+*** WARNING: THIS IS A DESTRUCTIVE TESTING TOOL ***
+
+devsoak deliberately overwrites every sector in the range you point it at,
+issues edge-case and malformed commands, and drives a driver to its
+limits for hours at a time. It is built for developers and testers who
+understand block device internals and have deliberately chosen a sector
+range, partition, or whole device they do not mind losing. Point it at
+the wrong unit number and it WILL destroy live data - there is no
+confirmation beyond the -y flag you pass it yourself, and no undo.
+
+If you are not comfortable identifying your target device's unit number
+with certainty, back up first, or do not run this tool.

 devsoak is a destructive correctness and soak tester for trackdisk-style
 AmigaOS block device drivers. One run answers two questions: does every
 command the driver accepts do the right thing - including the edge cases

 Requirements
 ------------
-  - AmigaOS 3.0+ (KS 1.3 is also supported at reduced dialect coverage)
-    or AROS m68k, 68000 or better.
+  - AmigaOS, Kickstart 1.3 or later, or AROS m68k, 68000 or better.
+    devsoak probes the driver under test at startup and exercises
+    whichever command dialects (CMD/ETD/TD64/NSD/NSD-ETD) it actually
+    advertises - so a 1.3-era driver simply advertises fewer dialects
+    itself, rather than devsoak testing less on 1.3.
   - A block device to test, and a sector range on it you do not need.
