Ignoring files and directories
Git has a feature that allows you to ignore files and directories by placing a file named .gitignore in the root of your repository. This file contains a list of patterns that Git will use to determine which files and directories to ignore.
Example .gitignore file
# We are working on a Mac
.DS_Store
# Ignore all .txt files
*.txt
# Ignore all files in the temp directory
temp/
# Ignore node_modules directory
node_modules/
