Thank you @git-yww

Can you please add an item under https://github.com/ahrtr/etcd-defrag#note something like below?

Please do not get learner members' endpoints included in `--endpoints`,  refer to discussion in https://github.com/ahrtr/etcd-defrag/issues/26.

[git-yww]

Absolutely. That's a good point.

[git-yww]

Due to that one etcd cluster only supports one learner member, so the item to add will be like:
Please do not get learner member endpoint included in --endpoints, refer to discussion in https://github.com/ahrtr/etcd-defrag/issues/26.

The default maxLearner is 1, but actually it's configurable via the flag --experimental-max-learners, so let's use the plural noun.

Thanks again! Nice work!
