 ## Usage
 
-### DOM Manipulation
-
-JodaStyle allows for DOM manipulation using CSS attributes. Here are some examples:
-
-#### Wrap
-
-Wrap multiple consecutive elements in a new element using the `--joda-wrap` attribute:
-
-```html
-<div class="box"></div>
-<div class="box"></div>
-<div class="box"></div>
-```
-
-```css
-.box {
-  --joda-wrap: @row;
-}
-```
-
-The resulting DOM:
-
-```html
-<div class="row">
-    <div class="box"></div>
-    <div class="box"></div>
-    <div class="box"></div>
-</div>
-```
-
-#### Joda USE
-
-The `--joda-use` attribute allows the use of a template:
-
-```html
-<div class="box" style="--joda-use='box'; --layout-cols: 3"></div>
-```
-
-Is equivalent to:
-
-```html
-<div class="box" layout="use: box; cols: 3"></div>
-```
-
-The template element is copied over the host element, potentially changing the tag.
-
 ### Defining Templates
 
-Templates are defined using the `Joda.registerTemplate` method. Here's an example of defining a template:
+Templates are registered using `Joda.registerTemplate`:
 
-```typescript
+```ts
 import { Joda } from "@leuffen/jodastyle";
 
 Joda.registerTemplate("header1", `
@@ -104,9 +58,42 @@ Joda.registerTemplate("header1", `
 `);
 ```
 
+Optional parameters for `registerTemplate` include callbacks and layout defaults. Callbacks can be used to execute functions after the template is connected to the DOM or after all templates are connected and initialized. Layout defaults provide default values for layout-related CSS variables.
+
+Example using callbacks:
+
+```ts
+Joda.registerTemplate("footer1", `
+    <footer class="tjs-footer1">
+        ...
+    </footer>
+`, {}, {
+    onAfterConnectedCallback: (element) => {
+        console.log("Footer template connected:", element);
+    },
+    onAfterAllTemplatesConnectedCallback: (element) => {
+        console.log("All templates connected:", element);
+    }
+});
+```
+
+In the example above, we define a template named `header1` that can be used to create a header section with text and an image. The `:: mobile :lg: ` syntax is used to apply responsive classes. The `<slot>` elements are placeholders that will be filled with content when the template is used.
+
+#### Slot Attributes
+
+| Attribute      | Description                                      | Example                           |
+|----------------|--------------------------------------------------|-----------------------------------|
+| `data-select`  | Selector for the content to replace the slot with | `<slot data-select="img"></slot>` |
+| `data-replace` | Indicates that the slot content should be replaced | `<slot data-replace></slot>`      |
+| `data-copy`    | Indicates that the content should be copied instead of moved | `<slot data-copy></slot>`         |
+
+Slots are replaced in the order they are defined within the template. An element can only be selected once unless the `data-copy` attribute is set. If no `<slot>` element without a `data-select` attribute is found, elements that are not explicitly selected will be removed.
+
+To add classes or wrap a sub-element of a slot into its own template, use the `data-child-class` attribute or the `--joda-wrap` command respectively.
+

-### Processing HTML Input with JodaSplit
+It's important to include the `#` symbol when referencing a template to avoid unexpected behavior.
+
+In the example above, the `layout="use: #header1"` attribute tells JodaStyle to apply the `header1` template to the `div`. The `img` element will replace the first slot with `data-select="img"`, and the rest of the content will fill the default slot.
 
-JodaSplit reorganizes flat HTML into a structured tree. For detailed information about the structure of the output, refer to the [jodasplit-output.html](/jodasplit/jodasplit-output.html) file.
+### DOM Manipulation Commands
 
-### Responsive Design
+JodaStyle provides several commands for manipulating the DOM using CSS attributes:
 
-Jodaresponsive replaces media queries in CSS files, drastically reducing file sizes. The syntax in the `class` attribute is as follows:
+#### Wrap Command
+
+The `--joda-wrap` command wraps one or more consecutive elements in a new element:
+
+```css
+.box {
+  --joda-wrap: @row;
+}
+```
+
+This will wrap elements with the class `.box` in a new element with the class `row`.
+
+#### Use Command
+
+The `--joda-use` command allows the use of a template:
 
 ```html
-<div class="col :: col-6 :md: col-4 :lg: col-2"></div>
+<div class="box" style="--joda-use='box'; --layout-cols: 3"></div>
 ```
 
-Is equivalent to:
+This is equivalent to:
 
 ```html
-<div class="col col-6 col-md-4 col-lg-2"></div>
+<div class="box" layout="use: box; cols: 3"></div>
 ```
 
+The `use` command copies the template element over the host element, potentially changing the tag.
+
+### Processing HTML Input with JodaSplit
+
+JodaSplit reorganizes flat HTML into a structured tree:
+
+```html
+<joda-split>
+    <nav layout="use: #navbar-switch1" class="floating">
+        ...
+    </nav>
+    <h1 layout="use: #header1" data-section-class="decreased-height">Kontakt</h1>
+    ...
+</joda-split>
+```
+
+JodaSplit transforms the input into a tree structure where `<h1>` and `<h2>` elements become `<section>` elements, while `<h3>` to `<h6>` become nested elements.
+
+You can use `<hr>` elements to insert sub-elements. Additional attributes and classes set on an element with the `layout=""` attribute will be preserved.
+
+For a detailed example of how JodaSplit processes input, see the [jodasplit-output.html](/jodasplit/jodasplit-output.html) file.
+
+### Responsive Design (Jodaresponsive)
+
+JodaStyle includes a processor for responsive design, which applies classes based on the viewport size and custom responsive classes.
+
+For more information on how to use responsive design with JodaStyle, refer to the [Jodaresponsive](/processor/jodaresponsive.ts) processor.
