Create a personal knowledge base and share your knowledge with your peers.

Hugo Blox web framework empowers you with one of the most flexible note-taking capabilities out there.

Create a powerful knowledge base that works on top of a local folder of plain text Markdown files.

Use it as your second brain, either publicly sharing your knowledge with your peers via your website, or via a private GitHub repository and password-protected site just for yourself.

Mindmaps

Hugo Blox supports a Markdown extension for mindmaps.

With this open format, can even edit your mindmaps in other popular tools such as Obsidian.

Simply insert a Markdown code block labelled as markmap and optionally set the height of the mindmap as shown in the example below.

Mindmaps can be created by simply writing the items as a Markdown list within the markmap code block, indenting each item to create as many sub-levels as you need:


```markmap {height="200px"}
- Hugo Modules
  - Hugo Blox
  - blox-plugins-netlify
  - blox-plugins-netlify-cms
  - blox-plugins-reveal
```

renders as

- Hugo Modules
  - Hugo Blox
  - blox-plugins-netlify
  - blox-plugins-netlify-cms
  - blox-plugins-reveal

Anh here’s a more advanced mindmap with formatting, code blocks, and math:

Callouts

Use callouts (aka asides, hints, or alerts) to draw attention to notes, tips, and warnings.

Use the > [!NOTE] syntax to create a callout.

> [!NOTE]
> A Markdown aside is useful for displaying notices, hints, or definitions to your readers.
