Markdown

Markdown is a lightweight way to format text using plain symbols. Every note in trip2g is a .md file. It opens in Obsidian, VS Code, Notepad, or any text editor. No app owns the format.

Summary

Markdown uses # for headings, ** for bold, * for italic, - for lists, and triple backticks for code blocks. Wikilinks ([[Note Name]]) are an Obsidian extension for connecting notes. Frontmatter — a YAML block between --- markers at the top of a file — controls how trip2g publishes the note: its URL, visibility, and position in navigation.

Headings

# Heading 1
## Heading 2
### Heading 3

Use one # for the page title. Subsections get ## and ###. Going deeper than three levels is usually a sign the content should be split into separate notes.

Text formatting

**bold**
*italic*
~~strikethrough~~
`inline code`

Links

Standard Markdown link:

[link text](https://example.com)

Wikilinks

Wikilinks are an extension to standard Markdown, introduced by Obsidian and supported natively by trip2g. They're not part of the Markdown spec — they're a convention for linking notes inside a vault.

[[Note Name]]
[[Note Name|Display Text]]

The text inside [[ and ]] is the filename of the target note (without .md). No path needed — trip2g finds the file anywhere in the vault.

Backlinks. When note A links to note B, note B automatically knows about it. Open any note and see every note that references it. Connections you didn't plan become visible.

Embed. Prefix with ! to embed a note or image inline:

![[image.png]]
![[Another Note]]

Standard Markdown doesn't have backlinks or vault-aware resolution. That's the gap wikilinks fill.

Lists

Unordered:

- First item
- Second item
  - Nested item

Ordered:

1. First step
2. Second step
3. Third step

Task list:

- [ ] To do
- [x] Done

Images

Standard Markdown:

![alt text](path/to/image.png)

Obsidian-style embed (recommended in Obsidian vaults):

![[image.png]]

Both work in trip2g. The Obsidian embed resolves the file from anywhere in your vault without a path.

Code

Inline code uses single backticks:

Run `npm install` to install dependencies.

Fenced code block with optional language hint for syntax highlighting:

```javascript
function greet(name) {
  return `Hello, ${name}`;
}
```

Blockquotes

> This is a blockquote.
> It can span multiple lines.

Tables

| Column A | Column B | Column C |
| -------- | :------: | -------: |
| left     | center   | right    |
| aligned  | aligned  | aligned  |

Colons in the separator row control alignment: left (default), center (:---:), right (---:).

Frontmatter

Frontmatter is a YAML block at the very top of a Markdown file, enclosed by --- markers:

---
title: "My Note"
slug: my-note
free: true
---

Everything between the two --- lines is metadata. It does not appear as visible content on the page. trip2g reads this block to know how to publish the note.

Common frontmatter fields trip2g recognizes:

Field	Purpose
`title`	Page title shown in browser tab and site navigation
`slug`	URL path override — e.g. `slug: /docs/intro`
`free: true`	Makes the note publicly visible without a subscription
`home_position`	Controls sort order in magazine-style index pages
`lang_redirect`	Links to the equivalent page in another language

If free is absent, the note is subscriber-only by default. If slug is absent, trip2g derives the URL from the file path.
