requirement for nasm is not documented in README about python-isal HOT 1 CLOSED

Quoting the readme:

Installation is supported on Linux, Windows and MacOS. For more advanced installation options check the documentation.

Quoting the documentation:

Installation is supported on Linux, MacOS and Windows. On most platforms wheels are provided. The installation will include a staticallly linked version of ISA-L. If a wheel is not provided for your system the installation will build ISA-L first in a temporary directory. Please check the ISA-L homepage for the build requirements.

Emphasis mine

Quoting the isa-L homepage:

Building ISA-L
Prerequisites

    Make: GNU 'make' or 'nmake' (Windows).
    Optional: Building with autotools requires autoconf/automake/libtool packages.
    Optional: Manual generation requires help2man package.

x86_64:

    Assembler: nasm. Version 2.15 or later suggested (other versions of nasm and yasm may build but with limited function [support](https://github.com/intel/isa-l/blob/master/doc/build.md)).
    Compiler: gcc, clang, icc or VC compiler.

aarch64:

    Assembler: gas v2.24 or later.
    Compiler: gcc v4.7 or later.

other:

    Compiler: Portable base functions are available that build with most C compilers.

So it is mentioned. Yes, you have to dig a little. Since most of the users can use a prebuilt wheel, I think it is justified not having this on the front page.
