description: Use this resource for guidance on using our custom Next.js components and syntax
---
Teleport uses Next.js to generate its static documentation site. Next.js uses Markdown with React, hence the `.mdx` filename suffix.
This section briefly describes some of the features that are most relevant when writing documentation.
## Code blocks
You will often need to illustrate documentation with examples of commands, code,
or configuration files. You can do this by adding a code block. Code blocks
begin and end with three backticks. A label after the first row of backticks
configures the way the block will be rendered:
````md
```yaml
key: value
array:
- val1
- val2
- val3
```
````
If a code block's label is `code` or `bash`, the block will be optimized for
example commands. Readers will be able to copy individual lines that begin with
`$`. Comments and output will be highlighted differently than commands.
Here is an example of a `code` block:
````md
```code
# Comment
$ tsh login
Output
```
````
Here is the same block after rendering:
```code
# Comment
$ tsh login
Output
```
## Variables, templating, and interpolation
Many documentation teams struggle with maintaining the vast number of articles
and resources that are eventually created and consumed. Links and images have to
be rechecked for accuracy and relevance.
To ease this burden, we can replace links and code examples with *variables* so we don't have to constantly update everything after each release.
Variables are stored in the `docs/config.json` file under the key `variables`.
To insert a variable into a page, use the `(\= path.to.variable \=)` syntax (remove backslashes in the actual Markdown).
Variables will be linted when a PR is created as part of our CI/CD process. If a variable does not exist in the config, you will see an error that you must remedy in order to merge your PR.
## Partials
To prevent content duplication, it's useful to include code examples or Markdown
content from a partial file into the current page. This allows our documentation
to reduce maintenance overhead so we can focus on writing new articles.
To include a partial, use the following syntax: `(\!path-to-file.mdx\!)` syntax (remove the backslashes in an actual page).
Paths are resolved from the root of the repository.
Partials will be linted when a PR is created as part of our CI/CD process. If a
partial does not exist in the repository, our system will throw an error.
Incorrect placement of include statements will also throw errors.
Partials will only be included in these two cases:
### Surrounded by newlines
```md
Some text.
(\! include.mdx \!)
Some other text.
```
If the partial is an `.mdx` file, it will be parsed and rendered as Markdown. In other cases
it will be included as-is.
### Inside code blocks
````md
```code
# Code example below
(\!include.sh\!)
```
````
These will be inserted as-is, even in the case of `.mdx` files.
## Image pixel density markers
Browsers can't distinguish between images that are suitable for Apple's Retina display and images that are not. Because of this, screenshots taken on Retina screens may look large on the page.
To hint to browsers that an image is meant for a Retina display, we can add the
suffix `@Nx` to the image's file name. For example, screenshots made on MacOS
should have the suffix `filename@2x.png`. This will tell the browser to scale
images down twice to show them in their actual size.
## Scopes
There are three versions of Teleport: `oss`, `enterprise`, and `cloud`. Readers can switch the scope of the documentation using a dropdown menu at the top of the page.
Based on the selector's value, some `.mdx` components can hide or show different content sections. Check the components' descriptions below to see which component can be affected by this selector. These components will include the `scope` property.
If `scope` is set, the component will be only shown if the scope is selected via
the dropdown menu. `scope` can be either a single string or an array of strings.
Possible values are `oss`, `enterprise`, and `cloud`. For an array of strings,
use this syntax: `scope={["oss", "cloud"]}`.
## Notices
Notice content.
If you want to add notice like the one above to the page, use this syntax:
```
Notice content.
```
`type` can be one of the following values: `warning`, `tip`, `note`, `danger`. The default is `tip`.
Different types will result in different background colors and icons.
`scope` is an optional property that specifies the component's [scope](./reference.mdx#scopes).
## Admonitions
Admonition content.
Admonitions are similar to notices, but are intended for longer content that looks better against a white background. Use this syntax:
```jsx
Admonition content.
```
`type` can be one of the following values: `warning`, `tip`, `note`, `danger`.
Different types will result in different colors for the header. Omitting the type
or using some other value will result in resetting it to the `tip`.
If `title` is omitted, `type` will be used instead as the title value.
`scope` is an optional property that specifies the component's
[scope](./reference.mdx#scopes). If the `scopeOnly` property is provided and the
user-selected scope is not included in `scope`, the `Admonition` will be hidden.
## Tabs
First tab.
Second tab.
To insert a tabs block like the one above, use this syntax:
```jsx
First tab.
Second tab.
```
`scope` is an optional property that specifies the component's [scope](./reference.mdx#scopes). Selecting a scope via the dropdown menu at the top of the page switches the `Tabs` component to the tab associated with that scope.
## Details
Details content
To insert a details block like the one above, use this syntax:
```
Details content
```
`scope` is an optional property that specifies the component's [scope](./reference.mdx#scopes).
If `scopeOnly` is assigned to `{true}`, the component will only be visible
in the provided scope and invisible in all other scopes.
## Figures
{/* TODO: Document all props */}
The `Figure` component can help with using images, figures, and diagrams:
```jsx
```
## ScopedBlock
Use the `ScopedBlock` component if you want to render some Markdown only for
users of open source Teleport, Teleport Cloud, or Teleport Enterprise.
`ScopedBlock` has a single property, `scope`, that works the same as it does for
other components we use in the documentation. See our
[explanation](./reference.mdx#scopes) of how to use the `scope` property.
Use this instead of the `Tabs` component when:
- You want to conceal details that aren't relevant to the reader's scope.
- The components you use don't look presentable within a `TabItem`, e.g., you're
including a separate `Tabs` component for each scope.
Any Markdown and MDX components can be included within a `ScopedBlock`.
```jsx
Here are some options for installing the Teleport Auth and Proxy Services on
your own infrastructure.
{/* TabItems that vary between scopes */}
```
## Videos
To embed a video in a docs page, use the `video` tag:
```html
```
