-From time to time, Apple Silicon DDEV users encounter an image or a Node.js package that is not available for the Mac's native architecture (variously called ARM64 or `aarch64`). These result in errors like: "Could not open '/lib64/ld-linux-x86-64.so.2': No such file or directory".
+From time to time, Apple Silicon DDEV users encounter an image or a Node.js package that is not available for the Mac's native architecture (variously called ARM64 or `aarch64`). These result in errors like: "Could not open '/lib64/ld-linux-x86-64.so.2': No such file or directory" or "the chromium binary is not available for ARM64".
 
 Emulation of Docker images has been pretty scary and unreliable since the Apple Silicon macs came out, but there is some hope. 
 
 To be clear: If you do not absolutely have to have a project that can run AMD64 Docker images or applications, don't do any of this. I always recommend running native ARM64 Docker images and applications on Apple Silicon Macs. Your life will be bettter. 
 
 But if you have to run something like the `puppeteer` or `node-sass` Node.js packages, which are only available for AMD64, you might be able to do it. I'm going to show three ways that might work for you. You may have to try all of them, and I'll be really interested in your results.
 
+## Prerequisite: Enable Rosetta
+
+To use these techniques, you *must* enable Apple's virtualization layer, Rosetta. Their [tech article](https://support.apple.com/en-us/102527) explains how. It's easy.

 ## 1. Use [OrbStack](https://orbstack.dev) with the `DOCKER_DEFAULT_PLATFORM=linux/amd64`
 
-OrbStack is a great new Docker provider; super lightweight and performant, and it does [nice emulation](https://docs.orbstack.dev/docker/#intel-x86-emulation) using your Mac's Rosetta system.

 This was the easiest to use and most performant of the options.
 
 ## 2. Use [Docker Desktop for Mac](https://www.docker.com/products/docker-desktop/) with the `DOCKER_DEFAULT_PLATFORM=linux/amd64`
 
 This is about the same, but you have to toggle some non-default settings. 
 
-First, in the Docker Desktop UI under "Features in Development", enable "Use Rosetta for `x86/amd64` emulation on Apple Silicon". Obviously you have to have Rosetta enabled for this to work, and Docker Desktop may impose other requirements. This probably only works on Ventura and higher.
+You **must** enable "Use Rosetta for `x86_64/amd64` emulation on Apple Silicon" in the "General" section of Docker Desktop's settings. This is well down the list of checkboxes, you have to scroll to get down there.

 You can actually have all these running at the same time, although it doesn't make any sense to do so. Each has a separate Docker context and you can switch between them using the `docker context` command. For example, `docker context use colima-amd64` will use the AMD64 Colima profile we created. `docker context use orbstack` will switch to OrbStack. And `docker context use desktop-linux` will switch to Docker Desktop. Use `docker context ls` to see what's set up on your system.
 
+They won't be happy sharing ports though, so you'll want to change `router_http_port`, `router_https_port`, `mailpit_http_port`, and `mailpit_https_port` between the various providers (and between ARM64 and AMD64 instances).
