Mining is the method used to generate digitalcoin. Miners use GPUs(Graphical Processing Units) or CPUs(Central Processing Units) to process digitalcoin transactions by hashing. Finding a solution to a block rewards the miner who found it so that they have an incentive to process transactions.
A pool is a collective of miners working together to solve blocks and sharing the rewards. This has the effect of lowering the randomness in mining.
To connect to a pool, use any Scrypt mining software and point it at a digitalcoin pool.
Example: cgminer.exe –scrypt -I 11 -s 1 –expiry 1 –queue 0 -g 1 -o EXAMPLEPOOL.COM -u username -p worker.password
Pools will often post optimal settings so make sure to check those.
