# Getting Started with Vim 📝

## 1. Installing Vim

To install Vim on a Debian‑based system (like Ubuntu), run:

```bash
sudo apt update
sudo apt install vim
```

---

## 2. Opening Files or Directories

* **Open a file**

  ```bash
  vim <filename>
  ```

* **Open a directory**

  ```bash
  vim <directory_name>
  ```

  (This opens Vim’s file browser—helpful for navigating and editing multiple files.)

---

## 3. Vim Modes

Vim works in multiple modes—here are the core ones:

1. **Normal mode** – The default mode; used for navigation and commands.
2. **Insert mode** – For editing text; enter it by pressing `i`, `a`, or `o`.
3. **Visual mode** – For selecting text; enter it with `v`, `V`, or `Ctrl+v`.

## 4. Essential Commands

(Type these in **Normal mode** and then press Enter when needed)

| Command     | Description                               |
| ----------- | ----------------------------------------- |
| `:w`        | Save (write changes to the current file)  |
| `:w <name>` | Save changes to a specified file `<name>` |
| `:wq`       | Save and quit Vim                         |
| `:q`        | Quit (only if no unsaved changes exist)   |
| `:q!`       | Quit without saving (discard all changes) |

## 5. Handy Shortcuts

These are core shortcuts used in **Normal mode**:

## 6. Quick Usage Flow

1. **Start Vim**:

## 7. Tips & Tricks

* **Visual mode**:
  Press `v` to start selecting character by character, `V` for line selection, or `Ctrl+v` for block-wise selection.

  * Use a number before a command, e.g., `5dd` deletes 5 lines
