 ## What is it for?

  You can simply use `pip install -r requirements.txt` too.
 
+## Docker image
+
+If you would rather not have to install anything to use TextRecognitionDataGenerator, you can pull the docker image.
+
+```
+docker pull belval/trdg:latest
+
+docker run /output/path/:/app/out/ -t belval/trdg:latest python3 run.py [args]
+```
+
+The path (`/output/path/`) must be absolute.

 ## New
 - Add `--font` to use only one font for all the generated images (Thank you @JulienCoutault!)
 - Add `--fit` and `--margins` for finer layout control
