+\\=====================================/
+
+Uh oh! We couldn't find either curl or wget installed on your system.
+
+To continue with installation, you have two options:
+
+A. Install either wget or curl on your system. You may need to run `hash -r`.
+
+B. Define GETMICRO_HTTP to be a command (with arguments deliminated by spaces)
+    that both follows HTTP redirects AND prints the fetched content to stdout.
+
+For examples of option B, this script uses the below values for wget and curl:
+
+  $ curl https://wakapi.dev/get | GETMICRO_HTTP="curl -L" sh
+
+  $ wget -O- https://wakapi.dev/get | GETMICRO_HTTP="wget -O-" sh

 Uh oh! We couldn't automatically detect your operating system. You can file a
 bug here: https://github.com/muety/wakapi
+
+To continue with installation, please choose from one of the following values:
+
+- win_amd64
+- darwin_amd64
+- linux_amd64
+
+Export your selection as the GETWAKAPI_PLATFORM environment variable, and then
+re-run this script.
+
+For example:
+
+  $ curl https://getmic.ro | GETWAKAPI_PLATFORM=linux_amd64 sh
+
 EOM
   exit 1
