-So you've been working on a project for a while, and decide you want to put it in a Git repository.
-
-Here's how to do it! First, you initialize a new Git repository in your current directory:
-
-    git init
-
-Then say that you want to record the current state of all files:
-
-    git add .
-
-And then you make a commit, which gives the current state a description, a date, and your name:
-
-    git commit
-

-mkdir recipes
-echo -e "blueberries\nflour" > recipes/blueberry_cake.txt
-echo -e "water\ncarrots" > recipes/carrot soup.txt
-echo "Very good recipes!" > README.md
