MOD Essentials [ENG]

Its own nature is making it not so stable but also easily modifiable as advantage. As a result, mods are now countless, and I can imagine beginners having hard times searching them and choose which one to pick between existing sharing platforms.
I do have trouble myself everytime I get to play again this awesome space simulation. There is always a search work to do before installing a mod, to understand if it is the latest version, if it is compatible with actual KSP version, or if there is any integration needed to apply.

The point of this guide is to share my search work with everyone, listing most deserving mods and providing the correct links to find them.

I'll keep the links updated as much as possible alongside KSP and its mods developing. Here are some suggestion which I do recommend to newcomers to read:

• It is a good idea to backup a KSP fresh installation folder.
  Some mods may not be compatible to each other or may be installed wrong by mistake, in other words, using mods things may go badly in the wrong way and the game may not work anymore. If you have a backup you just have to delete the game folder and put back the fresh one in its place without having to download it again (do not forget to backup save game folder!).
  
• Don't install more than one mod at a time if you are not aware of its behaviour and compatibility.
  Going on step by step is always the best way, when you do not know a mod you should test it first to understand if it works properly. In this way you can keep track of what is working and what's not.
  
• CKAN[forum.kerbalspaceprogram.com] is an interesting mod manager developed by community.
  This little software lists (almost) all the mods, you just have to pick and it'll do anything else by itself including download, install and advice you of dependecies or conflicts; however, we can say for sure that installing mods on KSP is such a delicate task that deserve to be manually done. Some people use CKAN, others don't. I did use it for a long time and I've found it convenient, the choice is yours.
  
• Automatic updates and mods are not good friends. When a KSP update hits the release you have to be very careful because severe losses may happen. Why? Because when game version change, installed mods are no longer compatible until they gets updated too. In this scenery, loading a game without necessary mods affected vessels will be removed entirely; what is worst, KSP automatically save the game. Without a backup your vessels will be lost with no possible recover.
  It is an easy task to prevent such disgrace, just take one of the following actions:
  
  1. deactivate automatic updates for KSP, easy-peasy;
     
  2. before running the game recently updated, backup the save folder;
     
  3. start a new game and do not load older games until all necessary mods are updated and installed;
• Do not stop to these lists.
  Use this guide as a starting place and then search and test in the multitude of existing mods around this game. Take into consideration that most probably your favourite mod is not listed here and you are loosing some good fun time until you find it.
