+# Building manylinux2014 wheels
+
+**WARNING:** To cause everything to be rebuilt, this script will delete ALL changes to the
+repository, including both changes to tracked files, and ANY untracked files.
+
+It will also cause all files inside the repository to be owned by root, and
+produce .whl files owned by root.
+
+Inside the root directory (i.e., one level above this python directory), run
+
+```
+docker run -ti --rm \
+    -e HOST_UID=$(id -u) \
+    -e HOST_GID=$(id -g) \
+    -e BUILDKITE_COMMIT="$(git rev-parse HEAD)" \
+    -e BUILD_ONE_PYTHON_ONLY=py39 \
+    -w /ray -v "$(pwd)":/ray \
+    -e HOME=/tmp \
+    quay.io/pypa/manylinux2014_x86_64:2026.01.02-1 \
+    /ray/python/build-wheel-manylinux2014.sh
+```
+
+The Python 3.9 wheel files will be placed in the `.whl` directory.
+
+One can change the value of `BUILDKITE_COMMIT` to generate wheels with
+different built-in commit string (the code is not changed) and
+`BUILD_ONE_PYTHON_ONLY` to build wheels of different Python versions.
+
+For arm64 / aarch64 architecture, use the `quay.io/pypa/manylinux2014_aarch64`
+image:
+
+```
+docker run -ti --rm \
+    -e BUILDKITE_COMMIT="$(git rev-parse HEAD)" \
+    -e BUILD_ONE_PYTHON_ONLY=py39 \
+    -w /ray -v "$(pwd)":/ray \
+    quay.io/pypa/manylinux2014_aarch64:2026.01.02-1 \
+    /ray/python/build-wheel-manylinux2014.sh
+```
+
+## Building MacOS wheels
+
+To build wheels for MacOS, run the following inside the root directory (i.e.,
+one level above this python directory).
+
+```
+./python/build-wheel-macos.sh
+```
+
+The script uses `sudo` multiple times, so you may need to type in a password.
