On your Appframe Web installation there should be a menu with various developer commands such as new app, edit app, article list, edit sidebar and edit site. These commands are typically located on the profile dropdown in the sidebar.
To get a basic app up and running all you have to do is to add and configure a data source (remember to add columns) and write markup that references that data source.
A powerful tool, espescially if you are new to Appframe Web 2016 is the Code Builder. This is a tool that based on the specific data sources for your app can generate usable markup.
DB Updater allows you generate SQL updates in development database and apply them in destination database. DB Updater is only available in Pims365-based Appframe installations so far.
In a source solution reach into /api/sqlupdate/listentome.sql for example https://stage.pims365.no/api/sqlupdate/listentome.sql. This will generate SQL that you can run in your solution. After running generated script your database will be configures to listen to the source database as a compatibility source.
Site setup is where global settings for your whole site are set up. For most appframe installations the changes you need to make here should be minimal. Changing the sidebar or mega menu is not done here. That is done with a edit sidebar or edit mega menu commannd.
