# 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

```xml

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
```

- select any channel from [channels/unsorted.m3u](https://github.com/iptv-org/iptv/blob/master/channels/unsorted.m3u)

| `LANGUAGE` | Channel language. The name of the language must conform to the standard [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).

| `STREAM_TIME_SHIFT` | Must be specified if the channel is broadcast with a shift in time relative to the main stream. Should only contain a number and a sign. (optional) |
| `ALTERNATIVE_NAME` | Can be used to specify a short name or name in another language. May contain any characters except round and square brackets. (optional) |
