Callouts for notes, warnings, and tips. There are six types available: note (default), important, tip, info, warning, comingSoon.

<Admonition type="warning" title="Important">
Critical information requiring immediate attention.
</Admonition>

Live preview:

Warning: Important

Critical information requiring immediate attention.

All Admonition types:

Note: Note

Highlights information that users should take into account.

Important: Crucial information necessary for users to succeed.

Tip: Pro tip

Optional information to help a user be more successful.

Info: Information that helps users understand things better.

Warning: Critical content demanding immediate user attention due to potential risks.

Coming soon: Information about features that are coming soon.

Highlighted block for supplementary information the reader should notice, but that doesn't carry the urgency of an Admonition. Use it for tips, best practices, or "good to know" context. The default label is "Good to know".

<Callout title="Before you start">

Make sure you have Node.js 18+ installed.

</Callout>

Before you start:

Make sure you have Node.js 18+ installed.

Props:

When to use Callout vs Admonition:

• Callout — supplementary context, best practices, or neutral "good to know" information.
• Admonition — warnings, important notices, tips with urgency, or coming-soon flags. Use when missing the information could cause user error.

Numbered step-by-step instructions split by h2 headings.

Components for organizing content into tabs.

Multi-language code examples with tabs.

<CodeTabs labels={["JavaScript", "Python", "Go"]}>

```javascript
const { Client } = require('pg');
const client = new Client({
  connectionString: process.env.DATABASE_URL,
});
await client.connect();
```

```python
import psycopg2
import os

conn = psycopg2.connect(os.environ["DATABASE_URL"])
cur = conn.cursor()
```

```go
import (
    "database/sql"
    _ "github.com/lib/pq"
)

db, err := sql.Open("postgres", os.Getenv("DATABASE_URL"))
```

</CodeTabs>

Live preview:

JavaScript

const { Client } = require('pg');
const client = new Client({
  connectionString: process.env.DATABASE_URL,
});
await client.connect();

Python

import psycopg2
import os

conn = psycopg2.connect(os.environ["DATABASE_URL"])
cur = conn.cursor()

Go

import (
    "database/sql"
    _ "github.com/lib/pq"
)

db, err := sql.Open("postgres", os.Getenv("DATABASE_URL"))

General tabbed content (not just code). For code-specific tabs, use CodeTabs instead.

<Tabs labels={["Console", "CLI", "API"]}>
<TabItem>
Create a database using the Neon Console by navigating to your project dashboard and clicking "Create Database".

Components for structuring and organizing page content.

Technology cards with icons, titles, and descriptions. These components use different icon systems - see the comparison table below to choose the right one.

Standard technology cards layout using TechCards icons:

<TechCards>
  <a
    href="/docs/guides/node"
    title="Node.js"
    description="Connect Node.js applications to Neon"
    icon="node-js"
  >
    Node.js
  </a>
  <a
    href="/docs/guides/python"
    title="Python"
    description="Connect Python applications to Neon"
    icon="python"
  >
    Python
  </a>
  <a
    href="/docs/guides/nextjs"
    title="Next.js"
    description="Build Next.js apps with Neon"
    icon="next-js"
  >
    Next.js
  </a>
</TechCards>

Live preview:

  </a>
  <a
    href="/docs/cloud/aws"
    title="AWS integration"
    description="Deploy and scale with AWS"
    icon="aws"

InfoBlock creates a multi-column layout for organizing related content sections. Use it for "at-a-glance" summaries at the top of documentation pages, combining learning objectives with related resources. Use two columns.

Key Features:

• Commonly paired with DocsList for structured content presentation
• Ideal for page introductions and overview sections

Basic Two-Column Layout:

<InfoBlock>
<DocsList title="What you will learn:">
<p>How to view and modify data in the console</p>
<p>Create an isolated database copy per developer</p>
<p>Reset your branch to production when ready to start new work</p>
</DocsList>

<DocsList title="Related topics" theme="docs">

Two-column layout for tutorials and reference documentation. Use TwoColumnLayout.Step for numbered tutorial steps, TwoColumnLayout.Item for reference items.

Add layout: wide to the page frontmatter when using this component, to hide the right sidebar and give the layout more room.

<TwoColumnLayout>

<TwoColumnLayout.Step title="Install dependencies">
<TwoColumnLayout.Block>

Install the required packages.

</TwoColumnLayout.Block>
<TwoColumnLayout.Block label="Terminal">

```bash

Individual checklist items used within CheckList components.

<CheckItem title="Task name" href="#anchor">
  Description of the task or requirement
</CheckItem>

Usage Notes:

• Always used within a <CheckList> component
• title prop is required
• href prop is optional for anchor linking
• Content is the description text

The standard, SEO-friendly frequently-asked-questions section for the end of docs and guides. Use it instead of ad-hoc ### question headings, **Q:/A:** text, or DefinitionList for FAQs, so every FAQ looks and behaves the same. It emits FAQPage schema.org JSON-LD to help search engines and AI agents parse the questions and answers, and it renders each answer with native collapsible <details>, so answers stay crawlable and accessible even when collapsed. It also gives every FAQ consistent styling and deep-link anchors.

Add a ## Frequently asked questions heading above the component (sentence case) so the section appears in the table of contents.

## Frequently asked questions

<Faq>

<FaqItem question="What is a branch?">
A branch is a copy-on-write clone of your data that you can create from a current or past state.
</FaqItem>

<FaqItem question="Does creating a branch affect my production database?">
No. Creating a branch does not increase load on the parent branch or affect its performance.
</FaqItem>

</Faq>

Live preview:

A branch is a copy-on-write clone of your data that you can create from a current or past state.

No. Creating a branch does not increase load on the parent branch or affect its performance.

Usage Notes:

• FaqItem requires a question prop. It renders as an <h3> inside the summary and is used verbatim in the JSON-LD.
• id (optional) sets the anchor; it defaults to a slug of the question, so #your-question deep links work.
• defaultOpen (optional) renders an item expanded on load.
• Answers accept full markdown (lists, tables, links, images, code). Keep blank lines around block content.
• Questions do not appear in the table of contents; the ## Frequently asked questions heading is the single TOC entry.
• Put shared blocks like <NeedHelp/> after </Faq>, not inside an item.

Prominent call-to-action buttons for important actions.

<CTA
