+> Postgres date output parser
+
+This package parses [date/time outputs](https://www.postgresql.org/docs/current/datatype-datetime.html#DATATYPE-DATETIME-OUTPUT) from Postgres into Javascript `Date` objects. Its goal is to match Postgres behavior and preserve data accuracy.
+
+If you find a case where a valid Postgres output results in incorrect parsing (including loss of precision), please [create a pull request](https://github.com/bendrucker/postgres-date/compare) and provide a failing test.
+
+**Supported Postgres Versions:** `>= 9.6`
+
+All prior versions of Postgres are likely compatible but not officially supported.
+
+## Install
+
+```
+$ npm install --save postgres-date
+```
+
+
+## Usage
+
+```js
+var parse = require('postgres-date')
+parse('2011-01-23 22:15:51Z')
+// => 2011-01-23T22:15:51.000Z
+```
+
+## API
+
+#### `parse(isoDate)` -> `date`
+
+##### isoDate
+
+*Required*  
+Type: `string`
+
+A date string from Postgres.
+
+## Releases
+
+The following semantic versioning increments will be used for changes:
+
+* **Major**: Removal of support for Node.js versions or Postgres versions (not expected)
+* **Minor**: Unused, since Postgres returns dates in standard ISO 8601 format
+* **Patch**: Any fix for parsing behavior
