-## Instructions
+## Curried? Lazy?
+
+Currying consists in convert **one function** that takes **multiple arguments** into **multiple functions** that each take a **single argument**.
+
+*WIP*
+
+Lazyness is when an expression is only evaluated **when is necessary**.
+
+## Features
+
+- Interpreted
+- Dynamic typed
+- Functional (impure)
+- Curried
+- Lazy evaluation
+- It's a Lisp
+
+## Inspiration
+
+This language is being created for fun.
+
+It takes inspiration of some features of *Haskell* (like currification and lazy evaluation) and the syntax of *Lisp*.
+
+## A small taste
+
+``` lisp
+cherry> (set! x 10)
+nil
+cherry> x
+10
+cherry> (const 3 6)
+3
+cherry> (set! always-seven (const 7))
+nil
+cherry> always-seven
+#[lambda y x]
+cherry> (always-seven 1)
+7
+cherry> (always-seven 8)
+7
+```
+
+## Download and build instructions
+
+Install the *stack* build tool. On *Debian* based systems, run (as root):
+
 ```
 # apt install haskell-stack
+```
+
+Clone the repo:
+
+```
 $ git clone https://git.fai.su/Suguivy/cherry-lisp
+
+```
+
+Compile it:
+
+```
 $ cd cherry-lisp
-# stack upgrade
+$ stack upgrade
 $ stack build
+```
+
+Install and execute it:
+
+```
 $ stack install
 $ cherry
 ```
