 Review carefully the provided examples and the working [tests](./test).
 
-### [.exec](src/index.js#L47)
-> Same as [execa][]'s main export [here](https://github.com/sindresorhus/execa#execafile-arguments-options) As state there, think of it as mix of `child_process`'s `.execFile` and `.spawn`. It is pretty similar to the `.shell` method too, but only visually because it does not uses the system's shell.
-
-> It also can accept array of multiple strings of commands that will be
-executed in series.
-
-**Params**
-
-* `cmds` **{string|Array}**: a commands to execute, if array of strings executes them serially    
-* `opts` **{Object}**: directly passed to [execa][] and so to `child_process`    
-* `returns` **{Promise}**: resolved or rejected promises  
-
-**Example**
-
-```js
-const { exec } = require('execa-pro')
-
-async function init () {
-  await exec('echo "hello world"', { stdio: 'inherit' })
-
-  // executes in series
-  await exec([
-    'prettier-eslint --write foobar.js',
-    'eslint --format codeframe foobar.js --fix'
-  ], { stdio: 'inherit', preferLocal: true })
-}
-
-init()
-```
-
-### [.shell](src/index.js#L100)
-> Same as [execa][]'s `.shell` method, but also can accept an array of multiple commands that will be executed in the system's shell, [see its docs](https://github.com/sindresorhus/execa#execashellcommand-options) for more info.
