 Run with input from stdin:
+
 ```sh
-echo "(+ 1 2)" | cargo run && ./output ; echo $?
+echo "fn main() { print(42); }" | cargo run && ./output
 ```
+
 Run with specified input path, without specifying an output path:
+
 ```sh
-cargo run -- example.jj && ./example ; echo $?
+cargo run -- example.jj && ./example
 ```
+
 Run with specified input path and specified output path:
+
 ```sh
-cargo run -- input.jj -o output && ./output ; echo $?
+cargo run -- input.jj -o output && ./output
