 ## Package Notes
+
 Facebook hides Messenger downloads behind a timestamped download URL that is generated by a request to a canonical URL. While it seems possible to influence which software version is served (namely with `User-Agent` spoofing), the resulting URL is obfuscated and implements signature matching to prevent tampering, which makes reverse engineering of the server's behavior difficult. Therefore, this package will only support the latest available version, and should be treated similarly to packages with a non-versioned download URL.
 
 This means the installer binary's checksum will periodically change, and a newly released software version will break this package version. Consequently, FOSS users should generally consider older package versions to be obsolete and unsupported. Obsolete package versions may be unlisted if the Chocolatey CDN has not cached the download before obsoletion.

 ## Update

 This package should be automatically updated by the [Chocolatey Automatic Package Updater Module](https://github.com/majkinetor/au). If it is outdated by more than a few days, please [open an issue](https://github.com/brogers5/chocolatey-package-messenger/issues).
 
 AU expects the parent directory that contains this repository to share a name with the Nuspec (`messenger`). Your local repository should therefore be cloned accordingly:
+
 ```shell
 git clone [email protected]:brogers5/chocolatey-package-messenger.git messenger
 ```
 
 Alternatively, a junction point can be created that points to the local repository (preferably within a repository adopting the [AU packages template](https://github.com/majkinetor/au-packages-template)):
+
 ```shell
 mklink /J messenger ..\chocolatey-package-messenger
