+## Hello There 👋
+
+### Values
+
+There are 3 types of values, and they can model the **WORLD** !\
+_(In the end it's all `1`'s and `0`'s for the computer)_, but us, **humans**, need
+an easier way of representing stuff.
+
+> We can all agree that `11010001100101110110011011001101111` is not a very
+> friendly way to say `'hello'` !
+
+#### Numbers 🔢
+
+- Whole numbers: `1`, `23`, `232139283`
+- Negative numbers are prefixed with `-`: `-1`, `-1231`
+- Decimal numbers: `3.14`, `-2.53343` etc...
+
+Use them for _quantities_ like in daily life.
+
+#### Booleans ✖️ / ✔️
+
+We use them when something is either `true` or `false`.
+
+They can be used to represent an answer to a closed-ended question _(anything that can
+be answered with yes or no)_.
+
+> We would answer the question *Is your screen turned on ?*
+> with the value `true` _(most likely)_.
+
+#### Strings 🆒
+
+- `'Hello'`
+- `'This is some text'`
+
+A string is a sequence of characters used to represent text, it needs
+**delimiters** to define its _begining_ and _end_.\
+Delimiters are matching quotes, either `` ` ``, `"` or `'`.
+
+### Using `console.log`
+
+To display output from a script into a console, use the function `console.log`:
+
+```js
+console.log() // <- will show an empty line
+```
+
+Add any value between the parentheses to see it appear when the script is
+executed.
+
+> It is very important to use this often to validate that our code is valid. The
+> more it is tested, the easier it is to understand what's going on in the code
+> !
+>
+> In doubt, `console.log` everything, don't be shy, they are for free.
+
+### Instructions
+
+In the editor block, write a program that displays:
+
+- the exact text `Hello There !`
+- any `Number`
+- and a `Boolean`.
+
+### Recommendation
+
+Videos designed to give **hints** are assigned to each quest. It is strongly suggested to watch them as you go.
+
+### You will learn about
+
+- JavaScript primitive values
