+Importing SVG images with text
+------------------------------
+
+As the SVG library used in Godot doesn't support rasterizing text found in SVG
+images, text must be converted to a path first. Otherwise, text won't appear in
+the rasterized image.
+
+There are two ways to achieve this in a non-destructive manner, so you can keep
+editing the original text afterwards:
+
+- Select your text object in Inkscape, then duplicate it in place by pressing
+  :kbd:`Ctrl + D` and use **Path > Object to Path**. Hide the original text
+  object afterwards using the **Layers and Objects** dock.
+- Use the Inkscape command line to export a SVG from another SVG file with text
+  converted to paths:
+
+::
+
+    inkscape --export-text-to-path --export-filename svg_with_text_converted_to_path.svg svg_with_text.svg
