# Fungi open-source packages and APIs

> Open-source packages for Agents, interfaces, content tools and games.

These are the packages we use to build Fungi. Use them on their own to run
Agents, build interfaces, work with content, or make games. The code is open
source under the MIT license, so you can use it in your own projects, change it,
and share it. Art Library also includes assets released under CC0.

Read [What's new](/changelog/) for release highlights and fixes.

## Install from npm

Check npm availability before installing a package. Its npm link shows which
versions are published; the package docs explain setup and requirements.

When a published release is available, run `npm install` followed by the full
package name. Packages without a published release are not available through npm
yet.

## Package versions in each Fungi release

Fungi's release number is not a package version. Each package keeps its own
number, so install the version listed for your Fungi release. For example, Fungi
0.29.0 ships Oyster 0.21.4. Install

`@fungi.computer/oyster@0.21.4`, using the Oyster package version
rather than the Fungi release number.

Each linked package has its README, guides and API reference under its own
prefix on this site. Start there for examples, supported runtimes and the
package's public exports.
