-
-### Primer on priorities
-
-All navigation menu items have an internal priority value that determines its order in the navigation.
-Lower values means that the item will be higher up in the menu. The default for pages is `999` which puts them last.
-However, some pages are autoconfigured to have a lower priority, for example, the `index` page defaults to a priority of `0`,
-
-#### Basic syntax for changing the priorities
-
-The cleanest way is to use the list-style syntax where each item will get the priority calculated according to its position in the list, plus an offset of `500`.
-The offset is added to make it easier to place pages earlier in the list using front matter or with explicit priority settings.
-
-```php
-[
-    'readme', // Gets priority 500
-    'installation', // Gets priority 501
-    'getting-started', // Gets priority 502
-]
-```
-
-#### Explicit syntax for changing the priorities
-
-You can also specify explicit priorities by adding a value to the array key:
-
-```php
-[
-    'readme' => 10, // Gets priority 10
-    'installation' => 15, // Gets priority 15
-    'getting-started' => 20, // Gets priority 20
-]
-```
-
-You can also combine these options if you want:
-
-```php
-[
-    'readme' => 10, // Gets priority 10
-    'installation', // Gets priority 500
-    'getting-started', // Gets priority 501
-]
-```
-
-You can also set the priority of a page directly in the front matter. This will override any dynamically inferred or
-config defined priority. While this is useful for one-offs, it can make it harder to reorder items later on.
-It's up to you which method you prefer to use. This setting can be used both for the navigation menu and the sidebar.
-
-```markdown
----
-navigation:
-    priority: 25
----
-```
-
-#### Changing the menu item labels
-
-Hyde makes a few attempts to find a suitable label for the navigation menu items to automatically create helpful titles.
-You can override the label using the `navigation.label` front matter property.
-
-From the Hyde config you can also override the label of navigation links using the by mapping the route key
-to the desired title. Note that the front matter property will take precedence over the config property.
-
-```php
-// filepath config/hyde.php
-'navigation' => [
-    'labels' => [
-        'index' => 'Start',
-        'docs/index' => 'Documentation',
-    ]
-]
-```
-
-#### Excluding Items (Blacklist)
-
-Sometimes, especially if you have a lot of pages, you may want to prevent links from showing up in the main navigation menu.
-To remove items from being automatically added, simply add the page's route key to the blacklist.
-As you can see, the `404` page has already been filled in for you.
-
-```php
-// filepath config/hyde.php
-'navigation' => [
-    'exclude' => [
-        '404'
-    ]
-]
-```
-
-You can also specify that a page should be excluded by setting the page front matter.
-
-```markdown
----
-navigation:
-    hidden: true
----
-```
-
-#### Adding Custom Navigation Menu Links
-
-You can easily add custom navigation menu links similar how we add Authors. Simply add a `NavItem` model to the `navigation.custom` array.
-
-When linking to an external site, you should use the `NavItem::forLink()` method facade. The first two arguments are the
-destination and label, both required. Third argument is the priority, which is optional, and defaults to 500.
-
-```php
-// filepath config/hyde.php
-use Hyde\Framework\Features\Navigation\NavItem;
-
-'navigation' => [
-    'custom' => [
-        NavItem::forLink('https://github.com/hydephp/hyde', 'GitHub', 200),
-    ]
-]
-```
-
-Simplified, this will then be rendered as follows:
-
-```html
-<a href="https://github.com/hydephp/hyde">GitHub</a>
-```
-
-#### Automatic navigation menu dropdowns
-
-HydePHP has a neat feature to automatically place pages in dropdowns based on subdirectories.
-
-For pages that can be in the main site menu, ths feature needs to be enabled in the `hyde.php` config file.
-
-```php
-// filepath config/hyde.php
-
-'navigation' => [
-    'subdirectories' => 'dropdown',
-],
-```
-
-Now if you create a page called `_pages/about/contact.md` it will automatically be placed in a dropdown called "About".
-
-#### Automatic documentation sidebar grouping
-
-This feature works similarly to the automatic navigation menu dropdowns, but instead place the sidebar items in named groups.
-This feature is enabled by default, so you only need to place your pages in subdirectories to have them grouped.
-
-For example: `_docs/getting-started/installation.md` will be placed in a group called "Getting Started".
