+
+    In a project based on a TT template, with a configured info.yaml, all you need
+    is to run
+
+      python tt/tt_fpga.py harden
+
+    to generate a bitstream in build/.  Then
+
+      python tt/tt_fpga.py configure --upload
+
+    will make the bitstream available through the tt.shuttle object in the DB REPL.
+
+    You may also set this as the default project to load on startup and/or set the
+    auto-clocking rate through the configure command, e.g.
+
+      python tt/tt_fpga.py configure --upload --set-default --clockrate 1000
+
+    to do all three at once.
+
+
+    If you have no info.yaml template, the script will work anyway.  But you'll need
+    to specify more command line arguments.
+
+    See
+        python tt/tt_fpga.py harden --help
