# Authors and Instructors

You don't have to write a whole book to use the Runestone tools. Your task can be as simple as having a few examples ready to demonstrate to the class, or as complex as an entirely new book.

If you want to use one of our free and open source books for your class, you can do that too. You can create a book for your own course, or simply use one of the books in our library

## A Classroom Example

Suppose you wanted to have an example program that you could start class with, and then edit and change during the course of the class. Here is how you would create a simple page for you and your class to load into the browser and experiment with.

```Approximating pi
================

.. activecode:: pi_example1

terms=input("How many terms do you wish?")
pi = 0.0
den = 1
for counter in range(terms):
nextterm = (4.0/den)*(-1)**counter
pi = pi + nextterm
den = den + 2
print pi

def leibniz(terms):
acc = 0.0
num = 4.0
den = 1
for term in range(terms):
nextterm = num/den * (-1)**term
acc = acc + nextterm

den = den + 2

return acc

Try running the code above with different values for the
number of terms.  How many terms do you need in order to get
3.14159 for the value of pi?
```

After you install the RunestoneTools, as described below. You can save the example above to a file. When you run the `paver build` command, you will get an html file that you can load into your browser. It will look like this:

## An in Class Quiz

Another Scenario might be that you want to have your students take a quick online quiz that looks like this: You can create a quiz using the same simple markup language used in the previous example.
```A Short Quiz
============

.. mchoice:: question1_1
:correct: a
:feedback_a: Yes, Python is a great language to learn, whether you are a beginner or an experienced programmer.
:feedback_b: Java is a good object oriented language but it has some details that make it hard for the beginner.
:feedback_c: C is an imperative programming language that has been around for a long time, but it is not the one that we use.
:feedback_d: No, ML is a functional programming language.  You can use Python to write functional programs as well.

.. mchoice:: question1_2
:correct: a,b,d
:feedback_a: Red is a definitely on of the colors.
:feedback_b: Yes, yellow is correct.
:feedback_c: Remember the acronym...ROY G BIV.  B stands for blue.
:feedback_d: Yes, green is one of the colors.

Which colors might be found in a rainbow? (choose all that are correct)

```

# Getting Started

Get the Template Project
The quickest way to get up and running is to install the runestone tools with pip: `pip install runestone`
Create a Folder for your project
`mkdir myproj` You can initialize a template project for yourself by running `runestone init` inside the project folder. It will ask you some questions. You can either take the defaults or customize your project for your own environment.
Edit
The template project has an index.rst file ready to edit. You can simply start with the index or overview file and build up from there.
Build
The `runestone build` command will create a nice looking html file for you in the build directory under the template project. Once you have built you can preview that file directly in your browser.
Deploy
You can serve your project right from your own computer by running `runestone serve` Or you can copy the folder in the build subdirectory created by the build command anywhere that will serve a static website, including a site that supports github pages.

• We have a full set of developer docs here
• For a quick reference type `runestone help list` or `runestone help directivename` For example:
```    \$ runestone help codelens

.. codelens:: uniqueid
:tracedata: Autogenerated or provided
:caption: caption below
:showoutput: show stdout from program
:question: Text of question to ask on breakline
:correct: correct answer to the question
