Snippet under "Getting Started" doesn't work

[AdamStelmaszczyk]

Snippet in https://github.com/smarkets/smk_python_sdk#getting-started is outdated.

Looks like:

• settings.host and/or settings.port was changed
• order.market is obsolete, one should use order.market_id instead, the same for order.contract
• order.time_in_force was renamed to order.tif
• BUY was renamed to SIDE_BUY

Expected behaviour:

After copy pasting it to Python REPL (with correct credentials, market_id and contract_id) it should login and place a bet.
