Few days ago I installed MySQL and MediaWiki on my virtual server, so I could write a wiki to document all the API changes I have made to Talleo. It currently contains all RPC methods used by node daemon (Talleod) and wallet daemon (walletd).
I'm planning to later add documentation also for official webwallet and other services that third-party developers might want to utilize.
The wiki will also include documentation for common data structures used by the RPC methods and explanations for some of the more technical terms.
Until everything is finished, the wiki will be read-only for unregistered users and user accounts can't be created by visitors.
