I prefer text based tutorials that actually has good formatting. this is an example of bad formatting, don't believe me? Step 1 and 2 are larger, step 3 onward is same size as everything else, folder lists are not even listed in any shape or form for a numbered, bulleted, or otherwise -list. The mention of renaming and saying the ".jar" is automatic can also be false considering not everyone hides files extension (of which btw, I disagree with hiding them at all regardless of expertise level) thus when they rename a file, they can inadvertently rename it with no extension causing it not to be a known file type at all and thus the instructions fail. The line mentioning "Good job" is unnecessarily all capitalized. There's no reason for this, it looks like someone doesn't know how to handle when to capitalize or when not to, and often is just plain over-"yelling." There's claims of winrar being the best, which can highly be debated. A point of a guide is not to shove ideologies of software onto other people, but rather to make recommendations, the line would be better phrased, "I personally use WinRAR." Of which it indicates nothing of opinion but rather what was used in this process as a preferred application. Let me see. Is there anything else that really strikes me in this guide that is unnecessary? Why, yes, there is. The entire first three "paragraphs." They're already here of their own volition and don't need a reason to read a guide about installing Bukkit and plugins. There are also other countless lines that distract from the point of the actual guide and thus increase the time it takes to actually get to the important information. While Curunir mentions that he preferred this since it isn't covered over YouTube nonsense, it is covered in text nonsense. So, I cannot recommend this guide to anyone in the current state it is in.
Edit: Re-read my post, removed a small bit of it in regards to WinRAR due to an accidental opinion being put into there.
