-* Select the 'Type of laterals:'
-* Upload a CSV file
-* Set the time units used in your CSV file (hours, minutes, or seconds). The default is minutes (mins), because this is the time unit that is used in the 3Di spatialite
-* If the option 'Interpolate' is checked, the value between time steps will be linearly interpolated. 
-* Check the option 'Overrule single laterals', to exclude certain laterals in your model
+You can switch the 1D and/or the 2D laterals on and off by checking or unchecking the checkbox for the group.
+
+If the option 'Interpolate' is checked, the value between time steps will be linearly interpolated. If not, the value will be constant until the next time frame starts.
+
+.. note:: 
+
+	If the box *Use 1D laterals from the simulation template* is checked and *Upload 1D laterals* is also checked, the uploaded laterals are added to the laterals already present in the simulation template. The same applies to 2D laterals.
