Hi @saeid93. Thanks for your PR.

I'm waiting for a SeldonIO or todo member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

@saeid93 This looks great. Can you make sure you can build the docs locally and also I imagine new pages need to be added to the indexes somewhere.

@saeid93 thank you very much for this, it's a great contribution! As you can see it seems the docs test is failing, this is because this new docs page is not linked from anywhere - could you add a link from the documentation? It could be on the reference index section, let me know if you have questions

[saeid93]

Thanks! Glad to help. @cliveseldon and @axsaucedo It should be fine now.

[axsaucedo]

@saeid93 it indeed looks good now - it seems we're experiencing some issues due to python-poetry/poetry#5826 (comment), we're investigating but should not be related to this so we should be ok to merge
