 <h2>Creating your own repository<a class="headerlink" href="#Creating-your-own-repository" title="Link to this heading"></a></h2>
 <p>Now, you will create your own repository for practice. For this bootcamp, let’s name the repository with your initials followed by <code class="docutils literal notranslate"><span class="pre">_bootcamp</span></code>. In my case, my repository is <code class="docutils literal notranslate"><span class="pre">jb_bootcamp</span></code>.</p>
 <p>Only in rare circumstances would you not want to host your repository remotely, so we will take an easy path toward creating a repository using GitHub. Prior to the bootcamp, you all should have set up a GitHub account. Log in to GitHub. In the upper right corner of the page, click on the “<strong>``+``</strong>” icon and select “New repository.” You will then get a page that looks like this:</p>

 </center><p>I called the new repository <code class="docutils literal notranslate"><span class="pre">jb_bootcamp</span></code> (yours will obviously have your own initials, and you can substitute them for <code class="docutils literal notranslate"><span class="pre">jb</span></code> wherever you see that in this lesson), and gave a little description. You can choose the repository to be either private of public; if you are not an academic, you have to pay for private repositories. Public repositories can be viewed by anyone. I will choose public for this one.</p>
 <p>I have checked the box to initialized the repository with a README. This is convenient because GitHub will set up the repository and populate it with a README file that you can generate right in your browser. I also selected to add a Python <code class="docutils literal notranslate"><span class="pre">.gitignore</span></code>, which is convenient for keeping your version control clean (more on that <a class="reference external" href="#.gitignore">later</a>). Finally, I chose an MIT license, which is a liberal license that will let others use your code if they would like to.</p>
