Thanks @pengtts, just a couple of suggestions.

Hi @pengtts @ArturoAmorQ
I'm reviewing the post and have the following comments / questions:
a) the file name needs to follow this format: yyyy-mm-dd.....
b) skolar is fully open source? Can a link to the GitHub repo be added somewhere? Is it the same as skore?
c) wonder if there should be a line at the top indicating this is a sponsor post, and not a scikit-learn project post, for clarification.

[ArturoAmorQ]

As per RL communication with @pengtts, I took the liberty to push some changes to this PR. I hope they help address your comments @reshamas :)

Thanks for the clarification in the authorship of this blog post and making the relationship between the probabl company and the scikit-learn project explicit. LGTM on my end, but I would like @reshamas or other non-probabl project members to give a +1 prior to merging/publishing.

Is this the right image to use? It sounds like it is some default thing?

[pengtts]

To be honest I have no idea, it seems like a default setting but let me know if you think some other image would be more appropriate? Thanks

[betatim]

I think you need to know what image you want in your post. From the name BSD_watermark.svg it sounds like this image is about the BSD license or some such, which is probably not a good feature image for this post.

What does the rendered blog post look like? Does an image appear or maybe an <img> tag that points to a non-existing image?

[betatim]

A few wording suggestions. Mostly about who is who/who is the voice of the post

[betatim]

"... With their support ... , we continue"

Maybe we can make it more explicit who is who here. At least I'm a bit lost if for example the "their" is the group of engineers employed by probabl, or probal or someone else? If it is probabl I think "With probabl's support and ..." would be clearer

[betatim]

Should we link to the homepages of these libraries?
