 # agnos-builder
 
-This is the tool to build AGNOS, our Ubuntu based OS. AGNOS runs on the [comma three devkit](https://comma.ai/shop/products/three).
+This is the buidler repo for AGNOS, our Ubuntu based OS. AGNOS runs on the comma three devkit and [comma 3X](https://comma.ai/shop/comma-3x).
 
 NOTE: the `edk2_tici` and `agnos-firmware` submodules are internal, private repos.
 
-## Setup
+## Development
 
 These tools are developed on and targeted for Ubuntu 20.04.
 
 Run once to set things up:
 ```sh
+cd ~
+git clone https://github.com/commaai/agnos-builder.git
+
+cd agnos-builder
 git submodule update --init agnos-kernel-sdm845
 ./tools/extract_tools.sh
 ```
 
-## Build the userspace

-build:
-```sh

+./build_kernel.sh
 ./build_system.sh
 ```
 
-load:
-```sh
+Flashing to a comma 3/3X:
+```
+./flash_kernel.sh

+A comma 3/3X is helpful for working on AGNOS, but there's still lots of interesting work to do without one.

+### Roadmap
+
+AGNOS's main priority is to provide a stable platform to [openpilot](https://github.com/commaai/openpilot).
+The second priority is to be a good platform for all sorts of [robotics development](https://blog.comma.ai/a-drive-in-the-office/).
+
+Now that AGNOS is good at running openpilot, the next things up are:
+* speedups: build system, CI, boot time, etc.
+* cleanups: Android kernel to mainline kernel
+* open source: AGNOS started with a bunch blobs for various things, like the bootloaders and weston. We want to move everything we can to open source versions built in this repo.
+
+Some concrete things on the roadmap:
+- [ ] <10s boot time https://github.com/commaai/agnos-builder/issues/110, https://github.com/commaai/openpilot/issues/30894
+- [ ] make the image tiny, for fast updating and flashing https://github.com/commaai/agnos-builder/issues/225
+- [ ] update to Ubuntu 24.04 https://github.com/commaai/openpilot/issues/32386
+- [ ] mainline Linux kernel https://github.com/commaai/openpilot/issues/32386
+- [ ] fully open source 
+  - [ ] anything from `agnos-firmware`: XBL, ABL, etc.
+  - [ ] open source Weston https://github.com/commaai/agnos-builder/issues/16
