+# Map Annotations in Mergin Maps Mobile App
+[[toc]]
+
+Map annotations can be used to draw something on the map, in addition to the regular field collection of [features](../mobile-features/).
+
+## Set up map annotations in QGIS project
+
+Map annotations need to be enabled in QGIS when [preparing your <MainPlatformName /> project](../../gis/features/#map-annotations).
+
+1. Open your <MainPlatformName /> project in QGIS
+2. Navigate to **Project** > **Properties** 
+   ![QGIS Project Properties](../../gis/qgis-project-properties.jpg "QGIS Project Properties")
+
+3. In the <MainPlatformName /> tab, check the **Enable map annotations layer** option.
+   ![Enable map annotations in QGIS Mergin Maps project](../../gis/features/project-map-annotations.jpg "Enable map annotations in QGIS Mergin Maps project")
+
+   You can also change the colour set to define the colours that will be available in the <MobileAppNameShort />.
+
+4. Save the changes. 
+
+   A new layer named `map_annotations_layer` will be added to the project. This layer is used to store the annotations.
+
+5. Save and synchronise your project!
+
+::: tip 
+If you do not see this option in the **Project properties**, check for [plugin upgrades](../../setup/install-mergin-maps-plugin-for-qgis/#plugin-upgrade).
+:::
+
+## Map annotations in the mobile app
+To use map annotations in the <MobileAppNameShort />, make sure they are [enabled in the project](#set-up-map-annotations-in-qgis-project).
+
+1. Tap the **Map annotations** button
+   ![Map annotations button in Mergin Maps mobile app](./mobile-map-annotations-button.jpg "Map annotations button in Mergin Maps mobile app")
+
+2. The **Annotations** bar appears.
+   - Draw your annotations on the map by freehand or using a stylus.
+
+   You choose from 7 annotation colours. The colour set can be changed in the [project properties](#set-up-map-annotations-in-qgis-project) in QGIS.
+   ![Map annotations in Mergin Maps mobile app](./mobile-map-annotations.jpg "Map annotations in Mergin Maps mobile app")
+
+   - Made a mistake? Use the **Eraser** button to remove your annotations.
+   ![Erase map annotations in Mergin Maps mobile app](./mobile-map-annotations-eraser.jpg "Erase map annotations button in Mergin Maps mobile app")
+
+4. Sync your changes to <MainPlatformNameLink />.
+
+   In QGIS, the annotations will be displayed in the `map_annotations_layer`.
