-## Note
-
-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.

-### Download Artifacts by ID
-
-The `artifact-ids` input allows downloading artifacts using their unique ID rather than name. This is particularly useful when working with immutable artifacts from `actions/upload-artifact@v4` which assigns a unique ID to each artifact.
-
-```yaml
-steps:
-- uses: actions/download-artifact@v4
-  with:
-    artifact-ids: 12345
-- name: Display structure of downloaded files
-  run: ls -R
-```
-
-Multiple artifacts can be downloaded by providing a comma-separated list of IDs:
-
-```yaml
-steps:
-- uses: actions/download-artifact@v4
-  with:
-    artifact-ids: 12345,67890
-    path: path/to/artifacts
-- name: Display structure of downloaded files
-  run: ls -R path/to/artifacts
-```
-
-This will download multiple artifacts to separate directories (similar to downloading multiple artifacts by name).

 In `v4`, the new `pattern:` input will filter the downloaded Artifacts to match the name specified. The new `merge-multiple:` input will support downloading multiple Artifacts to the same directory. If the files within the Artifacts have the same name, the last writer wins.
-
-## Overwriting an Artifact
-
-In `v3`, the contents of an Artifact were mutable so something like the following was possible:
-
-```yaml
-jobs:
-  upload:
-    runs-on: ubuntu-latest
-    steps:
-      - name: Create a file
-        run: echo "hello world" > my-file.txt
-      - name: Upload Artifact
-        uses: actions/upload-artifact@v3
-        with:
-          name: my-artifact # NOTE: same artifact name
-          path: my-file.txt
-  upload-again:
-    needs: upload
-    runs-on: ubuntu-latest
-    steps:
-      - name: Create a different file
-        run: echo "goodbye world" > my-file.txt
-      - name: Upload Artifact
-        uses: actions/upload-artifact@v3
-        with:
-          name: my-artifact # NOTE: same artifact name
-          path: my-file.txt
-```
-
-The resulting `my-file.txt` in `my-artifact` will have "goodbye world" as the content.
-
-In `v4`, Artifacts are immutable unless deleted. To achieve this same behavior, you can use `overwrite: true` to delete the Artifact before a new one is created:
-
-```diff
-jobs:
-  upload:
-    runs-on: ubuntu-latest
-    steps:
-      - name: Create a file

-    runs-on: ubuntu-latest
-    steps:
-      - name: Create a different file

-          path: my-file.txt
-+         overwrite: true
-```
-
-Note that this will create an _entirely_ new Artifact, with a different ID from the previous.
-
-## Merging multiple artifacts
-
-In `v3`, multiple uploads from multiple jobs could be done to the same Artifact. This would result in a single archive, which could be useful for sending to upstream systems outside of Actions via API or UI downloads.
-
-```yaml
-jobs:
-  upload:
-    strategy:
-      matrix:
-        runs-on: [ubuntu-latest, macos-latest, windows-latest]
-    runs-on: ${{ matrix.runs-on }}
-    steps:
-      - name: Create a File

-        with:
-          name: all-my-files # NOTE: same artifact name
-          path: file-${{ matrix.runs-on }}.txt
-```
-
-The single `all-my-files` artifact would contain the following:
-
-```
-.
-  ∟ file-ubuntu-latest.txt
-  ∟ file-macos-latest.txt
-  ∟ file-windows-latest.txt
-```
-
-To achieve the same in `v4` you can change it like so:
-
-```diff
-jobs:
-  upload:
-    strategy:
-      matrix:
-        runs-on: [ubuntu-latest, macos-latest, windows-latest]
-    runs-on: ${{ matrix.runs-on }}
-    steps:
-      - name: Create a File
-        run: echo "hello from ${{ matrix.runs-on }}" > file-${{ matrix.runs-on }}.txt
-      - name: Upload Artifact
--       uses: actions/upload-artifact@v3
-+       uses: actions/upload-artifact@v4
-        with:
--         name: all-my-files
-+         name: my-artifact-${{ matrix.runs-on }}
-          path: file-${{ matrix.runs-on }}.txt
-+ merge:
-+   runs-on: ubuntu-latest
-+   needs: upload
-+   steps:
-+     - name: Merge Artifacts
-+       uses: actions/upload-artifact/merge@v4
-+       with:
-+         name: all-my-files
-+         pattern: my-artifact-*
-```
-
-Note that this will download all artifacts to a temporary directory and reupload them as a single artifact. For more information on inputs and other use cases for `actions/upload-artifact/merge@v4`, see [the action documentation](https://github.com/actions/upload-artifact/blob/main/merge/README.md).
-
-## Working with Immutable Artifacts
-
-In `v4`, artifacts are immutable by default and each artifact gets a unique ID when uploaded. When an artifact with the same name is uploaded again (with or without `overwrite: true`), it gets a new artifact ID.
-
-To take advantage of this immutability for security purposes (to avoid potential TOCTOU issues where an artifact might be replaced between upload and download), the new `artifact-ids` input allows you to download artifacts by their specific ID rather than by name:
-
-```yaml
-jobs:
-  upload:
-    runs-on: ubuntu-latest
-
-    # Make the artifact ID available to the download job
-    outputs:
-      artifact-id: ${{ steps.upload-step.outputs.artifact-id }}
-
-    steps:
-      - name: Create a file
-        run: echo "hello world" > my-file.txt
-      - name: Upload Artifact
-        id: upload-step
-        uses: actions/upload-artifact@v4
-        with:
-          name: my-artifact
-          path: my-file.txt
-      # The upload step outputs the artifact ID
-      - name: Print Artifact ID
-        run: echo "Artifact ID is ${{ steps.upload-step.outputs.artifact-id }}"
-
-  download:
-    needs: upload
-
-    runs-on: ubuntu-latest
-
-    steps:
-      - name: Download Artifact by ID
-        uses: actions/download-artifact@v4
-        with:
-          # Use the artifact ID directly, not the name, to ensure you get exactly the artifact you expect
-          artifact-ids: ${{ needs.upload.outputs.artifact-id }}
-```
-
-This approach provides stronger guarantees about which artifact version you're downloading compared to using just the artifact name.
