+## Motivation
+
+Python is commonly used in the fields of scientific computing, data analysis and
+machine learning. However, the Python packages used in these disciplines aren’t
+wholly written in Python - they also contain a lot of code written in C/C++ or
+other languages which needs to be built as part of the module. Such projects
+typically create binary wheels for each of their releases and upload these
+wheels to pypi, the Python Package Index. This allows users to easily and
+quickly install tested, prebuilt versions of their favourite projects using the
+pip (or [uv](https://docs.astral.sh/uv/)) tool.
+
+Until recently, Python packaging infrastructure like
+[auditwheel](https://github.com/pypa/auditwheel),
+[cibuildwheel](https://github.com/pypa/cibuildwheel), and
+[manylinux](https://github.com/pypa/manylinux) did not support riscv64, and no
+native runners for GitHub Actions were available. This made supporting the
+architecture difficult for open-source projects without complicated build
+processes and emulated systems. However, the aforementioned infrastructure now
+supports riscv64, and with the RISE [RISC-V
+Runners](https://riscv-runners.riseproject.dev/) project, maintainers have the
+option of building binary wheels on native riscv64 platforms. The RISE Python
+Wheels project's goal is to accelerate this adoption and ensure that the riscv64
+architecture is fully-supported for data science and machine learning
+applications.
