Make sure to allow NuGet Package Restore in VS (Tools > Options > Package Manager). The first buid of the project will take quite a while, be patient, it will finish at some point.
Upon build a web.config file will be copied into the `OurUmbraco.Site` project which you can use in the following step.
Restore the database to SQL Server 2008R2 (won't work on earlier version) and update the connection strings (`umbracoDbDSN` and `Marketplace.Data.Properties.Settings.ourConnectionString`) in `OurUmbraco.Site/web.config`.
To log in, try `root` / `Not_A_Real_Password` for the backoffice and `member423@non-existing-mail-provider.none` / `Not_A_Real_Password` for the frontend.
##Projects
If the projects section seems empty then that's because you need to rebuild the Examine indexes for it through the Developer section of Umbraco
##Documentation
If the documentation section seems empty then that's because you need to download the documentation, look for the the `Github Documentation` tab in the dashboards in the Developer section of Umbraco and use the `Get Docs!!` button.
