 ## Getting Started
 
+### I have a `vale.ini` already
+
 To get started, add the package to your configuration file (as shown below) and then run `vale sync`.
 
 ```ini
 StylesPath = styles # Use your normal style path here.
 Packages = https://github.com/krystal/vale-package/releases/latest/download/vale.zip
 ```
 
+### Add Vale to a project
+
+Create a `.vale.ini` at the project's root:
+```ini
+StylesPath = vale-styles  # Location of styles directory
+MinAlertLevel = suggestion # Options: suggestion, warning, error
+Packages = https://github.com/krystal/vale-package/releases/latest/download/vale.zip
+
+[*.md]  # Apply to markdown files
+BasedOnStyles = Krystal
+```
+
 See [Vale's documentation on packages](https://vale.sh/docs/topics/packages/) for more information.
+
+### Setup whilst the Vale package is a private repository
+
+Before we make this Vale package public, it cannot be downloaded via `vale sync` with the above config. We'll use the GitHub CLI to simplify grabbing an auth token. You may generate a `PAT` and use that instead if you wish.
+
+> [!TIP]
+> Install the [GitHub CLI](https://cli.github.com/) and authenticate it first.
+
+```shell
+curl -L -H "Authorization: token $(gh auth token)" \
+     -o vale-package-0.1.0.zip \
+     https://github.com/krystal/vale-package/archive/refs/tags/v0.1.0.zip
+```
+
+Add `vale-package.zip` to `.gitignore`.
+
+Create `.vale.ini`.
+
+```ini
+StylesPath = vale-styles  # Location of styles directory
+MinAlertLevel = suggestion # Options: suggestion, warning, error
+Packages = vale-package-0.1.0.zip
+
+[*.md]  # Apply to markdown files
+BasedOnStyles = Krystal
+```
+
+Run `vale sync`.
