+To add authentication to your app using Asgardeo, you will first need to [create an application](https://wso2.com/asgardeo/docs/guides/applications/register-mobile-app/) in the Asgardeo console. If you don't have an Asgardeo account, [you can signup for one free](https://asgardeo.io/signup).
+
+After creating an application, take note of the configuration values listed in the **Quick Start** and **Info** tabs. You will be using those values as follows.
+
+```js
+export const config = {
+  issuer: 'https://api.asgardeo.io/t/<your_org_name>/oauth2/token',
+  clientId: '<your_application_id>',
+  redirectUrl: '<your_appAuthRedirectScheme>://example',
+  scopes: ['openid', 'profile']
+};
+
+// Log in to get an authentication token
+const authState = await authorize(config);
+
+// Refresh token
+const refreshedState = await refresh(config, {
+  refreshToken: authState.refreshToken,
+});
+
+// Revoke token
+await revoke(config, {
+  tokenToRevoke: refreshedState.refreshToken
+});
+
+// End session
+await logout(config, {
+  idToken: authState.idToken,
