 ## Building the FPGA bitstream
 - install Vivado (known to work with 2020.1, known NOT to work with 2024.1)
-- install the package from your board in Vivado (Tools -> Vivado Store -> Boards)
-- start Vivado and open the project file **tridoracpu.xpr** in the **tridoracpu**)
+- install the package for your board in Vivado (Tools -> Vivado Store -> Boards)
+- start Vivado and open the project file **tridoracpu.xpr** in the **tridoracpu** directory
 - run synthesis, implementation and bitstream generation (Flow -> Generate Bitstream)
 - program your device (Flow -> Open Hardware Manager), the bitstream file should be in **tridoracpu/tridoracpu.runs/impl_1**
 - the bitstream file for (temporarily) programming your device is named **top.bit**, the file for flashing your device is named **top.bin**
