+    > check out the Markdown CheatSheet for standard syntax 
+    > [Cheat Sheet for Markdown](https://www.markdownguide.org/cheat-sheet/)
+    {: .callout}
+    ~~~

+2. Refer to a different episode 
+

+
+3. Show me some source code
+
+    ~~~
+    for thing in collection:
+        do_something
+    ~~~
+    {: .source}
+
+    or you can use specific language specifiers like `{: .language-python}`
+
+    Please write code so that people can copy directly over to their terminal to run it.  No terminal prompts at the beginning of lines.
+
+    ---
+
+4. Ask me a tricky question 
+
+    ~~~
+    > ## Challenge Title
+    >
+    >  What happens if I type?
+    >
+    > ~~~
+    > rm -rf *
+    > ~~~
+    > {: .source}
+    >
+    > > ## Solution
+    > >
+    > > This is a bad thing to do
+    > >
+    > > ~~~
+    > > You have deleted all your files
+    > > ~~~
+    > > {: .output}
+    > {: .solution}
+    {: .challenge}
+    ~~~
+    {: .source}

+
+5. Make certain you can version things so the lesson is easy to keep up to date.
+
+    ~~~
+    export CODE_VERSION=v20
+    ~~~
+    {: .language-bash}
+
+    Allows you to do 
+
+    ~~~
+    setup $CODE_VERSION
+    ~~~
+    {: .language-bash}
+
+    throughout your lesson. 
+
+    (Visual code and other editors also allow you to do global changes if you have to. )
