+## Generate icons
+
+It's best to use the provided `generate_icons.sh` script to generate all necessary icons for your website. This script requires ImageMagick, that you will need to install separately.
+
+For the best results, place your logo in svg format inside the `static` directory of your website, rename it to `logo.svg` and then call `./themes/hugo-ficurinia/generate_icons.sh static/logo.svg`.
+
+The script will take care of generating all the icons you need.
+
+Finally, make sure to edit your config.toml to include the following:
+
+```toml
+# ...
+[params]
+    logo = "/logo.svg"
+    favicon = "/favicon.png"
+    faviconIco = "/favicon.ico"
+    appletouch = "/apple-touch-icon.png"
+    svgicon = "/logo.svg"
+    # ...
+```
+
 ## Inject custom content
 
 Ficurinia supports injecting custom content into the theme. There are several files you can create in `layouts/partials/inject` that will be included inside the theme in different places.
