This readme is a work in progress. Inclided in the data directory is story-points.json. This file contains 100 bugs pulled from the Lodash github repo. I threw story point estimates on it myself. This obviously isn't useful. You'll need to get your own training set to replace the one in story-points.json.
You'll also probably need to modify line 3 in helpers.js. This function is what takes your JSON structure and converts them into a single text item. Unless the shape of your training set is the same, update this function to concat all the fields you care about.
npm i
// Train the model
npm run train
// Run a prediction
npm run predict "your story here"
