    help: fixed overview.page
    
    Due to previous clashes in stashing and unstashing changes, git
    had auto inserted changes and indicated them with text "Upstream
    Changes" in the file. Cleaned them.
    
    Organized review notes into TODOs.

+      <title>Shell</title>
+      <p>A shell is a program that provides an interface to invoke or "launch"
+  commands or another program inside a terminal. It also allows you to view and
+  browse the contents of directories.</p>

+      <title>Prompt</title>
+      <p>A prompt also called a command prompt is a sequence of characters used
+      in the CLI to indicate the readiness of the shell to accept commands.</p>
 
-<!-- What is the connection between a terminal and a shell? Explain. -->
+      <p>A prompt usually ends with characters $, %, # or > and includes
+      information about path of present working directory. On Unix based
+      systems, it is common for the prompt to end in a $ or % character
+      depending on the user role such as $ for user and # for superuser (also
+      called root).</p>

+      <p>Prompts are customisable to include colors, special characters and
+      variables for system time, user, working directory to make the prompt
+      informative and distinguishable from sessions on various machines.</p>
+
+      <p>In a bash shell, the $PS1 variable can be used to set the prompt.
+      <code>[time] user host: work_dir $ export PS1='[\t] \u \H: \W
+      $'</code></p>
