Readme Markdown

You just start writing Markdown text, save the file with extension and then you can toggle the visualization of the editor between the code and the preview of the Markdown file; obviously, you can also open an existing Markdown file and start working with it. To switch between views, press Ctrl+Shift+V in the editor. Links look like this in the Markdown editor: And result in a link that looks like this: ReadMe. Reference-Style Linking Reference-style linking allows you to give a link a number or 'name' and refer to it multiple times. For example, if I type in: It looks like this: When I first search something I look at Google then at Yahoo then MSN.

README files can help your users understand your project and can be used to set your project’s description on PyPI.This guide helps you create a README in a PyPI-friendly format and include your README in your package so it appears on PyPI.

Creating a README file¶

README files for Python projects are often named README, README.txt, README.rst, or

For your README to display properly on PyPI, choose a markup language supported by PyPI.Formats supported by PyPI’s README renderer are:

  • plain text

  • reStructuredText (without Sphinx extensions)

  • Markdown (GitHub Flavored Markdown by default,or CommonMark)

It’s customary to save your README file in the root of your project, in the same directory as your file.

Including your README in your package’s metadata¶

To include your README’s contents as your package description,set your project’s Description and Description-Content-Type metadata,typically in your project’s file.

For example, to set these values in a package’s file,use setup()’s long_description and long_description_content_type.

Set the value of long_description to the contents (not the path) of the README file itself.Set the long_description_content_type to an accepted Content-Type-style value for your README file’s markup,such as text/plain, text/x-rst (for reStructuredText), or text/markdown.

Readme Markdown


If you’re using GitHub-flavored Markdown to write a project’s description, ensure you upgradethe following tools:

The minimum required versions of the respective tools are:

  • setuptools>=38.6.0

  • wheel>=0.31.0

  • twine>=1.11.0

It’s recommended that you use twine to upload the project’s distribution packages:

For example, see this file,which reads the contents of as long_descriptionand identifies the markup as GitHub-flavored Markdown:

Validating reStructuredText markup¶

If your README is written in reStructuredText, any invalid markup will preventit from rendering, causing PyPI to instead just show the README’s raw source.

Note that Sphinx extensions used in docstrings, such asdirectives and roles(e.g., “:py:func:`getattr`” or “:ref:`my-reference-label`”), are not allowed here and will result in errormessages like “Error:Unknowninterpretedtextrole'py:func'.”.

You can check your README for markup errors before uploading as follows:

  1. Install the latest version of twine;version 1.12.0 or higher is required:

  2. Build the sdist and wheel for your project as described underPackaging your project.

  3. Run twinecheck on the sdist and wheel:

    This command will report any problems rendering your README. If your markuprenders fine, the command will output CheckingdistributionFILENAME:Passed.

Markdown is a lightweight and easy-to-use syntax for styling all forms of writing on the GitHub platform.

What you will learn:

  • How the Markdown format makes styled collaborative editing easy
  • How Markdown differs from traditional formatting approaches
  • How to use Markdown to format text
  • How to leverage GitHub’s automatic Markdown rendering
  • How to apply GitHub’s unique Markdown extensions

What is Markdown?

Markdown is a way to style text on the web. You control the display of the document; formatting words as bold or italic, adding images, and creating lists are just a few of the things we can do with Markdown. Mostly, Markdown is just regular text with a few non-alphabetic characters thrown in, like # or *.

You can use Markdown most places around GitHub:

  • Comments in Issues and Pull Requests
  • Files with the .md or .markdown extension

For more information, see “Writing on GitHub” in the GitHub Help.


It's very easy to make some words bold and other words italic with Markdown. You can even link to Google!

Syntax guide


Here’s an overview of Markdown syntax that you can use anywhere on or in your own text files.

Inline code

Readme Markdown

GitHub Flavored Markdown uses its own version of the Markdown syntax that provides an additional set of useful features, many of which make it easier to work with content on

Note that some features of GitHub Flavored Markdown are only available in the descriptions and comments of Issues and Pull Requests. These include @mentions as well as references to SHA-1 hashes, Issues, and Pull Requests. Task Lists are also available in Gist comments and in Gist Markdown files.

Syntax highlighting

Here’s an example of how you can use syntax highlighting with GitHub Flavored Markdown:

You can also simply indent your code by four spaces:

Here’s an example of Python code without syntax highlighting:

Task Lists

If you include a task list in the first comment of an Issue, you will get a handy progress indicator in your issue list. It also works in Pull Requests!


You can create tables by assembling a list of words and dividing them with hyphens - (for the first row), and then separating each column with a pipe :

Would become:

First HeaderSecond Header
Content from cell 1Content from cell 2
Content in the first columnContent in the second column

SHA references

Any reference to a commit’s SHA-1 hash will be automatically converted into a link to that commit on GitHub.

Issue references within a repository

Any number that refers to an Issue or Pull Request will be automatically converted into a link.

Readme Markdown Guide

Username @mentions

Typing an @ symbol, followed by a username, will notify that person to come and view the comment. This is called an “@mention”, because you’re mentioning the individual. You can also @mention teams within an organization.

Automatic linking for URLs

Readme Markdown Image

Any URL (like will be automatically converted into a clickable link.


Any word wrapped with two tildes (like ~~this~~) will appear crossed out.


GitHub supports emoji!
