I usually start developing a new project locally, then later create a git repository and add the code to it. I can never remember the sequence of commands to do that so have to Google them every time. Whilst one (possibly the simplest) approach is to create a new GitHub repository, clone it locally and then copy and paste the code from it’s existing location, the other (more correct) approach is detailed below.
First, create a new GitHub repository for the existing project. Make a note of the GitHub URL for the repository as you’ll need this later.
Next, initialise the local repository. From a command prompt in the root of your local repository use:
git initIf you haven’t already got one, now would be a good time to create a .gitignore file. For DotNet projects this can be done using dotnet new gitignore
Next, add all the files to it using:
git add .The . tells git to add all files
Then commit all the files:
git commit -m "Initial commit"Feel free to use a more descriptive commit message
Add a remote reference for GitHub:
git remote add origin https://github.com/{github-user-name}/{repository-name}.gitThe last section of that command is the repository’s GitHub URL. If using SSH, this can be replaced with git@github.com:{github-user-name}/{repository-name}.git, though you will need to have a public SSH key set up for your GitHub account for this to work
Finally, push the first commit to GitHub:
git push -u -f origin mainThe -u flag makes the remote GitHub repository the default for your existing project, whilst the -f flag forces git to overwrite any files that already exist on GitHub with your project’s files. This is useful if you created a README.md file
