+## GitHub Integration
+
+To push the auto-generated SDK to GitHub, we provide `git_push.sh` to streamline the process. For example:
+
+ 1) Create a new repository in GitHub (Ref: https://help.github.com/articles/creating-a-new-repository/)
+ 
+ 2) Generate the SDK
+```
+ java -jar modules/swagger-codegen-cli/target/swagger-codegen-cli.jar generate \
+ -i modules/swagger-codegen/src/test/resources/2_0/petstore.json -l perl \
+ --git-user-id "wing328" \
+ --git-repo-id "petstore-perl" \
+ --release-note "Github integration demo" \
+ -o /var/tmp/perl/petstore
+```
+ 3) Push the SDK to GitHub
+```
+cd /var/tmp/perl/petstore
+/bin/sh ./git_push.sh
+```
