+Pure JavaScript library for parsing Shapefiles, returns Geojson projected into WGS84 lat lons.
 
 ## Usage
 
-Fore use in rollup, node and where ever ESM modules are used we have a lovely package you can install via npm or yarn or whatever.
+For use in node, rollup, webpack and where ever ESM modules are used we have a lovely package you can install via npm or yarn or whatever.
 
     npm install shpjs --save
 
-If you need a stand alone file to include in your webpage the old fasion when then you can grab the built version that's either included in the repo or you can use unpkg.
+If you need a stand alone file to include in your webpage the old fashioned way then you can grab the built version that's either included in the repo or you can use unpkg.
 
     https://unpkg.com/shpjs@latest/dist/shp.js
 
 NOTE: as of V5 the version you get though npm is an ES module, so make sure you import it instead of requiring it.
 
+When using this library in some sort of bundler for the browser, no polyfills for node apis are required, the only thing needed is some sort of dependency resolver plugin like [rollup node-resolve](https://www.npmjs.com/package/@rollup/plugin-node-resolve) if your bundler doesn't have it, you are almost certainly already using one to get this library anyway.
+
 ## API
 
-Has a function `shp` which accepts a string which is the path the she shapefile minus the extension and returns a promise which resolves into geojson.
+There are 3 ways to use it:
+
+1\. you can pass it a url to a shapefile, either to the shapefile itself (with or without the .shp suffix)
 
 ```javascript
 	import shp from 'shpjs';
 	//for the shapefiles in the folder called 'files' with the name pandr.shp
-	const geojson = await shp("files/pandr");
+	const geojson = await shp("files/pandr.shp");
 ```
-or you can call it on a .zip file which contains the shapefile
+
+or you can pass it a url to a a .zip file which contains the shapefile
 
 ```javascript
 	//for the shapefiles in the files folder called pandr.shp
 	const geojson = await shp("files/pandr.zip");
-	//see bellow for whats here this internally call shp.parseZip()
 ```
 
-or if you got the zip some other way (like the [File API](https://developer.mozilla.org/en-US/docs/Web/API/File)) then with the arrayBuffer you can call
+2\. you can pass in in a binary buffer (ArrayBuffer, TypedArray, DataView, Node Buffer) containing a zip file containing at least one shapefile like from a file in node:
 
 ```javascript
-const geojson = await shp(buffer);
+// in node
+const data = await fs.readFile('./path/to/shp.zip');
+const geojson = await shp(data);
 ```
-If there is only one shp in the zipefile it returns geojson, if there are multiple then it will be an array.  All of the geojson objects have an extra key `fileName` the value of which is the
-name of the shapefile minus the extension (I.E. the part of the name that's the same for all of them)
-
+or the [File API](https://developer.mozilla.org/en-US/docs/Web/API/File) in the browser
 
-## Advanced API
-There are also a few internal methods that are exposed for if you have to do some more complicated stuff.  These are named exports in the ESM version or properties on the main `shp` function in the bundled version.
+```javascript
+// in browser from some sort of file upload
+const data = await file.arrayBuffer()
+const geojson = await shp(data);
+```
 
-- `parseShape`: takes a buffer containing the contents of a `.shp` file and optionally a `.prj` STRING and returns geometries.
-- `parseDbf`: just a shortcut to [parseDBF](https://github.com/calvinmetcalf/parsedbf) takes the same arguments, though will do some type coertion that the stand alone library won't.
-- `combine`: takes the results of the two aformentioned functions and combines them into a geojson document.
+3\. You can pass in an object with `shp`, `dbf`, `prj`, and `cpg` properties.
 
 ```javascript
-import {combine, parseShp, parseDbf} from shpjs;
-combine([parseShp(shpBuffer, /*optional prj str*/),parseDbf(dbfBuffer)]);
+const object = {}
+object.shp = await fs.readFile('./path/to/file.shp');
+// dbf is optional, but needed if you want attributes
+object.dbf = await fs.readFile('./path/to/file.dbf');
+// prj is optional, but needed if your file is in some projection you don't want it in
+object.prj = await fs.readFile('./path/to/file.prj');
+// cpg is optional but needed if your dbf is in some weird (non utf8) encoding.
+object.cpg = await fs.readFile('./path/to/file.cpg');
+
+const geojson = await shp(object)
 ```
