+# Install
+
+The generator is designed to work on Windows, as it uses the `makecab` utility. Before usage, be sure to install required dependencies:
+
+* With Virtualenv
+
+```
+git clone https://github.com/klezVirus/CVE-2021-40444
+cd CVE-2021-40444
+pip install virtualenv
+python -m virtualenv venv
+venv\Scripts\activate.bat 
+pip install -r requirements
+```
+
+* Without Virtualenv
+
+```
+git clone https://github.com/klezVirus/CVE-2021-40444
+cd CVE-2021-40444
+pip install -r requirements
+```
