+
+Scans are the heart of kilometer tracking - they connect [runners](../runners) with the distance covered.
+There are two types of scans in the system: "Fixed Distance Scans" and "Track Scans".
+
+Fixed Distance Scans can only be created by users in the runner system and assign a fixed distance to a runner.
+This is particularly useful when runners have lost cards halfway or receive a distance bonus for other reasons.
+
+Track Scans, on the other hand, can only be generated by a scanning station scanning the code of a runner's card, thus creating a new scan.
+Track Scans are always linked to a runner and a [track](../tracks), from which the distance is derived.
+
+## Creating
+
+> You can only create Fixed Distance Scans in the runner system.
+
+To create a new scan, open the `Scans` page in the runner system.
+You can create a new scan using the `Create Scan` button.
+You must assign a runner and a distance in meters to the scan.
+Once you have provided all the information, you can create the scan using the `Create` button.
+
+## Editing
+
+To edit a scan, you can click the `Details` button for the desired scan in the scan overview.
+
+### Fixed Distance Scans
+
+In the scan detail view of Fixed Distance Scans, you can adjust the validity, runner, and distance.
+When you are done, simply click `Save Changes`.
+
+### Track Scans
+
+In the scan detail view of Track Scans, you can only adjust the validity - all other values are fixed in the system.
+When you are done, simply click `Save Changes`.
+
+## Deleting
+
+You can delete a scan either from the scan overview or the scan detail view.
+We generally recommend deactivating scans rather than deleting them to prevent human errors.
+
+### In the Scan Overview
+
+Click the `Delete` button for the desired scan.
+You will then be asked whether you really want to delete the scan or cancel.
+
+### In the Scan Detail View
+
+Click the `Details` button for the desired scanning station.
+At the top of the page, there is now a `Delete Scan` button.
+You will then be asked whether you really want to delete the scanning station or cancel.
