Merge #176

176: small update to instructions in README r=jrvanwhy a=JOE1994

I initially misunderstood the README directions and thought that simply running
```make hail``` would build all examples in this repo and flash them to my device.
(#175 )

Although it was on part my bad for misunderstanding the README , 
I made a small update to make the directions a bit more clear.

Please feel free to close this PR if you feel this change is unnecessary.
Thank you for reviewing this PR :+1:

Place the layout definition file at `boards/layout_<platform>.ld` and do not forget to enhance the `tockloader_flags` dispatching section in `tools/flash.sh`. You are welcome to create a PR, s.t. the number of supported platforms grows.
