 ### Deploy Default Build
 
-A default solution (sppkg) file for this sample exists in the [deployment](./deployment) folder. This sppkg will need to be deployed in the tenants site collection app catalog with the `Make this solution available to all sites in teh organization` option selected. By doing so the solution will be available in every site collection in the tenant, however since the solution has not been enabled for SharePoint deployment it will not be seen anywhere in the SharePoint user interface. Instead, the Teams manifest that is included in the package will be deployed which creates a Personal App that can then be pinned to the left rail in Teams and, if desired, audience targeted to specific user groups using the [Manage app setup policies in Microsoft Teams](https://docs.microsoft.com/en-us/MicrosoftTeams/teams-app-setup-policies).

 When complete the solution will be running in the root site collection and so the four custom lists that are created and permissions for the various features of the solution will come from the configuration of that root site collection. If you wish to have a specific, custom site collection, host the solution you can still use this sppkg file but you will need to skip step 4 below that sync's the packaged manifest to teams. Instead, you will need to review the [Custom Manifest](./Custom_Manifest) documentation to create an load an alternative manifest.
