+# tensorflow-load-csv
+
+A library that aims to remove the overhead of creating tensors from CSV files completely; allowing you to dive right into the fun parts of your ML project.
+
+- Lightweight.
+- Fast.
+- Flexible.
+- TypeScript compatible.
+- 100% test coverage.
+
+## Installation
+
+NPM:
+sh
+```
+npm install tensorflow-load-csv
+```
+
+Yarn:
+sh
+```
+yarn add tensorflow-load-csv
+```
+
+## Usage
+
+Simple usage:
+js
+```
+import loadCsv from 'tensorflow-load-csv';
+
+const { features, labels } = loadCsv('./data.csv', {
+  featureColumns: ['lat', 'lng', 'height'],
+  labelColumns: ['temperature'],
+});
+```
+
+Advanced usage:
+js
+```
+import loadCsv from 'tensorflow-load-csv';
+
+const {
+  features,
+  labels,
+  testFeatures,
+  testLabels,
+  mean,    // tensor holding mean of features, ignores testFeatures
+  variance // tensor holding variance of features, ignores testFeatures
+} = loadCsv('./data.csv', {
+  featureColumns: ['lat', 'lng', 'height'],
+  labelColumns: ['temperature'],
+  shuffle: true,
+  splitTest: true,   // Splits your data in half. You can also provide a certain row count for the test data.
+  prependOnes: true, // Prepends a column of 1s to your features and testFeatures tensors, useful for linear regression.
+  standardise: true, // Calculates the standard deviation for each feature and testFeature column and standardises the values in those columns. Does not touch labels.
+});
+```
