This is the general principle of CPFP, and it may not be entirely correct.

Step 1: Find the txid of your unconfirmed transaction
Step 2: Calculate the fee for the unconfirmed transaction with a fee of 0.0001 BTC/Kb
Step 3: Create a transaction that spends the unconfirmed transaction to another Bitcoin address. Include in its fee the recommended fee and the fee you calculated in step 2. (e.g. fee of 0.0001 BTC for both transactions means 0.0002 BTC fee in this new one)
Step 4: Sign the new transaction.
Step 5: Push the transaction to the network. It is recommended to use http://eligius.st/~wizkid057/newstats/pushtxn.php because the mining pool Eligius is one of the only pools to implement CPFP. This will push straight to them and the rest of the network.
Step 6: Wait for someone, probably Eligius, to mine a block and include both of your transactions. This could take a couple hours since Eligius has a small percentage of the hashrate of the network.

Congrats! You now have two confirmed transactions
