A compliant README must satisfy all the requirements listed below.
Note: Standard Readme is designed for open source libraries. Although it's historically made for Node and npm projects, it also applies to libraries in other languages and package managers.
Requirements:
- Be called README (with capitalization) and have a specific extension depending on its format (
.md
for Markdown,.org
for Org Mode Markup syntax,.html
for HTML, ...) - If the project supports i18n, the file must be named accordingly:
README.de.md
, wherede
is the BCP 47 Language tag. For naming, prioritize non-regional subtags for languages. If there is only one README and the language is not English, then a different language in the text is permissible without needing to specify the BCP tag: e.g.,README.md
can be in German if there is noREADME.md
in another language. Where there are multiple languages,README.md
is reserved for English. - Be a valid file in the selected format (Markdown, Org Mode, HTML, ...).
- Sections must appear in order given below. Optional sections may be omitted.
- Sections must have the titles listed below, unless otherwise specified. If the README is in another language, the titles must be translated into that language.
- Must not contain broken links.
- If there are code examples, they should be linted in the same way as the code is linted in the rest of the project.
Note: This is only a navigation guide for the specification, and does not define or mandate terms for any specification-compliant documents.
Status: Required.
Requirements:
-
Title must match repository, folder and package manager names - or it may have another, relevant title with the repository, folder, and package manager title next to it in italics and in parentheses. For instance:
# Standard Readme Style _(standard-readme)_
If any of the folder, repository, or package manager names do not match, there must be a note in the Long Description explaining why.
Suggestions:

to show the description from a local npm package.
Status: Optional.
Requirements:
- Must not have its own title.
- If any of the folder, repository, or package manager names do not match, there must be a note here as to why. See Title section.
Suggestions:
-
If too long, consider moving to the 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."
Status: Required; optional for READMEs shorter than 100 lines.
Requirements:
- Must link to all sections in the file.
- Must start with the next section; do not include the title or Table of Contents headings.
- Must be at least one-depth: must capture all level two headings (e.g.: Markdown's
##
or Org Mode's**
or HTML's<h2>
and so on).
Suggestions:
- May capture third and fourth depth headings. If it is a long ToC, these are optional.
Status: Optional.
Requirements:
- May go here if it is important to highlight security concerns. Otherwise, it should be in Extra Sections.
Status: Optional.
Requirements:
- Cover motivation.
- Cover abstract dependencies.
- Cover intellectual provenance: A
See Also
section is also fitting.
Status: Required by default, optional for documentation repositories.
Requirements:
- Code block illustrating how to install.
Subsections:
Dependencies
. Required if there are unusual dependencies or dependencies that must be manually installed.
Suggestions:
- Link to prerequisite sites for programming language: npmjs, godocs, etc.
- Include any system-specific information needed for installation.
- An
Updating
section would be useful for most packages, if there are multiple versions which the user may interface with.
Status: Required by default, optional for documentation repositories.
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.
Status: Optional.
Requirements:
- None.
Suggestions:
- This should not be called
Extra Sections
. This is a space for 0 or more sections to be included, each of which must have their own titles. - This should contain any other sections that are relevant, placed after Usage and before API.
- Specifically, the Security section should be here if it wasn't important enough to be placed above.
Status: Optional.
Requirements:
- Describe exported functions and objects.
Suggestions:
- Describe signatures, return types, callbacks, and events.
- Cover types covered where not obvious.
- Describe caveats.
- If using an external API generator (like go-doc, js-doc, or so on), point to an external
API.md
file. This can be the only item in the section, if present.
Status: Optional.
Requirements:
- Must be called
Maintainer
orMaintainers
. - List maintainer(s) for a repository, along with one way of contacting them (e.g. GitHub link or email).
Suggestions:
- This should be a small list of people in charge of the repo. This should not be everyone with access rights, such as an entire organization, but the people who should be pinged and who are in charge of the direction and maintenance of the repository.
- Listing past maintainers is good for attribution, and kind.
Status: Optional.
Requirements:
- Must be called
Thanks
,Credits
orAcknowledgements

Suggestions:
- State anyone or anything that significantly helped with the development of your project.
- State public contact hyper-links if applicable.
Status: Required.
Requirements:
- State where users can ask questions.
- State whether PRs are accepted.

Suggestions:
- Link to a CONTRIBUTING file -- if there is one.
- Be as friendly as possible.
- Link to the GitHub issues.
- Link to a Code of Conduct. A CoC is often in the Contributing section or document, or set elsewhere for an entire organization, so it may not be necessary to include the entire file in each repository. However, it is highly recommended to always link to the code, wherever it lives.
- A subsection for listing contributors is also welcome here.
Status: Required.
Requirements:
- State license full name or identifier, as listed on the SPDX license list. For unlicensed repositories, add
