 An open source distribution of firmware utilizing coreboot, EDK2, and System76
 firmware applications.
 
-## Supported models and features
+## Resources
 
-To view models that are supported and will receive updates through the firmware
-manager, as well as available features for those models, please see the
-[feature matrix](./FEATURES.md).
-
-Other models may be in development or available without support, and can be
-seen in the `models/` directory.
-
-If the device becomes bricked it will require restoring the current firmware
-using an external programmer. See [flashing](./docs/flashing.md) for details.
-
-### Schematics
-
-System76 customers may request board schematics for their system by sending an
-email to firmware@system76.com with the subject line  "Schematics for _model_",
-where _model_ is one of the supported models listed above. Please include the
-serial number of your system for verification.
-
-You may not share these without explicit permission from System76.
-
-## Changelog
-
-For a list of important changes please see the [changelog](./CHANGELOG.md).
-
-## Building
-
-Dependencies can be installed with the provided script.
-
-```sh
-./scripts/install-deps.sh
-```
-
-If rustup was installed for the first time, it will be required to source the
-environment file it installed to use the correct Rust toolchain.
-
-```
-source ~/.cargo/env
-```
-
-A script is provided to build the firmware. The available targets for building
-are the model folders in `models/`. For example, to build for QEMU:
-
-```
-./scripts/build.sh qemu
-```
-
-Once built, the firmware must be flashed to use. Several scripts are available
-to flash the new firmware, depending on how it is going to be written.
-
-- `scripts/qemu.sh`: [Run the firmware in QEMU](./docs/debugging.md#using-qemu) (specific to the QEMU model)
-- `scripts/flash.sh`: Flash using the internal flasher
-- `scripts/ch341a-flash.sh`: Flash using a CH341A programmer
-- `scripts/spipi-flash.sh`: Flash using a Raspberry Pi
-
-See [Flashing firmware](./docs/flashing.md) for more details.
