Node.js
=======
[![Gitter](https://badges.gitter.im/Join Chat.svg)](https://gitter.im/nodejs/node?utm_source=badge&utm_medium=badge&utm_campaign=pr-badge&utm_content=badge)
The Node.js project is supported by the
[Node.js Foundation](https://nodejs.org/en/foundation/). Contributions,
policies and releases are managed under an
[open governance model](./GOVERNANCE.md). We are also bound by a
[Code of Conduct](./CODE_OF_CONDUCT.md).
If you need help using or installing Node.js, please use the
[nodejs/help](https://github.com/nodejs/help) issue tracker.
## Release Types
The Node.js project maintains multiple types of releases:
* **Stable**: Released from active development branches of this repository,
versioned by [SemVer](http://semver.org/) and signed by a member of the
[Release Team](#release-team).
Code for Stable releases is organized in this repository by major version
number, For example: [v4.x](https://github.com/nodejs/node/tree/v4.x).
The major version number of Stable releases will increment every 6 months
allowing for breaking changes to be introduced. This happens in April and
October every year. Stable release lines beginning in October each year have
a maximum support life of 8 months. Stable release lines beginning in April
each year will convert to LTS (see below) after 6 months and receive further
support for 30 months.
* **LTS**: Releases that receive Long-term Support, with a focus on stability
and security. Every second Stable release line (major version) will become an
LTS line and receive 18 months of _Active LTS_ support and a further 12
months of _Maintenance_. LTS release lines are given alphabetically
ordered codenames, begining with v4 Argon. LTS releases are less frequent
and will attempt to maintain consistent major and minor version numbers,
only incrementing patch version numbers. There are no breaking changes or
feature additions, except in some special circumstances. More information
can be found in the [LTS README](https://github.com/nodejs/LTS/).
* **Nightly**: Versions of code in this repository on the current Stable
branch, automatically built every 24-hours where changes exist. Use with
caution.
## Download
Binaries, installers, and source tarballs are available at
<https://nodejs.org>.
**Stable** and **LTS** releases are available at
<https://nodejs.org/download/release/>, listed under their version strings.
The [latest](https://nodejs.org/download/release/latest/) directory is an
alias for the latest Stable release. The latest LTS release from an LTS
line is available in the form: latest-lts-_codename_. For example:
<https://nodejs.org/download/release/latest-lts-argon>
**Nightly** builds are available at
<https://nodejs.org/download/nightly/>, listed under their version
string which includes their date (in UTC time) and the commit SHA at
the HEAD of the release.
**API documentation** is available in each release and nightly
directory under _docs_. <https://nodejs.org/api/> points to the API
documentation of the latest stable version.
### Verifying Binaries
Stable, LTS and Nightly download directories all contain a *SHASUM256.txt*
file that lists the SHA checksums for each file available for
download. To check that a downloaded file matches the checksum, run
it through `sha256sum` with a command such as:
```
$ grep node-vx.y.z.tar.gz SHASUMS256.txt | sha256sum -c -
```
_(Where "node-vx.y.z.tar.gz" is the name of the file you have
downloaded)_
Additionally, Stable and LTS releases (not Nightlies) have GPG signed
copies of SHASUM256.txt files available as SHASUM256.txt.asc. You can use
`gpg` to verify that the file has not been tampered with.
To verify a SHASUM256.txt.asc, you will first need to import all of
the GPG keys of individuals authorized to create releases. They are
listed at the bottom of this README under [Release Team](#release-team).
Use a command such as this to import the keys:
```
$ gpg --keyserver pool.sks-keyservers.net \
--recv-keys DD8F2338BAE7501E3DD5AC78C273792F7D83545D
```
_(See the bottom of this README for a full script to import active
release keys)_
You can then use `gpg --verify SHASUMS256.txt.asc` to verify that the
file has been signed by an authorized member of the Node.js team.
Once verified, use the SHASUMS256.txt.asc file to get the checksum for
the binary verification command above.

## Security
All security bugs in node.js are taken seriously and should be reported by
emailing security@nodejs.org. This will be delivered to a subset of the project
team who handle security issues. Please don't disclose security bugs
public until they have been handled by the security team.
Your email will be acknowledged within 24 hours, and you’ll receive a more
detailed response to your email within 48 hours indicating the next steps in
handling your report.
## Current Project Team Members
The Node.js project team comprises a group of core collaborators and a sub-group
that forms the _Technical Steering Committee_ (TSC) which governs the project. For more
