 __git inti__ initializes a .git to enable you to work on git commands

 ```
 
 ___ git add . __  and __git commit -m "commit message__ means we are adding all file changes and then writing the changes we made on a commit message respectively.
 Git add moves the files to a **staging** area. Git commit now makes them permanent of the current state.

+### Cheat Sheet
+
+    diff
+        diff is used to find differences between two files. On its own, it’s a bit hard to use; instead, use it with diff -u to find lines which differ in two files:
+
+    diff -u
+        diff -u is used to compare two files, line by line, and have the differing lines compared side-by-side in the same output. See below:
+
+            ~$ cat menu1.txt 
+            Menu1:
+
+            Apples
+            Bananas

+    Patch
+        Patch is useful for applying file differences. See the below example, which compares two files. The comparison is saved as a .diff file, which is then patched to the    original file!
