+## Inclusive language
+
+This section provides guidelines on how to avoid using charged language in documentation.
+
+### Allowing and blocking
+
+Don't use "whitelist" or "blacklist" when referring to allowing or blocking content or traffic.
+
+* When used as a noun, use "allowlist" or "blocklist".
+* When used as a verb, use "allow" or "block"
+
+Example: _To **allow** outgoing traffic, add the IP to the **allowlist**._
+
+### Leader and follower
+
+Don't use "master" or "slave" to describe relationships between nodes or processes.
+
+* Use "leader", "main" or "primary," instead of "master."
+* Use "follower" or "secondary," instead of "slave."
+
+### Exceptions
+
+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.
