-## Installation
-
-`$ npm install mrz`
-
-## Example
-
-```js
-const parse = require('mrz').parse;
-
-const mrz = [
-  'I<UTOD23145890<1233<<<<<<<<<<<',
-  '7408122F1204159UTO<<<<<<<<<<<6',
-  'ERIKSSON<<ANNA<MARIA<<<<<<<<<<',
-];
-
-var result = parse(mrz);
-console.log(result);
+```bash
+npm run build-py
 ```
 
-## API
-
-### `parse(mrz, [options])`
-
-Parses the provided MRZ. The argument can be an array of lines or a single string
-including line breaks. This function throws an error if the input is in an
-unsupported format. It will never throw an error when there are invalid fields
-in the MRZ. Instead, the `result.valid` value will be `false` and
-details about the invalid fields can be found in `result.details`.
-
-#### Options
-
-##### `options.autocorrect`
-
-If set to `true`, some ambiguous characters will be automatically corrected by the parser if the field is supposed to
-only contain numeric or alphabetic characters.
-For example, in a date field, the letter "O" will be converted to the number "0".
-
-Information about autocorrected characters will be added to the result details.
-
-Default: `false`.
-
-#### Shape of the parse result
-
-##### result.format
-
-String identifying the format of the parsed MRZ. Supported formats are:
-
-- TD1 (identity card with three MRZ lines)
-- TD2 (identity card with two MRZ lines)
-- TD3 (passport)
-- SWISS_DRIVING_LICENSE
-- FRENCH_NATIONAL_ID
-
-##### result.valid
-
-`true` if all fields are valid. `false` otherwise.
+### Usage
 
-##### result.fields
-
-Object mapping field names to their respective value. The value is set to `null`
-if it is invalid. The value may be different from the raw value. For example,
-`result.fields.sex` will be "male" when the raw value was "M".
-
-##### result.documentNumber
-
-The document number, as can be found in the visual elements of the document, outside the MRZ. For some documents, it may
-be composed of multiple parsed fields. It may also not include the MRZ field named `documentNumber`. If any of the used
-fields is invalid, this field will be set to `null`.
-
-##### result.details
-
-Array of objects describing all parsed fields. Its structure is:
-
-- label {string} - Full english term for the field.
-- field {string|null} - Name of the field in `result.fields`. Null for some fields such as separators that don't contain a value.
-- value {string} - Value of the field (if it's valid) or `null`.
-- valid {boolean} - Whether the field is valid.
-- ranges {Array} - Array of ranges that are necessary to compute this field.
-  Ranges are objects with `line`, `start`, `end` and `raw`.
-- line {number} - Index of the line where the field's value is located.
-- start {number} - Index of the start of the field's value in `line`.
-- end {number} - Index of the end of the field's value in `line`.
-- error {undefined|string} - Contains a message describing the error if the field is invalid.
-- autocorrect {array} - Contains indices of characters that were autocorrected and their original value.
-
-### `formats`
-
-Static mapping of supported formats.
-
-### `states`
-
-Static mapping of state code to state name.
