 # Kubernetes Branding Guidelines
 
-These guidelines provide you with guidance for using the Kubernetes logo. You
-can use the logo on your website or in print without pre-approval, provided you
-follow these basic guidelines.
-
-You may display, modify, or use the Kubernetes logo only in connection with
-compliant implementations of Kubernetes and related uses in the following ways.
-A compliant implementation is an implementation of the unmodified Cloud Native
-Compute Foundation (CNCF)
-version of Kubernetes found at https://github.com/kubernetes/kubernetes and
-compatible branches thereof, together with published specifications, APIs and
-operational patterns.  Acceptable related uses include display, modification,
-or use of the Kubernetes logo in connection with your compliant implementation,
-your integration with a compliant implementation, your support for a compliant
-implementation, your Kubernetes-compatible product, or in collateral,
-presentations, and marketing materials relating to compliant implementations of
-Kubernetes.
-
-All other uses of this logo are covered by the Linux Foundation trademark
-guidelines found [here](https://linuxfoundation.org/trademark-usage).
+These guidelines provide you with guidance for using the Kubernetes logo.
+All artwork is made available under the Linux Foundation trademark usage
+[guidelines](https://www.linuxfoundation.org/trademark-usage/). This text from
+those guidelines, and the correct and incorrect usage examples, are particularly
+helpful:
+>Certain marks of The Linux Foundation have been created to enable you to
+>communicate compatibility or interoperability of software or products. In
+>addition to the requirement that any use of a mark to make an assertion of
+>compatibility must, of course, be accurate, the use of these marks must
+>avoid confusion regarding The Linux Foundation’s association with the
+>product. The use of the mark cannot imply that The Linux Foundation or
+>its projects are sponsoring or endorsing the product.
+
+Additionally, permission is granted to modify the Kubernetes mark for non-commercial uses such as t-shirts and stickers.
