# Quick Start

This page takes you from a fresh install to your first downloaded file. You will
create the one piece of configuration unshackle insists on, add a streaming
service and a CDM so it can actually fetch and decrypt media, run a basic
`unshackle dl` command, and learn where the finished file lands.

!!! note "Before you start"
    This guide assumes unshackle is already installed and on your `PATH`. If
    `unshackle --help` does not print a help screen, work through
    [Installation](installation.md) first.

## 1. Check your environment

unshackle drives several external tools (FFmpeg, MKVToolNix, shaka-packager, and
others) to decrypt, repack, and mux media. Confirm they are visible before you
download anything:

```shell
unshackle env check
```

This prints a dependency table. The **required** tools (FFmpeg, FFprobe,
MKVToolNix, mkvpropedit, and shaka-packager) must show a green check. Optional
tools such as `dovi_tool` (Dolby Vision) and CCExtractor (closed captions) only
matter for the features that use them.

!!! tip
    The summary line at the bottom reports `installed/total` and lists anything
    required that is still missing, so you know exactly what to install next.

## 2. Create a minimal config

unshackle reads a single YAML file named `unshackle.yaml`. To see where it looks
for that file, and where it *would* accept one if you have not made it yet, run:

```shell
unshackle env info
```

If no config exists, this prints the candidate locations. In search order they are:

1. `unshackle.yaml` inside the unshackle package folder.
2. `unshackle.yaml` in that folder's parent.
3. `unshackle.yaml` in your OS user-config directory
   (`~/.config/unshackle/` on Linux, `%LOCALAPPDATA%\unshackle\` on Windows,
   `~/Library/Application Support/unshackle/` on macOS).

The **first** file that exists wins. Create `unshackle.yaml` in one of those
locations.

### The one key you must set

unshackle refuses to start a download unless it knows how to name the output file.
That means `output_template` is the one setting a first run genuinely requires.
Everything else has a sensible default. A minimal, working config looks like this:

```yaml title="unshackle.yaml"
output_template:
  movies: "{title} ({year}) {quality} {source}"
  series: "{title} S{season}E{episode} {episode_name} {quality} {source}"
```

Each `{variable}` is filled in from the title and the tracks you downloaded. The
full set of valid variables, including `resolution`, `video`, `audio`, `hdr`,
`edition`, `tag`, and more, is documented in [Configuration](configuration-file.md).

!!! note "Spaces or dots?"
    unshackle auto-detects your naming style from the template: if the separators
    between variables are mostly spaces, it uses spaces; if they are mostly dots,
    it produces scene-style `Title.S01E01.1080p` names. Write the template in the
    style you want the filenames to look.

!!! warning "Editing config from the CLI strips comments"
    You can read and set keys with `unshackle cfg` (for example
    `unshackle cfg tag MYGROUP` or `unshackle cfg --list`), but writing a value
    rewrites the file and **removes any comments** it contained. If you keep notes
    in your config, edit the file by hand instead.

## 3. Add a service

The service tag you pass to `dl` (like `EXAMPLE`) maps to a **service module**, a small
plugin that knows how to talk to one streaming platform. unshackle ships without
any bundled services, so you add the one(s) you want.

Services live under the `directories.services` path (run `unshackle env info` to
see where that is). unshackle discovers them by looking for `*/__init__.py`: the
folder name becomes the **service tag**, and the folder must contain a class with
that exact same name.

=== "Local folder"

    Drop a service folder into your services directory. A service tagged `EXAMPLE`
    lives at:

    ```
    <services>/EXAMPLE/__init__.py     # defines a class named EXAMPLE
    ```

    Once the folder is in place, the tag `EXAMPLE` is immediately available to `dl`,
    `search`, and the other service-aware commands.

=== "Git repository"

    `directories.services` may also list git repositories. unshackle clones them
    on first use and keeps them up to date:

    ```yaml title="unshackle.yaml"
    directories:
      services:
        - owner/unshackle-services      # a GitHub owner/repo shorthand
        - /path/to/local/services       # local folders still work too
    ```

    Force a refresh of every configured service repo at any time with:

    ```shell
    unshackle util refresh-services
    ```

!!! info "Where to get services"
    Service modules are kept separate from the core project. Ask in the community
    [Discord](https://discord.gg/mHYyPaCbFK) for where to find the service you
    need. The core repository deliberately does not host them.

## 4. Add a CDM for DRM

Most streaming content is encrypted. To fetch decryption keys, unshackle needs a
**CDM**, a Widevine device (`.wvd`) or a PlayReady device (`.prd`). Register a
Widevine device you already have with:

```shell
unshackle wvd add /path/to/device.wvd
```

This validates the file and moves it into your WVDs directory. Then point services
at it in your config. The `cdm` map is keyed by service tag, with a `default` that
covers everything else:

```yaml title="unshackle.yaml"
cdm:
  default: my_device        # the .wvd file's name, without the extension
  EXAMPLE: my_other_device       # override for a specific service
```

PlayReady works the same way with `.prd` files created and managed by the
[`prd`](configuration-file.md) command. If a title is DRM-free, no CDM is needed.

!!! tip
    Run `unshackle wvd parse my_device` to inspect a device's security level and
    contents, and `unshackle env info` to confirm where WVDs and PRDs are stored.

## 5. Provide authentication

Services that require a login read either **cookies** or **credentials**.

- **Cookies**: export the service's cookies to a Netscape-format text file and
  place it in your cookies directory. unshackle looks for, in order:
  `cookies/{SERVICE}.txt`, then `cookies/{SERVICE}/{profile}.txt`, then
  `cookies/{SERVICE}/default.txt`. So a file at `cookies/EXAMPLE.txt` is picked up
  automatically for the `EXAMPLE` service.

- **Credentials**: store a username and password per service in your config:

    ```yaml title="unshackle.yaml"
    credentials:
      EXAMPLE: "email@example.com:your-password"
    ```

Use the `-p/--profile` flag to switch between multiple accounts for the same
service. Whether a given service needs cookies, credentials, or nothing at all
depends on the service module.

## 6. Find a title (optional)

If you have a URL or ID already, skip this. Otherwise, search the service for a
title and note the `id` it prints, since that is what you feed to `dl`:

```shell
unshackle search EXAMPLE "My Show"
```

You can also list what a service exposes for a given title without downloading:

```shell
unshackle dl --list-titles EXAMPLE 81234567     # show seasons/episodes
unshackle dl --list EXAMPLE 81234567            # show available tracks
```

## 7. Run your first download

A download always has three parts:

```
unshackle dl  <FLAGS>  <SERVICE-TAG>  <TITLE>
```

- **`dl`** carries every quality, language, track, and output flag.
- **`<SERVICE-TAG>`** picks which service to talk to (e.g. `EXAMPLE`).
- **`<TITLE>`** is the URL, ID, or slug the service understands.

A good first command asks for 1080p with English audio and subtitles:

```shell title="Your first download"
unshackle dl -q 1080 -l en EXAMPLE 81234567
```

unshackle will fetch the title, select the tracks matching your flags, acquire
keys through your CDM (and any key vaults), then decrypt, mux, and tag the result.

### Handy first flags

| Flag | Meaning |
|---|---|
| `-q`, `--quality` | Target resolution(s), e.g. `-q 1080` or `-q 1080,720`. Defaults to best available. |
| `-l`, `--lang` | Language(s) for video and audio, e.g. `-l en` or `-l orig,en`. `orig` = the title's original language. |
| `-sl`, `--s-lang` | Subtitle language(s); defaults to `all`. |
| `-v`, `--vcodec` | Video codec, e.g. `-v H.265`. Defaults to any. |
| `-r`, `--range` | Dynamic range, e.g. `-r HDR10` or `-r DV`. Defaults to `SDR`. |
| `-w`, `--wanted` | Which episodes, e.g. `-w S01` or `-w S01E01-S01E03`. |
| `-o`, `--output` | Override the output directory for this run. |
| `--list` | List the tracks that would be downloaded, then stop. |

!!! example "A few realistic variations"
    ```shell
    # A whole first season in the best available quality
    unshackle dl -w S01 EXAMPLE 81234567

    # 2160p HDR10 with the original-language audio plus English subtitles
    unshackle dl -q 2160 -r HDR10 -l orig -sl en EXAMPLE 81234567

    # Just the newest episode of an ongoing show
    unshackle dl --latest-episode EXAMPLE 81234567
    ```

See [Downloading](../guide/downloading.md) for the complete flag reference, including
codec, bitrate, channel-layout, and track-type selection.

## 8. Where the output lands

By default, finished files are written to the `downloads` directory
(`unshackle env info` shows its exact path; the built-in default is a `downloads`
folder alongside the project). Override it per run with `-o`:

```shell
unshackle dl -q 1080 -o /mnt/media/incoming EXAMPLE 81234567
```

- **Movies** are written as a single `.mkv` file named from your `movies` template.
- **TV episodes** are grouped into a per-show / per-season folder (from your
  `series` template) unless you pass `--no-folder`.
- The filename is built from your `output_template`, and IMDb/TMDB IDs are added to
  the file's metadata tags when available.

To change the default output location permanently, set it in your config:

```yaml title="unshackle.yaml"
directories:
  downloads: /mnt/media/incoming
```

## Where to go next

- **[Downloading](../guide/downloading.md)**. The full `dl` command: quality, codecs,
  languages, track selection, hybrid Dolby Vision, and output control.
- **[Configuration](configuration-file.md)**. Every `unshackle.yaml` key, plus
  directories, key vaults, proxies, and naming templates.
- **[REST API](../dev/rest-api/index.md)**. Run the `serve` server to drive downloads over
  HTTP.

!!! tip "You are never far from help"
    `unshackle --help`, `unshackle dl --help`, and `unshackle <command> --help`
    list every option with its default. When in doubt, add `--list` to a `dl`
    command to preview what it would do before it downloads anything.
