@dogukanteber This is great - exactly the sorts of things we were discussing in the PR. What do you think about adding the link to the examples.rst in the docs folder? Can I trouble you to connect the dots. After that, we'll merge right in!.

[dogukanteber]

Oh, I completely forgot about that part @chayim. I linked the file to example.rst. Even though I can see the generated file in my browser, I have no idea why I am failing in unit tests. Do you have any idea?

[chayim]

@dogukanteber This is perfect! Unit tests are failing due to an upstream docker issue that I need to fix. This is solidly approved - I'll merge once I have that docker fixed. So excited!!!!

[chayim]

Approved - needs the same redismod upstream docker fix as other PRs. This is on me.
