Question/suggestion: Membership Releted Operation instruction in Readme.md file would be great

[rezwan]

The readme.md instruction is very clear. It works perfectly with me. No issue.
It would be great if I find something there--- related to
-member,organization when creating new channel.
-create/join channel for a peer
-more about policy
-Does cli container works with this fabric ca

• is there any CLI command for creating new member with role.
  Actually hard to find proper doc :)
