+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.

+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+## Usage
+
+In the examples below we are also using 3 other actions:
+
+* [`setup-buildx`](https://github.com/docker/setup-buildx-action) action will
+  create and boot a builder using by default the [`docker-container` driver](https://docs.docker.com/build/building/drivers/docker-container/).
+  This is **not required but recommended** using it to be able to build
+  multi-platform images, export cache, etc.
+* [`setup-qemu`](https://github.com/docker/setup-qemu-action) action can be
+  useful if you want to add emulation support with QEMU to be able to build
+  against more platforms. 
+* [`login`](https://github.com/docker/login-action) action will take care to
+  log in against a Docker registry.
+
+### Git context
+
+By default, this action uses the [Git context](https://docs.docker.com/engine/reference/commandline/build/#git-repositories),
+so you don't need to use the [`actions/checkout`](https://github.com/actions/checkout/)
+action to check out the repository as this will be done directly by [BuildKit](https://github.com/moby/buildkit).
+
+The git reference will be based on the [event that triggered your workflow](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows)
+and will result in the following context: `https://github.com/<owner>/<repo>.git#<ref>`.
+
+```yaml
+name: ci
+
+on:
+  push:
+
+jobs:
+  docker:
+    runs-on: ubuntu-latest
+    steps:
+      -
+        name: Login to Docker Hub
+        uses: docker/login-action@v3
+        with:
+          username: ${{ vars.DOCKERHUB_USERNAME }}
+          password: ${{ secrets.DOCKERHUB_TOKEN }}
+      -
+        name: Set up QEMU
+        uses: docker/setup-qemu-action@v3
+      -
+        name: Set up Docker Buildx
+        uses: docker/setup-buildx-action@v3
+      -
+        name: Build and push
+        uses: docker/build-push-action@v6
+        with:
+          push: true
+          tags: user/app:latest
+```
+
+Be careful because **any file mutation in the steps that precede the build step
+will be ignored, including processing of the `.dockerignore` file** since
+the context is based on the Git reference. However, you can use the
+[Path context](#path-context) using the [`context` input](#inputs) alongside
+the [`actions/checkout`](https://github.com/actions/checkout/) action to remove
+this restriction.
+
+Default Git context can also be provided using the [Handlebars template](https://handlebarsjs.com/guide/)
+expression `{{defaultContext}}`. Here we can use it to provide a subdirectory
+to the default Git context:
+
+```yaml
+      -
+        name: Build and push
+        uses: docker/build-push-action@v6
+        with:
+          context: "{{defaultContext}}:mysubdir"
+          push: true
+          tags: user/app:latest
+```
+
+Building from the current repository automatically uses the [GitHub Token](https://docs.github.com/en/actions/security-guides/automatic-token-authentication),
+so it does not need to be passed. If you want to authenticate against another
+private repository, you have to use a [secret](https://docs.docker.com/build/ci/github-actions/secrets)
+named `GIT_AUTH_TOKEN` to be able to authenticate against it with Buildx:
+
+```yaml
+      -
+        name: Build and push
+        uses: docker/build-push-action@v6
+        with:
+          push: true
+          tags: user/app:latest
+          secrets: |
+            GIT_AUTH_TOKEN=${{ secrets.MYTOKEN }}
+```
+
+### Path context
+
+```yaml
+name: ci
+
+on:
+  push:
+
+jobs:
+  docker:
+    runs-on: ubuntu-latest
+    steps:

+        name: Checkout
+        uses: actions/checkout@v4
+      -

+        uses: docker/login-action@v3
+        with:
+          username: ${{ vars.DOCKERHUB_USERNAME }}
+          password: ${{ secrets.DOCKERHUB_TOKEN }}
+      -

+## Summaries
+
+This action generates a [job summary](https://github.blog/2022-05-09-supercharging-github-actions-with-job-summaries/)
+that provides a detailed overview of the build execution. The summary shows an
+overview of all the steps executed during the build, including the build inputs
+and eventual errors.
+
+![build-push-action job summary](./.github/build-push-summary.png)
+
+The summary also includes a link for downloading the build record with
+additional details about the build, including build stats, logs, outputs, and
+more. The build record can be imported to Docker Desktop for inspecting the
+build in greater detail.
+
+> [!WARNING]
+>
+> If you're using the [`actions/download-artifact`](https://github.com/actions/download-artifact)
+> action in your workflow, you need to ignore the build record artifacts
+> if `name` and `pattern` inputs are not specified ([defaults to download all artifacts](https://github.com/actions/download-artifact?tab=readme-ov-file#download-all-artifacts) of the workflow),
+> otherwise the action will fail:
+> ```yaml
+> - uses: actions/download-artifact@v4
+>   with:
+>     pattern: "!*.dockerbuild"
+> ```
+> More info: https://github.com/actions/toolkit/pull/1874
+
+Summaries are enabled by default, but can be disabled with the
+`DOCKER_BUILD_SUMMARY` [environment variable](#environment-variables).

+* [Cannot push to a registry](#cannot-push-to-a-registry)
+  * [BuildKit container logs](#buildkit-container-logs)
+  * [With containerd](#with-containerd)
+* [`repository name must be lowercase`](#repository-name-must-be-lowercase)
+
+## Cannot push to a registry
+
+While pushing to a registry, you may encounter these kinds of issues:
+
+* `failed commit on ref "layer-sha256:...": invalid content digest in response: invalid checksum digest format`
+* `failed commit on ref "layer-sha256:...": no response`
+* `failed commit on ref "manifest-sha256:...": unexpected status: 400 Bad Request`
+* `failed commit on ref "manifest-sha256:...": unexpected status: 401 Unauthorized`
+* `unexpected response: 401 Unauthorized`
+
+These issues are not directly related to this action but are rather linked to
+[Buildx](https://github.com/docker/buildx), [BuildKit](https://github.com/moby/buildkit),
+[containerd](https://github.com/containerd/containerd) or the registry on which
+you're pushing your image. The quality of error message depends on the registry
+and are usually not very informative.
+
+### BuildKit container logs
+
+To help you solve this, you have to [enable debugging in the setup-buildx](https://github.com/docker/setup-buildx-action#buildkit-container-logs)
+action step and attach BuildKit container logs to your issue.
+
+### With containerd
+
+Next you can test pushing with [containerd action](https://github.com/crazy-max/ghaction-setup-containerd)
+using the following workflow. If it works then open an issue on [BuildKit](https://github.com/moby/buildkit)
+repository.
+
+```yaml
+name: containerd
+
+on:
+  push:
+
+jobs:
+  containerd:
+    runs-on: ubuntu-latest
+    steps:
+      -

+        uses: docker/setup-qemu-action@v3
+      -
+        name: Set up Docker Buildx
+        uses: docker/setup-buildx-action@v3

+        name: Set up containerd
+        uses: crazy-max/ghaction-setup-containerd@v2
+      -
+        name: Build Docker image
+        uses: docker/build-push-action@v6
+        with:
+          context: .
+          platforms: linux/amd64,linux/arm64
+          tags: docker.io/user/app:latest
+          outputs: type=oci,dest=/tmp/image.tar
+      -
+        name: Import image in containerd
+        run: |
+          sudo ctr i import --base-name docker.io/user/app --digests --all-platforms /tmp/image.tar
+      -
+        name: Push image with containerd
+        run: |
+          sudo ctr --debug i push --user "${{ secrets.DOCKER_USERNAME }}:${{ secrets.DOCKER_PASSWORD }}" docker.io/user/app:latest
+```
+
+## `repository name must be lowercase`
+
+You may encounter this issue if you're using `github.repository` as a repo slug
+in your tag:
+
+```
+#6 exporting to image
+#6 exporting layers
+#6 exporting layers 1.2s done
+#6 exporting manifest sha256:b47f7dfb97b89ccd5de553af3c8cd94c4795884cbe5693e93946b1d95a7b1d12 0.0s done
+#6 exporting config sha256:995e93fab8196893192f08a38deea6769dc4d98f86cf705eccc24ec96a3e271c 0.0s done
+#6 ERROR: invalid reference format: repository name must be lowercase
+------
+ > exporting to image:
+------
+error: failed to solve: invalid reference format: repository name must be lowercase
+```
+
+or a cache reference:
+
+```
+#10 importing cache manifest from ghcr.io/My-Org/repo:main
+#10 ERROR: invalid reference format: repository name must be lowercase
+```
+
+To fix this issue you can use our [metadata action](https://github.com/docker/metadata-action)
+to generate sanitized tags:
+
+```yaml
+- name: Docker meta
+  id: meta
+  uses: docker/metadata-action@v4
+  with:
+    images: ghcr.io/${{ github.repository }}
+    tags: latest
+
+- name: Build and push
+  uses: docker/build-push-action@v6
+  with:
+    context: .
+    push: true
+    tags: ${{ steps.meta.outputs.tags }}
+```
+
+Or a dedicated step to sanitize the slug:
+
+```yaml
+- name: Sanitize repo slug
+  uses: actions/github-script@v6
+  id: repo_slug
+  with:
+    result-encoding: string
+    script: return 'ghcr.io/${{ github.repository }}'.toLowerCase()
+
+- name: Build and push
+  uses: docker/build-push-action@v6
+  with:
+    context: .
+    push: true
+    tags: ${{ steps.repo_slug.outputs.result }}:latest
+```
