+## Custom services
+
+Custom services are small VueJs component (see `src/components/services/`) that add little features to a classic, "static", dashboard item. It should be very simple.
+A dashboard can contain a lot of items, so performance is very important. 
+
+The [`Generic`](https://github.com/bastienwirtz/homer/blob/main/src/components/services/Generic.vue) service provides a typical card layout which
+you can extend to add specific features. Unless you want a completely different design, extended the generic service is the recommended way. It gives you 3 [slots](https://vuejs.org/v2/guide/components-slots.html#Named-Slots) to extend: `icon`, `content` and `indicator`. 
+Each one is **optional**, and will display the usual information if omitted.
+
+Each service must implement the `item` [property](https://vuejs.org/v2/guide/components-props.html) and bind it the Generic component if used.
+
+### Skeleton
+```Vue
+<template>
+  <Generic :item="item">
+    <template #icon>
+      <!-- left area containing the icon -->
+    </template>
+    <template #content>
+      <!-- main area containing the title, subtitle, ... -->
+    </template>
+    <template #indicator>
+      <!-- top right area, empty by default -->
+    </template>
+  </Generic>
+</template>
+
+<script>
+import Generic from "./Generic.vue";
+
+export default {
+  name: "MyNewService",
+  props: {
+    item: Object,
+  },
+  components: {
+    Generic,
+  }
+};
+</script>
+```

+## Themes
 
 Themes are meant to be simple customization (written in [scss](https://sass-lang.com/documentation/syntax)).
-To addd a new theme, just add a file in the theme directory, and put all style in the `body #app.theme-<name>` scope. Then import it in the main style file.
