Update README for drivers

This README tends to get out of date and it's better to have just one
source of truth.

 This repository contains instructions and source code to build, package and run
 Fuchsia samples using only the Fuchsia SDK.
 
-## Requirements
-
-1. Make sure this repository has the required submodules:
-
-   ```
-   git submodule update --recursive --init
-   ```
-
-1. Run the bootstrap script that downloads the appropriate Bazel binary:
-
-   ```
-   scripts/bootstrap.sh
-   ```
-
-1. Ensure that there are Fuchsia SSH keys in your host machine. You will need
-   them for running the Fuchsia emulator.
-
-   ```
-    [[ -f "${HOME}/.ssh/fuchsia_ed25519" ]] || ssh-keygen -P "" -t ed25519 -f "${HOME}/.ssh/fuchsia_ed25519" -C "${USER}@$(hostname -f) Shared SSH Key for Fuchsia"
-
-    [[ -f "${HOME}/.ssh/fuchsia_authorized_keys" ]] || ssh-keygen -y -f "${HOME}/.ssh/fuchsia_ed25519" > "${HOME}/.ssh/fuchsia_authorized_keys"
-   ```
-
-## Build, run and test the samples
-
-The repository is ready to build the samples.
-
- > Note: in order to use an SDK produced by a local Fuchsia platform tree, you
- > can set an environment variable named `LOCAL_FUCHSIA_PLATFORM_BUILD` as
- > described in https://fuchsia.googlesource.com/sdk-integration/+/0503b02c059a6de76242280b467898358ba30ae3
-
-1. If using an emmulator:
-
-   1. Fetch the system images
-
-      ```
-      tools/ffx product-bundle get workstation_eng.qemu-x64 --repository workstation-packages
-      ```
-
-   > Note: if the command above fails with an error message that
-   > states that there are multiple product bundles with the same name, you can either specify
-   > the full qualified URL as printed in the error message, or you can wipe out
-   > old and unused product bundles in the pbms storage, which should be located
-   > in ~/.local/share/Fuchsia/ffx/pbms on Linux, or ~/Library/Fuchsia/ffx/pbms
-   > on MacOS.
-
-
-   1. Start the emulator
-
-      ```
-      tools/ffx emu start workstation_eng.qemu-x64 --headless \
-         --kernel-args "driver_manager.use_driver_framework_v2=true" \
-         --kernel-args "driver_manager.root-driver=fuchsia-boot:///#meta/platform-bus.cm" \
-         --kernel-args "devmgr.enable-ephemeral=true"
-      ```
-
-   1. The product bundle comes with on-demand packages in a separate repository.
-      Use the following command to register it with the emulator:
-
-      ```
-      tools/ffx target repository register -r workstation-packages --alias fuchsia.com --alias chromium.org
-      ```
-
-1. If using a physical device like a Pixelbook Go:
-
-   1. Fetch the system images
-
-      ```
-      tools/ffx product-bundle get workstation_eng.qemu-x64-dfv2 --repository workstation-packages
-      ```
-
-   1. Prepare and connect the Pixelbook Go, by flashing and/or paving it (not
-      covered here), and connect using Ethernet.
-
-   1. The product bundle comes with on-demand packages in a separate repository.
-      Use the following command to register it with the device:
-
-      ```
-      tools/ffx target repository register -r workstation.qemu-x64-dfv2 --alias fuchsia.com --alias chromium.org
-      ```
-
-   1. Update (OTA) the device to the version of the SDK:
-
-      ```
-      tools/ffx target update check-now --monitor
-      ```
-
-1. (optional) watch the device log in a separate window
-
-   ```
-   tools/ffx log
-   ```
-
-1. Load the sample drivers
-
-   Now you are ready to register a driver. Starting with the [example driver](src/example_driver):
-
-   First, let's confirm that the driver is not loaded:
-
-   ```
-   tools/ffx driver list | grep example_driver
-   ```
-
-   The command above should not return any driver named "example_driver" because
-   it has not been registered.
-
-   Now register the driver:
-
-   ```
-   tools/bazel run --config=fuchsia_x64 src/example_driver:pkg.component
-   ```
-
-   The driver now should show in the list of loaded drivers:
-   ```
-   tools/ffx driver list | grep example_driver
-   fuchsia-pkg://bazel.pkg.component/example_driver#meta/example_driver.cm
-   ```
-
-   You can also watch in the log to see if the driver is loaded correctly. The ffx log
-   window should show a message similar to:
-
-   ```
-   [88.961][bootstrap/driver_manager][driver_manager.cm][I] Loaded driver 'fuchsia-pkg://bazel.pkg.component/example_driver#meta/example_driver.cm'
-   ```
