## The problem
- It works on my computer
- "command not found"
- what version of "command" are you running?
- what version of "different command" are you running?
- do you have "insert obscure android sdk version"?
- every github issue reporting template ever:
**Please mention other relevant information such as the browser version, Node.js version, Operating System and programming language.**
## This solution
- Gather all of this information in one spot, quickly, and painlessly.

To use as a CLI tool, install this package globally:
```sh
npm install -g envinfo || yarn global add envinfo

```javascript
import envinfo from 'envinfo';
console.log(
envinfo.run(
{
System: ['OS', 'CPU'],
Binaries: ['Node', 'Yarn', 'npm'],
Browsers: ['Chrome', 'Firefox', 'Safari'],
npmPackages: ['styled-components', 'babel-plugin-styled-components'],
},
{ json: true }
)
);
```
returns:
```
{

}
}
```
All of envinfo's helpers are also exported for use. You can use envinfo as a whole, or just the parts that you need, like this:
```javascript
import { helpers } from 'envinfo';
const OS = helpers.getOperatingSystemInfo();
const docker = helpers.getDockerVersion();
console.log({ OS, docker });
```
```
{
OS: 'macOS High Sierra 10.13'
docker: '17.12.0-ce, build c97c6d6'
}
```
