+    - ffmpeg: https://www.ffmpeg.org/download.html
+```
+
+## Commands
+
+### Options
+
+    - input-file
+        - file to be converted (original is kept)
+        - default: input.mp4/input.gif/input.png depending on command used
+
+    - output-file
+        - file to save the converted file
+        - default: input.mp4/input.gif/input.png depending on command used
+
+    - pixel-size
+        - size of ASCII character (output resolution will be multipied by this amount, downscaling is recomended)
+        - default: 24
+
+    - font-size-modifier
+        - increase ASCII character size by set pixes without increasing space it takes. Could be useful when using bigger pixel-size setting
+        - default: 4
+
+    - scaled-size
+        - pixels in width (result will be scaled-size * pixel-size of width)
+        - default: 120
+
+    - fps
+        - frames per second of generated file
+        - default: 10
