# Configuration Steps

After connecting to a database, you will be presented with configuration steps before you can begin working with your data. The configuration involves three steps:

1. [Configure source](https://docs.editable.io/getting-data-into-editable/connect-to-data/configuration-steps/configure-source)
2. [Configure columns](https://docs.editable.io/getting-data-into-editable/connect-to-data/configuration-steps/configure-columns)
3. [Configure SCDs (optional)](https://docs.editable.io/getting-data-into-editable/connect-to-data/configuration-steps/configure-type-2-scds-optional)

We'll look at them one by one in the upcoming sections.

If you have not connected to an existing database but have [created a table using EDITable](https://docs.editable.io/getting-data-into-editable/create-a-table), the configuration steps are as follows:

1. Configure Source: When you select and add a data source to create a table, you are configuring the source. 
2. Configure Columns: Once your data is loaded into EDITable, you can manage the column properties using the [Manage Columns](https://docs.editable.io/working-with-editable/manage-columns) menu.
3. Configure SCDs: Adding Slowly Changing Dimensions (SCDs) is optional and can be set up for specific tables that require and support them.
