<p>Most GNU/Linux operating systems come with GnuPG installed on them, so if you're running one of these systems, you don't have to download it. If you're running macOS or Windows, steps to download GnuPG are below. Before configuring your encryption setup with this guide, though, you'll need a desktop email program installed on your computer. Many GNU/Linux distributions have one installed already, such as Icedove, which may be under the alternate name "Thunderbird." Programs like these are another way to access the same email accounts you can access in a browser (like Gmail), but provide extra features.</p>

<h3><em>Step 2.b</em> Some important steps following creation</h3>
-<h6>Upload your key to a keyserver</h6>
+<h4>Upload your key to a keyserver</h4>
<p>We will upload your key to a keyserver, so if someone wants to send you an encrypted message, they can download your public key from the Internet. There are multiple keyservers
that you can select from the menu when you upload, but they are all copies
of each other, so it doesn't matter which one you use. However, it sometimes
takes a few hours for them to match each other when a new key is uploaded.</p>
-<p># Copy your keyID <span style="color:#2f5faa; font-family: monospace;">gnupg --list-key [your@email]</span> will list your public ("pub") key information, including your keyID, which is a unique list of numbers and letters. Copy this keyID, so you can use it in the following command.</p>

+<h4>Export your key to a file</h4>
<p>Use the following command to export your secret key so you can import it into your email client at the next <a href="#section3">step</a>. To avoid getting your key compromised, store this in a safe place, and make sure that if it is transferred, it is done so in a trusted way. Exporting your keys can be done with the following commands:</p>
+<p><code>
+$ gpg --export-secret-keys -a [keyID] > my_secret_key.asc<br/>

-<h6>Generate a revocation certificate</h6>
