+**Author:** [Aimee Ukasick](https://www.linkedin.com/in/aimee-ukasick/) and SIG Docs
+
+In September, SIG Docs conducted its first survey about the [Kubernetes
+documentation](https://kubernetes.io/docs/). We'd like to thank the CNCF's Kim
+McMahon for helping us create the survey and access the results.
+
+# Key takeaways
+
+Respondents would like more example code, more detailed content, and more
+diagrams in the Concepts, Tasks, and Reference sections.
+
+74% of respondents would like the Tutorials section to contain advanced content.
+
+69.70% said the Kubernetes documentation is the first place they look for
+information about Kubernetes.
+
+# Survey methodology and respondents
+
+We conducted the survey in English. The survey was only available for 4 days due
+to time constraints. We announced the survey on Kubernetes mailing lists, in
+Kubernetes Slack channels, on Twitter, and in Kube Weekly. There were 23
+questions, and respondents took an average of 4 minutes to complete the survey.
+
+## Quick facts about respondents:
+
+- 48.48% are experienced Kubernetes users, 26.26% expert, and 25.25% beginner
+- 57.58% use Kubernetes in both administrator and developer roles
+- 64.65% have been using the Kubernetes documentation for more than 12 months
+- 95.96% read the documentation in English
+
+# Question and response highlights
+
+## Why people access the Kubernetes documentation
+
+The majority of respondents stated that they access the documentation for the Concepts.

+    alt="Why respondents access the Kubernetes documentation"
+>}}
+
+This deviates only slightly from what we see in Google Analytics: of the top 10
+most viewed pages this year, #1 is the kubectl cheatsheet in the Reference section,
+followed overwhelmingly by pages in the Concepts section.
+
+## Satisfaction with the documentation
+
+We asked respondents to record their level of satisfaction with the detail in
+the Concepts, Tasks, Reference, and Tutorials sections:
+
+- Concepts: 47.96% Moderately Satisfied
+- Tasks: 50.54% Moderately Satisfied
+- Reference: 40.86% Very Satisfied
+- Tutorial: 47.25% Moderately Satisfied
+
+## How SIG Docs can improve each documentation section
+
+We asked how we could improve each section, providing respondents with
+selectable answers as well as a text field. The clear majority would like more
+example code, more detailed content, more diagrams, and advanced tutorials:
+
+```text
+- Personally, would like to see more analogies to help further understanding.
+- Would be great if corresponding sections of code were explained too
+- Expand on the concepts to bring them together - they're a bucket of separate eels moving in different directions right now
+- More diagrams, and more example code
+ ```
+
+Respondents used the "Other" text box to record areas causing frustration:
+
+```text
+- Keep concepts up to date and accurate
+- Keep task topics up to date and accurate. Human testing.
+- Overhaul the examples. Many times the output of commands shown is not actual.
+- I've never understood how to navigate or interpret the reference section
+- Keep the tutorials up to date, or remove them
+```
+
+## How SIG Docs can improve the documentation overall
+
+We asked respondents how we can improve the Kubernetes documentation
+overall. Some took the opportunity to tell us we are doing a good job:
+
+```text
+- For me, it is the best documented open source project.
+- Keep going!
+- I find the documentation to be excellent.
+- You [are] doing a great job. For real.
+```
+
+Other respondents provided feedback on the content:
+
+```text
+-  ...But since we're talking about docs, more is always better. More
+advanced configuration examples would be, to me, the way to go. Like a Use Case page for each
+configuration topic with beginner to advanced example scenarios. Something like that would be
+awesome....
+- More in-depth examples and use cases would be great. I often feel that the Kubernetes
+documentation scratches the surface of a topic, which might be great for new users, but it leaves
+more experienced users without much "official" guidance on how to implement certain things.
+- More production like examples in the resource sections (notably secrets) or links to production like
+examples
+- It would be great to see a very clear "Quick Start" A->Z up and running like many other tech
+projects. There are a handful of almost-quick-starts, but no single guidance. The result is
+information overkill.
+```
+
+A few respondents provided technical suggestions:
+
+```text
+- Make table columns sortable and filterable using a ReactJS or Angular component.
+- For most, I think creating documentation with Hugo - a system for static site generation - is not
+appropriate. There are better systems for documenting large software project. Specifically, I would
+like to see k8s switch to Sphinx for documentation. It has an excellent built-in search, it is easy to
+learn if you know markdown, it is widely adopted by other projects (e.g. every software project in
+readthedocs.io, linux kernel, docs.python.org etc).
+```
+
+Overall, respondents provided constructive criticism focusing on the need for
+advanced use cases as well as more in-depth examples, guides, and walkthroughs.
