 Welcome to the home of MFC!
 MFC simulates compressible multi-component and multi-phase flows, [amongst other things](#what-else-can-this-thing-do). 
-It scales <b>ideally to exascale</b>; [tens of thousands of GPUs on NVIDIA- and AMD-GPU machines](#is-this-really-exascale) on Oak Ridge Summit and Frontier.
 MFC is written in Fortran and makes use of metaprogramming to keep the code short (about 20K lines).

 We'll give a brief intro. here for MacOS.
 Using [brew](https://brew.sh), install MFC's modest set of dependencies:
 ```shell
-brew install wget python cmake gcc@13 mpich
+brew install wget python cmake gcc@14 mpich
 ```
 You're now ready to build and test MFC!
 Put it to a convenient directory via
 ```shell
-git clone https://github.com/MFlowCode/MFC.git
+git clone https://github.com/MFlowCode/MFC
 cd MFC
 ```
 and be sure MFC knows what compilers to use by appending and sourcing your `~/.profile` file via this command
 ```shell
-echo -e "export CC=gcc-13 \nexport CXX=g++-13 \nexport FC=gfortran-13" >> ~/.profile
+echo -e "export CC=gcc-14 \nexport CXX=g++-14 \nexport FC=gfortran-14" >> ~/.profile
 source ~/.profile
 ```
 then you can build MFC and run the test suite!

 [OLCF Frontier](https://www.olcf.ornl.gov/frontier/) is the first exascale supercomputer.
 The weak scaling of MFC on this machine is below, showing near-ideal utilization.
