Description

The medik8s.io remediation page currently lists the following remediators:

1. Self Node Remediation (SNR)
2. Metal³ (WIP)
3. Machine Deletion Remediation (MDR)
4. Fence Agents Remediation (FAR)

Storage Based Remediation (SBR) is missing from this page and from the site navigation. SBR is an active medik8s remediator and should be documented alongside the other remediators.
