+## Contributing
 
-Thank you for your interest in this GitHub repo, however, right now we are not taking contributions. 
-
-We continue to focus our resources on strategic areas that help our customers be successful while making developers' lives easier. While GitHub Actions remains a key part of this vision, we are allocating resources towards other areas of Actions and are not taking contributions to this repository at this time. The GitHub public roadmap is the best place to follow along for any updates on features we’re working on and what stage they’re in.
-
-We are taking the following steps to better direct requests related to GitHub Actions, including:
-
-1. We will be directing questions and support requests to our [Community Discussions area](https://github.com/orgs/community/discussions/categories/actions)
-
-2. High Priority bugs can be reported through Community Discussions or you can report these to our support team https://support.github.com/contact/bug-report.
-
-3. Security Issues should be handled as per our [security.md](SECURITY.md).
-
-We will still provide security updates for this project and fix major breaking changes during this time.
-
-You are welcome to still raise bugs in this repo.

-# Releasing Packages
-
-Packages are published to npm via the **Publish NPM** workflow ([`.github/workflows/releases.yml`](../.github/workflows/releases.yml)). The workflow is triggered manually through `workflow_dispatch` from the GitHub Actions UI.
-
-## How it works
-
-The workflow has two jobs:
-
-1. **test** — Checks out the specified branch, installs dependencies, bootstraps the monorepo, builds all packages, runs tests, then packs the target package into a `.tgz` archive and uploads it as a workflow artifact.
-2. **publish** — Downloads the packed artifact and publishes it to npm with `--provenance` (OIDC-based). Sends a Slack notification on success or failure. Requires the `npm-publish` environment.
-
-## Inputs
-
-| Input | Type | Required | Default | Description |
-|---|---|---|---|---|
-| `package` | choice | **yes** | — | Which package to release. One of: `artifact`, `attest`, `cache`, `core`, `exec`, `github`, `glob`, `http-client`, `io`, `tool-cache`. |
-| `branch` | string | no | `main` | The branch to check out and release from. |
-| `npm-tag` | string | no | `latest` | The npm dist-tag to publish under. See [Dist-tags](#dist-tags) below. |
-| `test-all` | boolean | no | `false` | When `false`, only tests for the selected package are run. Set to `true` to run the full test suite across all packages. |
-
-## Dist-tags
-
-npm dist-tags control which version users get when they `npm install @actions/<package>` (or `@<tag>`).
-
-> **Important:** npm dist-tags **cannot** be valid semver strings. Values like `5.0.0` or `1.2.3` will be rejected by npm. Use a descriptive name instead.
-
-- **`latest`** — The default tag. This is what users get with a plain `npm install`. Should only be used for releases from `main`.
-- **Custom tags** (e.g. `v1-longlived`) — Used for releases from long-lived or experimental branches.
-
-Examples of **valid** dist-tags: `latest`, `next`, `beta`, `v1-longlived`
-Examples of **invalid** dist-tags: `5.0.0`, `1.2.3`, `6.0.0-rc.1` (these are semver and will be rejected)
-
-| ![Screenshot showcasing the npm distribution tags](assets/npm-dist-tags.png) |
-|---|
-| npm distribution tags |
-
-### Safety guard
-
-The workflow **blocks** publishing with the `latest` dist-tag from any branch other than `main`. This prevents accidentally overwriting `latest` with a version from an older or experimental branch. If you're releasing from a non-main branch, use the package's major version as the tag (e.g. `v5`).
-
-## Examples
-
-### Standard release from main
-
-Use default inputs — just pick the package:
-
-| Input | Value |
-|---|---|
-| `package` | `core` |
-| `branch` | `main` (default) |
-| `npm-tag` | `latest` (default) |
-| `test-all` | `false` (default) |
-
-This publishes the version in `packages/core/package.json` on `main` as `@actions/core@latest`.
-
-### Patch release from a long-lived branch
-
-| Input | Value |
-|---|---|
-| `package` | `artifact` |
-| `branch` | `releases/v5` |
-| `npm-tag` | `v5` |
-| `test-all` | `false` (default) |
-
-This publishes the version in `packages/artifact/package.json` on the `releases/v5` branch under the `v5` dist-tag. The `latest` tag remains untouched.
-
-### Release with full test suite
-
-| Input | Value |
-|---|---|
-| `package` | `cache` |
-| `branch` | `main` (default) |
-| `npm-tag` | `latest` (default) |
-| `test-all` | `true` |
-
-Same as a standard release, but runs tests for all packages before publishing.
-
-## Prerequisites
-
-- You must have permission to trigger workflows on this repository.
-- The `npm-publish` environment must be configured with npm credentials and OIDC.
-- The `SLACK` secret must be set for Slack notifications to work.

 # @actions/artifact Releases
 
-## 6.2.1
-
-- Support the RFC 5987 `filename*` field in the `content-disposition` header. This allows us to correctly download files and artifacts with Chinese/Japanese/Korean (among other) characters in their name.
-
-## 6.2.0
-
-- Support uploading single un-archived files (not zipped). Direct uploads are only supported for artifacts version 7+ (based on the major version of `actions/upload-artifact`). Callers must pass the `skipArchive` option to `uploadArtifact`. Only single files can be uploaded at a time right now. Default behavior should remain unchanged if `skipArchive = false`. When `skipArchive = true`, the name of the file is used as the name of the artifact for consistency with the downloads: you upload `artifact.txt`, you download `artifact.txt`.
-
-## 6.1.0
-
-- Support downloading non-zip artifacts. Zipped artifacts will be decompressed automatically (with an optional override). Un-zipped artifacts will be downloaded as-is.
-
-## 6.0.0
-
-- **Breaking change**: Package is now ESM-only
-  - CommonJS consumers must use dynamic `import()` instead of `require()`
