-### LibCare for Proxmox VE 8
+#### LibCare for Proxmox VE 8
 
 Shared libraries like **OpenSSL** and **glibc** are fundamental to the operation of many applications and services. Vulnerabilities in these libraries can lead to serious security breaches, such as unauthorized data access or remote code execution. Traditionally, updating these libraries requires restarting the services or applications that use them, which can cause downtime.
 
 **LibCare** provides a solution by enabling live patching of these critical shared libraries without the need to restart dependent services or reboot the servers. This ensures that security updates are applied promptly, keeping your system secure while maintaining service availability.
