+# How to Contribute
+
+Contributions are welcome! Thank you!
+
+## General Guidelines
+
+Some quick notes when making a pull request.
+
+- Match the style and formatting of the code you are editing.
+- Each pull request should be focused on a single thing (a single bug fix, a single feature, etc.). This makes reviewing easier and minimizes merge conflicts.
+- Include a description of the problem being solved and what your code does. Steps to reproduce the problem or example input/output are very helpful.
+
+## Adding Options
+
+Keeping the wizard as short as possible is a priority. Pull requests that add options to the wizard will probably not be accepted. Instead, you can add an advanced setting to [settings.js](https://github.com/lonekorean/wordpress-export-to-markdown/blob/master/src/settings.js).
+
+## Adding Frontmatter Fields
+
+Similarly, default frontmatter output is limited to just a few widely used fields to avoid bloat. However, you may add new optional frontmatter fields.
+
+To do so, add a new `.js` file into the [/src/frontmatter](https://github.com/lonekorean/wordpress-export-to-markdown/tree/master/src/frontmatter) folder. The filename should be the name of the frontmatter field, camelcased. See the other files there for code examples.
+
+Users will be able to include your new frontmatter field by editing `frontmatter_fields` in [settings.js](https://github.com/lonekorean/wordpress-export-to-markdown/blob/master/src/settings.js).
