+Example:

 ```javascript
-import { v1 as uuidv1 } from 'uuid';

+
+NIL_UUID; // ⇨ '00000000-0000-0000-0000-000000000000'
 ```
 
-### Create Version 3 or Version 5 (Namespace) UUIDs
+### uuid.parse(str)
 
-&#x26a0;&#xfe0f; Version 3 and Version 5 UUIDs are basically the same, differing only in the underlying hash algorithm. Note that per the RFC, "_If backward compatibility is not an issue, SHA-1 [Version 5] is preferred_."

-&#x26a0;&#xfe0f; If using a custom namespace **be sure to generate your own namespace UUID**. You can grab one [here](https://www.uuidgenerator.net/).

+| [`options`] | `Object` with one or more of the following properties: |
+| [`options.node` ] | RFC "node" field as an `Array[6]` of byte values (per 4.1.6) |
+| [`options.clockseq`] | RFC "clock sequence" as a `Number` between 0 - 0x3fff |
+| [`options.msecs`] | RFC "timestamp" field (`Number` of milliseconds, unix epoch) |
+| [`options.nsecs`] | RFC "timestamp" field (`Number` of nanseconds to add to `msecs`, should be 0-10,000) |
+| [`options.random`] | `Array` of 16 random bytes (0-255) |
+| [`options.rng`] | Alternative to `options.random`, a `Function` that returns an `Array` of 16 random bytes (0-255) |
+| [`buffer`] | `Array \| Buffer` If specified, uuid will be written here in byte-form, starting at `offset` |
+| [`offset` = 0] | `Number` Index to start writing UUID bytes in `buffer` |
+| _returns_ | UUID `String` if no `buffer` is specified, otherwise returns `buffer` |
+| _throws_ | `Error` if more than 10M UUIDs/sec are requested |
+
+Note: The default [node id](https://tools.ietf.org/html/rfc4122#section-4.1.6) (the last 12 digits in the UUID) is generated once, randomly, on process startup, and then remains unchanged for the duration of the process.
+
+Note: `options.random` and `options.rng` are only meaningful on the very first call to `v1()`, where they may be passed to initialize the internal `node` and `clockseq` fields.

+
 ```javascript

-  - `random` - (Number[16]) Array of 16 numbers (0-255) to use in place of randomly generated values. Takes precedence over `options.rng`.
-  - `rng` - (Function) Random # generator function that returns an Array[16] of byte values (0-255). Alternative to `options.random`.
-- `buffer` - (Array | Buffer) Array or buffer where UUID bytes are to be written.
-- `offset` - (Number) Starting index in `buffer` at which to begin writing.
+```javascript
