+# Simple Chatty Bot
+
+## About
+
+Here, at the beginning of your programmer’s path, creating a simple console chat bot will do wonders to guide you through the basics of coding. During this journey you will also play some word and number games that you are going to implement all on your own. Pack up and let’s hit the road, my friend!
+
+## Learning outcomes
+
+You’ll get to know the basic syntax of Python and write a simple program using variables, conditions, loops, and functions.

+<h2 style="text-align: center;">Description</h2>
+
+<p>Digital personal assistants help people to drive cars, plan their day, buy something online. In a sense, they are simplified versions of artificial intelligence with whom you can talk.</p>
+
+<p>In this project, you will develop step by step a simple bot that will help you study programming.</p>
+
+<h2 style="text-align: center;">Objective</h2>
+
+<p>For the first stage, you will write a bot who displays a greeting, its name, and the date of its creation. First impressions count!</p>
+
+<p>Your program should print the following lines:</p>
+
+<pre><code class="language-no-highlight">Hello! My name is {bot_name}.
+I was created in {birth_year}.</code></pre>
+
+<p>Instead of <code class="java">{bot_name}</code>, print any name you choose and replace <code class="java">{birth_year}</code> with the current year (four digits).</p>
+
+<h2 style="text-align: center;">Example</h2>
+
+<p>Output:</p>
+
+<pre><code class="language-no-highlight">Hello! My name is Aid.
+I was created in 2020.</code></pre>
+
+<p>You can change the text if you want but print exactly two lines.</p>
+
+<p>Next, we will use <strong>Aid</strong> and <strong>2020</strong> as your bot's name and its birth year, but you can change it if you need to.</p>

+<h2 style="text-align: center;">Description</h2>
+
+<p>Keep improving your bot by developing new skills for it. We suggest a simple guessing game that will predict the age of a user.</p>
+
+<p>It's based on a simple math trick. First, take a look at this formula:</p>
+
+<pre><code class="java">age = (remainder3 * 70 + remainder5 * 21 + remainder7 * 15) % 105</code></pre>
+
+<p>The numbers<code class="java">remainder3</code>, <code class="java">remainder5</code> and <code class="java">remainder7</code> are the remainders of division by 3, 5 and 7 respectively.</p>
+
+<p>It turns out that for each number ranging from <em>0</em> to <em>104</em> the calculation will result in the number itself. This perfectly fits the ordinary age range, doesn't it? Ask a user for the remainders and use them to guess the age!</p>
+
+<h2 style="text-align: center;">Objective</h2>
+
+<p>At this stage, you will introduce yourself to the bot. It will greet you by your name and then try to guess your age using arithmetic operations.</p>
+
+<p>Your program should print the following lines:</p>
+
+<pre><code class="language-no-highlight">Hello! My name is Aid.
+I was created in 2020.
+Please, remind me your name.
+What a great name you have, Max!
+Let me guess your age.
+Enter remainders of dividing your age by 3, 5 and 7.
+Your age is {your_age}; that's a good time to start programming!</code></pre>
+
+<p>Read three numbers from the standard input. Assume that all the numbers will be given on separate lines.</p>
+
+<p>Instead of <code class="java">{your_age}</code>, the bot will print the age determined according to the special formula discussed above.</p>
+
+<h2 style="text-align: center;">Example</h2>
+
+<p>The greater-than symbol followed by a space (<code class="java">&gt; </code>) represents the user input. Note that it's not part of the input.</p>
+
+<p><strong>Example 1:</strong> <em>a dialogue with the bot</em></p>
+
+<pre><code class="language-no-highlight">Hello! My name is Aid.
+I was created in 2020.
+Please, remind me your name.
+&gt; Max
+What a great name you have, Max!
+Let me guess your age.
+Enter remainders of dividing your age by 3, 5 and 7.
+&gt; 1
+&gt; 2
+&gt; 1
+Your age is 22; that's a good time to start programming!</code></pre>
+
+<p>Use the provided template to simplify your work. You can change the text, but not the number of printed lines.</p>
