Bitbucket is a hosting service which is used to store source code of any application and code reviews. We can store source code of the application in bitbucket with the help of repository. The repository is used to store source code and any further modification in the application source code can be updated in the repository by committing that code to the particular repository.

If more than one developer is working on a single application, so it provides the feature of multiple commits with a push of source code to the server and source code pull feature is also available. Pull is to take the updated code from the repository and push to update the source code in the repository.

We need to create a repository for further working, so In this tutorial, I am providing the steps to create repository in bitbucket:

Step 1: Go to link https://bitbucket.org/ and login with your bitbucket credentials. If not registered please register first and then login.

Step 2: After login click + icon on left side menu bar and select repository among the list.

Step 3: Create a new repository page will come write down the name of your repository and click create repository button.

Step 4:  After creation of repository it will redirect user to the new created repository with the mentioned name. As here name of repository is DemoApp so that is visible at the top of the screen on left hand side.

When you will see the above screen in bitbucket repository after that click on create a .gitignore file which redirect you to the screen given below:-

Now the below mentioned code you have to include in the space provided in above screenshot.
