Changing the Remote Origin URL

To change the URL of the remote origin, follow these steps:

Open a terminal and navigate to your local Git repository.
Use the git remote set-url command to update the remote origin URL:
```
git remote set-url origin https://github.com/new-username/new-repository.git
```
Replace https://github.com/new-username/new-repository.git with the new URL of your remote repository.
Verify the updated remote origin by running the following command:
```
git remote -v
```
This should display the new URL of your remote origin.

Removing the Existing Remote Origin

If you need to completely remove the existing remote origin and set a new one, follow these steps:

Open a terminal and navigate to your local Git repository.
Use the git remote remove command to delete the existing remote origin:
```
git remote remove origin
```
Add the new remote origin using the git remote add command:
```
git remote add origin https://github.com/new-username/new-repository.git
```
Replace https://github.com/new-username/new-repository.git with the URL of your new remote repository.
