A lot of examples with using of Telegram Bot API you can find in <a href="https://github.com/InsanusMokrassar/TelegramBotAPI-examples">this github repository</a></p>

<h3 id="the-most-simple-bot">The most simple bot<a class="headerlink" href="#the-most-simple-bot" title="Permanent link"></a></h3>
<p>The most simple bot will just print information about itself. All source code you can find <a href="https://github.com/InsanusMokrassar/TelegramBotAPI-examples/tree/master/GetMeBot">in this repository</a>. Our interest here will be concentrated on the next example part:</p>
<div class="language-kotlin highlight"><pre><span></span><code><span id="__span-0-1"><a href="#__codelineno-0-1" id="__codelineno-0-1" name="__codelineno-0-1"></a><span class="kd">suspend</span><span class="w"> </span><span class="kd">fun</span><span class="w"> </span><span class="nf">main</span><span class="p">(</span><span class="k">vararg</span><span class="w"> </span><span class="n">args</span><span class="p">:</span><span class="w"> </span><span class="kt">String</span><span class="p">)</span><span class="w"> </span><span class="p">{</span>

</span></code></pre></div>
<p>So, lets get understanding, about what is going on:</p>
<ol>
<li><code>suspend fun main(vararg args: String)</code>:<ul>
<li><code>suspend</code> required for making of requests inside of this function. For more info you can <a href="https://kotlinlang.org/docs/reference/coroutines/basics.html">open official documentation</a> for coroutins. In fact, <code>suspend fun main</code> is the same that <code>fun main() = runBlocking {}</code> from examples</li>
</ul>
</li>
<li><code>val botToken = args.first()</code>: here we are just getting the bot token from first arguments of command line</li>
<li><code>val bot = telegramBot(botToken)</code> : inside of <code>bot</code> will be <a href="https://tgbotapi.inmo.dev/docs/com.github.insanusmokrassar.-telegram-bot-a-p-i.bot/-requests-executor/index.html">RequestsExecutor</a> object which will be used for all requests in any project with this library</li>
<li><code>println(bot.getMe())</code>: here happens calling of <a href="https://tgbotapi.inmo.dev/docs/com.github.insanusmokrassar.-telegram-bot-a-p-i.extensions.api.bot/get-me.html">getMe</a> extension</li>
</ol>
<p>As a result, we will see in the command line something like</p>
<div class="language-shell highlight"><pre><span></span><code><span id="__span-1-1"><a href="#__codelineno-1-1" id="__codelineno-1-1" name="__codelineno-1-1"></a>ExtendedBot<span class="o">(</span><span class="nv">id</span><span class="o">=</span>ChatId<span class="o">(</span><span class="nv">chatId</span><span class="o">=</span><span class="m">123456789</span><span class="o">)</span>,<span class="w"> </span><span class="nv">username</span><span class="o">=</span>Username<span class="o">(</span><span class="nv">username</span><span class="o">=</span>@first_test_ee17e8_bot<span class="o">)</span>,<span class="w"> </span><span class="nv">firstName</span><span class="o">=</span>Your<span class="w"> </span>bot<span class="w"> </span>name,<span class="w"> </span><span class="nv">lastName</span><span class="o">=</span>,<span class="w"> </span><span class="nv">canJoinGroups</span><span class="o">=</span>false,<span class="w"> </span><span class="nv">canReadAllGroupMessages</span><span class="o">=</span>false,<span class="w"> </span><span class="nv">supportsInlineQueries</span><span class="o">=</span><span class="nb">false</span><span class="o">)</span>
