 1 | # Sell
 2 | 
 3 | > Cross-browser text input selection made simple
 4 | 
 5 | # Install
 6 | 
 7 | ```shell
 8 | npm install sell --save
 9 | ```
10 | 
11 | # Usage
12 | 
13 | Note that `el` must be either an `<input>` element or a `<textarea>`.
14 | 
15 | # `sell(el)`
16 | 
17 | Returns an object like `{ start: 1, end: 3 }` indicating where the selection starts and ends.
18 | 
19 | # `sell(el, p)`
20 | 
21 | Sets text selection on element `el` to a range `p`, like the ones returned from `sell(el)`. Note that you can set either `start` or `end` to the special `'end'` value, in which case `el.value.length` will be used.
22 |
