 # DEVELOPER INSTRUCTIONS
 
-Most users do not need to build yt-dlp and can [download the builds](https://github.com/yt-dlp/yt-dlp/releases) or get them via [the other installation methods](README.md#installation).
+Most users do not need to build yt-dlp and can [download the builds](https://github.com/yt-dlp/yt-dlp/releases), get them via [the other installation methods](README.md#installation) or directly run it using `python -m yt_dlp`.
 
-To run yt-dlp as a developer, you don't need to build anything either. Simply execute
+`yt-dlp` uses [`hatch`](<https://hatch.pypa.io>) as a project management tool.
+You can easily install it using [`pipx`](<https://pipx.pypa.io>) via `pipx install hatch`, or else via `pip` or your package manager of choice. Make sure you are using at least version `1.10.0`, otherwise some functionality might not work as expected.
 
-    python3 -m yt_dlp
+If you plan on contributing to `yt-dlp`, best practice is to start by running the following command:
 
-To run all the available core tests, use:
+```shell
+$ hatch run setup
+```
 
-    python3 devscripts/run_tests.py
+The above command will install a `pre-commit` hook so that required checks/fixes (linting, formatting) will run automatically before each commit. If any code needs to be linted or formatted, then the commit will be blocked and the necessary changes will be made; you should review all edits and re-commit the fixed version.
+
+After this you can use `hatch shell` to enable a virtual environment that has `yt-dlp` and its development dependencies installed.
+
+In addition, the following script commands can be used to run simple tasks such as linting or testing (without having to run `hatch shell` first):
+* `hatch fmt`: Automatically fix linter violations and apply required code formatting changes
+    * See `hatch fmt --help` for more info
+* `hatch test`: Run extractor or core tests
+    * See `hatch test --help` for more info
 
 See item 6 of [new extractor tutorial](#adding-support-for-a-new-site) for how to run extractor specific test cases.
 
+While it is strongly recommended to use `hatch` for yt-dlp development, if you are unable to do so, alternatively you can manually create a virtual environment and use the following commands:
+
+```shell
+# To only install development dependencies:
+$ python -m devscripts.install_deps --include dev
+
+# Or, for an editable install plus dev dependencies:
+$ python -m pip install -e ".[default,dev]"
+
+# To setup the pre-commit hook:
+$ pre-commit install
+
+# To be used in place of `hatch test`:
+$ python -m devscripts.run_tests
+
+# To be used in place of `hatch fmt`:
+$ ruff check --fix .
+$ autopep8 --in-place .
+
+# To only check code instead of applying fixes:
+$ ruff check .
+$ autopep8 --diff .
+```
+
 If you want to create a build of yt-dlp yourself, you can follow the instructions [here](README.md#compile).

+1. Make sure your code follows [yt-dlp coding conventions](#yt-dlp-coding-conventions), passes [ruff](https://docs.astral.sh/ruff/tutorial/#getting-started) code checks and is properly formatted:
 
-        $ flake8 yt_dlp/extractor/yourextractor.py
+    ```shell
+    $ hatch fmt --check
+    ```
+
+    You can use `hatch fmt` to automatically fix problems. Rules that the linter/formatter enforces should not be disabled with `# noqa` unless a maintainer requests it. The only exception allowed is for old/printf-style string formatting in GraphQL query templates (use `# noqa: UP031`).
 
 1. Make sure your code works under all [Python](https://www.python.org/) versions supported by yt-dlp, namely CPython and PyPy for Python 3.8 and above. Backward compatibility is not required for even older versions of Python.
 1. When the tests pass, [add](https://git-scm.com/docs/git-add) the new files, [commit](https://git-scm.com/docs/git-commit) them and [push](https://git-scm.com/docs/git-push) the result, like this:
 
-        $ git add yt_dlp/extractor/_extractors.py
+    ```shell
-        $ git add yt_dlp/extractor/yourextractor.py
+    $ git add yt_dlp/extractor/_extractors.py

-        $ git push origin yourextractor
+    $ git commit -m '[yourextractor] Add extractor'
+    $ git push origin yourextractor

 1. Finally, [create a pull request](https://help.github.com/articles/creating-a-pull-request). We'll then review and merge it.

 Formats for which the value is not known are excluded unless you put a question mark (`?`) after the operator. You can combine format filters, so `-f "bv[height<=?720][tbr>500]"` selects up to 720p videos (or videos where the height is not known) with a bitrate of at least 500 kbps. You can also use the filters with `all` to download all formats that satisfy the filter, e.g. `-f "all[vcodec=none]"` selects all audio-only formats.

 **Deprecation warning**: Many of these fields have (currently undocumented) aliases, that may be removed in a future version. It is recommended to use only the documented field names.
 
 All fields, unless specified otherwise, are sorted in descending order. To reverse this, prefix the field with a `+`. E.g. `+res` prefers format with the smallest resolution. Additionally, you can suffix a preferred value for the fields, separated by a `:`. E.g. `res:720` prefers larger videos, but no larger than 720p and the smallest video if there are no videos less than 720p. For `codec` and `ext`, you can provide two preferred values, the first for video and the second for audio. E.g. `+codec:avc:m4a` (equivalent to `+vcodec:avc,+acodec:m4a`) sets the video codec preference to `h264` > `h265` > `vp9` > `vp9.2` > `av01` > `vp8` > `h263` > `theora` and audio codec preference to `mp4a` > `aac` > `vorbis` > `opus` > `mp3` > `ac3` > `dts`. You can also make the sorting prefer the nearest values to the provided by using `~` as the delimiter. E.g. `filesize~1G` prefers the format with filesize closest to 1 GiB.
 
-The fields `hasvid` and `ie_pref` are always given highest priority in sorting, irrespective of the user-defined order. This behaviour can be changed by using `--format-sort-force`. Apart from these, the default order used is: `lang,quality,res,fps,hdr:12,vcodec:vp9.2,channels,acodec,size,br,asr,proto,ext,hasaud,source,id`. The extractors may override this default order, but they cannot override the user-provided order.

-Note that the default has `vcodec:vp9.2`; i.e. `av1` is not preferred. Similarly, the default for hdr is `hdr:12`; i.e. dolby vision is not preferred. These choices are made since DV and AV1 formats are not yet fully compatible with most devices. This may be changed in the future as more devices become capable of smoothly playing back these formats.

 If your format selector is `worst`, the last item is selected after sorting. This means it will select the format that is worst in all respects. Most of the time, what you actually want is the video with the smallest filesize instead. So it is generally better to use `-f best -S +size,+br,+res,+fps`.
