+The sole purpose of Program.cs is to fire `InitAsync()` in Coc.cs, Sql/Db.cs and Discord.cs, then wait forever.
 
 Discord.cs requires some time to be 'ready'. When it's ready, it calls `Coc.BotReadyAsync`, which is an endless loop that processes Coc.cs tasks every 5 seconds.
 
 ## Coc.cs
 When Discord bot is ready, Coc.cs fetches the first copy of clan data. `PollAsync` is called every 5s.
 
-For each call, it fetches the latest Clan data and compares it with the previous one. The result is stored in a `ClanUtil` and is used to dispatch other tasks within Coc.cs. When all the tasks are done, it will replace the previous clan data with the current one.

 # Coding Guidelines
 
 1. No variables should be shared between `Discord.cs`, `Coc.cs` and `Db.cs`. If you need functionalities in another module, expose a public method and call it instead.
-2. Access modifiers: If a var/func shouldn't be shared, make it private. If a var/func should be shared, make it public.
