+## Contribution
+
+If you want to add any enhancement feature or have found any bug and want to work on it, please open a new issue regarding that and put a message "I would like to work on it." And make sure every pull request should reference to an issue.
+
+#### Points on how to make pull request
+* You need to fork this repository to your account.  
+
+* Clone it using ``` git clone https://github.com/FOSSEE/nghdl.git ```
+
+* Always create a new branch before making any changes. You can create new branch using ```git branch <branch-name> ```
+
+* Checkout into your new branch using ```git checkout <branch-name>```
+
+* Make changes to code and once you are done use ```git add <path to file changed or added>```. Now commit  changes with proper message using ```git commit -m "Your message"```.
+
+* After commiting your changes push your changes to your forked repository using ```git push origin <branch-name>```
+Finally create a pull request from github.
+There should be only one commit per pull request.
+
+
+* Please follow below guidelines for your commit message :
+  * Commit message should be like : Fixes issue #[issue_number] - one line message of work you did.
