-##### Needs cookies:
+##### Cookies Required:
+
+Cookies are essential for the proper functioning of some service providers.
+It is imperative to maintain an active session, typically achieved by logging into your account.
+
+When running the g4f package locally, the package automatically retrieves cookies from your web browser using the `get_cookies` function. However, if you're not running it locally, you'll need to provide the cookies manually by passing them as parameters using the `cookies` parameter.
 
-Many providers need cookies to work.
-In Bing you need a session, where you have passed the captcha.
-And in others providers you have to log-in into your account.
-If you run the g4l package locally,
-cookies from your browsers are read with `get_cookies`.
-Else you have pass them in the parameter `cookies`:

-##### Async support:
+##### Async Support:
 
-Run providers `async` to improve speed / performance.
-The full execution time corresponds to the execution time of the slowest provider.
+To enhance speed and overall performance, execute providers asynchronously. The total execution time will be determined by the duration of the slowest provider's execution.
