 Building It
 -----------
 
 If you want to build a board right now, there are two possible routes:
- - Use the current master-branch PCB (`hardware/epaper-breakout/gerbers`), contributed by @sebastius.
-   They, offer some improvements over the original v2 PCB, as described here: https://github.com/vroland/epdiy/issues/3.
-   Although this version *should* work, it was not physically built yet. (if you did, please contact me!)
+ - Use the new v2 PCB (`hardware/epaper-breakout/gerbers_v4.zip`). This is a bit more fresh, but should work.
+   The BOM is available at (`hardware/epaper-breakout/BOM.csv`).
+   Positioning files for SMT assembly are available at (`hardware/epaper-breakout/gerbers/epaper-breakout-top-pos.csv`). 
+   Please double check the part positioning and Rotation with your assembly service!
+
+   Make sure to select the `V4` board revision in `idf.py menuconfig` when building the examples.
  - Use the original v2 PCB (`hardware/epaper-breakout/gerbers_v2_rev0.zip`). 
    However, you might run into issue #3 with some selections of parts.
+
+   Make sure to select the `v2/v3` board revision in `idf.py menuconfig` when building the examples.
