6. After the process has finished, you will have a final.traineddata in the src/output directory. Use this in your Tesseract project

Configuration

Change the following environment values in docker-compose.yml:

TESSTRAIN_FONT	Agency FB Condensed	The name of the font (not the filename)
TESSTRAIN_LANG	eng	The language of the training data
TESSTRAIN_MAX_PAGES	10	Training text size
TESSTRAIN_MAX_ITERATIONS	400	Number of iterations for the neural network, more will give a better result but may also lead to overfitting (bad)
