+The library requires NASM to be built. Depending on the library version, it might
+require a minimum NASM version (e.g. v0.54 requires at least NASM 2.14).

+NASM is packaged for different OS. However, on some OS the version is too old,
+so a manual installation is required. In that case, NASM can be downloaded from
+`NASM website <https://www.nasm.us/pub/nasm/releasebuilds/?C=M;O=D>`_.
+Once it is downloaded, extract it and follow these steps:

+   Compilation of the Multi-Buffer library is broken when GCC < 5.0, if library <= v0.53.
