 ### Injecting existing token into BoxOAuth
 
-If you already have an access token and refresh token, you can initialize `BoxOAuth` with them.
-You can achieve this by feeding `BoxOAuth` with token storage containing the token.
-This can be useful when you want to reuse the token between runs of your application.
+If you already have an access token and refresh token, you can inject them into the `BoxOAuth` token storage
+to avoid repeating the authentication process. This can be useful when you want to reuse the token
+between runs of your application.
 
 ```c#
 var accessToken = new AccessToken
 {
     AccessTokenField = "<ACCESS_TOKEN>",
     RefreshToken = "<REFRESH_TOKEN>"
 };
-var tokenStorage = new InMemoryTokenStorage();
-await tokenStorage.StoreAsync(accessToken);
-var config = new OAuthConfig(clientId: "YOUR_CLIENT_ID", clientSecret: "YOUR_CLIENT_SECRET", tokenStorage: tokenStorage);
-var auth = new BoxOAuth(config: config);
