+## Building
+
+A C compiler and Intel(R) OneAPI Math Kernel Library (OneMKL) are required to build mkl-service from source.
+
+Executing
+```sh
+python -m pip install .
+```
+
+will pull in the required build and runtime dependencies, including `mkl`, and build `mkl-service`.
+
+With an existing system or Conda `mkl` installation, build dependencies
+- `mkl-devel`
+- `meson-python`
+- `cmake`
+- `ninja`
+- `cython`
+
+then, simply execute
+```
+python -m pip install --no-build-isolation --no-deps .
+```
