+# Version Check Mod for 7 Days to Die
+
+This mod for 7 Days to Die checks for version mismatches between the game and the mod, and provides optional features to enhance the game experience.
+
+## Features
+
+- Version mismatch detection: Compares the game version with the mod version and displays a warning if they don't match.
+- Configurable error messages: Customize the title and description of the version mismatch warning.
+- Option to disable the news screen: Skip the news screen on game startup.
+
+## Installation
+
+1. Download the latest release of the mod from the [Releases](https://github.com/yourusername/versioncheckmod/releases) page.
+2. Extract the contents of the zip file into your 7 Days to Die Mods folder.
+3. Ensure that the `versioncheck.xml` file is present in the mod folder.
+
+## Configuration
+
+The mod is configured using the `versioncheck.xml` file. You can customize the following settings:
+
+- `ModVersion`: Set this to the version of the game that the mod is designed for.
+- `DisableNewsScreen`: Set to `true` to skip the news screen on game startup.
+- `ErrorMessage`:
+    - `Title`: Customize the title of the version mismatch warning.
+    - `Description`: Customize the description of the version mismatch warning.
+
+Example configuration:
+
+```xml
+<?xml version="1.0" encoding="UTF-8"?>
+<xml>
+    <!-- Configuration for the Version Check -->
+    <Settings>
+        <!-- Set this to the version of the game you're modding -->
+        <!-- This should match the version in the game's build version which is visible in the main menu (top right) -->
+        <!-- Example: b316 would be <ModVersion>1.0.316</ModVersion> -->
+        <ModVersion>1.0.316</ModVersion>
+
+        <!-- Set to true to disable the news screen on game start -->
+        <!-- Set to false to keep the default behavior -->
+        <DisableNewsScreen>false</DisableNewsScreen>
+
+        <!-- Customize the version mismatch error message -->
+        <ErrorMessage>
+            <!-- Title of the error message box -->
+            <Title>Version Mismatch Detected</Title>
+            <!-- Description of the error. Use {0} for game version and {1} for mod version -->
+            <Description>The game version ({0}) does not match the mod version ({1}). This may cause issues.</Description>
+        </ErrorMessage>
+    </Settings>
+</xml>
+```
+
+## Usage
+
+1. Start 7 Days to Die with the mod installed.
+2. If there's a version mismatch between the game and the mod, you'll see a warning message when entering the main menu.
+3. The news screen will be skipped if you've set `DisableNewsScreen` to `true` in the configuration.
+
+## Compatibility
+
+This mod is designed to work with 7 Days to Die version 1.0. It may work with other versions, but compatibility is not guaranteed.
+You're free to modify this to work with your mod. It should require little if any changes between game versions.
