+=== List all dependencies
+
+There are several helpful tools in the built-in `:deps` alias to explore the full set of transitive deps.
+
+To https://clojure.github.io/tools.deps.cli/clojure.tools.deps.cli.api-api.html#clojure.tools.deps.cli.api/list[list the full set of all the deps] included on your classapth, use `clj -X:deps list`. For example in the `hello-world` application at the top of this guide, you would see something like this:
+
+[source,shell]
+----
+% clj -X:deps list
+clojure.java-time/clojure.java-time 1.1.0  (MIT)
+org.clojure/clojure 1.11.1  (EPL-1.0)
+org.clojure/core.specs.alpha 0.2.62  (EPL-1.0)
+org.clojure/spec.alpha 0.3.218  (EPL-1.0)
+time-lib/time-lib ../cli-getting-started/time-lib
+----
+
+The full set of transitive dependencies used by your application is listed in alphabetical order with version and license. See the api docs for additional printing options.
+
+If you want to understand the https://clojure.github.io/tools.deps.cli/clojure.tools.deps.cli.api-api.html#clojure.tools.deps.cli.api/tree[tree structure of your dependencies] and how version selection choices were made, use `clj -X:deps tree`:
+
+[source,shell]
+----
+% clj -X:deps tree
+org.clojure/clojure 1.11.1
+  . org.clojure/spec.alpha 0.3.218
+  . org.clojure/core.specs.alpha 0.2.62
+time-lib/time-lib /Users/alex.miller/tmp/cli-getting-started/time-lib
+  . clojure.java-time/clojure.java-time 1.1.0
+----
+
+There were no version selections made here, but see https://clojure.org/reference/dep_expansion#_tree_printing[the docs] for more on how the choices are explained in the tree.
+
+Both of these helper functions take an optional `:aliases` argument if you wish to examine the dependency list or tree with one or more aliases applied, such as `clj -X:deps list '[:alias1 :alias2]'`.
