 ###### You can star and fork this repository on GitHub by navigating at the top of this repository.
 
 GitHub repository URLs will reference both the username associated with the owner of the repository, as well as the repository name. For example, acmbvp is the owner of the Hacktoberfest repository, so the GitHub URL for this project is:
 
 https://github.com/SanjayDevTech/Code-with-love

 When you’re on the main page of a repository, you’ll see a button to "Star" and “Fork” the repository on the upper right-hand side of the page, underneath your user icon.
 
 ### 2. Clone the Repository

 ### 3. Create a New Branch
 
 To create your branch, from your terminal window, change your directory so that you are working in the directory of the repository. Be sure to use the actual name of the repository (i.e. Code-with-love) to switch into that directory.
 
-#####    `cd Code-with-love`
+##### `cd Code-with-love`
 
 Now, we’ll create our new branch with the git branch command. Make sure you name it descriptively so that others working on the project understand what you are working on.
 
 ##### `git branch new-branch`
 
 Now that our new branch is created, we can switch to make sure that we are working on that branch by using the git checkout command:
 
-##### ` git checkout new-branch `
+##### `git checkout new-branch`
 
 Once you enter the git `checkout` command, you will receive the following output:
 
-######  `Output:`
-#####  `Switched to branch 'new-branch' `
+###### `Output:`
+
+##### `Switched to branch 'new-branch' `
 
+##### `code .`
+
+Once you enter this command, the whole code will automatically open in your code editor
 
 At this point, you can now modify existing files or add new files to the project on your own branch.
 
 #### Make Changes Locally
 
 Once you have modified existing files or added new files to the project, you can add them to your local repository, which you can do with the git add command. Let’s add the -A flag to add all changes that we have made:
 
-##### ` git add -A ` or ` git add . `
+##### `git add -A` or `git add .`
 
 Next, we’ll want to record the changes that we made to the repository with the git commit command.
 
-*The commit message is an important aspect of your code contribution; it helps the other contributors fully understand the change you have made, why you made it, and how significant it is. Additionally, commit messages provide a historical record of the changes for the project at large, helping future contributors along the way.*

 If you have a very short message, you can record that with the -m flag and the message in quotes:

-##### ` git commit -m "Updated Readme.md" `

+##### `git commit -m "Updated Readme.md"`

 We’ll first go over configuring a remote for the fork, then syncing the fork.
 
 ### 5. Configure a Remote for the Fork
 
 Next up, you’ll have to specify a new remote upstream repository for us to sync with the fork. This will be the original repository that you forked from. you’ll have to do this with the git remote add command.

If you want to add a remote pointer to the repository of a collaborator, you may want to provide that collaborator’s username or a shortened nickname for the shortname.

 Once you have configured a remote that references the upstream and original repository on GitHub, you are ready to sync your fork of the repository to keep it up-to-date.
 To sync your fork, from the directory of your local repository in a terminal window, you’ll have to use the // git fetch // command to fetch the branches along with their respective commits from the upstream repository. Since you used the shortname “upstream” to refer to the upstream repository, you’ll have to pass that to the command:
 
-##### ` git fetch upstream `
+##### `git fetch upstream`
 
 Switch to the local master branch of our repository:
 
-##### ` git checkout master `
+##### `git checkout master`
 
 Now merge any changes that were made in the original repository’s master branch, that you will access through your local upstream/master branch, with your local master branch:
 
-##### ` git merge upstream/master `
+##### `git merge upstream/master`
