Lumocs provides flexibility in customizing various parts of your documentation. Whether it's adding extra content between the <head> tags, changing the color, customizing the footer, or altering the sidebar, Lumocs offers a straightforward approach to achieve this.

Changing the color

Lumocs supports changing the color (hue) of the entire site by changing a single css variable. Add the code below to your _includes/head.njk to change the color:

Move the slider to update the code and get a live demo:

:root {
   --primary-h: 25; /* Any value from 0 to 255 controlling the Hue */

Inserting Extra Content Between <head> Tags

To insert additional content, such as custom meta tags, stylesheets, or scripts, between the <head> tags, modify the _includes/head.njk file.

Adding a favicon

To add favicon functionality and optionally include a manifest, follow these steps:

  1. Place all your favicon images (e.g., favicon.png, favicon.ico, etc.) in the "img" folder within your "src" directory.

  2. Open the _includes/head.njk file.

  3. Add the following code to the file:

    <link rel="icon" type="image/png" href="/img/favicon.png" sizes="32x32">
    <link rel="icon" type="image/png" href="/img/favicon.png" sizes="192x192">
    <!-- Add more favicon sizes as needed -->
    <link rel="manifest" href="/img/manifest.json">

    Make sure to replace 'img/favicon.png' with the correct path to your favicon image, and add more <link> elements for different favicon sizes if necessary.

  4. Optionally, if you have a manifest.json file for the web app manifest, include it in the root folder, and add the appropriate <link> tag in _includes/head.njk:

    <link rel="manifest" href="manifest.json">
  5. Make sure to copy the img folder and optionally manifest.json to the output by including these lines in _config.ts:


To tailor the footer of your documentation, edit the _includes/footer.njk file. This could be useful for adding copyright notices, links to privacy policies, or any other pertinent information.

Adjusting the Sidebar

To add extra content to the sidebar, add the _includes/sidebar.njk file.

If you'd like to move the sidebar to the right side of the page, override the layout key of the front matter or _data.json to page_right.njk.

Advanced Customization: Overriding Templates

For those who require more advanced customization capabilities, Lumocs allows you to override templates entirely:

  1. Visit the Lumocs repository on GitHub:

  2. Download the template file you wish to modify.

  3. Modify the file as per your requirements.

  4. Place the modified copy in your project's _includes directory.

By supplying a modified copy of any of these files in the _includes directory, Lumocs will prioritize your custom version over the default one.
