+cocoapods-binary is not maintained now, because the owner of cocoapods-binary is currently busy.
+Although, this plugin brings us a bunch of advantages in working iOS app development.
 So I created this forked repo inorder to gather PRs to fix issues and merge into the original repository in the future.
 
+## Installation
+
+```
+gem 'cocoapods-binary', git: "https://github.com/muukii/cocoapods-binary.git", branch: "master"
+```
+
+## Contribution
+
+Please submit a PR to my forked repo from `https://github.com/muukii/cocoapods-binary/pulls`.
+I'll merge it. 
+**But I can't review well because I don't have much experience with Ruby. So I really need developers who can handle ruby code.**
