Stage 2 settlement clarification

Guys I just got my stage 2 visa stamped and in the email they sent me they state the below :

# Routes to settlement in the UK
*Where you have been granted 33 months of entry clearance under Appendix FM, the endorsement on your vignette will tell you the basis on which you have been granted permission under the Rules. That will also help you to identify when you are likely to be able to apply for settlement (assuming that you continue to meet the relevant requirements):

# Standard endorsement

Where the endorsement on your vignette includes the phrase ‘standard’ it means that you are currently on a 5-year route to settlement.

If you continue to meet the requirements and make the appropriate applications for further permission to stay, you are likely to be eligible to apply for settlement in 5 years.

what does it mean by " (assuming that you continue to meet the relevant requirements" what requirements do I need to keep meeting for 5 years?
