Perhaps a troubleshooting section in the README?
Hi!
I've read through a bunch of the other issues (there seems to be a lot, comparatively ) regarding the example code in the readme. Would it not be good if we had a bunch of troubleshooting tips?
Like: 
If your having trouble installing nimx, try doing the following before posting an issue:
`nimble install -y variant`
`nimble install -y https://github.com/yglukhov/ttf`
`nimble install nimsl`
