-The SEV-SNP support requires firmware version >= 1.50:1. The latest SEV-SNP firmware is available on developer.amd.com/sev and on linux-firmware project.
-Follow the below step to upgrade to latest firmware
+The SEV-SNP support requires firmware version >= 1.50:1. The latest SEV-SNP firmware is available on https://developer.amd.com/sev and eventually via linux-firmware project.

+The below steps document the firmware upgrade process for the latest SEV-SNP firmware available on https://developer.amd.com/sev at the time this was written. A similar procedure can be used for newer firmwares as well:
```
-# wget https://developer.amd.com/wp-content/resources/amd_sev_fam19h_model0xh_1.33.01.zip
-# unzip amd_sev_fam19h_model0xh_1.33.01.zip
+# wget https://developer.amd.com/wp-content/resources/amd_sev_fam19h_model0xh_1.33.03.zip
+# unzip amd_sev_fam19h_model0xh_1.33.03.zip
# sudo mkdir -p /lib/firmware/amd
-# sudo cp amd_sev_fam19h_model0xh_1.33.01.sbin /lib/firmware/amd/amd_sev_fam19h_model0xh.sbin
+# sudo cp amd_sev_fam19h_model0xh_1.33.03.sbin /lib/firmware/amd/amd_sev_fam19h_model0xh.sbin
```
Then either reboot the host, or reload the ccp driver to complete the firmware upgrade process:
