The whole game in Dota 2 is built around killing creeps, which are of two types: lane and neutral. Linear go on the lines, with a periodicity of 30 seconds, and neutral are on forest spots, and appear once a minute. Creeps are very important because for killing them you get gold, which is needed to buy items, and experience, which is needed to level up, learn abilities and talents.
You can do a lot of manipulations with creeps, and they are not limited to killing them. I suggest you look at all these possibilities in more detail, and understand how to use them.

How to kill creeps?

In order to get gold for creeps, you need to kill them personally, that is, you need to strike the last blow on the creep. You need to learn how to do this, so you should practice it in the lobby. You also need to be able to feel the attack of your hero to understand at what moment to attack to finish the creep. By default, PCM is used for attacking.

How do I kill my creeps?

This is also a very important aspect. Denai your creeps, prevents the enemy from getting gold from them, and cuts experience by half. If you denai well, you can dominate a line by kicking the enemy hero out of it, and surpassing him in experience. This is done in the same way as with a normal kill, but is only available after the creep has less than half XP.

How to herd creeps? 

It is important to learn how to do this, because such stacks will help you get a large amount of gold in a short period of time. To make them you need, depending on the type of neutral camp, take out of there creeps, about 53-55 seconds. When the creeps leave a certain radius, new ones will appear on the spot. This way you can get a huge amount of creeps and then you can farm them all at once.

How to divert creeps. 

Diversions will always help you to put the line evenly, so that it was more comfortable to stand. They are done quite simply by hitting a neutral creep and leading it towards your line. Then the allied creeps that pass by will attack him and change their route.
