 Delta Lake server is a single socket Cooper Lake Scalable Processor (CPX-SP) server.
+Intel Cooper Lake Scalable Processor was launched in Q2 2020.
 
 Yosemite-V3 has multiple configurations. Depending on configurations, it may

 The Yosemite-V3 system is in mass production. Facebook, Intel and partners
 jointly develop Open System Firmware (OSF) solution on Delta Lake as an alternative
 solution. The OSF solution is based on FSP/coreboot/LinuxBoot stack. The
-OSF solution reached DVT exit equivalent status.
+OSF solution reached production quality for some use cases in July, 2021.
 
-## Required blobs
+## How to build
 
-Delta Lake server OSF solution requires:
+OSF code base is public at
+https://github.com/opencomputeproject/OpenSystemFirmware
+
+Run following commands to build Delta Lake OSF image from scratch:
+    git clone https://github.com/opencomputeproject/OpenSystemFirmware.git
+    cd OpenSystemFirmware/Wiwynn/deltalake && ./download_and_build.sh
+
+The Delta Lake OSF code base leverages [osf-builder] to sync down coreboot,
+Linux kernel and u-root code from their upstream repo, and sync down needed
+binary blobs. [osf-builder] also provides the top level build system.
