Insert Code

Inline Code

A single backtick on each side, for naming a variable, a file or a command mid-sentence:

Check `package.json` before running `npm run build`.

Shortcut: ⌘`. Inline code renders in a monospace face on a faint tinted background.

Code Blocks

Three backticks on their own lines. Put the language name after the opening fence:

```swift
func greet(_ name: String) -> String {
    "Hello, \(name)"
}
```

Shortcut: ⌘⇧C. The language may be omitted; supplying it colours the block accordingly. Everything inside a fence is preserved literally — asterisks, hashes and pipes are never read as Markdown.

Mermaid Diagrams

Name the language mermaid and the fence stops being code and becomes a diagram:

```mermaid
flowchart LR
    A[Idea] --> B[Note]
    B --> C[Node]
    C --> D[Graph]
```

Flowcharts, sequence diagrams, state diagrams and Gantt charts all work. As with tables and math, it renders as a diagram while the cursor is elsewhere and reverts to source when the cursor enters — edit a line and watch the picture follow.

When the diagram will not draw

Mermaid is strict: one malformed arrow and nothing renders. Move the cursor into the fence to see the source — it is usually an arrow direction or a node bracket, and the opening declaration such as flowchart LR is required.
