 ## `nasm`
 
-`nasm` is an assembler specifically tailored for the NES/Famicom. Build it and
-run it with cargo, or you can install it somewhere in your `$PATH` and simply:
-
-```
-$ nasm awesome.s
-```
-
-This will produce an `out.nes` file placed under the same working directory. You
-can change the name of the file with the `-o/--output` flag. Hence, you can call
-it like so:
-
-```
-$ nasm -o awesome.nes awesome.s
-```
-
-Moreover, you can actually tell `nasm` to redirect the output to stdout instead
-with the `--stdout` flag. This is useful when debugging the binary format with
-another CLI tool. For example:
-
-```
-$ nasm --stdout awesome.s | hexdump -C
-```
-
-By default it will assume the configuration for an `NROM` mapper, but this can
-be changed with the `-c/--configuration` flag, which accepts the following
-values: `empty`, `nrom`, `nrom65`, `unrom`, `uxrom` and `mmc1`. These values
-correspond to the configurations [already bundled](./lib/xixanta/src/mappings)
-on this application, which follow a simplified syntax from the
-[ld65](https://www.cc65.org/doc/ld65-5.html) one. Alternatively, you can also
-pass the path to a configuration file to this flag. This file can either follow
-the same [ld65](https://www.cc65.org/doc/ld65-5.html) syntax, or the simplified
-one.
