+# Image Styling User Guide
+
+This user guide will show you how to change the image styles in QGIS symbology to enhance the quality and realism of your images.
+
+## Step 1: Open QGIS and Load Your Project

+To get started, open QGIS and load your existing project, or simply open your QGIS project (e.g. Malawi 2) with QGIS.
+
+# Step 2: Open the Layer Properties
+
+In the Layers panel, right-click on the layer for which you want to change the symbology and select the 1️⃣ `Properties`. This will open the Layer Properties dialog box.

+# Step 3: Open the Symbology Tab
+
+In the Layer Properties dialog box, click on the 1️⃣ `Symbology` tab on the left side. This will open the Symbology settings. In the Symbology settings, locate the settings for contrast enhancement. In the contrast enhancement dropdown, select the 2️⃣ `Stretch to MinMax` option. This will adjust the contrast of the image to make it more visually appealing.
