==============
This repository shows how to create a lesson using
the [Software Carpentry lesson template][swc-lesson-template],
and is itself an example of the use of that template.
1. Do *not* fork this repository directly on GitHub.
Instead, please follow the instructions below
to create a repository for your lesson from
the [lesson template][swc-lesson-template].
2. Once you have created the repository,
please go through [the layout instructions](LAYOUT.md) to format your lesson.
3. Please keep the master copy of your lesson in your repository's `gh-pages` branch,
since that is what is
[automatically published as a website by GitHub](https://help.github.com/articles/creating-project-pages-manually/).
To simplify reviewing,
please make changes in feature branches
and then submit pull requests against the `gh-pages` branch of your lesson's repository.
We will assume that your user ID is `gvwilson` and the name of your
lesson is `data-cleanup`.
1. Go to [GitHub's importer][import].
2. Click on "Check the URL". (GitHub won't import until you've done this.)
3. Select the owner for your new repository.
In our example this is `gvwilson`,
but it may instead be an organization you belong to.
4. Choose a name for your lesson repository.
In our example, this is `data-cleanup`.
5. Make sure the repository is public.
6. At this point, you should have a page like this:
You can now click "Begin Import".
When the process is done,
you can click "Continue to repository" to visit your newly-created repository.
7. Clone your newly-created repository to your desktop:
~~~
$ git clone -b gh-pages https://github.com/gvwilson/data-cleanup.git
~~~
Note that the URL for your lesson will be different than the one above.
8. Go into that directory using:
~~~
$ cd data-cleanup
~~~
Note that the name of your directory will be different,
since your lesson probably won't be called `data-cleanup`.
9. Manually add the lesson template repository as a remote called `template`:
~~~
$ git remote add template https://github.com/swcarpentry/lesson-template.git
~~~
This will allow you to pull in changes made to the template,
such as improvements to our CSS style files.
(Note that the user name above is `swcarpentry`, *not* `gvwilson`,
since you are adding the master copy of the template as a remote.)
[Lesson Layout](LAYOUT.md),
[Background and Design](DESIGN.md),
and the [FAQ](FAQ.md).
~~~
$ make preview
~~~
This step requires you to have installed Pandoc (described below).
It is *not* optional: you *must* build the web pages for your
lesson yourself and push them to GitHub, rather than relying on
GitHub to build them for you.
12. Commit your changes *and the HTML pages in the root directory of
your lesson repository* and push to the `gh-pages` branch of your
repository:
~~~
$ git commit -m "Explanatory message"
$ git push origin gh-pages
~~~
13. [Tell us](#getting-and-giving-help) where your lesson is so that we can add it to
[the Software Carpentry lessons page][swc-lessons-page].
**Note:** SSH cloning (rather than the HTTPS cloning used above)
will also work for those who have set up SSH keys with GitHub.
**Note:** Once a lesson has been created, please submit changes
for review as pull requests that contain *only the modified Markdown files*,
and *not* the re-generated HTML. This simplifies review considerably,
since each change appears only once. Once the change has been approved,
the lesson maintainer(s) will merge the pull request, re-generate the HTML
locally, and pus that to GitHub.
**Note:**
some people have had intermittent errors during the import process,
possibly because of the network timing out.
If you experience a problem, please re-try;
if the problem persists,
please [get in touch](#getting-and-giving-help).
## Dependencies
Because people may choose to use the IPython Notebook, R Markdown, or
some other format for parts of their lessons, and because Jekyll (the
tool GitHub uses to build HTML pages) only supports an impoverished
form of Markdown, we require lesson authors to build the HTML pages
for their lessons on their machines with Pandoc and commit those to
the `gh-pages` branch of their lesson website. To do this:
1. [Install Pandoc](http://www.pandoc.org/installing)
2. All Python packages required for lesson creation and validation can
be installed using:
$ pip install -r requirements.txt
3. To convert Markdown files into HTML pages in the root directory, go
into the root directory of your lesson and run:
~~~
$ make preview
~~~
You can run `make` on its own to get a list of other things it will
do for you.
We organize our lessons in a standard way so that:

designers. Requiring learning objectives, challenges, and a short
glossary tells people what they ought to create.

them the same look and feel.

## Why Is This Example and Documentation Separate from the Template?
We want it to be easy for authors to merge changes
made to the [lesson template][swc-lesson-template]
into their lesson.
If the lesson template contained all of the documentation in this example,
then every time a merge was done,
authors would have to re-delete those files,
undo merges into their lesson's `README.md`,
etc.
We hope that putting the core files in a repository of their own
will avoid this problem.
(Note that from Fall 2014 to Spring 2015 we tried using two branches in a single repository,
one for the core files and one for the example.
Many contributors [found it confusing](https://github.com/swcarpentry/lesson-template/issues/118);
we hope that separate repositories will be easier to keep straight.)
## Lesson Structure
Instead of putting the whole lesson in one page, authors should create
one short page per topic. Each topic should take 10-15 minutes to
cover, and that coverage to include:
1. Explain the topic's objectives.
2. Perform the material. (We expect instructors to code live, *not*
to put lesson notes or slides on the screen.)
3. Do one or more challenges depending on time.
Along with the lesson materials themselves, each lesson must contain:
* A *reference guide* that learners can use during the lesson and take
away afterward. This must include a glossary of terms, not only to
help learners, but also to help lesson authors summarize what the
lesson actually covers.

* A *discussion page* that mentions more advanced ideas and tells
learners where to go next.
* An *instructor's guide* that presents the lesson's back
story, summarizes our experiences with the lesson, and discusses
solutions to the challenge exercises. We ask everyone who teaches
for us to review and update the instructor's guide for each lesson
they taught after each workshop.
Note that the this means the solutions to the lesson's challenge
exercises will be up on the web. We have chosen to do this
because we believe in openness, and because there's no point
trying to hide something that's in a publicly-readable repository.
Authors may retain copyright on their lessons, but we ask that all
lessons be published under the Creative Commons - Attribution (CC-BY)
license, or put in the public domain (CC-0), to permit remixing.
