It's kinda obvious from the context if you know that space, but yes, it's leaving out many explanations. It's not well written for random visitors. Anyway, Obsidian is a knowledge-tool, using Markdown. It's for taking notes, collecting information and aims to support the user in building their network of knowledge. It's pretty powerful for a markdown-editor/manager, especially because it's supporting plugins, which is feeding a small community of developers bringing up all kind of ways to enhance Obsidian. Obsidian is very popular and well known on this site, though attention for this space comes in waves, and I would say the big hype is over for the moment. So depending on what you read here, it's possible you just missed it.
