+## Example
+
+Here's a trivial example:
+
+```rust
+extern crate assert_cli;
+assert_cli::assert_cli_output("echo", &["42"], "42").unwrap();
+```
+
+And here is one that will fail:
+
+```rust,should_panic
+extern crate assert_cli;
+assert_cli::assert_cli_output("echo", &["42"], "1337").unwrap();
+```
+
+this will show a nice, colorful diff in your terminal, like this:
+
+```diff
+-1337
++42
+```
