 First, head to the [Sonata System Release Page](https://github.com/lowRISC/sonata-system/releases/) where you'll find the latest releases.
 Each release includes an RP2040 firmware image and FPGA bitstream. Once you have downloaded these, proceed with the following tasks:
 
-1. [Program the RP2040 With the latest](rp2040-update.md) firmware to get any bug fixes by entering bootloader mode & dragging the `rpi_rp2_v0.XX.uf2`.
-2. [Get the latest FPGA image](fpga-update.md) that corresponds with the software you are building. This requires you to just drag the new `sonata_vXX.bit.slot1.uf2` file into the 'SONATA' drive that comes up when you plug in the board to your computer.
