+# Java Pastebin License-Key Checker
+
+A Java library for license key validation. The license key is retrieved from a Raw Pastebin URL and compared against the license key provided by the user.
+## Usage/Examples
+
+The library is provided as a JAR file. You can include it in your project and use the `LicenseChecker` class to check the license key.
+
+**Constructor**: 
+```java
+public LicenseChecker(String pastebinRawUrl, String licenseKey)
+```
+
+Creates a new LicenseChecker that searches for the license key in the specified Raw Pastebin URL and compares it with the licenseKey provided by the user.
+
+- `pastebinRawUrl` - The Raw Pastebin URL that contains the license key.
+- `licenseKey` - The license key provided by the user.
+
+**Method**:
+```java
+public boolean checkLicenseKey() throws IOException
+```
+Checks whether the license key provided by the user is contained in the content of the specified Raw Pastebin URL.
+
+## Example
+
+Here's an example that shows how you can use the library in your Java code:
+
+```java
+import java.io.IOException;
+
+public class MyProgram {
+    public static void main(String[] args) {
+        LicenseChecker checker = new LicenseChecker("https://pastebin.com/raw/PASTE_ID", "LICENSE_KEY");
+        try {
+            if (checker.checkLicenseKey()) {
+                System.out.println("License key is valid.");
+            } else {
+                System.out.println("Invalid license key.");
+            }
+        } catch (IOException e) {
+            System.out.println("Error checking license key: " + e.getMessage());
+        }
+    }
+}
+```
+In this example, a `LicenseChecker` is instantiated with the Raw Pastebin URL and license key, and the `checkLicenseKey` method is called. If the license key is valid, a message is printed saying that the license key is valid. Otherwise, a message is printed saying that the license key is invalid.
