+# Example
+
+This is an example extension that can be used as a starting point to develop
+new extensions.
+
+To create a new extension named my-extension type the following:
+
+    cp -R example ~/my-extension
+    cd ~/my-extension
+    ./init.sh my-extension
+
+To compile the extension:
+
+    meson build
+    ninja -C build
+
+To install:
+
+    sudo ninja -C install
+
+After installing the extension, start gThumb and activate it from the
+Preferences dialog.
+
+If you think your extension can be useful to others as well, add it to
+the extensions list available at <https://wiki.gnome.org/Apps/Gthumb/extensions>.
