+## Why a Libre 3D CPU / GPU / VPU?
+
+* Study of SoCs (Allwinner, Rockchip, NXP) shows none are fully Libre
+  - Either GPU driver firmware is proprietary, or VPU firmware, or bootloader
+* This causes customer product development issues
+  - https://tinyurl.com/valve-steam-intel
+* Businesses are waking up to lack of transparency
+  - Intel Management Engine (spying backdoor co-processor)
+  - Spectre, Meltdown, CSME (Chain-of-Trust) issues
+* Solution: full transparency.  All source available for everything.
+
+## How is LibreSOC being developed?
+
+* Using Libre (rather than "open") development practices
+  - no "I'll release it when it's ready": all development is real-time public access
+* No NDAs, no hidden discussions
+  - we can invite anyone (any expert) to help with review
+  - free to ask for help anywhere in the world (comp.arch, stackexchange)
+* Using litex, nmigen, opencores HDL
+  - heavily depending on python OO (not possible with VHDL or Verilog)
+  - leap-frogging ahead by not reinventing the wheel
+
+## What is being developed? Roadmap
+
+* First simple core achieved in simulation Sep 2020
+  - FPGA (ECP5) target followed shortly
+* First silicon tape-out 180nm deadline 2nd Dec 2020
+  - sponsored by NLnet, with help from Chips4Makers Libre Cell Libraries
+  - layout is entirely libre-licensed tools: coriolis2 from lip6.fr
+* Next chip is "SBC" style quad-core
+  - similar spec to Allwinner A64, Rockchip RK3399
+  - targets "Pi" boards, smartphones, tablets, Industrial IoT
