-The developmental versions of the library are available through Azure DevOps as part of the Continuous Integration builds after each Github commit.
+The developmental versions of the library are now available as **pre-release** on Nuget (with `-dev` in the version number)
 
-You can access these versions for testing in your program by going to our [private nuget feeds](https://dev.azure.com/wiz0u/WTelegramClient/_artifacts/feed/WTelegramClient/NuGet/WTelegramClient),
-click on button "Connect to feed" and follow the steps to setup your dev environment.
-After that, you should be able to see/install the pre-release versions in your Nuget package manager and install them in your application. *(make sure you enable the **pre-release** checkbox)*
+So make sure you tick the checkbox "Include prerelease" in Nuget manager and/or navigate to the Versions list then select the highest `x.x.x-dev.x` version to install in your program.

 3) Did you use `await` with every Client methods?

 4) Is your program ending immediately instead of waiting for Updates?  
-Your program must be running/waiting continuously in order for the background Task to receive and process the Updates. So make sure your main program doesn't end immediately. For a console program, this is typical done by waiting for a key or some close event.

 5) Is every Telegram API call rejected? (typically with an exception message like `AUTH_RESTART`)  
-The user authentification might have failed at some point (or the user revoked the authorization). It is therefore necessary to go through the authentification again. This can be done by deleting the WTelegram.session file, or at runtime by calling `client.Reset()`
