## Sections

### Title
**Status:** Required.

**Requirements:**
- Title must match repository and package manager names. If any of these don't match, there must be a note in the [Long Description](#long-description) explaining why.

**Suggestions:**
- Should be self-evident.

### Banner
**Status:** Optional.

**Requirements:**
- Does not require its own title.
- Must link to local image in current repository.
- Must appear directly after the title.

### Badges
**Status:** Optional.

**Requirements:**
- Does not require a title of its own.
- Must be newline delimited.

**Suggestions:**
- Use http://shields.io or a similar service to create and host the images.

### Short Description
**Status:** Required.

**Requirements:**
- Does not require its own title.
- Must be less than 120 characters.
- Must start with `> `
- Must be on it's own line.
- Must match the description in the packager manager's `description` field.
- Must match GitHub's description (if on GitHub).

**Suggestions:**
- Use [gh-description](https://github.com/RichardLitt/gh-description) to set and get GitHub description.
- Use `npm show . description` to show the description from a local [npm](https://npmjs.com) package.

### Long Description
**Status:** Optional.

**Requirements:**
- Does not require its own title.

**Suggestions:**
- If too long, consider moving to the [Background](#background) section.
- Cover the main reasons for building the repository.
- "This should describe your module in broad terms,
generally in just a few paragraphs; more detail of the module's
routines or methods, lengthy code examples, or other in-depth
material should be given in subsequent sections.

  Ideally, someone who's slightly familiar with your module should be
able to refresh their memory without hitting "page down". As your
reader continues through the document, they should receive a
progressively greater amount of knowledge."

### Table of Contents
**Status:** Required by default, optional for READMEs less than 100 lines.

**Requirements:**
- Must link to all Markdown sections in the file.
- Must start with the next section; do not include the title or Table of Contents headings.

**Suggestions:**
- May capture third and fourth depth headings. If it is a long ToC, these are optional.

**Subsections:**
- `Dependencies`. Required if there are unusual dependencies or dependencies that must be manually installed.
- `Updating`. Optional.

**Suggestions:**
- Link to prerequisite sites for programming language: [npmjs](https://npmjs.com), [godocs](https://godoc.org), etc.

- If there is no code in the module - for instance, a document-based module - this section is not required.

### Usage
**Status:** Required by default, optional for doc modules.

**Requirements:**
- Code block illustrating common usage.
- If CLI compatible, code block indicating common usage.
- If importable, code block indicating both import functionality and usage.

**Subsections:**
- `CLI`. Required if CLI functionality exists.

**Suggestions:**
- Cover basic choices that may affect usage: for instance, if JavaScript, cover promises/callbacks, ES6 here.
- If relevant, point to a runnable file for the usage code.
- If there is no code in the module - for instance, a document-based module - this section is not required.

### Extra Sections
**Status**: Optional.

**Requirements:**
- None.

**Suggestions:**
- Does not require its own title, however the sections included within it must have titles.
- This should contain any other sections that are relevant, placed after [Usage](#usage) and before [API](#api).

**Requirements:**
- Describe exported functions and objects.

**Suggestions:**
- Describe signatures, return types, callbacks, and events.
- Cover types covered where not obvious.
- Describe caveats.

### Contribute
**Status**: Required.

**Requirements:**
- State where users can ask questions.
- State whether PRs are accepted.
- List any requirements for contributing; for instance, having a sign-off on commits.

**Suggestions:**
- Link to a contributing or contribute file -- if there is one.
