## Get Involved
There is a lot to do! If you are interested in getting involved, here's how you can start:
1. Check out our [contributor guide](./guides/contributor) to learn about our contribution process.
2. Join our [Slack](#slack) and attend our [community meetings](#calendar).
3. If you're interested in contributing to a specific part of the project, join the appropriate [Special Interest Group (SIG)](#special-interest-groups).
Details for all of these items are below. We are a friendly, collaborative group and look forward to working together!
## Governing Bodies
* Governance Committee (GC): [Charter](./governance-charter.md), [Members](./community-members.md#governance-committee)
* Technical Committee (TC): [Charter](./tech-committee-charter.md), [Members](./community-members.md#technical-committee)
Both committees meet regularly, and the respective meeting notes are publicly available in the [GC meeting notes](https://docs.google.com/document/d/1-23Sf7-xZK3OL5Ogv2pK0NP9YotlSa0PKU9bvvtQwp8) and the [TC meeting notes](https://docs.google.com/document/d/1hOHPCu5TGenqTeWPB9qQB_qd33uITZBcvK1FnWxYJAw) Google Docs. The Governance Committee meetings are also recorded.
If you want to check out the recordings, head to the [meeting recordings](https://docs.google.com/spreadsheets/d/1SYKfjYhZdm2Wh2Cl6KVQalKg_m4NhTPZqq-8SzEVO6s).
## Areas of Interest
Technical committee members, maintainers, and approvers are encouraged
to list their [areas of interest in this
document](areas-of-interest.md) to help community members find
interested parties and form new special interest groups.
## Communication
### Slack
For those who are brand new to OpenTelemetry and want to chat or get redirected to the appropriate place for a specific question, feel free to join [the CNCF OpenTelemetry Slack channel](https://cloud-native.slack.com/archives/CJFCJHG4Q). If you are new, you can create a CNCF Slack account [here](https://slack.cncf.io/).
### Calendar
The shared community calendar contains all public OpenTelemetry meetings,
including weekly SIG meetings, monthly community meetings, etc. You
can access it via:
* [Web](https://calendar.google.com/calendar/embed?src=c_2bf73e3b6b530da4babd444e72b76a6ad893a5c3f43cf40467abc7a9a897f977%40group.calendar.google.com)
* [Google
Calendar](https://calendar.google.com/calendar?cid=c_2bf73e3b6b530da4babd444e72b76a6ad893a5c3f43cf40467abc7a9a897f977@group.calendar.google.com)
* [iCalendar](https://calendar.google.com/calendar/ical/c_2bf73e3b6b530da4babd444e72b76a6ad893a5c3f43cf40467abc7a9a897f977%40group.calendar.google.com/public/basic.ics)
The best way to subscribe to specific OpenTelemetry meeting series is to join the associated
[calendar-...@opentelemetry.io meeting invite groups below](#special-interest-groups).
This will invite you to the specific OpenTelemetry meetings, correctly block time for
accepted meetings, and keep your calendar in sync with new and updated events.
Alternatively, if you wish to subscribe to all OpenTelemetry meeting series you can subscribe to [calendar-all@opentelemetry.io](https://groups.google.com/a/opentelemetry.io/g/calendar-all).
### Mailing Lists
List Name | Signup | Membership | Write Permissions | Read Permissions | Notes
----------------------------------------------|-----------------------------------------------------------------|------------------------|-------------------|------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
cncf-opentelemetry-community@lists.cncf.io | [Here](https://lists.cncf.io/g/cncf-opentelemetry-community) | anyone | GC and TC | anyone | <details><summary>Notes</summary>The community mailing list is for anybody who wants to monitor the latest news from the project. It is used to send updates on community meetings and announcements about new projects and SIGs. There is minimal moderation for a new user to reduce spam, and new users are approved after one post.</details>
cncf-opentelemetry-contributors@lists.cncf.io | [Here](https://lists.cncf.io/g/cncf-opentelemetry-contributors) | anyone | anyone | anyone | <details><summary>Notes</summary>The discussions mailing list is for anyone who is interested in contributing to OpenTelemetry or has questions (related to the contribution, technical issues,etc) they’d like to discuss. Will be used to announce updates related to how the project is being developed and ask general contribution questions related to the contribution processes. No approval is required to join.</details>
cncf-opentelemetry-tc@lists.cncf.io | N/A | TC | anyone | members | <details><summary>Notes</summary>Used by the OpenTelemetry Technical Committee for internal communication. This mailing list should be used sparingly as we strive to keep all communication public. It only should be used to contact the Technical Committee with questions that cannot be discussed publicly on GitHub, GitHub discussions, or the community or contributors' mailing lists.</details>
cncf-opentelemetry-governance@lists.cncf.io | N/A | GC | anyone | members | <details><summary>Notes</summary>Used by the OpenTelemetry GC for internal communication. Additionally, contact the GC for questions that cannot be discussed publicly on GitHub, GitHub discussions, or other mailing lists. For instance, members could use this for issues related to improper applications of our community membership guidance.</details>
cncf-opentelemetry-comms@lists.cncf.io | [Here](https://lists.cncf.io/g/cncf-opentelemetry-comms) | GC and open for anyone | anyone | anyone | <details><summary>Notes</summary>Mailing list to notify and request reviews of upcoming announcements, or request a post on the OpenTelemetry Twitter account or other public channels.</details>
### Media
For PR & Marketing inquiries, please contact [pr@cncf.io](mailto:pr@cncf.io).
## License
All OpenTelemetry projects are shipped under the permissive Apache 2.0 license
as CNCF IP Policy
[dictates](https://github.com/cncf/foundation/blob/master/charter.md#11-ip-policy).
This [blog post](https://www.cncf.io/blog/2017/02/01/cncf-recommends-aslv2/)
explains the reasoning behind choosing this license.
## Logos and Brand Guide
The OpenTelemetry logos and brand guide can be found in the [CNCF artwork
repository](https://github.com/cncf/artwork/tree/master/projects/opentelemetry). In addition, a [Google Slides template](https://docs.google.com/presentation/d/1Neab3OZ3c-m5kOE37iZXEVpK4Pjj6xGTJEUuUzLQJvk/edit?usp=sharing) is also available.
## How to
- [Get access and manage meetings](docs/how-to-handle-public-calendar.md).
- [Request GitHub extension or create a bit](docs/using-github-extensions.md).
- [Configure new repository](docs/how-to-configure-new-repository.md): listing settings TC members set when creating the new repository.
## Special Interest Groups
We organize the community into Special Interest Groups (SIGs) to
improve our workflow and more efficiently manage a community project. While meetings are expected to happen regularly, they are subject to contributors' availability and may be rescheduled or changed at time. Check our [public calendar](https://github.com/open-telemetry/community#calendar) and SIG-specific GitHub discussions for meeting changes and cancellations. All meetings happen over Zoom, have a meeting notes document, and are recorded and [available on Zoom cloud](https://docs.google.com/spreadsheets/d/1SYKfjYhZdm2Wh2Cl6KVQalKg_m4NhTPZqq-8SzEVO6s).
Please do not hesitate to contact SIG owners if the proposed time of the
meeting or tools used is unavailable for you. For instance, it is a good
practice to alternate morning/evening meetings once SIG has representatives
from 3 largely distinct timezones. The best way to report it and suggest an
alternative is to file an issue on this repository or discuss it in
SIG-specific GitHub discussions.
> [!NOTE]
> The meeting times in the tables below are given in 24-hour notation.
> Meetings are either in Pacific Time (PT), with Daylight Saving Time, or UTC+8, without Daylight Saving Time.
