+title: Introduction
+description: An overview of objects, tags, and filters in the Liquid template language.
+redirect_from: /basics/
+---
+
+Liquid uses a combination of [**objects**](#objects), [**tags**](#tags), and [**filters**](#filters) inside **template files** to display dynamic content.
+
+## Objects
+
+**Objects** contain the content that Liquid displays on a page. Objects and variables are displayed when enclosed in double curly braces: `{% raw %}{{{% endraw %}` and `{% raw %}}}{% endraw %}`.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{{ page.title }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{{ page.title }}
+```
+
+In this case, Liquid is rendering the content of the `title` property of the `page` object, which contains the text `{{ page.title }}`.
+
+## Tags
+
+**Tags** create the logic and control flow for templates. The curly brace percentage delimiters `{% raw %}{%{% endraw %}` and `{% raw %}%}{% endraw %}` and the text that they surround do not produce any visible output when the template is rendered. This lets you assign variables and create conditions or loops without showing any of the Liquid logic on the page.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% if user %}
+  Hello {{ user.name }}!
+{% endif %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+  Hello Adam!
+```
+
+Tags can be categorized into various types:
+
+- [Control flow]({{ "/tags/control-flow/" | prepend: site.baseurl }})
+- [Iteration]({{ "/tags/iteration/" | prepend: site.baseurl }})
+- [Template]({{ "/tags/template/" | prepend: site.baseurl }})
+- [Variable assignment]({{ "/tags/variable/" | prepend: site.baseurl }})
+
+You can read more about each type of tag in their respective sections.
+
+## Filters
+
+**Filters** change the output of a Liquid object or variable. They are used within double curly braces `{% raw %}{{ }}{% endraw %}` and [variable assignment]({{ "/tags/variable/" | prepend: site.baseurl }}), and are separated by a pipe character `|`.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{{ "/my/fancy/url" | append: ".html" }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{{ "/my/fancy/url" | append: ".html" }}
+```
+
+Multiple filters can be used on one output, and are applied from left to right.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{{ "adam!" | capitalize | prepend: "Hello " }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{{ "adam!" | capitalize | prepend: "Hello " }}

+

+When a non-boolean [data type]({{ "/basics/types/" | prepend: site.baseurl }}) is used in a boolean context (such as a conditional tag), Liquid decides whether to evaluate it as `true` or `false`.

 ## Summary
 

_basics/types.md

@@ -0,0 +1,157 @@
+---
+title: Types
+description: An overview of data types in the Liquid template language.
+---
+
+Liquid objects can be one of six types:
+
+- [String](#string)
+- [Number](#number)
+- [Boolean](#boolean)
+- [Nil](#nil)
+- [Array](#array)
+- [EmptyDrop](#emptydrop)
+
+You can initialize Liquid variables using [`assign`]({{ "/tags/variable/#assign" | prepend: site.baseurl }}) or [`capture`]({{ "/tags/variable/#capture" | prepend: site.baseurl }}) tags.
+
+## String
+
+Strings are sequences of characters wrapped in single or double quotes:
+
+```liquid
+{%- raw -%}
+{% assign my_string = "Hello World!" %}
+{% endraw %}
+```
+
+Liquid does not convert escape sequences into special characters.
+
+## Number
+
+Numbers include floats and integers:
+
+```liquid
+{%- raw -%}
+{% assign my_int = 25 %}
+{% assign my_float = -39.756 %}
+{% endraw %}
+```
+
+## Boolean
+
+Booleans are either `true` or `false`. No quotations are necessary when declaring a boolean:
+
+```liquid
+{%- raw -%}
+{% assign foo = true %}
+{% assign bar = false %}
+{% endraw %}
+```
+
+## Nil
+
+Nil is a special empty value that is returned when Liquid code has no results. It is **not** a string with the characters "nil".
+
+Nil is [treated as false]({{ "/basics/truthy-and-falsy/#falsy" | prepend: site.baseurl }}) in the conditions of `if` blocks and other Liquid tags that check the truthfulness of a statement.
+
+In the following example, if the user does not exist (that is, `user` returns `nil`), Liquid will not print the greeting:
+
+```liquid
+{%- raw -%}
+{% if user %}
+  Hello {{ user.name }}!
+{% endif %}
+{% endraw %}
+```
+
+Tags or outputs that return `nil` will not print anything to the page.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+The current user is {{ user.name }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+The current user is
+```
+
+## Array
+
+Arrays hold lists of variables of any type.
+
+### Accessing items in arrays
+
+To access all the items in an array, you can loop through each item in the array using an [iteration tag]({{ "/tags/iteration/" | prepend: site.baseurl }}).
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+<!-- if site.users = "Tobi", "Laura", "Tetsuro", "Adam" -->
+{% for user in site.users %}
+  {{ user }}
+{% endfor %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+  Tobi Laura Tetsuro Adam
+```
+
+### Accessing specific items in arrays
+
+You can use square bracket `[` `]` notation to access a specific item in an array. Array indexing starts at zero. A negative index will count from the end of the array.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+<!-- if site.users = "Tobi", "Laura", "Tetsuro", "Adam" -->
+{{ site.users[0] }}
+{{ site.users[1] }}
+{{ site.users[-1] }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+Tobi
+Laura
+Adam
+```
+
+### Initializing arrays
+
+You cannot initialize arrays using only Liquid.
+
+You can, however, use the [`split`]({{ "/filters/split/" | prepend: site.baseurl }}) filter to break a string into an array of substrings.
+
+## EmptyDrop
+
+An EmptyDrop object is returned if you try to access a deleted object. In the example below, `page_1`, `page_2` and `page_3` are all EmptyDrop objects:
+
+```liquid
+{%- raw -%}
+{% assign variable = "hello" %}
+{% assign page_1 = pages[variable] %}
+{% assign page_2 = pages["does-not-exist"] %}
+{% assign page_3 = pages.this-handle-does-not-exist %}
+{% endraw %}
+```
+
+### Checking for emptiness
+
+You can check to see if an object exists or not before you access any of its attributes.
+
+```liquid
+{%- raw -%}
+{% unless pages == empty %}
+  <h1>{{ pages.frontpage.title }}</h1>
+  <div>{{ pages.frontpage.content }}</div>
+{% endunless %}
+{% endraw %}
+```
+
+Both empty strings and empty arrays will return `true` if checked for equivalence with `empty`.

+title: Variations of Liquid
+description: An overview of the different installations of Liquid and how Liquid can change depending on where you're using it.
+---
+
+Liquid is a flexible, safe language, and is used in many different environments. Liquid was created for use in [Shopify](https://www.shopify.com) stores, and is also used extensively on [Jekyll](https://jekyllrb.com) websites. Over time, both Shopify and Jekyll have added their own objects, tags, and filters to Liquid. The most popular versions of Liquid that exist are **Liquid**, **Shopify Liquid**, and **Jekyll Liquid**.

+This site documents the latest version of **Liquid** including betas and release candidates — that is, Liquid as it exists outside of Shopify and Jekyll. If you download the Liquid repository or install it as a [gem](https://rubygems.org/gems/liquid), you will get access to whatever objects, tags, and filters are in the version of Liquid that you chose.
+
+## Shopify
+
+Shopify always uses the latest version of Liquid as a base, but Shopify adds a significant number of objects, tags, and filters to Liquid for use in merchants' stores. These include objects representing store, product, and customer information, and filters for displaying store data and manipulating storefront assets like product images.
+
+Shopify's version of Liquid is documented in the [Shopify developer documentation](https://shopify.dev/docs/themes/liquid/reference). If you want to try out Shopify's version of Liquid, you can create a development store through the [Shopify Partner Dashboard](https://help.shopify.com/en/partners/dashboard/managing-stores/development-stores).
+
+## Jekyll
+
+[Jekyll](https://jekyllrb.com) is a static site generator, a command-line tool that creates websites by merging templates with content files. Jekyll uses Liquid as its template language, and adds a few objects, tags, and filters. These include objects representing content pages, tags for including snippets of content in others, and filters for manipulating strings and URLs.
+
+Jekyll also powers [GitHub Pages](https://pages.github.com/), a web hosting service that lets you push a Jekyll installation to a GitHub repository and have the resulting website published. This website is built using GitHub Pages.
+
+Jekyll might not be using the latest version of Liquid. This means that the tags and filters listed on this site may not work in Jekyll. Often the Jekyll project will wait for a stable release of Liquid rather than using a beta or release candidate version. To see which version of Liquid is being used by Jekyll or GitHub Pages, check the **runtime dependencies** section of the gem page for [Jekyll](https://rubygems.org/gems/jekyll) or [GitHub Pages](https://rubygems.org/gems/github-pages).
+
+Jekyll's version of Liquid is documented in the [Liquid section of Jekyll's documentation](https://jekyllrb.com/docs/liquid/). If you want to try out Jekyll's version of Liquid, you can clone the Jekyll project or install Jekyll as a gem and test Liquid on a static site.

+title: Whitespace control
+description: An overview of controlling whitespace between code in the Liquid template language.
+---
+
+In Liquid, you can include a hyphen in your tag syntax `{% raw %}{{-{% endraw %}`, `{% raw %}-}}{% endraw %}`, `{% raw %}{%-{% endraw %}`, and `{% raw %}-%}{% endraw %}` to strip whitespace from the left or right side of a rendered tag.
+
+Normally, even if it doesn't print text, any line of Liquid in your template will still print a blank line in your rendered HTML:
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign my_variable = "tomato" %}
+{{ my_variable }}
+{% endraw %}
+```
+
+Notice the blank line before "tomato" in the rendered template:
+
+<p class="code-label">Output</p>
+```text
+{% assign my_variable = "tomato" %}
+{{ my_variable }}
+```
+
+By including a hyphen in your `assign` closing delimiter, you can strip the whitespace following it from the rendered template:
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign my_variable = "tomato" -%}
+{{ my_variable }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{% assign my_variable = "tomato" -%}
+{{ my_variable }}
+```
+
+If you don't want any of your tags to print whitespace, as a general rule you can add hyphens to both sides of all your tags (`{% raw %}{%-{% endraw %}` and `{% raw %}-%}{% endraw %}`):
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign username = "John G. Chalmers-Smith" %}
+{% if username and username.size > 10 %}
+  Wow, {{ username }} , you have a long name!
+{% else %}
+  Hello there!
+{% endif %}
+{% endraw %}
+```
+
+<p class="code-label">Output without whitespace control</p>
+```text
+{% assign username = "John G. Chalmers-Smith" %}

+
+### Controlling rounding
+
+`divided_by` produces a result of the same type as the divisor — that is, if you divide by an integer, the result will be an integer. If you divide by a float (a number with a decimal in it), the result will be a float.
+
+For example, here the divisor is an integer:
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{{ 20 | divided_by: 7 }}
+{% endraw %}

+```
+
+<p class="code-label">Output</p>
+```text
+{{ 20 | divided_by: 7.0 }}
+```
+
+### Changing variable types
+
+You might want to use a variable as a divisor, in which case you can't simply add `.0` to convert it to a float. In these cases, you can `assign` a version of your variable converted to a float using the `times` filter.
+
+In this example, we're dividing by a variable that contains an integer, so we get an integer:
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign my_integer = 7 %}
+{{ 20 | divided_by: my_integer }}

+```
+
+<p class="code-label">Output</p>
+```text
+{% assign my_integer = 7 %}
+{{ 20 | divided_by: my_integer }}
+```
+
+Here, we [multiply]({{ "/filters/times/" | prepend: site.baseurl }}) the variable by `1.0` to get a float, then divide by the float instead:
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign my_integer = 7 %}
+{% assign my_float = my_integer | times: 1.0 %}

+---
+
+Creates an array including only the objects with a given property value, or any [truthy]({{ "/basics/truthy-and-falsy/#truthy" | prepend: site.baseurl }}) value by default.
+
+In this example, assume you have a list of products and you want to show your kitchen products separately. Using `where`, you can create an array containing only the products that have a `"type"` of `"kitchen"`.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+All products:
+{% for product in products %}
+- {{ product.title }}
+{% endfor %}
+
+{% assign kitchen_products = products | where: "type", "kitchen" %}
+
+Kitchen products:
+{% for product in kitchen_products %}
+- {{ product.title }}
+{% endfor %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+All products:
+- Vacuum
+- Spatula
+- Television
+- Garlic press
+
+Kitchen products:
+- Spatula
+- Garlic press
+```
+
+Say instead you have a list of products and you only want to show those that are available to buy. You can `where` with a property name but no target value to include all products with a [truthy]({{ "/basics/truthy-and-falsy/#truthy" | prepend: site.baseurl }}) `"available"` value.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+All products:
+{% for product in products %}
+- {{ product.title }}
+{% endfor %}
+
+{% assign available_products = products | where: "available" %}
+
+Available products:
+{% for product in available_products %}
+- {{ product.title }}
+{% endfor %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+All products:
+- Coffee mug
+- Limited edition sneakers
+- Boring sneakers
+
+Available products:
+- Coffee mug
+- Boring sneakers
+```
+
+The `where` filter can also be used to find a single object in an array when combined with the `first` filter. For example, say you want to show off the shirt in your new fall collection.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign new_shirt = products | where: "type", "shirt" | first %}
+
+Featured product: {{ new_shirt.title }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+Featured product: Hawaiian print sweater vest

+

+

+```
+
+## raw
+
+Temporarily disables tag processing. This is useful for generating certain content that uses conflicting syntax, such as [Mustache](https://mustache.github.io/) or [Handlebars](https://handlebarsjs.com/).
+
+<p class="code-label">Input</p>

+  assign column_size = 'one-third'
+else
+  assign column_size = 'one-quarter'
+endcase %}
+{% endraw %}
+```
+
+Because any tag blocks opened within a `liquid` tag must also be closed within the same tag, use [`echo`](#echo) to output data.
+
+## echo {%- include version-badge.html version="5.0.0" %}
+
+Outputs an expression in the rendered HTML. This is identical to wrapping an expression in `{% raw %}{{{% endraw %}` and `{% raw %}}}{% endraw %}`, but works inside [`liquid`](#liquid) tags and supports [filters]({{ "/basics/introduction/#filters" | prepend: site.baseurl }}).
+
+<p class="code-label">Input</p>

+
+Insert the rendered content of another template within the current template.
+
+```liquid
+{%- raw -%}
+{% render "template-name" %}
+{% endraw %}
+```
+
+Note that you don't need to write the file's `.liquid` extension.
+
+The code within the rendered template does **not** automatically have access to the variables assigned using [variable tags]({{ "/tags/variable/" | prepend: site.baseurl }}) within the parent template. Similarly, variables assigned within the rendered template cannot be accessed by code in any other template.
+
+## render (parameters)
+
+Variables assigned using [variable tags]({{ "/tags/variable/" | prepend: site.baseurl }}) can be passed to a template by listing them as parameters on the `render` tag.
+
+```liquid
+{%- raw -%}
+{% assign my_variable = "apples" %}
+{% render "name", my_variable: my_variable, my_other_variable: "oranges" %}
+{% endraw %}
+```
+
+One or more objects can be passed to a template.
+
+```liquid
+{%- raw -%}
+{% assign featured_product = all_products["product_handle"] %}
+{% render "product", product: featured_product %}
+{% endraw %}
+```
+
+### with
+
+A single object can be passed to a template by using the `with` and optional `as` parameters.
+
+```liquid
+{%- raw -%}
+{% assign featured_product = all_products["product_handle"] %}
+{% render "product" with featured_product as product %}
+{% endraw %}
+```
+
+In the example above, the `product` variable in the rendered template will hold the value of `featured_product` from the parent template.
+
+### for
+
+A template can be rendered once for each value of an enumerable object by using the `for` and optional `as` parameters.
+
+```liquid
+{%- raw -%}
+{% assign variants = product.variants %}
+{% render "product_variant" for variants as variant %}
+{% endraw %}
+```
+
+In the example above, the template will be rendered once for each variant of the product, and the `variant` variable will hold a different product variant object for each iteration.
+
+When using the `for` parameter, the [`forloop`](https://shopify.dev/docs/themes/liquid/reference/objects/for-loops) object is accessible within the rendered template.
+
+## include
+
+_The `include` tag is deprecated; please use [`render`](#render) instead._
+
+Insert the rendered content of another template within the current template.
+
+```liquid
+{%- raw -%}
+{% include "template-name" %}
+{% endraw %}
+```
+
+The `include` tag works similarly to the [`render`](#render) tag, but it allows the code inside of the rendered template to access and overwrite the variables within its parent template. It has been deprecated because the way that it handles variables reduces performance and makes Liquid code harder to both read and maintain.
+
+Note that when a template is rendered using the [`render`](#render) tag, the `include` tag cannot be used within the template.

+Creates and outputs a new number variable with initial value `0`. On subsequent calls, it increases its value by one and outputs the new value.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% increment my_counter %}
+{% increment my_counter %}
+{% increment my_counter %}

+```text

+```
+
+Variables created using `increment` are independent from variables created using `assign` or `capture`.
+
+In the example below, a variable named "var" is created using `assign`. The `increment` tag is then used several times on a variable with the same name. Note that the `increment` tag does not affect the value of "var" that was created using `assign`.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% assign var = 10 %}
+{% increment var %}
+{% increment var %}
+{% increment var %}
+{{ var }}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{% assign var = 10 %}
+{% increment var %}
+{% increment var %}
+{% increment var %}
+{{ var }}
+```
+
+## decrement
+
+Creates and outputs a new number variable with initial value `-1`. On subsequent calls, it decreases its value by one and outputs the new value.
+
+<p class="code-label">Input</p>
+```liquid
+{%- raw -%}
+{% decrement variable %}
+{% decrement variable %}
+{% decrement variable %}
+{% endraw %}
+```
+
+<p class="code-label">Output</p>
+```text
+{% decrement variable %}
+{% decrement variable %}
+{% decrement variable %}
+```
+
+Like [increment](#increment), variables declared using `decrement` are independent from variables created using `assign` or `capture`.

-title: Introduction
----
-
-Liquid code can be categorized into [**objects**](#objects), [**tags**](#tags), and [**filters**](#filters).
-
-## Objects
-
-**Objects** tell Liquid where to show content on a page. Objects and variable names are denoted by double curly braces: `{% raw %}{{{% endraw %}` and `{% raw %}}}{% endraw %}`.
-
-
-<p class="code-label">Input</p>
-```liquid
-{% raw %}
-{{ page.title }}
-{% endraw %}
-```
-
-<p class="code-label">Output</p>
-```text
-Introduction
-```
-
-In this case, Liquid is rendering the content of an object called `page.title`, and that object contains the text `Introduction`.
-
-## Tags
-
-**Tags** create the logic and control flow for templates. They are denoted by curly braces and percent signs: `{% raw %}{%{% endraw %}` and `{% raw %}%}{% endraw %}`.
-
-The markup used in tags does not produce any visible text. This means that you can assign variables and create conditions and loops without showing any of the Liquid logic on the page.
-
-<p class="code-label">Input</p>
-```liquid
-{% raw %}
-{% if user %}
-  Hello {{ user.name }}!
-{% endif %}
-{% endraw %}
-```
-
-<p class="code-label">Output</p>
-```text
-Hello Adam!
-```
-
-Tags can be categorized into three types:
-
-- [Control flow]({{ "/tags/control-flow" | prepend: site.baseurl }})
-- [Iteration]({{ "/tags/iteration" | prepend: site.baseurl }})
-- [Variable assignments]({{ "/tags/variable" | prepend: site.baseurl }})
-
-You can read more about each type of tag in their respective sections.
-
-
-## Filters
-
-**Filters** change the output of a Liquid object. They are using within an output and are separated by a `|`.
-
-<p class="code-label">Input</p>
-```liquid
-{% raw %}
-{{ "/my/fancy/url" | append: ".html" }}
-{% endraw %}
-```
-
-<p class="code-label">Output</p>
-```text
-{{ "/my/fancy/url" | append: ".html" }}
-```

----
-title: Types
----
-
-Liquid objects can have one of six types:
-
-- [String](#string)
-- [Number](#number)
-- [Boolean](#boolean)
-- [Nil](#nil)
-- [Array](#array)
-
-You can initialize Liquid variables with the [assign]({{ "/tags/variable/#assign" | prepend: site.baseurl }}) or [capture]({{ "/tags/variable/#capture" | prepend: site.baseurl }}) tags.
-
-## String
-
-Declare a string by wrapping a variable's value in single or double quotes:
-
-```liquid
-{% raw %}
-{% assign my_string = "Hello World!" %}
-{% endraw %}
-```
-
-## Number
-
-Numbers include floats and integers:
-
-```liquid
-{% raw %}
-{% assign my_int = 25 %}
-{% assign my_float = 39.756 %}
-{% endraw %}
-```
-
-## Boolean
-
-Booleans are either `true` or `false`. No quotations are necessary when declaring a boolean:
-
-```liquid
-{% raw %}
-{% assign foo = true %}
-{% assign bar = false %}
-{% endraw %}
-```
-
-## Nil
-
-Nil is a special empty value that is returned when Liquid code has no results. It is **not** a string with the characters "nil".
-
-Nil is [treated as false]({{ "/basics/truthy-and-falsy" | prepend: site.baseurl }}) in the conditions of `if` blocks and other Liquid tags that check the truthfulness of a statement.
-
-In the following example, if the user does not exist (that is, `user` returns `nil`), Liquid will not print the greeting:
-
-```liquid
-{% raw %}
-{% if user %}
-  Hello {{ user.name }}!
-{% endif %}
-{% endraw %}
-```
-
-Tags or outputs that return `nil` will not print anything to the page.
-
-<p class="code-label">Input</p>
-```liquid
-{% raw %}
-The current user is {{ user.name }}
-{% endraw %}
-```
-
-<p class="code-label">Output</p>
-```text
-The current user is
-```
-
-## Array
-
-Arrays hold lists of variables of any type.
-
-### Accessing items in arrays
-
-To access all the items in an array, you can loop through each item in the array using an [iteration tag]({{ "/tags/iteration" | prepend: site.baseurl }}).
-
-<p class="code-label">Input</p>
-```liquid
-{% raw %}
-<!-- if site.users = "Tobi", "Laura", "Tetsuro", "Adam" -->
-{% for user in site.users %}
-  {{ user }}
-{% endfor %}
-{% endraw %}
-```
-
-<p class="code-label">Output</p>
-```text
-{% raw %}
-Tobi Laura Tetsuro Adam
-{% endraw %}
-```
-
-### Accessing specific items in arrays
-
-You can use square bracket `[` `]` notation to access a specific item in an array. Array indexing starts at zero.
-
-<p class="code-label">Input</p>
-```liquid
-{% raw %}
-<!-- if site.users = "Tobi", "Laura", "Tetsuro", "Adam" -->
-{{ site.users[0] }}
-{{ site.users[1] }}
-{{ site.users[3] }}
-{% endraw %}
-```
-
-<p class="code-label">Output</p>
-```text
-Tobi
-Laura
-Adam
-```
-
-### Initializing arrays
-
-You cannot initialize arrays using only Liquid.
-
-You can, however, use the [split]({{ "/filters/split" | prepend: site.baseurl }}) filter to break a string into an array of substrings.
