 ## Drag & Drop Programming
 
 To program the Sonata bitstream:
 
-1. Download the bitstream from [our releases](https://github.com/lowRISC/sonata-system/releases)
+1. Download the bitstream from [our releases](https://github.com/lowRISC/sonata-system/releases).
 2. Make sure that you have the bitstream switch (SW3) set to 1.
 3. Plug in your Sonata board using the main USB. You should see a 'SONATA' drive (see troubleshooting section if unsure).
 4. Copy the updated FPGA `sonata-vX.Y.bit.slot1.uf2` file to the drive and wait for the copy to complete (on Linux note the copy command may return immediately, so you need to wait until it's done.)
