 ## Quickstart
 
+Create a new directory and require the project using composer:
+
+```text
+$ mkdir mylisp
+$ cd mylisp
+$ composer require "maddy83/madlisp dev-master"
+```
+
+Use the `vendor/bin/madlisp` executable to start the interpreter. Start the REPL with the `-r` option:
+
+```text
+$ vendor/bin/madlisp -r
+>
+```
+
+You can evaluate Lisp code interactively inside the REPL:
+
+```text
+> (+ 1 2 3)
+6
+```
+
+Alternatively you can evaluate a file that contains Lisp code:
+
+```text
+$ echo "(+ 1 2 3)" > mylisp.mad
+$ vendor/bin/madlisp mylisp.mad
+6
+```
