`fatal: Not a valid object name: 'master'` when creating a new branch in git

Question

I followed this tutorial but I'm having trouble creating a new branch in a new repository. This is the error I'm getting:

What am I doing wrong?

Answer 1

1. To create a git repository locally, you have to be inside the project directory, then run git init command.

2. To add a file to git, you have to create a file, with some text editor for example. Then you have to add that file to git, then commit it locally.

   git add .
   
   git commit -m "A short description what you did to the file"

UPDATED based on the question update :

To create a git repository for a project

1. First you have to create a project directory.
2. Then from inside the directory, you have to issue git init to initialize a git repo for that project
3. By default, you will be in master branch, to create another branch, use git branch <new branch name>

To add new files to the created repository

1. Create new files like you create for a project.
2. Add those file to git using git add .
3. To commit the file, use git commit -m "a Short description about the action you performed"

Answer 2

1. Initialize a git repository (directory/folder on your computer)
   Navigate to this directory. Then use git init.
2. After you create files in this directory
   git add .
3. Commit the changes
   git commit -m "your message"

Code recap:

git init
git add .
git commit -m "your message"
