 ## Library Usage

-First import the library with:
+> **Note:** The library may throw errors during Go tests due to some unresolved bugs with the [consolesize-go](https://github.com/nathan-fiscaletti/consolesize-go) package (Only during tests, not main program execution).
+
+First, install the library with:
 ```
-go get github.com/TheZoraiz/ascii-image-converter/aic_package
+go get -u github.com/TheZoraiz/ascii-image-converter/aic_package
 ```

-The library is to be used as follows:
+For an image:
+
 ```go
 package main

 import (
 	"fmt"
+
 	"github.com/TheZoraiz/ascii-image-converter/aic_package"
 )

 func main() {
-	// If image is in current directory. This can also be a URL to an image.
-	imagePath := "myImage.jpeg"
+	// If file is in current directory. This can also be a URL to an image or gif.
+	filePath := "myImage.jpeg"

 	flags := aic_package.DefaultFlags()

-	// This part is optional. You can directly pass flags variable to ConvertImage() if you wish.
-	// For clarity, all flags are covered in this example.
-	flags["complex"] = true  // Use complex character set
-	flags["dimensions"] = []int{50, 25} // 50 by 25 ascii art size
-	flags["savePath"] = "."  // Saves to current directory
-	flags["negative"] = true  // Ascii art will have negative color-depth
-	flags["colored"] = true  // Keep colors from original image
-	flags["customMap"] = " .-=+#@"  // Starting from darkest to brightest shades. This overrites "complex" flag
-	flags["flipX"] = true  // Flips ascii art horizontally
-	flags["flipY"] = true  // Flips ascii art vertically
+	// This part is optional.
+	// You can directly pass default flags variable to aic_package.Convert() if you wish.
+	// There are more flags, but these are the ones shown for demonstration
+	flags.Dimensions = []int{50, 25}
+	flags.Colored = true
+	flags.SaveTxtPath = "."
+	flags.SaveImagePath = "."
+	flags.CustomMap = " .-=+#@"
+	flags.FontFilePath = "./RobotoMono-Regular.ttf" // If file is in current directory
+	flags.SaveBackgroundColor = [4]int{50, 50, 50, 100}

-	// Return ascii art as a single string
-	asciiArt, err := aic_package.ConvertImage(imagePath, flags)
+	// Note: For environments where a terminal isn't available (such as web servers), you MUST
+	// specify atleast one of flags.Width, flags.Height or flags.Dimensions
+
+	// Conversion for an image
+	asciiArt, err := aic_package.Convert(filePath, flags)
 	if err != nil {
 		fmt.Println(err)
 	}

 	fmt.Printf("%v\n", asciiArt)
 }
+```
+<br>
+
+> **Note:** GIF conversion is not advised as the function may run infinitely, depending on the GIF. More work needs to be done on this to make it more library-compatible.
+
+For a GIF:
+
+```go
+package main
+
+import (
+	"fmt"
+
+	"github.com/TheZoraiz/ascii-image-converter/aic_package"
+)
+
+func main() {
+	filePath = "myGif.gif"
+
+	flags := aic_package.DefaultFlags()
+
+	_, err := aic_package.Convert(filePath, flags)
+	if err != nil {
+		fmt.Println(err)
+	}
+}
