-This step can take a long time, but it will ensure that the toolchain will work
-with Limine. If on an x86_64 host, with GCC or Clang installed, it is possible
-that the host toolchain will suffice. You can skip to the next paragraph in order
-to use the system's toolchain instead. If that fails, you can still come back here
-later (remember to `make clean` and re-run `./configure` after building the toolchain).
-
-The toolchain's build process depends on the following packages: `GNU make`,
-`GNU tar`, `texinfo`, `curl`, `gzip`, `bzip2`, `gcc/clang`, `g++/clang++`.
-
-Building the toolchain can be accomplished by running:
-```bash
-TARGET=<target architecture> ./make_toolchain.sh
-```
-where `<target architecture>` is something like `i686` or `x86_64`.

 ### Prerequisites
 
 In order to build Limine, the following programs have to be installed:
 `GNU make`, `grep`, `sed`, `find`, `awk`, `gzip`, `nasm`, `mtools`
 (optional, necessary to build `limine-cd-efi.bin`).
