+first steps and basic output
+	how shell reads input - three methods
+	use of "echo" built-in utility
+	ex: hello world
+simple commands, field splitting, and quoting
+	ex: maybe cd, mkdir/touch, etc.
+tilde and pathname expansion
+	ex: cd with tildes
+	ex: cd/mkdir/touch with pathname expansions
+parameters
+	defining variables and expanding their values
+	positional parameters, special parameters, and shell variables
+	ex: assign variables
+	ex: expand and print variables and positional parameters
+command substitution
+	ex: commands in subshells, output assigned to variables
+arithmetic expansion
+	ex: some expressions, assignments, etc.
