 ## Usage
 To open a sign editor gui for a player, do the following:
 ```java
-SignGUI gui = SignGUI.builder()
-    // set lines
-    .setLines("§6Line 1", null, "§6Line 3")
-
-    // set specific line, starting index is 0
-    .setLine(3, "Line 4")
-
-    // set the sign type
-    .setType(Material.DARK_OAK_SIGN)
-
-    // set the sign color
-    .setColor(DyeColor.YELLOW)
-
-    // set the handler/listener (called when the player finishes editing)
-    .setHandler((p, result) -> {
-        // get a speficic line, starting index is 0
-        String line0 = result.getLine(0);
-
-        // get a specific line without color codes
-        String line1 = result.getLineWithoutColor(1);
-
-        // get all lines
-        String[] lines = result.getLines();
-
-        // get all lines without color codes
-        String[] linesWithoutColor = result.getLinesWithoutColor();
-
-        if (line1.isEmpty()) {
-            // The user has not entered anything on line 2, so we open the sign again
-            return List.of(SignGUIAction.displayNewLines("§6Line 1", null, "§6Line 3", "Line 4"));
-        }
-
-        if (line1.equals("inv")) {
-            // close the sign and open an inventory

-                SignGUIAction.run(() -> player.sendMessage("Inventory opened!"))
-            );

-        return Collections.emptyList();
-    })

 You don't have to call all methods. Only `setHandler` is mandatory.
 
 By default, the handler is called by an asynchronous thread. You can change that behaviour by calling the method `callHandlerSynchronously` of the builder.
 An explanation for the different methods can be found on the [Javadoc](https://javadoc.io/doc/de.rapha149.signgui/signgui).
 
+Also: as you can see the code catches the `SignGUIVersionException` which could be thrown by `SignGUI.builder()` if the api does not support the Minecraft version of the server.
+If you're interested in why this exception exists, check the [release notes](https://github.com/Rapha149/SignGUI/releases/tag/v2.5.0).

 ## Limitations
 
 ### Players can edit pre-written lines
