+## Introduction
 
 This repository is a GitHub template repository for creating software project repositories at the Caltech Library.  The [associated wiki page](https://github.com/caltechlibrary/template/wiki/Using-this-template-repo) explains how to use the template repository.
 
 This README file is in Markdown format, and is meant to provide a template for README files as well an illustration of what the README file can be expected to look like.  For a software project, this [Introduction](#introduction) section – which you are presently reading – should provide background for the project, a brief explanation of what the project is about, and optionally, pointers to resources that can help orient readers.  Ideally, this section should be short.

+## Installation
 
 Begin this section by mentioning any prerequisites that may be important for users to have before they can use your software.  Examples include hardware and operating system requirements.

 Some projects need to communicate additional information to users and can benefit from additional sections in the README file.  It's difficult to give specific instructions – a lot depends on your software, your intended audience, etc.  Use your judgment and ask for feedback from users or colleagues to help figure out what else is worth explaining.
 
 
-Known issues and limitations
-----------------------------
+## Known issues and limitations
 
 In this section, summarize any notable issues and/or limitations of your software.  If none are known yet, this section can be omitted (and don't forget to remove the corresponding entry in the [Table of Contents](#table-of-contents) too); alternatively, you can leave this section in and write something along the lines of "none are known at this time".
 
 
-Getting help
-------------
+## Getting help
 
 Inform readers of how they can contact you, or at least how they can report problems they may encounter.  This may simply be a request to use the issue tracker on your repository, but many projects have associated chat or mailing lists, and this section is a good place to mention those.
 
 
-Contributing
-------------
+## Contributing
 
 This section is optional; if your repository is for a project that accepts open-source contributions, then this section is where you can mention how people can offer contributions, and point them to your guidelines for contributing.  (If you delete this section, don't forget to remove the corresponding entry in the [Table of Contents](#table-of-contents) too.)

+## Authors and history
 
 In this section, list the authors and contributors to your software project.  Adding additional notes here about the history of the project can make it more interesting and compelling.  This is also a place where you can acknowledge other contributions to the work and the use of other people's software or tools.
