@GeoDaoyu should follow the format of api docs:

• navigation links
• ts support
• examples
• troubleshooting section if needed

This looks like you copy/paste the code from README.md file

@GeoDaoyu still missing some parts I don't see how someone can use this guide to create a custom middleware and doesn't seems that fits into the api docs

Where should it be placed if it doesn't seems that fits into the api docs?

@GeoDaoyu should be under guides and the goal should be a guide that takes you through all the steps needed to create a custom middleware.

Note

A custom middleware guide could be the most complex guide in Zustand docs

Ok. I'll move it under guides later.

I'll do my best to finish it through it might be the most complexed.

@dbritto-dev I rewrite it under the guides.
