+### Will OpenBMC run on my Acme Server Corp. XYZ5000 motherboard?
+
+This is a common question, particularly regarding boards from popular COTS
+(commercial off-the-shelf) vendors such as Supermicro and ASRock.  You can see
+the list of supported boards by running `. setup` (with no further arguments) in
+the root of the OpenBMC source tree.  Most of the platforms supported by OpenBMC
+are specialized servers operated by companies running large datacenters, but
+some more generic COTS servers are supported to varying degrees.
+
+If your motherboard is not listed in the output of `. setup` it is not currently
+supported.  Porting OpenBMC to a new platform is a non-trivial undertaking,
+ideally done with the assistance of schematics and other documentation from the
+manufacturer (it is not completely infeasible to take on a porting effort
+without documentation via reverse engineering, but it is considerably more
+difficult, and probably involves a greater risk of hardware damage).
+
+**However**, even if your motherboard is among those listed in the output of
+`. setup`, there are two significant caveats to bear in mind.  First, not all
+ports are equally mature -- some platforms are better supported than others, and
+functionality on some "supported" boards may be fairly limited.  Second, support
+for a motherboard is not the same as support for a complete system -- in
+particular, fan control is critically dependent on not just the motherboard but
+also the fans connected to it and the chassis that the board and fans are housed
+in, both of which can vary dramatically between systems using the same board
+model.  So while you may be able to compile and install an OpenBMC build on your
+system and get some basic functionality, rough edges (such as your cooling fans
+running continuously at full throttle) are likely.
