+# Bcachefs is up!
+
+It's still alpha quality, but the code is up and you can play with it now. Build
+a kernel from the bcache-dev branch, and a new bcache-tools from the dev branch
+in that repository.
+
+Then, just run
+
+    bcacheadm format -C /dev/sda1
+    mount /dev/sda1 /mnt
+
+It's fast - many years of performance improvements since what's in the upstream
+kernel, and a long list of features - among them, multiple devices and full data
+checksumming/compression.
+
+Be warned - the on disk format has not been frozen yet, and it might eat all
+your data (but it is passing all but a few of the tests in xfstests).
