 ## Highlights
 
 - Installing using official cloud images (Cloud Image) allows bypassing the [memory requirements](https://access.redhat.com/articles/rhel-limits#minimum-required-memory-3) of traditional network installations, resulting in faster installation speed.
-- Using official cloud images for installation ensures fast installation speed and can also avoid issues with netboot installation on machines with limited memory.
 - Compatible with 512M + 5G small servers and supports installing Alpine on 256M small servers.
 - Compatible with all network conditions, including dynamic/static IPv4/IPv6 and pure IPv4/IPv6.
 - Supports installing Windows using the official ISO.
