In order to use haskello you need to pass API
key and token as environment variables. Key and
token may be obtained from official Trello
website: https://trello.com/app-key.
haskello expects that TRELLO_KEY and
TRELLO_TOKEN are both present in environment at
runtime.
For example:
TRELLO_TOKEN=mySecretToken TRELLO_KEY=mySecretKey haskello

Main idea is to store server state in LocalTrello datatype and changes
of state in Changelist. This way all changes are tracked and separated
from main storage.
Every view presents screen with related items (eg. list of boards or list of cards).
Screen is created on enter from LocalTrello storage type and Changelist.
Edited items are populated to Changelist and screen. Changelist is also used
as source of truth for server sync.
