), this image assumes that's how you'll be working. The most straightforward way to use this image is to add a `Dockerfile` to an existing Leiningen/Clojure project:
+Clojure has three major approaches to building and running projects:
+
+1.	[leiningen](https://leiningen.org)
+	1.	The oldest and probably most common tool
+2.	[boot](http://boot-clj.com)
+	1.	An alternative approach that solves similar problems as leiningen
+3.	[tools-deps](https://clojure.org/guides/deps_and_cli)
+	1.	A more recent official tool for some of the lein/boot use cases
+
+There are variants of this image for all three of these tools and their respective releases. The most basic form of these tags is:
+
+1.	`clojure:lein`
+2.	`clojure:boot`
+3.	`clojure:tools-deps`
+
+But you can also append a hyphen and the version of that tool you'd like to use. For example, for lein 2.8.1 you can use this image: `clojure:lein-2.8.1`.
