Bold

Bold is used for navigational elements within a given interface:

Go to Account > Security > Personal Access Tokens.

Go to **Account** > **Security** > **Personal Access Tokens**.

Callouts

There are several types of callouts commonly used in our docs:

Notes

Notes should identify important pieces of information the reader shouldn't miss.

<Alert title="Note"  type="info" >

Notes should identify important pieces of information the reader shouldn't miss.

</Alert>

Warnings

Warnings cover information critical to the reader and highlight potential dangers, especially those that can cause data loss.

<Alert title="Warning" type="danger" >

Warnings cover information critical to the reader and highlight potential dangers, especially those that can cause data loss.

</Alert>

Success

Success callouts are used infrequently, usually in guides with specific end results expected. Use success callouts to differentiate between two binary results.

<Alert title="Incorrect DNS Configuration" type="danger" icon="remove">

![Incorrect vanity domain A record required DNS value](../images/dashboard/wrong-vanity-aname-dns.png)

</Alert>

<Alert title="Correct DNS Configuration" type="success" icon="check">

![Correct vanity domain A record required DNS value](../images/dashboard/correct-a-aaaa-dns.png)

</Alert>

Cards

Use cards to visually display a list of items, with links to more information.

CardGroup/Card is intended for Terminus guide use only. Instead, use ProductGroup/Product

Before You Begin Sections

This section should outline any steps or services required before starting those in the doc. If there are other docs that should be completed first, list them here.

Of particular note, any documentation that uses Terminus should reference it in this section, and link to the Terminus Guide .

Before You Begin

Be sure that you have:

An existing WordPress site on Pantheon, or create one.
A local clone of your code repository.
An account with Amazon Web Services (AWS). Amazon offers free access to most of their services for the first year.
Terminus installed on your local computer.

## Before You Begin

Be sure that you have:

- An existing WordPress site on Pantheon, or [create](https://dashboard.pantheon.io/sites/create) one.
- A [local clone](/guides/git/git-config#clone-your-site-codebase) of your code repository.
- An account with [Amazon Web Services (AWS)](https://aws.amazon.com/s3/). Amazon offers [free access](https://aws.amazon.com/free/) to most of their services for the first year.
- [Terminus](/terminus) installed on your local computer.

Export Local Environment Variables

Be kind. If you're writing a guide that will use one or more example variables the reader must replace when following along, you should walk them through exporting them to local environment variables. See the Variables section below for more details.

Code Samples

Inline

Used for file names, variables, commands, and output, inline within paragraphs:

Inline code styling using backticks, like $EXAMPLE.

Inline code styling using backticks, like `$EXAMPLE`.

Blocks

/**
* Example Comment
*
* To provide additional context for the following
* code, and defining any variables the user must
* manually edit.
**/
if (!function_exists('install_drupal')) {
  $conf['preprocess_css'] = 1;
}

```php
# This is a Windows-friendly symlink
require_once WP_CONTENT_DIR . '/plugins/wp-redis/object-cache.php';
```

Shell Prompts

You can also define a single line code block as a command:

mkdir -p ~/repos/mdx-slug

```bash{promptUser: user}
mkdir -p ~/repos/mdx-slug
```

Or define which lines are output:

ls  -1 ~/repos
documentation
i3lock-color
i3lock-fancy
j4-dmenu-desktop
mdx-slug

```bash{outputLines:2-6}
ls  -1 ~/repos
documentation
i3lock-color
i3lock-fancy
j4-dmenu-desktop
mdx-slug
```

Line Highlighting

You can highlight a specific line in a code block the reader should focus on with //highlight-line, or a group with //highlight-start and //highlight-end:

Content Types

The site features two distinct content types; docs and guides. We define docs as reference materials used to explain the behavior and intended use of Pantheon's platform features and service offerings. Guides are paginated and designed to walk the reader through a complex feature/product or to provide a collected resource of related topics in one location.

DNS

Creates a bulleted list of links to all DNS Provider docs stored in source/content/dns-providers, which do not have draft: true frontmatter.

<DNSProviderDocs />

File Downloads

Creates a link to a downloadable file. Files must be stored in source/scripts.

<Download file="pantheon-backup-to-s3.sh" />

Definitions

A dfn tag is used to indicate that a paragraph is defining a new term. New terms should only be defined once throughout the docs, and then cross-referenced. Definitions and Definition Lists are automatically added to the Glossary.

A <dfn id="dfn">dfn</dfn> tag is used to indicate that a paragraph is defining a new term.
New terms should only be defined once throughout the doc, and then cross-referenced.
Definitions and Definition Lists are automatically added to the [Glossary](/glossary).

Error Messages

When referencing error messages in the body of an article, format them as monospace, and either place them inline (if short) or as a new paragraph (if long).

When providing solutions to error messages, document them verbatim as H3s within a Troubleshooting section. Use the exact copy of the error message to help improve search result findability. Making the header an H3 makes the section linkable within the table of contents for easy sharing.

RedisException: Redis server went away

The following error occurs when Redis has not been enabled within the Site Dashboard:

RedisException: Redis server went away in Redis->setOption() (line 28 of /srv/bindings/xxxxxxxx/code/sites/all/modules/redis/lib/Redis/Client/PhpRedis.php).

Enable Redis via the Pantheon Site Dashboard by going to Settings > Add Ons > Add > Redis. It may take a few minutes to provision the service.

### RedisException: Redis server went away
The following error occurs when Redis has not been enabled within the Site Dashboard:

 ```none
 RedisException: Redis server went away in Redis->setOption() (line 28 of /srv/bindings/xxxxxxxx/code/sites/all/modules/redis/lib/Redis/Client/PhpRedis.php).
 ```

Enable Redis via the Pantheon Site Dashboard by going to **Settings** > **Add Ons** > **Add** > **Redis**. It may take a few minutes to provision the service.

Redirects

Redirects are required whenever you change an existing URL or when a doc or guide is deprecated and removed from the Docs site. Deprecated pages should always be redirected to related content so users to do not receive a 404. Always add the Redirect label to the PR that includes a redirect. This allows us to find these changes later if we need to reference why a page was moved or deleted.

When you're moving a doc or heading to a new location, include a formatted table with your redirect request in the Pull Request comments.

Redirect from	to
docs.pantheon.io/drush	sc=301\|t=https://docs.pantheon.io/guides/drush

Reusable Content/Partials

Create reusable content in a separate Markdown file that can be included within sections of other docs. These are called partials.

Place the Markdown file within the source/partials/ directory, in its own directory if it is feature-specific.

Partial file names must not duplicate the names of files in the source/content directory.

Partials use all of the same Markdown, style, and HTML as needed and outlined on this page, but do not require frontmatter. They can be included as their own paragraphs and sections as well as in lists as a step or bullet point.

After you create the file, include it in the doc:

<Partial file="partial-example.md" />

To find partials to reuse, run this report (requires a local build of gatsby). The report can be filtered by metadata tags, and includes an excerpt of each partial.

Review Dates

Review dates indicate the last time a member of the Documentation team reviewed a document. There are two ways to indicate review dates.

The most common is by using the frontmatter reviewed: "YYYY-MM-DD" . The other is at the section level, using the ReviewDate component:

### Section Title
<ReviewDate date="YYYY-MM-DD" />

Screenshots

Submit screenshots without additional markup. For example, don't use Skitch to add an arrow. This helps the Docs team make edits as needed later.

Do not include any personal information like a name, email address, or UUID in the screenshot.

GUI

Screenshots are used to reference GUI instructions:

![Alt text describing the image](../images/dashboard/terminus-cli-code-to-commit-dashboard.png)

Terminal

Terminal screenshots should be described in the text as much as possible, and should only be used to demonstrate intended output:

![Alt text describing the image](../images/pr-workflow/composer-require-pathauto.png)

Tables

You can use markdown tables to describe availability based on service levels before providing instructions on how to enable or use a given feature. For example:

Enable Redis

All plans except for a Basic plan can use Redis. Redis is available to Sandbox site plans for developmental purposes, but Redis will not be available going live on a Basic plan.

Plans	Redis Support
Sandbox	✔
Basic	❌
Performance	✔
Elite	✔

## Enable Redis

All plans except for a Basic plan can use Redis. Redis is available to Sandbox site plans for developmental purposes, but Redis will not be available going live on a Basic plan.

| Plans         | Redis Support <Popover content="Available across all environments, including Multidevs." /> |
| ------------- | -------------------------------------- |
| Sandbox       | <span style="color:green">✔</span> |
| Basic         | ❌  |
| Performance   | <span style="color:green">✔</span> |
| Elite         | <span style="color:green">✔</span> |

Use ✓ to indicate yes and ❌ to indicate no.

Visit the Markdown Tables Generator for help with creating nice-looking and well-formatted tables.

Advanced Tables

Standard markdown tables don't allow for cells to span multiple rows or columns, but by using the gatsby-remark-grid-tables plugin, we can overcome this limitation:

+-----------------+--------------+-------------+--------------+------------------------+

Tabs

When working on a document that will cover steps for multiple CMSs, use tabs when possible to condense instructions that need duplication for the different applications.

Note that active={true} is required for each first or default tab. Without it, the tabs will still load, but will appear broken until the reader clicks on a tab.

Here's our WordPress specific copy, and an example snippet:

/**
  * Some WordPress specific thing
  *
  */

Code goes here.

Here's our Drupal 7 specific copy, and an example snippet:

/**
  * Some Drupal 7 specific thing
  *
  */

Some code.

<TabList>

<Tab title="WordPress" id="wp-example" active={true}>

Here's our WordPress specific copy, and an example snippet:

```php
/**
  * Some WordPress specific thing
  *
  */

Some code.
```

</Tab>

<Tab title="Drupal 7" id="d7-example">

Here's our Drupal 7 specific copy, and an example snippet:

```php

Terminology

Personal Workspace: a user's personal work area, containing sites/settings specific to that user.
Professional Workspace: (formerly Organization) a feature set for a collection of users or sites.
Site Dashboard: the page the user gets when selecting a site from the Sites tab in a Workspace
Supporting Workspace: (formerly Supporting Organization): a Professional Workspace that's been added to a specific site's Team.

Tooltips

Tooltips are a great way to add additional information without cluttering up a section. For example, you can define jargon and even link out to an external resource without being distracting to the reader:

Given two new sites with slugs first-site and second-site, each configuration will result in the following URLs:

Subdirectories: example.com/first-site and example.com/second-site.
Subdomains: first-site.example.com and second-site.example.com.

Given two new sites with slugs <Popover title="Slugs" content="Generally, are URL friendly descriptions for a post or a page in WordPress. In the context of WordPress Multisite, a slug is a URL friendly description for a network site." /> `first-site` and `second-site`, each configuration will result in the following URLs:

* Subdirectories: `example.com/first-site` and `example.com/second-site`.
* Subdomains: `first-site.example.com` and `second-site.example.com`.

## Variables

When writing multi-step processes, repeated variables and constants should be defined before providing the first set of commands. If the doc has a "Before You Begin" section, define varables here. Provide them using the callout below, and follow common conventions (lowercase for variables, uppercase for constants).

This process uses Terminus extensively. Before we begin, set the variables $site and $env in your terminal session to match your site name and the Dev environment:

export site=yoursitename
export env=dev

<Alert title="Exports" type="export">

This process uses [Terminus](/terminus) extensively. Before we begin, set the variables `$site` and `$env` in your terminal session to match your site name and the Dev environment:

```bash{promptUser: user}
export site=yoursitename
export env=dev
```

</Alert>

Voice, Style, and Flow

Some General Rules:

Only assume as much knowledge from the reader as specified in the Before You Begin section. Otherwise explain everything.
Avoid be verbs.
Avoid personal opinions, feelings, or anecdotes. Use an informal but succinct tone.
Use Inclusive Language, avoid colloquialisms and hyperbole.
Use title case for section headings.

Where's the User?

It is important to direct the user to the area in which an activity is taking place. For example:

To create a backup:

Click the Backup tab.
More instructions...

This instruction does not tell the user where the Backup tab is - is it in a Workspace? If so, which one? Is it on a Site Dashboard?

Instead, start by placing the user in the correct location:
