+# Storage Usage Monitor
+
+A lightweight Go utility that displays storage usage information with a visual progress bar and color-coded output for easy monitoring.
+
+## Features
+
+- 📊 Visual storage usage representation with progress bars
+- 🎨 Color-coded output for better readability
+- 📱 Supports multiple storage devices (internal, external, RAID arrays)
+- 🔢 Displays total, used, and free space in appropriate units
+- 🖥️ Clean, formatted output for terminal viewing
+
+## Supported Storage Types
+
+- Android internal storage
+- SD cards
+- RAID arrays (md devices)
+- Any mountable storage device
+
+## Installation
+
+1. Ensure you have Go installed on your system
+2. Clone or download this repository
+3. Build the executable:
+   ```bash
+   CGO_ENABLED=0 GOOS=linux GOARCH=arm GOARM=5 go build -trimpath -v -x -o ./bin/storage ./main.go
+```
+
+Usage
+
+Run the compiled binary:
+
+```bash
+./storage
+```
+
+Output Example
+
+```
+=== Úložiště ===
+Interní úložiště
+  ##############################  85% used
+  Total: 64 G | Used: 54 G | Free: 10240 M
+
+SD karta
+  ##################           60% used
+  Total: 128 G | Used: 77 G | Free: 51200 M
+```
+
+Customization
+
+To monitor different storage paths, edit the storages slice in the main() function:
+
+```go
+storages := []Storage{
+    {"/path/to/your/storage", "Custom Label"},
+    {"/another/path", "Another Label"},
+}
+```
+
+Requirements
+
+· Go 1.11 or higher
+· Linux/Unix-like system with df command available
+· Terminal that supports ANSI color codes
+
