+SDPA for Python can be installed for `x86_64` through `pip`. Two variants of this package are available on the Python Package Index (PyPI). The package using the SDPA (OpenBLAS) backend can be installed by
 
 ```bash
 pip install sdpa-python
 ```
 
+The package using the SDPA Multiprecision (GMP) backend can be installed by
+
+```bash
+pip install sdpa-multiprecision
