+# Contribution guidelines
+
+In case your interested in contributing to the macOS defaults website, please respect the following rules.
+
+## Creating the page
+
+- Each page references one command.
+- The page should be a `.md` file in one folder inside `docs`.
+- Do not create a new folder for one page only. At least 3 pages are needed before considering creating a folder. Use the `misc` folder in case you can't find one.
+- The filename should be the lowercased command key. Examples:
+  - `defaults write com.apple.dock "autohide" -bool "true"` is `autohide.md`
+  - `defaults write NSGlobalDomain "AppleSpacesSwitchOnActivate" -bool "true"` is `applespacesswitchonactivate.md`
+  - `defaults write com.apple.dock "scroll-to-open" -bool "true"` is `scroll-to-open.md`
+
+## Page content
+
+> [!IMPORTANT]
+> All infos must be unopionated.
+>
+> Avoid words like "enable"/"disable", "allow"/"disallow", "turn on"/"turn off"...
+> Prefer "toggle", "switch", "set"...
+
+### Meta informations
+
+Some meta informations are required to ensure proper SEO and social media sharing. VitePress uses [Frontmatter](https://vitepress.dev/guide/frontmatter) to fill in these info.
+
+::: details Complete example:
+
+```md
+---
+title: Autohide animation time | Dock
+description: Change the Dock opening and closing animation times.
+head:
+  - - meta
+    - property: 'og:title'
+      content: macOS defaults > Dock > Autohide animation time
+  - - meta
+    - property: 'og:description'
+      content: Change the Dock opening and closing animation times.
+---
+```
+
+:::
+
+The following fields are mandatory.
+
+#### Title
+
+> [!IMPORTANT]
+> The page title must be 1 to 5 words.
+
+| Field name | Format                                  | Usage        |
+| ---------- | --------------------------------------- | ------------ |
+| `title`    | `${title} \| ${folder}`                 | SEO          |
+| `og:title` | `macOS defaults > ${folder} > ${title}` | Social Media |
+
+#### Description
+
+> [!IMPORTANT]
+> The page description should be 1 sentence.
+
+| Field name       | Format            | Usage        |
+| ---------------- | ----------------- | ------------ |
+| `description`    | Ending with a dot | SEO          |
+| `og:description` | Ending with a dot | Social Media |
+
+### Heading section
+
+#### Page title
+
+> [!IMPORTANT]
+> Title must be 1 to 5 words.
+
+It's used to generate the sidebars and the Table of contents.
+
+##### Example:
+
+```md
+# Page title
+```
+
+#### Description
+
+Example:
+
+```md
+Describe what the command is doing.
+
+Please add some context if it is helpful.
+
+Specify if the command cannot be activated directly:
+
+> ⚠️ A restart of your Mac is required to apply these changes.
+```
+
+Take a look at the [mouse acceleration command](/mouse/linear.md#acceleration) for a well written complete description.
+
+#### Version support
+
+Only include the versions you tested. Sort the versions in reverse release date order.
+
+##### Example:
+
+```md
+**Tested on macOS:**
+
+- Sequoia
+- Sonoma
+```
+
+#### Command parameter
+
+`defaults` commands can take various parameter types:
+
+- `bool`
+- `int`
+- `float`
+- `string`
+- `array`
+
+It is possible to find the type of a command with the `defaults` CLI using:
+
+```bash
+defaults read-type ${domain} ${key}
+```
+
+When the possible values are limited, please list them.
+
+##### Example:
+
+```md
+**Parameter type**: int
+**Accepted parameter values**:
+
+- 0
+- 2
+- 3
+```
+
+#### Command requirements
+
+Some commands have prerequisites. List them in this section.
+
+##### Example:
+
+```md
+## Requirements
+
+- [`com.apple.dock autohide`](/dock/autohide.md#set-to-true) must be set to `true`
+```
+
+### Command demos
+
+At least 4 sections are needed:
+
+- Set the domain's key to some value
+- Set the domain's key to the default value
+- Read current domain's key value
+- Reset the domain's key value
+
+Each of them contain a bash command the user can copy. It should use double quotes around the key for stability.
+
+The command should be self-sufficient, usually there is a `killall ${app_name}` command that is needed.
+
+The first two sections contain a description of what the command does.
+Avoid direct parameter values such as `0` as type could be wrongly interpreted, always prefer `-${type} "${value}"` with quoted value.
+These can and should when possible include a screenshot or a video to demo what the command does.
+
+::: details Example with images demos:
+
+````md
+## Set to `36`
+
+Dock icon size of 36 pixels.
+
+```bash
+defaults write com.apple.dock "tilesize" -int "36" && killall Dock
+```
+
+<img
+  src="./images/tilesize/36.png"
+  alt="Example output with value set to 36"
+  width="740" height="463" style="height: auto"
+/>
+
+## Set to `48` (default value)
+
+Dock icon size of 48 pixels.
+
+```bash
+defaults write com.apple.dock "tilesize" -int "48" && killall Dock
+```
+
+<img
+  src="./images/tilesize/48.png"
+  alt="Example output with value set to 48"
+  width="740" height="463" style="height: auto"
+/>
+
+## Read current value
+
+```bash
+defaults read com.apple.dock "tilesize"
+```
+
+## Reset to default value
+
+```bash
+defaults delete com.apple.dock "tilesize" && killall Dock
+```
+````
+
+:::
+
+Take a look at the [Dock's autohide delay command for video examples](https://github.com/yannbertrand/macos-defaults/edit/main/docs/dock/autohide-delay.md).
+
+### macOS UI Alternative
+
+Majority of commands can be updated from macOS UI. When possible, please include the way to do it.
+
+Some macOS System Settings can be directly accessed via special links. E.g. <a href="x-apple.systempreferences:com.apple.preference.dock?Dock">Access Dock settings</a>. You can find this URL with the Script Editor App using this script:
+
+```applescript
+tell application "System Settings"
+	set myIds to the id of every pane
+	set myAnchors to anchors of current pane
+end tell
+```
+
+##### Example:
+
+```md
+## Set value from UI
+
+1. <a href="x-apple.systempreferences:com.apple.preference.dock?Dock">Access Dock settings from macOS UI</a>
+2. Set "Position on the screen" dropdown value
+```
+
+### Complete page example
+
+Here is a complete template you can copy:
