 ### Allowing and blocking
 
-Don't use "whitelist" or "blacklist" when referring to allowing or blocking content or traffic.
+When referring to _allowing_ or _blocking_ content or traffic, use a form of _allow_ or _block_:
 
-- When used as a noun, use "allowlist" or "blocklist".
-- When used as a verb, use "allow" or "block"
+- (noun) _allowlist_ or _blocklist_
+- (verb) _allow_ or _block_
 
 Example: _To **allow** outgoing traffic, add the IP to the **allowlist**._
 
-### Leader and follower
+Avoid _whitelist_ or _blacklist_.
 
-Don't use "master" or "slave" to describe relationships between nodes or processes.
+### Primary and secondary
 
-- Use "leader", "main" or "primary," instead of "master."
-- Use "follower" or "secondary," instead of "slave."
+To describe relationships between nodes or processes, there are several options:
 
-### Exceptions
+- Use _primary_, _main_, or _parent_, instead of _master_.
+- Use _secondary_, _replica_, or _child_, instead of _slave_.
 
-When referring to a configuration or settings used by third-party libraries och technologies outside the Grafana project, prefer the original name to avoid confusion.
-
-For example, use "master" when referring to the default Git branch.
+Avoid _master_ or _slave_.
 
 ## Grafana-specific style
