@peoray
Can You please add step by step screenshot also.
Now onwards with each new provider docs, we are starting to add screenshot.

[peoray]

@jainpawan21 how do we intend to add images?
where will images be stored?

[scopsy]

@peoray images are stored today at the /static folder for images. And served by docasaurus. Located in this folder: https://github.com/novuhq/novu/tree/next/docs/static/img

They can than be referenced with the /static path from the .md files

[peoray]

Thank you @scopsy
Do I create folders for each provider or just dump the images there?
Also, the step by step screenshot, does it include also getting the api key from the provider, or just adding it to Novu integration (usually the last part of the docs)

Pardon my many questions, since there's no similar example to follow, I'd like to be clear on what to do. I don't mind also working on current docs and adding the images where necessary once I understand what to do

[scopsy]

@peoray really up to you :) You can create a folder for the provider, I agree that it will be easier to maintain on the long run.

@peoray Do you still have plans to update this?

[peoray]

Yes @unicodeveloper

[peoray]

Although, I can't show images for adding the Account SID and Auth token from Plivo because it's not available in my region

[unicodeveloper]

No problem. Can you update it with the ones available?

[peoray]

Sure, I'll update the PR today. Will ping you

[peoray]

@unicodeveloper please take a look

[p-fernandez]

This looks good to me.
Just maybe even if not harmful next time split the PR in 2, one for each provider.
Thank you for your contribution.

What do you mean @p-fernandez

What do you mean @p-fernandez

To have splitted in 2 different PRs the Plivo and the Africa's Talking documentation additions. 🙂

[peoray]

@p-fernandez This is one PR, I just pulled the changes from AT cause it had the images folder setup since it was the first provider that I did with images and I didn't want to cause a conflict
