 # Cross-build Container for Building the Linux Executables for this zrok Project
 
-Running this container produces three executables for zrok, one for each platform architecture: amd64, arm, arm64. You may specify the target CPU architecture as a parameter to the `docker run` command.
+Running this container produces one snapshot executable for zrok from the current checkout, even if dirty. Platform choices are: `amd64`, `arm64`, `arm` (the arm/v7 "armhf" ABI target), and `armel` (the arm/v7 "armel" ABI). You may specify the target architecture as a parameter to the `docker run` command.
 
 ## Build the Container Image
 
 You only need to build the container image once unless you change the Dockerfile or `./linux-build.sh`.
