+# Video Watermarker
+
+This script watermarks the entire video given the watermark text, it's position and margin. First the frames of the video are converted into images, then text is drawn and then saved in a list of images. After this entire process, the watermarked images are combined back to video  and then audio is added to the final output. The residual files created during the process are deleted when they are of no use.
+
+# How to use?
+
+Just type:
+
+`python app.py video-location watermark_location margin watermark_text `
+
+video_location: location of the video
+
+watermark_location: 
+- RT (Right Top)
+- RB (Right Bottom)
+- LB (Left Bottom)
+- LT (Left Top)
+- C (Center)
+
+Example:
+
+`python app.py sample.mp4 RT 5 Kaustubh Gupta`
+
+# Requirements
+
+Before running the script, just run the command
+
+`pip install -r requirements.txt`
+
+and all dependices will be installed
+
