++ This browser was built with ungoogled-chromium patches and differs from the default Chromium experience
++ in a few ways. Look over the sections below and the
++ <a href="https://github.com/ungoogled-software/ungoogled-chromium/blob/master/docs/default_settings.md">
++  changes to the default settings</a> to see what may be important to you.<p>
++ This page can always be accessed again at <a href="chrome://ungoogled-first-run">chrome://ungoogled-first-run</a>

++ <h2>How-To</h2>
++ <details><summary><b>Install and update extensions</b></summary><br>
++  <a href="https://github.com/NeverDecaf">NeverDecaf</a> has created an extension to make this process easy:
++  <ol>
++   <li>Set <a href="chrome://flags/#extension-mime-request-handling">chrome://flags/#extension-mime-request-handling</a>
++    to <code>Always prompt for install</code> and relaunch.</li>
++   <li>Then click on the latest <code>Chromium.Web.Store.crx</code> link on
++    <a href="https://github.com/NeverDecaf/chromium-web-store/releases">the extension's Releases page</a>.</li>
++  </ol>
++  Please check out the <a href="https://github.com/NeverDecaf/chromium-web-store">chromium-web-store</a>
++  repo for further details and alternate installation methods for the extension.<br><br>
++  If you do not wish to install this extension, there is still a way to install other extensions albeit
++  without the ability to easily update them. In this case, please refer to the entry on the wiki for
++  <a href="https://ungoogled-software.github.io/ungoogled-chromium-wiki/faq#downloading-the-crx-file">
++   installing extensions manually</a>.</details>
++ <details><summary><b>Keep login and session data</b></summary><br>
++  By default ungoogled-chromium has <code>Clear cookies and site data when you close all windows</code> enabled.<br>
++  This option can be changed in
++  <a href="chrome://settings/cookies?search=Clear+cookies+and+site+data+when+you+close+all+windows">
++   chrome://settings/cookies</a>.</details>
++ <details><summary><b>Enable spellcheck</b></summary>
++  <ol>
++   <li>Go to <a href="https://chromium.googlesource.com/chromium/deps/hunspell_dictionaries/+/main">
++     https://chromium.googlesource.com/chromium/deps/hunspell_dictionaries/+/main</a></li>
++   <li>Find a bdic file for the language you want and click on it.
++    You will see a mostly empty page aside from "X-byte binary file".</li>
++   <li>On the bottom right corner, click "txt". The direct link for en-US-10-1.bdic is:
++    <a href="https://chromium.googlesource.com/chromium/deps/hunspell_dictionaries/+/main/en-US-10-1.bdic?format=TEXT">
++     https://chromium.googlesource.com/chromium/deps/hunspell_dictionaries/+/main/en-US-10-1.bdic?format=TEXT</a></li>
++   <li>This is a base64-encoded file that needs to be decoded. Use the button below to select the .txt file you saved
++    and save/move the resulting bdic file to your Dictionaries directory. Default locations:
++    <ul>
++     <li>Linux: <code>~/.config/chromium/Dictionaries/</code><br></li>
++     <li>Mac: <code>~/Library/Application Support/Chromium/Dictionaries/</code><br></li>
++     <li>Windows: <code>%LOCALAPPDATA%\Chromium\User Data\Dictionaries\</code><br></li>
++    </ul>
++    <input id="bdic" type="file" accept=".txt,text/plain" />
++   </li>
++   <li>Toggle spell check in <a href="chrome://settings/languages">chrome://settings/languages</a>,
++    or restart the browser for the dictionaries to take effect.</li>
++  </ol></details><p>
