We are preparing information packs at present to make this super straightforward.
These will appear on the website soon.

But for the keen supporters: you do not have to wait!  
Here are some tools:

There are many videos you can choose from on our videos page to show to an audience
or living-room gathering.

Flyers & downloads
Flyers (A5 double sided) and placards/banners (A3 double sided) are ready to download
as print-ready PDFs and send to your chosen printer. 

Do let us know if you're heading to a major event (eg a festival) and are taking
or want to take flyers with you - we may have a stall or speaking slot you can help at.

Go for it!  
We're also happy to be contacted with your specific questions.
