+# Expo Login for GitHub Actions
+
+Authenticate the current workflow to publish new versions or create new builds.
+It works relatively simple, you define the Expo credentials and this action will do the rest.
+
+## Usage
+
+First you need to define the [secrets listed below][#secrets] through [GitHub secrets](https://developer.github.com/actions/managing-workflows/storing-secrets/).
+After that, you can add the action below in your workflow.
+
+```hcl
+action "Login with Expo" {
+  uses = "bycedric/ci-expo/login@master"
+  secrets = ["EXPO_USERNAME", "EXPO_PASSWORD"]
+}
+```
+
+### Secrets
+
+* `EXPO_USERNAME` - **Required**. The email address or username of the Expo account.
+* `EXPO_PASSWORD` - **Required**. The password of the Expo account.
+
+## License
