+# Demo Mini-Project
+
+## Number Guessing Game
+
+You are required to build a game that generates **a random integer from a random range**.
+
+The user will guess the number. You need to indicate whether the guess is **too small**, **too big**, or **correct**.
+
+Complete the JavaScript part of the ```index.html``` file.
+
+If you ever get stuck, feel free to check the ```hint.md``` for hints and the ```solution.js``` for the solution.

+# Hints
+
+## Step 1: Create a Random Number
+
+Use JavaScript to generate random numbers:
+
+```
+Math.random() // random number between 0 and 1
+```
+
+To create an interger in the range (min, min + range):
+
+```
+Math.floor(Math.random() * range) + min
+```
+
+## Step 2 (optional): Create a Random Range
+
+Instead of always generating a number from 1 to 100, try:
+
+* Generate a **random minimum**
+* Generate a **random maximum**
+
+Make sure that:
+
+```max > min``` and ```max - min >= range```
+
+# Get User Input
+
+Notice that there's already an ``` ``` box in HTML
+
+Useful syntax:
+
+```
+document.getElementById("html_id");
+```
+
+To get the value of HTML input:
+
+```variableName.value```
+
+**Tip:** The input from HTML returns a **string**, but you want a **number**
+
+## Step 4: Compare the Guess
+
+Use conditional statements:
+
+```
+if (condition 1)
+{
+ // too small
+}
+else if(condition 2)
+{
+ // too big
+}
+else
+{
+ // correct
+}
+```
+
