+## you'll be prompted to a couple of times. Press enter for the first prompt. choose a passphrase for the second prompt, or press enter twice for no passphrase

+</code>
+===== Creating a personal access token =====
+NOTE: As a security precaution, GitHub automatically removes personal access tokens that haven't been used in a year.
+https://docs.github.com/en/github/authenticating-to-github/creating-a-personal-access-token
+  - In the upper-right corner of any page, click your profile photo, then click Settings.
+  - In the left sidebar, click Developer settings.
+  - In the left sidebar, click Personal access tokens.
+  - Click Generate new token.
+  - Give your token a descriptive name.
+  - Select the scopes, or permissions, you'd like to grant this token. To use your token to access repositories from the command line, select repo.
+  - Click Generate token.
+  - Click to copy the token to your clipboard. For security reasons, after you navigate off the page, you will not be able to see the token again.
+Warning: Treat your tokens like passwords and keep them secret. When working with the API, use tokens as environment variables instead of hardcoding them into your programs.
+===== Using a token on the command line =====
+Once you have a token, you can enter it instead of your password when performing Git operations over HTTPS.
+For example, on the command line you would enter the following:
+<code>
+$ git clone https://github.com/username/repo.git
+Username: your_username
+Password: your_token
+</code>
+===== Removing git history =====
+<code>
+git checkout --orphan newBranch
+git add -A  # Add all files and commit them
+git commit
+git branch -D master  # Deletes the master branch
+git branch -m master  # Rename the current branch to master
+git push -f origin master  # Force push master branch to github
+git gc --aggressive --prune=all     # remove the old files
+#rename url on github.com if desired, then update the url:
+git remote set-url origin newURL
+</code>
+===== Rebase with fork master =====
+Example fork of repo mainuser/interestingrepo to myuser/interestingrepo
+<code>
+git clone git@github.com:myuser/interestingrepo.git
+cd interestingrepo
+git remote add upstream git@github.com:mainuser/interestingrepo.git
+</code>
+To update:
+<code>
+git fetch upstream
+git rebase upstream/master
+</code>
+===== Change last commit message =====
+<code>
+git commit --amend -m "New message"
+git push --force repository-name branch-name
+</code>
+===== Git Credentials =====
+<code>git config credential.helper store</code>
+then:
+<code>
+git push http://example.com/repo.git
+Username: <type your username>
+Password: <type your password>
+[several days later]
+git push http://example.com/repo.git
+[your credentials are used automatically]
+</code>
+Passwords stored in plain text, each on their own line in URL format:
+<code ~/.git-credentials>
+https://user:pass@example.com
+</code>
+===== Forceful undo last commit =====
+<code>
+git reset --hard HEAD^
+git push origin -f
