+# My Neovim Configuration
+
+A fast, modern, and highly capable Neovim setup tailored for full-stack and systems development. It uses `mini.deps` for blazingly fast plugin management and heavily leverages the `mini.nvim` ecosystem to keep bloat to an absolute minimum.
+
+## Core Capabilities
+
+* **Modern Autocompletion:** Powered by the Rust-based `blink.cmp` for zero-latency, out-of-the-box completion with built-in snippet support.
+* **Intelligent Formatting (`conform.nvim`):** Seamless asynchronous formatting for a massive array of languages. 
+  * *Special Rule:* Rust files automatically format on save via `rustfmt`.
+* **Real-time Linting (`nvim-lint`):** Automatically lints Python files with `flake8` every time the file is saved.
+* **Robust Language Server Protocol (LSP):** Fully automated LSP installation and configuration via `mason.nvim` and `mason-lspconfig`. Includes specialized C# support via Roslyn.
+* **Aesthetic & UI:** * Beautiful `Catppuccin` (Mocha/Latte) color scheme.
+  * Informative status lines and tab lines via `mini.statusline` and `mini.tabline`.
+  * Customized floating diagnostic windows and rounded borders.
+* **Typst Integration:** Live Typst previewing with `typst-preview.nvim` and compilation via `tinymist`.
+* **Integrated Terminal:** Floating terminal toggle via `toggleterm.nvim`.
+

+* **.NET:** C# (`roslyn`, `rzls`, `csharpier`)
+* **Scripting & Data:** Python (`pyright`, `isort`, `black`, `flake8`), Lua (`lua_ls`, `stylua`), Bash (`bashls`, `shfmt`)
+* **Web Ecosystem:** HTML, CSS, JSON, YAML, JavaScript, TypeScript, React (`prettier`, various LSPs)
