+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
