I am personally not sure if this works 😅 but we could design an onboarding flow.

@flash520 `discovery` is not the sub-field of `apisix`.

@juzhiyuan Could you explain a bit more about the flow you are proposing? We already have the documentation right?

Yes, our markdown files contain that information. I want to know more about why users will miss this part, and how to help them onboard easily and smoothly :)

Also cc @navendu-pottekkat, @hf400159, and @avinal, we should consider a workflow on leading developers to onboard smoothly.

Our documentation already covers, https://github.com/apache/apisix/blob/master/docs/en/latest/discovery.md#configuration-for-eureka
Or we need to provide more detailed documentation (for each case).

@juzhiyuan From the error log prompted by the current system, it seems confusing. I have some suggestions. For example, the system will give a clear prompt for the supported configuration instructions in the prompt message. Just like the problem encountered this time, you can directly prompt: service found to belong to the top-level directive domain

Actually no. Documentation is one important entry to learn and use Apache APISIX for developers:
1. Follow the documentation (step 1, 2, 3) to know, learn and use something (e.g., Route).
2. For this issue, flash502 wants to configure Discovery but failed due to the wrong position in yaml. Then how to avoid these cases?
(not serious, more like a brainstorm)

I see. We can brainstorm and document how a user would use our documentation to achieve something.

Hi, @flash520, I'd like to know if there have any improvement we can do to avoid such cases 😄
Usually, we will search the Apache APISIX Website[1] or search codes directly. 😅 I just searched Apache APISIX Docs, and it says I should update the `discovery` field in the `conf` file, see https://github.com/apache/apisix/blob/master/conf/config-default.yaml#L304
Do you have any other suggestions?
