-# prettier-config
-Vertex's shared config for Prettier.
+# @vertexvis/prettier-config
+
+Vertex's shared Prettier config.
+
+## Usage
+
+This is based on [Shared
+Configurations](https://prettier.io/docs/en/configuration.html#sharing-configurations)
+in Prettier's documentation.
+
+1. Remove any existing `.prettierrc` files.
+2. Install the config.
+  ```
+  yarn add --dev @vertexvis/prettier-config
+
+  # or
+
+  npm install -D @vertexvis/prettier-config
+  ```
+3. Update your `package.json` to reference the shared config.
+  ```
+  "prettier": "@vertexvis/prettier-config",
+  ```
+
+## Overrides
+
+If you'd like to override any of the default settings, add a `.prettierrc.js`
+file in your project with any settings that you'd like to change:
+
+```js
+module.exports = {
+  ...require("@vertexvis/prettier-config"),
+  semi: false,
+};
+```
+
+## Publishing to NPM
+
+To publish a release to NPM, run `yarn version` to update the major or minor
+version. Commit your changes and open a PR. Once the PR is merged, the new
+version will be published to NPM.
