 Changes:
  * Includes [PR from axon014](https://github.com/spite/THREE.MeshLine/pull/73) to correct line widths (should now work with orthographic camera)
  * BufferGeometry now supported
- * New ```setVertices``` and ```setBufferArray``` functions so you no longer need to create a geometry first
- * ```MeshLine``` is now a ```THREE.BufferGeometry```
+ * New ```setVertices``` and ```setBufferArray``` functions so you no longer need to create a geometry prior to a ```MeshLine```
+ * ```MeshLine``` now extends ```THREE.BufferGeometry``` and can be used in a mesh as a geometry
  * Extra setters and getters to help with declaritive libraries like [react-three-fiber](https://github.com/react-spring/react-three-fiber)
  * Old api should still work as expected

-* Include script
-* Create and populate a geometry
-* Create a MeshLine and assign the geometry
-* Create a MeshLineMaterial
-* Use MeshLine and MeshLineMaterial to create a THREE.Mesh
+# How to use
 
-#### Include the script ####
+#### Fetch imports
 
-Include script after THREE is included
-```js
-<script src="THREE.MeshLine.js"></script>
-```
-or use npm to install it
-```
-npm i threejs-meshline
-```
-and include it in your code (don't forget to require three.js)
-```js
-var THREE = require( 'three' );
-var MeshLine = require( 'threejs-meshline' );
-```
-or
 ```js
-import * as THREE from "three";
 import { MeshLine, MeshLineMaterial } from 'threejs-meshline'
 ```
 
-##### Create and populate a geometry #####
+#### Create and populate a geometry
 
-First, create the list of vertices that will define the line. ```MeshLine``` accepts ```THREE.Geometry``` (looking up the ```.vertices``` in it) and ```Array```/```Float32Array```. ```THREE.BufferGeometry``` coming soon, and may be others like ```Array``` of ```THREE.Vector3```.
+First, create the list of vertices that will define the line. `MeshLine` accepts `THREE.Geometry` (looking up the `.vertices` in it) and `Array`/`Float32Array`. Comong soon: `THREE.BufferGeometry` and `THREE.Vector3` arrays.
 
 ```js
-var vertices = [];
-for( var j = 0; j < Math.PI; j += 2 * Math.PI / 100 ) {
-	var v = new THREE.Vector3( Math.cos( j ), Math.sin( j ), 0 );
-	vertices.push( v );
-}
+const vertices = [];
+for(let j = 0; j < Math.PI; j += 2 * Math.PI / 100)
+  vertices.push(new THREE.Vector3( Math.cos(j), Math.sin(j), 0))
 ```
 
-##### Create a MeshLine and assign the geometry #####
+#### Create a MeshLine and assign the geometry
 
-Once you have that, you can create a new ```MeshLine```, and call ```.setVertices()``` passing the vertices.
+Once you have that, you can create a new `MeshLine`, and call `.setVertices()` passing the vertices.
 
 ```js
-var line = new MeshLine();
-line.setVertices( vertices );
+const line = new MeshLine()
+line.setVertices(vertices)
 ```
 
-Note: ```.setVertices``` accepts a second parameter, which is a function to define the width in each point along the line. By default that value is 1, making the line width 1 * lineWidth.
+Note: `.setVertices` accepts a second parameter, which is a function to define the width in each point along the line. By default that value is 1, making the line width 1 * lineWidth.
 
 ```js
-line.setGeometry( geometry, function( p ) { return 2; } ); // makes width 2 * lineWidth
-line.setGeometry( geometry, function( p ) { return 1 - p; } ); // makes width taper
-line.setGeometry( geometry, function( p ) { return 2 + Math.sin( 50 * p ); } ); // makes width sinusoidal
+line.setGeometry(geometry, p => 2)                    // makes width 2 * lineWidth
+line.setGeometry(geometry, p => 1 - p)                // makes width taper
+line.setGeometry(geometry, p => 2 + Math.sin(50 * p)) // makes width sinusoidal
 ```
 
-##### Create a MeshLineMaterial #####
+#### Create a MeshLineMaterial
 
-A ```MeshLine``` needs a ```MeshLineMaterial```:
+A `MeshLine` needs a `MeshLineMaterial`:
 
 ```js
-var material = new MeshLineMaterial(OPTIONS);
+const material = new MeshLineMaterial(OPTIONS)
 ```
 
 By default it's a white material of width 1 unit.
 
-```MeshLineMaterial``` has several attributes to control the appereance of the ```MeshLine```:
-
-* ```map``` - a ```THREE.Texture``` to paint along the line (requires ```useMap``` set to true)
-* ```useMap``` - tells the material to use ```map``` (0 - solid color, 1 use texture)
-* ```alphaMap``` - a ```THREE.Texture``` to use as alpha along the line (requires ```useAlphaMap``` set to true)
-* ```useAlphaMap``` - tells the material to use ```alphaMap``` (0 - no alpha, 1 modulate alpha)
-* ```repeat``` - THREE.Vector2 to define the texture tiling (applies to map and alphaMap - MIGHT CHANGE IN THE FUTURE)
-* ```color``` - ```THREE.Color``` to paint the line width, or tint the texture with
-* ```opacity``` - alpha value from 0 to 1 (requires ```transparent``` set to ```true```)
-* ```alphaTest``` - cutoff value from 0 to 1
-* ```dashArray``` - the length and space between dashes. (0 - no dash)
-* ```dashOffset``` - defines the location where the dash will begin. Ideal to animate the line.
-* ```dashRatio``` - defines the ratio between that is visible or not (0 - more visible, 1 - more invisible).
-* ```resolution``` - ```THREE.Vector2``` specifying the canvas size (REQUIRED)
-* ```sizeAttenuation``` - makes the line width constant regardless distance (1 unit is 1px on screen) (0 - attenuate, 1 - don't attenuate)
-* ```lineWidth``` - float defining width (if ```sizeAttenuation``` is true, it's world units; else is screen pixels)
-* ```near``` - camera near clip plane distance  (REQUIRED if ```sizeAttenuation``` set to false)
-* ```far``` - camera far clip plane distance  (REQUIRED if ```sizeAttenuation``` set to false)
-
-If you're rendering transparent lines or using a texture with alpha map, you should set ```depthTest``` to ```false```, ```transparent``` to ```true``` and ```blending``` to an appropriate blending mode, or use ```alphaTest```.

+`MeshLineMaterial` has several attributes to control the appereance of the `MeshLine`:

+If you're rendering transparent lines or using a texture with alpha map, you should set `depthTest` to `false`, `transparent` to `true` and `blending` to an appropriate blending mode, or use `alphaTest`.
+
+#### Use MeshLine and MeshLineMaterial to create a THREE.Mesh #####
 
 Finally, we create a mesh and add it to the scene:
 
 ```js
-var mesh = new THREE.Mesh( line, material ); // this syntax could definitely be improved!
-scene.add( mesh );
+const mesh = new THREE.Mesh(line, material)
+scene.add(mesh)
 ```

 threejs-meshline is a replacement for `THREE.Line`, it allows you to create lines with varable widths. It is a fork of Jaume Sanchez Elias [THREE.meshline](https://github.com/spite/THREE.MeshLine) as the repo no longer appears to be maintained.
 
- * Supports BufferGeometry
- * Extends `THREE.BufferGeometry` and can be used in regular meshes as a geometry
- * New `setVertices` and `setBufferArray` functions so you no longer need to create a geometry prior to a `MeshLine`
- * Raycast is exposed as `MeshLineRaycast` and can be used like `mesh.raycast = MeshLineRaycast`
- * Raycast accounts for line width
- * Extra setters and getters to help with declaritive libraries like [react-three-fiber](https://github.com/react-spring/react-three-fiber)

 `MeshLineMaterial` has several attributes to control the appereance of the `MeshLine`:
 
-* `map` - a `THREE.Texture` to paint along the line (requires `useMap` set to true)
-* `useMap` - tells the material to use `map` (0 - solid color, 1 use texture)
-* `alphaMap` - a `THREE.Texture` to use as alpha along the line (requires `useAlphaMap` set to true)
-* `useAlphaMap` - tells the material to use `alphaMap` (0 - no alpha, 1 modulate alpha)
-* `repeat` - THREE.Vector2 to define the texture tiling (applies to map and alphaMap - MIGHT CHANGE IN THE FUTURE)
-* `color` - `THREE.Color` to paint the line width, or tint the texture with
-* `opacity` - alpha value from 0 to 1 (requires `transparent` set to `true`)
-* `alphaTest` - cutoff value from 0 to 1
-* `dashArray` - the length and space between dashes. (0 - no dash)
-* `dashOffset` - defines the location where the dash will begin. Ideal to animate the line.
-* `dashRatio` - defines the ratio between that is visible or not (0 - more visible, 1 - more invisible).
-* `resolution` - `THREE.Vector2` specifying the canvas size (REQUIRED)
-* `sizeAttenuation` - makes the line width constant regardless distance (1 unit is 1px on screen) (0 - attenuate, 1 - don't attenuate)
-* `lineWidth` - float defining width (if `sizeAttenuation` is true, it's world units; else is screen pixels)

-threejs-meshline is a replacement for `THREE.Line`, it allows you to create lines with varable widths. It is a fork of Jaume Sanchez Elias [THREE.meshline](https://github.com/spite/THREE.MeshLine) as the repo no longer appears to be maintained.

-- Supports BufferGeometry
-- Extends `THREE.BufferGeometry` and can be used in regular meshes as a geometry
-- New `setVertices` and `setBufferArray` functions so you no longer need to create a geometry prior to a `MeshLine`
-- Raycast is exposed as `MeshLineRaycast` and can be used like `mesh.raycast = MeshLineRaycast`
-- Raycast accounts for line width
-- Extra setters and getters to help with declaritive libraries like [react-three-fiber](https://github.com/react-spring/react-three-fiber)
