# Contributing Guide

Before submitting your contribution, please make sure to take a moment and read through the following guidelines:

- [Issue Reporting Guidelines](#issue-reporting-guidelines)
- [Pull Request Guidelines](#pull-request-guidelines)
- [Channel Description Scheme](#channel-description-scheme)
- [Project Structure](#project-structure)

## Issue Reporting Guidelines

### Request a Channel

To request a channel, create an [issue](https://github.com/iptv-org/iptv/issues/new?assignees=&labels=channel+request&template=------channel-request.md&title=Add%3A+xxx) and complete all details requested. (**IMPORTANT:** the issue should contain a request for only one channel, otherwise it will be closed immediately). Understand that our community of volunteers will try to help you, but if a public link cannot be found, there is little we can do.

### Report a Broken Stream

To report a broadcast that is not working, create an [issue](https://github.com/iptv-org/iptv/issues/new?assignees=&labels=broken+stream&template=----broken-stream.md&title=Fix%3A+xxx) with a description of the channel (**IMPORTANT:** an issue should contain a report for only one channel, otherwise it will be closed immediately).

### Request Channel Removal

Publish your DMCA notice somewhere and send us a link to it through this [form](https://github.com/iptv-org/iptv/issues/new?assignees=&labels=DMCA&template=--remove-channel.md&title=Remove%3A+xxx).

## Pull Request Guidelines

### Add or Replace a Stream

If you would like to replace a broken stream or add a new one, please do the following:

- make sure that the link you want to add works by using a program like [VLC media player](https://www.videolan.org/vlc/index.html)
- check if the channel is working outside your country by using a VPN or use a service like [streamtest.in](https://streamtest.in/)
- if the broadcast is not available outside of a certain country, add the label `[Geo-blocked]` to the end of the channel name
- find out from which country the channel is being broadcasted. This information can usually be found on [lyngsat.com](https://www.lyngsat.com/search.html) or [wikipedia.org](https://www.wikipedia.org/). If you are unable to determine which country the channel belongs to, add the channel onto the `channels/unsorted.m3u` playlist
- find the corresponding [ISO_3166-2 code](https://en.wikipedia.org/wiki/ISO_3166-2) for the country
- open the `/channels` folder and find the file that has the same code in its name and open it
- if broken, find the broken link in this file and replace it with working one
- if new, at the very end of this file add a link to the channel with a description
- commit all changes and send a pull request

### Add a Category to a Channel

- select a channel that does not have a category specified
- find the file that contains the channel. You can use a [GitHub Search](https://github.com/search/advanced?q=CHANNEL_NAME+repo%3Aiptv-org%2Fiptv+path%3A%2Fchannels&type=Code) to do this
- find the desired channel in this file
- specify the appropriate category in the `group-title` attribute. A complete list of supported categories can be found [here](https://github.com/iptv-org/iptv/blob/master/.readme/supported-categories.md)
- commit all changes and send a pull request

### Add a Language to a Channel

- select a channel that does not have a language specified
- find the file that contains the channel. You can use a [GitHub Search](https://github.com/search/advanced?q=CHANNEL_NAME+repo%3Aiptv-org%2Fiptv+path%3A%2Fchannels&type=Code) to do this.
- find the desired channel in this file
- specify the appropriate language in the `tvg-language` attribute. The name of the language must comply with the [ISO 639-3](https://iso639-3.sil.org/code_tables/639/data?title=&field_iso639_cd_st_mmbrshp_639_1_tid=94671&name_3=&field_iso639_element_scope_tid=All&field_iso639_language_type_tid=51&items_per_page=500) standard.
- commit all changes and send a pull request

If a channel is broadcasted in several languages at once, you can specify them all through a semicolon, like this:

```xml
#EXTINF:-1 tvg-language="English;Chinese",CCTV
http://example.com/cctv.m3u8
```

### Add a Country to a Channel

- select a channel that does not have a country specified
- find out in which country the channel is broadcast. This information can usually be found in the channel description on Wikipedia.
- find the corresponding [ISO_3166-2 code](https://en.wikipedia.org/wiki/ISO_3166-2) corresponding to the country
- find the file that contains the channel. You can use a [GitHub Search](https://github.com/search/advanced?q=CHANNEL_NAME+repo%3Aiptv-org%2Fiptv+path%3A%2Fchannels&type=Code) to do this.
- find the desired channel in this file
- paste the country ISO_3166-2 code into `tvg-country` attribute of the channel description
- commit all changes and send a pull request

If a channel is broadcasted in several countries at once, you can specify them all through a semicolon, like this:

```xml
#EXTINF:-1 tvg-country="US;CA",CNN
http://example.com/cnn.m3u8
```

If a channel is broadcast for an entire region, you can use one of the [supported region code](https://github.com/iptv-org/iptv/blob/master/.readme/supported-region-codes.md) to avoid listing all countries. In this case the channel will be added to the playlists of all countries from that region.

In case the channel is broadcast worldwide you can use the code `INT`:

```xml
#EXTINF:-1 tvg-country="INT",CNN
http://example.com/cnn.m3u8
```

### Sort channels from `channels/unsorted.m3u`

- select any channel from [channels/unsorted.m3u](https://github.com/iptv-org/iptv/blob/master/channels/unsorted.m3u)
- find out the full name of the channel and from which country it is being broadcasted. This information can usually be found on [lyngsat.com](https://www.lyngsat.com/search.html) or [wikipedia.org](https://www.wikipedia.org/)
- update the channel name if necessary
- find the corresponding [ISO_3166-2 code](https://en.wikipedia.org/wiki/ISO_3166-2) for the country
- open the `channels/` folder and find a file with the same name as the country code
- at the very end of this file add a link to the channel with a description
