 # API Reference
 
+## $.sync 
+Zx provides both synchronous and asynchronous command executions, returns [`ProcessOutput`](./process-output) or [`ProcessPromise`](./process-promise) respectively.
+
+```js
+const list = await $`ls -la`
+const dir = $.sync`pwd`
+```
+
+## $({...})
+
+`$` object holds the default zx [configuration](./configuration), which is used for all execution. To specify a custom preset use `$` as factory:
+
+```js
+const $$ = $({
+  verbose: false,
+  env: {NODE_ENV: 'production'},
+})
+
+const env = await $$`node -e 'console.log(process.env.NODE_ENV)'`
+const pwd = $$.sync`pwd`
+const hello = $({quiet: true})`echo "Hello!"`
+```
+
+### $({input})
+
+The input option passes the specified `stdin` to the command.
+
+```js
+const p1 = $({ input: 'foo' })`cat`
+const p2 = $({ input: Readable.from('bar') })`cat`
+const p3 = $({ input: Buffer.from('baz') })`cat`
+const p4 = $({ input: p3 })`cat`
+const p5 = $({ input: await p3 })`cat`
+```
+
+### $({signal})
+
+The signal option makes the process abortable.
+
+```js
+const {signal} = new AbortController()
+const p = $({ signal })`sleep 9999`
+
+setTimeout(() => signal.abort('reason'), 1000)
+```
+
+### $({timeout})
+
+The timeout option makes the process autokillable after the specified delay.
+
+```js
+const p = $({timeout: '1s'})`sleep 999`
+```
+
+The full options list:
+```ts
+interface Options {
+  cwd:            string
+  ac:             AbortController
+  signal:         AbortSignal
+  input:          string | Buffer | Readable | ProcessOutput | ProcessPromise

+# Contribution Guide
+
+zx is a fully [open-source project](https://github.com/google/zx), which is developing by the community for the community. 
+We welcome contributions of any kind, including but not limited to:
+* Bug reports
+* Feature requests
+* Code contributions
+* Documentation improvements
+* Discussions
+
+## Community Guidelines
+
+This project follows [Google's Open Source Community Guidelines](https://opensource.google/conduct/).
+In short: all contributors are treated with respect and fairness.
+
+## Contributor License Agreement

+part of the project. Head over to <https://cla.developers.google.com/> to see
+your current agreements on file or to sign a new one.
+
+You generally only need to submit a CLA once, so if you've already submitted one
+(even if it was for a different project), you probably don't need to do it
+again.
+
+## How to Contribute
+Before proposing changes, look for similar ones in the project's [issues](https://github.com/google/zx/issues) and [pull requests](https://github.com/google/zx/pulls). If you can't decide, create a new [discussion](https://github.com/google/zx/discussions) topic, and we will help you figure it out. When ready to move on:
+* Prepare your development environment.
+  * Ensure you have Node.js 20+ installed.
+  * Bash is essential for running zx scripts. Linux and macOS users usually have it installed by default. Consider using [Windows Subsystem for Linux](https://docs.microsoft.com/en-us/windows/wsl/install) or [Git Bash](https://git-scm.com/downloads) if you are on Windows.
+* Fork [the repository](https://github.com/google/zx).
+* Create a new branch.
+* Make your changes.
+  * If you are adding a new feature, please include additional tests. The coverage threshold is 98%.
+  * Create a [conventional-commits](https://www.conventionalcommits.org/en/v1.0.0/) compliant messages.
+* Ensure that everything is working:
+  * `npm run fmt` to format your code.
+  * `npm run cov` to run the tests.
+* Push the changes to your fork.
+* Create a pull request.
+  * Describe your changes in detail.
+  * Reference any related issues if applicable.
+
+## Code Reviews
+

+# Migration from v7 to v8
+
+[v8.0.0 release](https://github.com/google/zx/releases/tag/8.0.0) brought many features, improvements and fixes, but also has introduced a few breaking changes.
+
+1. `$.verbose` is set to `false` by default, but errors are still printed to `stderr`. Set `$.quiet = true` to suppress any output.
+```js
+$.verbose = true // everything works like in v7
+
+$.quiet = true   // to completely turn off logging
+```
+
+2. `ssh` API was dropped. Install [webpod](https://github.com/webpod/webpod) package instead.
+```js
+// import {ssh} from 'zx' ↓
+import {ssh} from 'webpod'
+
+const remote = ssh('user@host')
+await remote`echo foo`
+```
+
+3. zx is not looking for `PowerShell` anymore, on Windows by default. If you still need it, use the `usePowerShell` helper to enable:
+
+```js
+import { usePowerShell, useBash } from 'zx'
+
+usePowerShell() // to enable powershell
+useBash()       // switch to bash, the default
+```
+
+To look for modern [PowerShell v7+](https://github.com/google/zx/pull/790), invoke `usePwsh()` helper instead:
+
+```js
+import { usePwsh } from 'zx'
+
+usePwsh()
+```
+
+4. Process cwd synchronization between `$` invocations is now disabled by default. This functionality is provided via an async hook and can now be controlled directly.
+
+```js
+import { syncProcessCwd } from 'zx'
+
+syncProcessCwd() // restores legacy v7 behavior
+```
