Add Info: "How to Backup/Restore Data" to README.md

[k3b]

Hint: in Android studio

• open your clone of the project
• from within android-studio switch to branch "master", from that create a new brach "update-documentation" and switch to that new branch.
• find file "README.md" (this is the text that you see when opening https://github.com/SecUSo/privacy-friendly-finance-manager/ or https://github.com/k3b/privacy-friendly-finance-manager
• Add one small Paragraph at the apropriate place

"You can create a backup of your privacy-friendly-finance-manager database and restore it later with privacy-friendly-backup"

Maybe you find better word for this.

---

after this

• commit your changes to your local copy of the repository
• push your changes to your github repository
• create a merge- request targeting https://github.com/k3b/privacy-friendly-finance-manager

maybe your collegues can help you with this.

This will be done in a "work experience course" by a high school student as an excercise: How to create a git(hub)-branch make changes and create a pullrequest.

I (k3b) am his mentor (an experienced android/java developper)
