## Installation
|
||
|
|
|
||
|
|
The easiest way is to keep `karma-detect-browsers` as a devDependency in your `package.json`.
|
||
|
|
```json
|
||
|
|
{
|
||
|
|
"devDependencies": {
|
||
|
|
"karma": "^0.13",
|
||
|
|
"karma-detect-browsers": "^2.0"
|
||
|
|
}
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
You can simply do it by:
|
||
|
|
```bash
|
||
|
|
npm install karma-detect-browsers --save-dev
|
||
|
|
```
|
||
|
|
|
||
|
|
