# Piik Documentation

[About Piik](../README.md) · [中文介绍](../README.zh-CN.md) · [中文上手指南](./guide/getting-started.zh-CN.md)

For using Piik, troubleshooting or self-hosting, start with the
[reader documentation](./guide/README.md) · [中文文档中心](./guide/README.zh-CN.md).
This page also indexes developer and maintainer references.

## Run from source

You can try the Browser application locally with Node from
[.node-version](../.node-version), npm from
[package.json](../package.json), and Go 1.26 from [go.mod](../go.mod).
Run these commands from the repository root.

Start the web UI:

```sh
npm ci
npm run dev
```

In a second terminal, start the server. For a POSIX shell:

```sh
PORT=8788 PUBLIC_BASE_URL=http://localhost:8787 go run ./cmd/piik-server
```

Or in PowerShell:

```powershell
$env:PORT = '8788'
$env:PUBLIC_BASE_URL = 'http://localhost:8787'
go build -o build/dev/piik-server.exe ./cmd/piik-server
./build/dev/piik-server.exe
```

The fixed Windows executable path avoids repeated firewall prompts from `go run`.
Open [localhost:8787](http://localhost:8787), start sharing, and open the invitation
in another browser tab to try watching. This localhost invitation stays on your
computer; remote invitations need a reachable origin as described in
[configuration](./standards/configuration.md).
Browser capture requires `localhost` or HTTPS.

For the self-contained App, follow [App development](../cmd/piik-app/README.md#development)
and [packaging](../cmd/piik-app/README.md#packaging), including the platform's
native capture requirements.

## Work on Piik

[Contributing](../CONTRIBUTING.md) covers the workflow and choosing focused checks.
The main verification commands are:

```sh
npm run check
npm run check:go
```

Use the [naming and copy guide](./standards/naming.md) for product names,
commands, role labels and Chinese/English voice.
