+# Illustrator Template Guide
+
+This Guide explains how to properly use the Adobe Illustrator Template for Lucide.
+
+>Attention: Even though it is unlikely the template can be outdated or not 100% correct. Please check the Icon Design Guide before you start working with the template to ensure integrity with the Lucide icon pack.
+
+## General Workflow
+
+The Illustrator template is created following guidelines from the [Icon Design Guide](ICON_DESIGN_GUIDE.md).
+
+**Workflow:**
+
+1. Open the Document which can be found under __*/docs/templates/illustrator_template.ai*__ .
+
+2. You can now remove the content from the example logo layer ("Draw") and start creating.
+
+3. Verify that you follow the [Icon Design Guidelines](ICON_DESIGN_GUIDE.md).
+
+4. Before you export the file as an SVG make sure to check that you followed the guidelines and remove all unecessary layers (especially "Padding" and "Grid").
+
+5. Export the file with the export menu under: `Export > Export As..` than safe the file as SVG. Select the following options in the SVG Options dialog:
+
+![SVG export options in Illustrator](images/illustrator-svg-options.png?raw=true "Setting Page Size")
+
+After that, double check that the [code conventions and SVG global attributes](https://github.com/lucide-icons/lucide/blob/master/docs/ICON_DESIGN_GUIDE.md#code-conventions) are correct.
+
+7. Minify paths with [SVGOMG](https://jakearchibald.github.io/svgomg/).
