+## The Linux Terminal
+
+Starting the terminal presents itself with a line where you can enter a command:
+```sh
+michael@myComputer>
+```
+Often written, for covenience, as:
+```sh
+$
+```
+When you open your terminal (git shell) and unless otherwise configured, you are located
+in your home directory, denoted as `~/`.
+
+
+## Essential Linux commands
+
+List the contents of a directory
+```sh
+$ ls
+```
+
+Change the directory to a specific folder
+```sh
+$ cd myDirectory
+```
+
+Change the directory 1 level and 2 levels up
+```sh
+$ cd ..
+$ cd ../..
+```
+Create a directory
+```sh
+$ mkdir myNewDirectory
+```
