What?
We want to add a way for users to give feedback on the pip docs, while they are using them.

Why?
Our goal is to understand what problem the user is trying to solve, what information is helpful, what is unhelpful, and what is missing. Understanding this will help us improve the pip docs for future users.

How?
Initially, we want to add an email link to each documentation page to encourage users to provide us with feedback. This should be a standout box, and contain a message that is something like this:

Did this article help?

We are currently doing research to improve pip's documentation and would love your feedback.
Please email us and let us know:

  1. What problem were you trying to solve when you came to this page?
  2. What content was useful?
  3. What content was not useful?

Where?
It would be great to include this message either:

  • At the end of each article
  • As a "sticky" message either at the top or right hand side of the page

@webknjaz or @yeraydiazdiaz - would either of you have time to work on this? I'd like to start collecting data asap.

@nlhkabu would something like https://sphinx-version-warning.rtfd.io work?

Is this the banner that would hold the email link?

@webknjaz @nlhkabu
I think it would be preferable to have it in the sidebar, as people might want to give feedback on something they deal with when having scrolled down. Alternatively: Could the banner appear at the bottom of the page? (I guess there it is more likely that the participants already made some experiences with the text and could give feedback on it, whereas, if the banner is on top, they need to remember to give feedback later while solving their problem (or whatever they consult the docs for))

Yes, but if not — making a sticky header shouldn't be too hard.

I think it would be preferable to have it in the sidebar

As in, under the left menu?

FWIW this issue looks like a temporary solution so I'd avoid investing too much time into it knowing that it'll be replaced.

@webknjaz @jdittrich how about a compromise. We include the header at the top and the bottom of the page?
As @webknjaz mentioned, it's a temporary fix, so I don't think we should invest too much time in it.

@jdittrich are you happy with this text?

I've started something at #8848 but it's totally unstyled atm. Decided not to use an external ext.

@nlhkabu do you want full page URLs injected into the widget? The extension I started does not have this info during the build time, it only has the doc name. Adding full URLs will require some client-side JS on top.

@webknjaz Consider avoiding PR / issue references in commits, since they create noise on the original issue when rebasing / forks cherry-pick commits etc.

- Headers provided by wheels in .data directories are now correctly installed
  into the user-provided locations, such as ``--prefix``, instead of the virtual
  environment pip is running in. (`8521 &lt;https://github.com/pypa/pip/issues/8521&gt;`_)

   ```
   
  
  
   ### 20.3b1
   ```
   ===================

Deprecations and Removals
-------------------------

- ``pip freeze`` will stop filtering the ``pip``, ``setuptools``, ``distribute`` and ``wheel`` packages from ``pip freeze`` output in a future version.
  To keep the previous behavior, users should use the new ``--exclude`` option. (`4256 &lt;https://github.com/pypa/pip/issues/4256&gt;`_)
- Deprecate support for Python 3.5 (`8181 &lt;https://github.com/pypa/pip/issues/8181&gt;`_)
- Document that certain removals can be fast tracked. (`8417 &lt;https://github.com/pypa/pip/issues/8417&gt;`_)
- Document that Python versions are generally supported until PyPI usage falls below 5%. (`8927 &lt;https://github.com/pypa/pip/issues/8927&gt;`_)
- Deprecate ``--find-links`` option in ``pip freeze`` (`9069 &lt;https://github.com/pypa/pip/issues/9069&gt;`_)

Features
--------

- Add ``--exclude`` option to ``pip freeze`` and ``pip list`` commands to explicitly exclude packages from the output. (`4256 &lt;https://github.com/pypa/pip/issues/4256&gt;`_)
- Allow multiple values for --abi and --platform. (`6121 &lt;https://github.com/pypa/pip/issues/6121&gt;`_)
- Add option ``--format`` to subcommand ``list`` of ``pip  cache``, with ``abspath`` choice to output the full path of a wheel file. (`8355 &lt;https://github.com/pypa/pip/issues/8355&gt;`_)
- Improve error message friendliness when an environment has packages with
  corrupted metadata. (`8676 &lt;https://github.com/pypa/pip/issues/8676&gt;`_)
- Make the ``setup.py install`` deprecation warning less noisy. We warn only
  when ``setup.py install`` succeeded and ``setup.py bdist_wheel`` failed, as
  situations where both fails are most probably irrelevant to this deprecation. (`8752 &lt;https://github.com/pypa/pip/issues/8752&gt;`_)
- Check the download directory for existing wheels to possibly avoid
  fetching metadata when the ``fast-deps`` feature is used with
  ``pip wheel`` and ``pip download``. (`8804 &lt;https://github.com/pypa/pip/issues/8804&gt;`_)
- When installing a git URL that refers to a commit that is not available locally
  after git clone, attempt to fetch it from the remote. (`8815 &lt;https://github.com/pypa/pip/issues/8815&gt;`_)
- Include http subdirectory in ``pip cache info`` and ``pip cache purge`` commands. (`8892 &lt;https://github.com/pypa/pip/issues/8892&gt;`_)
- Cache package listings on index packages so they are guarenteed to stay stable
  during a pip command session. This also improves performance when a index page
  is accessed multiple times during the command session. (`8905 &lt;https://github.com/pypa/pip/issues/8905&gt;`_)
- New resolver: Tweak resolution logic to improve user experience when
  user-supplied requirements conflict. (`8924 &lt;https://github.com/pypa/pip/issues/8924&gt;`_)
- Support Python 3.9. (`8971 &lt;https://github.com/pypa/pip/issues/8971&gt;`_)
- Log an informational message when backtracking takes multiple rounds on a specific package. (`8975 &lt;https://github.com/pypa/pip/issues/8975&gt;`_)
- Switch to the new dependency resolver by default. (`9019 &lt;https://github.com/pypa/pip/issues/9019&gt;`_)
- Remove the ``--build-dir`` option, as per the deprecation. (`9049 &lt;https://github.com/pypa/pip/issues/9049&gt;`_)

Bug Fixes
---------

- Propagate ``--extra-index-url`` from requirements file properly to session auth,
  so that keyring auth will work as expected. (`8103 &lt;https://github.com/pypa/pip/issues/8103&gt;`_)
- Allow specifying verbosity and quiet level via configuration files
  and environment variables. Previously these options were treated as
  boolean values when read from there while through CLI the level can be
  specified. (`8578 &lt;https://github.com/pypa/pip/issues/8578&gt;`_)
- Only converts Windows path to unicode on Python 2 to avoid regressions when a
  POSIX environment does not configure the file system encoding correctly. (`8658 &lt;https://github.com/pypa/pip/issues/8658&gt;`_)
- List downloaded distributions before exiting ``pip download``
  when using the new resolver to make the behavior the same as
  that on the legacy resolver. (`8696 &lt;https://github.com/pypa/pip/issues/8696&gt;`_)
- New resolver: Pick up hash declarations in constraints files and use them to
  filter available distributions. (`8792 &lt;https://github.com/pypa/pip/issues/8792&gt;`_)
- Avoid polluting the destination directory by resolution artifacts
  when the new resolver is used for ``pip download`` or ``pip wheel``. (`8827 &lt;https://github.com/pypa/pip/issues/8827&gt;`_)
- New resolver: If a package appears multiple times in user specification with
  different ``--hash`` options, only hashes that present in all specifications
  should be allowed. (`8839 &lt;https://github.com/pypa/pip/issues/8839&gt;`_)
- Tweak the output during dependency resolution in the new resolver. (`8861 &lt;https://github.com/pypa/pip/issues/8861&gt;`_)
- Correctly search for installed distributions in new resolver logic in order
  to not miss packages (virtualenv packages from system-wide-packages for example) (`8963 &lt;https://github.com/pypa/pip/issues/8963&gt;`_)
- Do not fail in pip freeze when encountering a ``direct_url.json`` metadata file
  with editable=True. Render it as a non-editable ``file://`` URL until modern
  editable installs are standardized and supported. (`8996 &lt;https://github.com/pypa/pip/issues/8996&gt;`_)

Vendored Libraries
------------------

- Fix devendoring instructions to explicitly state that ``vendor.txt`` should not be removed.
  It is mandatory for ``pip debug`` command.

Improved Documentation
----------------------

- Add documentation for &#39;.netrc&#39; support. (`7231 &lt;https://github.com/pypa/pip/issues/7231&gt;`_)
- Add OS tabs for OS-specific commands. (`7311 &lt;https://github.com/pypa/pip/issues/7311&gt;`_)
- Add note and example on keyring support for index basic-auth (`8636 &lt;https://github.com/pypa/pip/issues/8636&gt;`_)
- Added initial UX feedback widgets to docs. (`8783 &lt;https://github.com/pypa/pip/issues/8783&gt;`_, `8848 &lt;https://github.com/pypa/pip/issues/8848&gt;`_)
- Add ux documentation (`8807 &lt;https://github.com/pypa/pip/issues/8807&gt;`_)
- Update user docs to reflect new resolver as default in 20.3. (`9044 &lt;https://github.com/pypa/pip/issues/9044&gt;`_)
- Improve migration guide to reflect changes in new resolver behavior. (`9056 &lt;https://github.com/pypa/pip/issues/9056&gt;`_)

- New resolver: Tweak resolution logic to improve user experience when
  user-supplied requirements conflict. (`8924 &lt;https://github.com/pypa/pip/issues/8924&gt;`_)
- Support Python 3.9. (`8971 &lt;https://github.com/pypa/pip/issues/8971&gt;`_)

- Switch to the new dependency resolver by default. (`9019 &lt;https://github.com/pypa/pip/issues/9019&gt;`_)
- Remove the ``--build-dir`` option, as per the deprecation. (`9049 &lt;https://github.com/pypa/pip/issues/9049&gt;`_)

Bug Fixes
---------

- Propagate ``--extra-index-url`` from requirements file properly to session auth,
  so that keyring auth will work as expected. (`8103 &lt;https://github.com/pypa/pip/issues/8103&gt;`_)
- Allow specifying verbosity and quiet level via configuration files
  and environment variables. Previously these options were treated as
  boolean values when read from there while through CLI the level can be
  specified. (`8578 &lt;https://github.com/pypa/pip/issues/8578&gt;`_)
- Only converts Windows path to unicode on Python 2 to avoid regressions when a
  POSIX environment does not configure the file system encoding correctly. (`8658 &lt;https://github.com/pypa/pip/issues/8658&gt;`_)
- List downloaded distributions before exiting ``pip download``
  when using the new resolver to make the behavior the same as
  that on the legacy resolver. (`8696 &lt;https://github.com/pypa/pip/issues/8696&gt;`_)
- New resolver: Pick up hash declarations in constraints files and use them to
  filter available distributions. (`8792 &lt;https://github.com/pypa/pip/issues/8792&gt;`_)
- Avoid polluting the destination directory by resolution artifacts
  when the new resolver is used for ``pip download`` or ``pip wheel``. (`8827 &lt;https://github.com/pypa/pip/issues/8827&gt;`_)
- New resolver: If a package appears multiple times in user specification with
  different ``--hash`` options, only hashes that present in all specifications
  should be allowed. (`8839 &lt;https://github.com/pypa/pip/issues/8839&gt;`_)
- Tweak the output during dependency resolution in the new resolver. (`8861 &lt;https://github.com/pypa/pip/issues/8861&gt;`_)
- Correctly search for installed distributions in new resolver logic in order
  to not miss packages (virtualenv packages from system-wide-packages for example) (`8963 &lt;https://github.com/pypa/pip/issues/8963&gt;`_)
- Do not fail in pip freeze when encountering a ``direct_url.json`` metadata file
  with editable=True. Render it as a non-editable ``file://`` URL until modern
  editable installs are standardized and supported. (`8996 &lt;https://github.com/pypa/pip/issues/8996&gt;`_)

Vendored Libraries
------------------

- Fix devendoring instructions to explicitly state that ``vendor.txt`` should not be removed.
  It is mandatory for ``pip debug`` command.

- Added initial UX feedback widgets to docs. (`8783 &lt;https://github.com/pypa/pip/issues/8783&gt;`_, `8848 &lt;https://github.com/pypa/pip/issues/8848&gt;`_)
- Add ux documentation (`8807 &lt;https://github.com/pypa/pip/issues/8807&gt;`_)
- Update user docs to reflect new resolver as default in 20.3. (`9044 &lt;https://github.com/pypa/pip/issues/9044&gt;`_)

   ```
   ===================

Deprecations and Removals
-------------------------

- ``pip freeze`` will stop filtering the ``pip``, ``setuptools``, ``distribute`` and ``wheel`` packages from ``pip freeze`` output in a future version.
  To keep the previous behavior, users should use the new ``--exclude`` option. (`4256 &lt;https://github.com/pypa/pip/issues/4256&gt;`_)
- Deprecate support for Python 3.5 (`8181 &lt;https://github.com/pypa/pip/issues/8181&gt;`_)
- Document that certain removals can be fast tracked. (`8417 &lt;https://github.com/pypa/pip/issues/8417&gt;`_)
- Document that Python versions are generally supported until PyPI usage falls below 5%. (`8927 &lt;https://github.com/pypa/pip/issues/8927&gt;`_)

- Improve error message friendliness when an environment has packages with
  corrupted metadata. (`8676 &lt;https://github.com/pypa/pip/issues/8676&gt;`_)
- Make the ``setup.py install`` deprecation warning less noisy. We warn only
  when ``setup.py install`` succeeded and ``setup.py bdist_wheel`` failed, as
  situations where both fails are most probably irrelevant to this deprecation. (`8752 &lt;https://github.com/pypa/pip/issues/8752&gt;`_)
- Check the download directory for existing wheels to possibly avoid
  fetching metadata when the ``fast-deps`` feature is used with

  after git clone, attempt to fetch it from the remote. (`8815 &lt;https://github.com/pypa/pip/issues/8815&gt;`_)
- Include http subdirectory in ``pip cache info`` and ``pip cache purge`` commands. (`8892 &lt;https://github.com/pypa/pip/issues/8892&gt;`_)
- Cache package listings on index packages so they are guarenteed to stay stable
  during a pip command session. This also improves performance when a index page
  is accessed multiple times during the command session. (`8905 &lt;https://github.com/pypa/pip/issues/8905&gt;`_)
- New resolver: Tweak resolution logic to improve user experience when
  user-supplied requirements conflict. (`8924 &lt;https://github.com/pypa/pip/issues/8924&gt;`_)
- Support Python 3.9. (`8971 &lt;https://github.com/pypa/pip/issues/8971&gt;`_)
- Log an informational message when backtracking takes multiple rounds on a specific package. (`8975 &lt;https://github.com/pypa/pip/issues/8975&gt;`_)
- Switch to the new dependency resolver by default. (`9019 &lt;https://github.com/pypa/pip/issues/9019&gt;`_)
- Remove the ``--build-dir`` option, as per the deprecation. (`9049 &lt;https://github.com/pypa/pip/issues/9049&gt;`_)

Bug Fixes
---------

- Propagate ``--extra-index-url`` from requirements file properly to session auth,
  so that keyring auth will work as expected. (`8103 &lt;https://github.com/pypa/pip/issues/8103&gt;`_)
- Allow specifying verbosity and quiet level via configuration files
  and environment variables. Previously these options were treated as
  boolean values when read from there while through CLI the level can be
  specified. (`8578 &lt;https://github.com/pypa/pip/issues/8578&gt;`_)
- Only converts Windows path to unicode on Python 2 to avoid regressions when a
  POSIX environment does not configure the file system encoding correctly. (`8658 &lt;https://github.com/pypa/pip/issues/8658&gt;`_)
- List downloaded distributions before exiting ``pip download``
  when using the new resolver to make the behavior the same as
  that on the legacy resolver. (`8696 &lt;https://github.com/pypa/pip/issues/8696&gt;`_)
- New resolver: Pick up hash declarations in constraints files and use them to
  filter available distributions. (`8792 &lt;https://github.com/pypa/pip/issues/8792&gt;`_)
- Avoid polluting the destination directory by resolution artifacts
  when the new resolver is used for ``pip download`` or ``pip wheel``. (`8827 &lt;https://github.com/pypa/pip/issues/8827&gt;`_)
- New resolver: If a package appears multiple times in user specification with
  different ``--hash`` options, only hashes that present in all specifications
  should be allowed. (`8839 &lt;https://github.com/pypa/pip/issues/8839&gt;`_)
- Tweak the output during dependency resolution in the new resolver. (`8861 &lt;https://github.com/pypa/pip/issues/8861&gt;`_)
- Correctly search for installed distributions in new resolver logic in order
  to not miss packages (virtualenv packages from system-wide-packages for example) (`8963 &lt;https://github.com/pypa/pip/issues/8963&gt;`_)
- Do not fail in pip freeze when encountering a ``direct_url.json`` metadata file
  with editable=True. Render it as a non-editable ``file://`` URL until modern
  editable installs are standardized and supported. (`8996 &lt;https://github.com/pypa/pip/issues/8996&gt;`_)

Vendored Libraries
------------------

- Fix devendoring instructions to explicitly state that ``vendor.txt`` should not be removed.
  It is mandatory for ``pip debug`` command.

Improved Documentation
----------------------

- Add documentation for &#39;.netrc&#39; support. (`7231 &lt;https://github.com/pypa/pip/issues/7231&gt;`_)
- Add OS tabs for OS-specific commands. (`7311 &lt;https://github.com/pypa/pip/issues/7311&gt;`_)
- Add note and example on keyring support for index basic-auth (`8636 &lt;https://github.com/pypa/pip/issues/8636&gt;`_)
- Added initial UX feedback widgets to docs. (`8783 &lt;https://github.com/pypa/pip/issues/8783&gt;`_, `8848 &lt;https://github.com/pypa/pip/issues/8848&gt;`_)
- Add ux documentation (`8807 &lt;https://github.com/pypa/pip/issues/8807&gt;`_)
- Update user docs to reflect new resolver as default in 20.3. (`9044 &lt;https://github.com/pypa/pip/issues/9044&gt;`_)
- Improve migration guide to reflect changes in new resolver behavior. (`9056 &lt;https://github.com/pypa/pip/issues/9056&gt;`_)
