# Configuration
<mark style="background-color:blue;">**experimental**</mark>
## The `package.json` file
A Pear project **must** have a `package.json` file and a main entry file.
The `package.json` file **must** have either a `name` property or `pear` object with a `name` property.
The `package.json` `name` field must be lowercase and one word, and may contain letters, numbers, hyphens (`-`), underscores (`_`), forward slashes (`/`) and asperands (`@`).
The `package.json` file may also contain a `main` field, which typically should point to an HTML file. If omitted, `index.html` or `index.js` is the default entry file depending on application type.
Any other fields (such as `dependencies`) may also be present in the `package.json` file.
The `package.json` `pear` object contains application configuration and is exposed via the API as `pear.config.options`.
Pear versioning is automatic. The `package.json` file does **not** require a version field, the version field will be ignored.
