 # README
 
-This README would normally document whatever steps are necessary to get the
-application up and running.
+## Planning
 
-Things you may want to cover:
+### Question for the Product Manager
+ - We will allow user to use @mentioning only in the beginning of text?
+ - What do you think about create an extensive architecture to support new features, creating a relation of posts and users through Mention entity?
 
-* Ruby version
+### Implementation
+  1. Improve Post entity scopes, moving `post`, `repost`, `quoted_post` and `reply` to `kind enum column`, becase of the static characteristic of posts a precomputed status will be perfect to simplify queries.
+  2. Rename `Post#quoted_post` to `Post#reference`
+  3. Add a reply route to post, example `POST /posts/1/replys`, when creating a reply save post with kind
+  4. When quering a `reply`, the frontend will concat orignal post owner username with post content
