+   where such license applies only to those patent claims licensable
+   by such Contributor that are necessarily infringed by their
+   Contribution(s) alone or by combination of their Contribution(s)
+   with the Work to which such Contribution(s) was submitted. If You
+   institute patent litigation against any entity (including a
+   cross-claim or counterclaim in a lawsuit) alleging that the Work
+   or a Contribution incorporated within the Work constitutes direct
+   or contributory patent infringement, then any patent licenses
+   granted to You under this License for that Work shall terminate
+   as of the date such litigation is filed.
+
+4. Redistribution. You may reproduce and distribute copies of the
+   Work or Derivative Works thereof in any medium, with or without
+   modifications, and in Source or Object form, provided that You
+   meet the following conditions:
+
+   (a) You must give any other recipients of the Work or

+   attribution notices from the Source form of the Work,
+   excluding those notices that do not pertain to any part of
+   the Derivative Works; and
+
+   (d) If the Work includes a "NOTICE" text file as part of its
+   distribution, then any Derivative Works that You distribute must

+   within such NOTICE file, excluding those notices that do not
+   pertain to any part of the Derivative Works, in at least one
+   of the following places: within a NOTICE text file distributed
+   as part of the Derivative Works; within the Source form or
+   documentation, if provided along with the Derivative Works; or,
+   within a display generated by the Derivative Works, if and
+   wherever such third-party notices normally appear. The contents
+   of the NOTICE file are for informational purposes only and
+   do not modify the License. You may add Your own attribution
+   notices within Derivative Works that You distribute, alongside
+   or as an addendum to the NOTICE text from the Work, provided
+   that such additional attribution notices cannot be construed
+   as modifying the License.
+
+   You may add Your own copyright statement to Your modifications and
+   may provide additional or different license terms and conditions
+   for use, reproduction, or distribution of Your modifications, or
+   for any such Derivative Works as a whole, provided Your use,
+   reproduction, and distribution of the Work otherwise complies with
+   the conditions stated in this License.
+
+5. Submission of Contributions. Unless You explicitly state otherwise,
+   any Contribution intentionally submitted for inclusion in the Work
+   by You to the Licensor shall be under the terms and conditions of

+   origin of the Work and reproducing the content of the NOTICE file.
+
+7. Disclaimer of Warranty. Unless required by applicable law or
+   agreed to in writing, Licensor provides the Work (and each
+   Contributor provides its Contributions) on an "AS IS" BASIS,
+   WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+   implied, including, without limitation, any warranties or conditions

+   PARTICULAR PURPOSE. You are solely responsible for determining the
+   appropriateness of using or redistributing the Work and assume any
+   risks associated with Your exercise of permissions under this License.
+
+8. Limitation of Liability. In no event and under no legal theory,
+   whether in tort (including negligence), contract, or otherwise,
+   unless required by applicable law (such as deliberate and grossly
+   negligent acts) or agreed to in writing, shall any Contributor be
+   liable to You for damages, including any direct, indirect, special,
+   incidental, or consequential damages of any character arising as a
+   result of this License or out of the use or inability to use the
+   Work (including but not limited to damages for loss of goodwill,
+   work stoppage, computer failure or malfunction, or any and all
+   other commercial damages or losses), even if such Contributor
+   has been advised of the possibility of such damages.

+9. Accepting Warranty or Additional Liability. While redistributing
+   the Work or Derivative Works thereof, You may choose to offer,
+   and charge a fee for, acceptance of support, warranty, indemnity,
+   or other liability obligations and/or rights consistent with this
+   License. However, in accepting such obligations, You may act only
+   on Your own behalf and on Your sole responsibility, not on behalf
+   of any other Contributor, and only if You agree to indemnify,
+   defend, and hold each Contributor harmless for any liability
+   incurred by, or claims asserted against, such Contributor by reason
+   of your accepting any such warranty or additional liability.

+  <h1>WeMod Patcher</h1>
+</div>
+
+---
+
+<h4>WeMod patcher allows you to get some WeMod features absolutely free. This script patches WeMod, thereby removing the daily usage limit (2h), etc.</h4>
+
+## 👾 No malware? Is it safe for me?
+
+---
+
+Yes, this is safe. This script is open-source, and you can check the code yourself. I have no intention of harming you or your computer. The script does absolutely nothing with your computer and does not require Internet access. It only affects WeMod files.
+
+## 💻 Does this script only work with older versions of WeMod like other unlockers?
+
+---
+
+With this patch you will be able to use the latest version together with Pro. 
+
+##  👀 What features will be available?
+
+---
+
+✅ Unlimited usage time <br/>
+✅ No ads <br/>
+✅ AI Game guides <br/>
+✅ Saving mods <br/>
+❌ Connect phone <br/>
+❌ Hotkeys (hotkey functionality breaks after patch for unknown reason)
+
+## ❓ How to use?
+
+---
+1. **Clone the Repository (or just download source code)**
+    ``` bash
+    git clone https://github.com/k1tbyte/Wemod-patcher.git
+    cd Wemod-patcher
+    ```
+2. **Run the script**
+    ``` bash
+    bun install/npm install/yarn install/whatever you use
+    npm ./unlocker.js
+    ```
+3. **Follow the instructions**
