 **How to build and use the customized TwitterKit pod**
-1. Open the DemoApp project and there is a sub project TwitterKit.
-2. Select schema: TwitterKit ==> Generic iOS Device, `Clean`, `Run` and you get a TwitterKit.framework with architecture: armv7, arm64
-3. Select schema: TwitterKit ==> any iOS Simulator, `Clean`, `Run` and you get a  TwitterKit.framework with architecture: x86_64
-4. Use `lipo` to merge above two framework into one, which include architecture: armv7, arm64, x84_64
-    ```
-    lipo -create -output TwitterKit <Framework built in step 2>/TwitterKit <Framework built in step 3>/TwitterKit
-    ```
-    Check the new TwitterKit is correct.
-    ```
-    lipo -archs TwitterKit
-    ```
-    Will return `x86_64 armv7 arm64 `
-
-5. Replace the `TwitterKit` in framework created in step 2 with the merged one.
-6. Create a folder `iOS`, move the framework folder in step 5 inside, zip the `iOS` folder and you get TwitterKit pod zip file.
-7. Upload the zip file somewhere and get a [URL](https://swarm-dev.s3.amazonaws.com/pods/twitterkit/ios/5.0.0/TwitterKit.zip) points to it.
-8. Change your [podspec file](https://raw.githubusercontent.com/touren/twitter-kit-ios/Swift5/TwitterKit/TwitterKit.podspec) as:  s.source = { :http => "<URL created in step 7>" }
-9. Change your Podfile as: `pod "TwitterKit"` ==> `pod "TwitterKit", :podspec => "<URL point to the podspec created in step 8>"`
+1. Build TwitterKit.zip. In the root folder of the project, run
+```
+./build.sh
+```
+2. Upload the TwitterKit.zip file somewhere and get a [URL](https://swarm-dev.s3.amazonaws.com/pods/twitterkit/ios/5.0.0/TwitterKit.zip) points to it.
+3. Change your [podspec file](https://raw.githubusercontent.com/touren/twitter-kit-ios/Swift5/TwitterKit/TwitterKit.podspec) as:  s.source = { :http => "<URL created in step 2>" }

+**How to build and push to CocoaPods TwitterKit5**
+1. Build TwitterKit.zip. In the root folder of the project, run
+```

+```
+2. Release a new version in [GitHub](https://github.com/touren/twitter-kit-ios/releases), say 5.0.2, upload the TwitterKit.zip just built.
