Contributors will need to `register for the mailing list <https://mails.dpdk.org/listinfo/dev>`_ in order to submit patches.
It is also worth registering for the DPDK `Patchwork <https://patches.dpdk.org/project/dpdk/list/>`_
-If you are using the GitHub service, you can link your repository to
-the ``travis-ci.org`` build service. When you push patches to your GitHub
-repository, the travis service will automatically build your changes.
+If you are using the GitHub service, pushing to a branch will trigger GitHub
+Actions to automatically build your changes and run unit tests and ABI checks.
+
+Additionally, a Travis configuration is available in DPDK but Travis free usage

The development process requires some familiarity with the ``git`` version control system.

The maintainer should be confirmed by an ``ack`` from an existing tree maintainer.
Disagreements on trees or maintainers can be brought to the Technical Board.
-The backup maintainer for the master tree should be selected from the existing sub-tree maintainers from the project.

+All fix patches to the main branch that are candidates for backporting

In the commit message body the Cc: stable@dpdk.org should be inserted as follows::
The path to the original Linux script must be set in the environment variable ``DPDK_CHECKPATCH_PATH``.
-Spell checking of commonly misspelled words
-can be enabled by downloading the codespell dictionary::
+Spell checking of commonly misspelled words is enabled

Checking Compilation
--------------------
-Makefile System
-~~~~~~~~~~~~~~~
-
-Compilation of patches and changes should be tested using the ``test-build.sh`` script in the ``devtools``
-directory of the DPDK repo::
-
- devtools/test-build.sh x86_64-native-linux-gcc+next+shared
-
-The script usage is::
-
- test-build.sh [-h] [-jX] [-s] [config1 [config2] ...]]
-
-Where:
-
-* ``-h``: help, usage.
-* ``-jX``: use X parallel jobs in "make".
-* ``-s``: short test with only first config and without examples/doc.
-* ``config``: default config name plus config switches delimited with a ``+`` sign.
-
-Examples of configs are::
-
- x86_64-native-linux-gcc
- x86_64-native-linux-gcc+next+shared
- x86_64-native-linux-clang+shared
-
-The builds can be modified via the following environmental variables:
-
-* ``DPDK_BUILD_TEST_CONFIGS`` (target1+option1+option2 target2)
-* ``DPDK_BUILD_TEST_DIR``
-* ``DPDK_DEP_CFLAGS``
-* ``DPDK_DEP_LDFLAGS``
-* ``DPDK_DEP_PCAP`` (y/[n])
-* ``DPDK_NOTIFY`` (notify-send)
-
-These can be set from the command line or in the config files shown above in the :ref:`contrib_checkpatch`.
-
-The recommended configurations and options to test compilation prior to submitting patches are::
-
- x86_64-native-linux-gcc+shared+next
- x86_64-native-linux-clang+shared
- i686-native-linux-gcc
-
- export DPDK_DEP_ZLIB=y
- export DPDK_DEP_PCAP=y
- export DPDK_DEP_SSL=y

Compilation of patches is to be tested with ``devtools/test-meson-builds.sh`` script.
