+# Image-to-ASCII-Art
+The title is self-explanatory.
+
+# Requirements
+- Pillow Module for Python3
+- PyQt5 and PyQt-tools for Python3
+
+```
+pip install pillow
+pip install pyqt5
+pip install pyqt5-tools
+```
+
+# File to Run
+- program.pyw
+
+# Test
+See test.txt file
+
+# Program
+![](program.png)
+
+# A Little Explanation
+- Size: Bigger is better. The larger it is, the larger the image in the text file. Resolution also increases.
+- Ratio: Smaller is better. This value is for the vertical length of the picture to be created not to be longer than normal.
+
+# Best Settings
+`Size: 1000  Ratio: 0.2`
+
+`Size: 150  Ratio: 0.3`
+
+# Important Note
+The larger the size part, the larger the picture, and probably only a small part of the picture will be visible in the text file when it exceeds a certain value. ***Zoom out in your text editor to see the whole picture.***
