It's time to solve the second layer today. I'm sure you've all waited this moment and that you're damn excited about it. Good thing, because I am as well! The good news is that this step is by far the easiest in the method that we use. To put in a nutshell, you just have to remind one algorithm, reflect a little, and you're done. But enough of talking, let's start!
Reminder: Last time, we had stopped with our first layer solved, like this:
Today's step is about putting the four equatorial layer pieces in the right place, like this:
The first thing I advise you to do is to turn the cube upside-down (white face down, yellow up) so you can see what you're doing.
TIP: Try to get used to this, because in advanced methods, everything is solved with the white face below. This means that we even solve the first face without looking at it!
Now it's simple: The edges you want to locate are whether on the last layer (the unsolved one), or on the second layer but misplaced. In both cases, you will have to apply an algorithm. This one is going to take an edge from the last layer, and to put it in the second layer. The algorithm is U' L' U L U F U' F', and his symmetrical twin U R U' R' U' F' U F.
1) Easy case, the edge is on the third layer
Watch attentively which edge you have to locate! Here is a tip: the edges with yellow are not to be located in this step, because they belong to the third layer. Focus only on following edges: orange-blue, blue-red, red-green, and green-orange. Now turn the last layer until you shape a reversed "T" with the face in front of you (here orange).
U' L' U L U F U' F'
U R U' R' U' F' U F
TIP: As the two algorithms are exactly symmetrical, they are easy and quick to learn!
2) Annoying cases, the edge is located in the right place but misguided, or misplaced in the second layer

Focus only on following edges: orange-blue, blue-red, red-green, and green-orange. Now turn the last layer until you shape a reversed "T" with the face in front of you (here orange).
CASE 1: The edge has to go down left. Usually a F' rotation would be enough, but you would destroy your white face! The alternative:
U' L' U L U F U' F'
CASE 2: The edge has to go down right. F rotation should be enough, but it would also destroy your white face! The alternative:
U R U' R' U' F' U F
TIP: As the two algorithms are exactly symmetrical, they are easy and quick to learn!
2) Annoying cases, the edge is located in the right place but misguided, or misplaced in the second layer
OR
In this case, you just have to use your brain! You just saw that the algorithm above enables you to put an edge from the last layer to the second layer.
Therefore, you just have to make the corresponding algorithm, to put an edge "lambda" in place of the edge you want to locate. Then, your edge will be released on the last layer and you will find yourself in an easy case again!
TIP: Try to be as efficient as possible in order to save time: If you have to release an edge like in the case above, use the yellow edges, because they aren't important in this step. (Yellow edge = edge with yellow and any other color) For instance in the last picture above, if you use the green-red edge to release the orange-green edge, your green-red edge will be stuck and you will have to release it later with another edge. Whereas if you use a yellow edge, it's fine because you still have your green-red edge on the top, waiting to be put in. Or better, use directly the red-blue edge if it's available!
If you have carefully followed my instructions, your second layer should be over. If you managed to do it, I congratulate you. Only the last layer remaining, and you will have finished your Rubik's Cube!
