1º Step
We will download Hydra from GitHub is the official source where the creator has it uploaded, it would be the version hydralauncher-3.4.0-setup.exe, there is also portable. 

(https://github.com/hydralauncher/hydra/releases/download/v3.4.0/hydralauncher-3.4.0-setup.exe)

2nd Step
After installing it we must go to application settings and download sources. This is like a kind of torrent links from which the games will be downloaded, most of them are reliable sources and each one brings a brief description to know the differences between each one. The format of the link will be .json. If by some chance it does not allow us to install a game with the source that we are using it is simply because it is not available and we will have to use another one (all the sources are also provided by the creator of the program)

Download sources: https://hydralinks.cloud/

Step 4
Now that we have already added the download source depending on which one it is we can add a game or another, in my case I am using this called FitGirl: https://hydralinks.cloud/sources/fitgirl.json
As example I will try to download GTA5, simply I must look for it in catalog pressing where it says download sources and there will appear destinas versions or packs of the game.

Step 5

Now that we have selected the version we will be asked how we want to download the game files Torrent, TorBox or Real-Debrid. I don't know what differences there are between each one, I will simply use the Torrent method.
Also we will have to select where we want to install it and we will mark the box to decompress files automatically.


Ready, we just have to wait, once the game is downloaded we can run it from the Hydra launcher in our game library.
