Configuration File V2¶

Read the Docs supports configuring your documentation builds with a YAML file. The Read the Docs file must be in the root directory of your project.

Here is an example of how this file looks like:

# .readthedocs.yml

version: 2

python:
  version: 3.7
  install:
     - method: pip
       path: .

Supported settings¶

Note

The presence of any other key that isn’t documented here will make the build to fail. This is to avoid typos and provide feedback on invalid configurations.

version¶

Required:	`true`

Example:

version: 2

Warning

If you don’t provide the version, v1 will be used.

formats¶

Formats of the documentation to be built.

Type:	`list`
Options:	`htmlzip`, `pdf`, `epub`
Default:	`[]`

Example:

# Default

  - epub
  - pdf

Note

You can use the all keyword to indicate all formats.

# Build all formats
formats: all

        extra_requirements:
            - docs
      - method: setuptools
        path: another/package
   system_packages: true

python.version¶

python.install¶

List of installation methods of packages and requirements. You can have several of the following methods.

Type:	`list`
Default:	`[]`

Requirements file¶

Install packages from a requirements file.

The path to the requirements file, relative to the root of the project.

Key:	`requirements`

Example:

python:
   version: 3.7
   install:
      - requirements: docs/requirements.txt
      - requirements: requirements.txt

Packages¶

The path to the package, relative to the root of the project.

Key:	`path`
Type:	`path`
Required:	`true`

The installation method.

Key:	`method`
Options:	`pip`, `setuptools`

Extra requirements section to install in addition to the package dependencies.

Warning

You need to install your project with pip to use extra_requirements.

Key:	`extra_requirements`
Type:	`list`
Default:	`[]`

Example:

python:
   version: 3.7

pip install .[docs]
python package/setup.py install

python.system_packages¶

Give the virtual environment access to the global site-packages directory.

Type:	`bool`
Default:	`false`

Depending on the build.image, Read the Docs includes some libraries like scipy, numpy, etc. That you can access to them by enabling this option. See The build environment for more details.

Configuration for Conda support. Example:

conda:
  environment: environment.yml

conda.environment¶

Type:	`bool`
Default:	`false`

mkdocs¶

Configuration for Mkdocs documentation. Example:

mkdocs:
  configuration: mkdocs.yml
  fail_on_warning: false

mkdocs.configuration¶

The path to the mkdocs.yml file, relative to the root of the project.

Type:	`path`

Note

You can use the all keyword to exclude all submodules. This is the same as include: [].

Type:	`bool`
Default:	`false`

Note

This is ignored if there aren’t submodules to clone.

Migrating from v1¶

Changes¶

The version setting is required. See version.
The default value of the formats setting has changed to [] and it doesn’t include the values from the web interface.
The top setting requirements_file was moved to python.install and we don’t try to find a requirements file if the option isn’t present. See Requirements file.
The setting conda.file was renamed to conda.environment. See conda.environment.
The build.image setting now only has two options: latest (default) and stable. See build.image.
The settings python.setup_py_install and python.pip_install were replaced by python.install. And now it accepts a path to the package. See Packages.
The setting python.use_system_site_packages was renamed to python.system_packages. See python.system_packages.
The build will fail if there are invalid keys (strict mode).

Warning

Some values from the web interface are no longer respected, please see Migrating from the web interface if you have settings there.

Migrating from the web interface¶

This should be pretty straightforward, just go to the Admin > Advanced settings, and find their respective setting in here.

Not all settings in the web interface are per version, but are per project. These settings aren’t supported via the configuration file.
