 ### Run the unit- and integration-tests
 
-Running tests:

-```bash
-make test

-
-This runs all unit and integration tests, in a containerized environment.
-Locally, every package can be tested separately with standard Go tools, but
-integration tests are skipped if local user doesn't have enough permissions or
-worker binaries are not installed.

-```bash
-# run unit tests only
-make test-unit

-# run integration tests only
-make test-integration

-# test a specific package
-TESTPKGS=./bake make test

-# run all integration tests with a specific worker
-TESTFLAGS="--run=//worker=remote -v" make test-integration
-
-# run a specific integration test
-TESTFLAGS="--run /TestBuild/worker=remote/ -v" make test-integration
-
-# run a selection of integration tests using a regexp
-TESTFLAGS="--run /TestBuild.*/worker=remote/ -v" make test-integration

-### Generate profiling data
-
-You can configure Buildx to generate [`pprof`](https://github.com/google/pprof)
-memory and CPU profiles to analyze and optimize your builds. These profiles are
-useful for identifying performance bottlenecks, detecting memory
-inefficiencies, and ensuring the program (Buildx) runs efficiently.
-
-The following environment variables control whether Buildx generates profiling
-data for builds:
-
-```console
-$ export BUILDX_CPU_PROFILE=buildx_cpu.prof
-$ export BUILDX_MEM_PROFILE=buildx_mem.prof
-```
-
-When set, Buildx emits profiling samples for the builds to the location
-specified by the environment variable.
-
-To analyze and visualize profiling samples, you need `pprof` from the Go
-toolchain, and (optionally) GraphViz for visualization in a graphical format.
-
-To inspect profiling data with `pprof`:
-
-1. Build a local binary of Buildx from source.
-
-   ```console
-   $ docker buildx bake
-   ```
-
-   The binary gets exported to `./bin/build/buildx`.
-
-2. Run a build and with the environment variables set to generate profiling data.
-
-   ```console
-   $ export BUILDX_CPU_PROFILE=buildx_cpu.prof
-   $ export BUILDX_MEM_PROFILE=buildx_mem.prof
-   $ ./bin/build/buildx bake
-   ```
-
-   This creates `buildx_cpu.prof` and `buildx_mem.prof` for the build.
-
-3. Start `pprof` and specify the filename of the profile that you want to
-   analyze.
-
-   ```console
-   $ go tool pprof buildx_cpu.prof
-   ```
-
-   This opens the `pprof` interactive console. From here, you can inspect the
-   profiling sample using various commands. For example, use `top 10` command
-   to view the top 10 most time-consuming entries.
-
-   ```plaintext

-## Project scope
-
-**Docker Buildx** is a Docker CLI plugin designed to extend build capabilities using BuildKit. It provides advanced features for building container images, supporting multiple builder instances, multi-node builds, and high-level build constructs. Buildx enhances the Docker build process, making it more efficient and flexible, and is compatible with both Docker and Kubernetes environments. Key features include:
-
-- **Familiar user experience:** Buildx offers a user experience similar to legacy docker build, ensuring a smooth transition from legacy commands
-- **Full BuildKit capabilities:** Leverage the full feature set of [`moby/buildkit`](https://github.com/moby/buildkit) when using the container driver
-- **Multiple builder instances:** Supports the use of multiple builder instances, allowing concurrent builds and effective management and monitoring of these builders.
-- **Multi-node builds:** Use multiple nodes to build cross-platform images
-- **Compose integration:** Build complex, multi-services files as defined in compose
-- **High-level build constructs via `bake`:** Introduces high-level build constructs for more complex build workflows
-- **In-container driver support:** Support in-container drivers for both Docker and Kubernetes environments to support isolation/security.

-## Types of releases
-
-This project has feature releases, patch releases, and security releases.
-
-### Feature releases
-
-Feature releases are made from the development branch, followed by cutting a release branch for future patch releases, which may also occur during the code freeze period.
-
-#### Release Candidates
-
-Users can expect 2-3 release candidate (RC) test releases prior to a feature release. The first RC is typically released about one to two weeks before the final release.
-
-#### Support Policy
-
-Once a new feature release is cut, support for the previous feature release is discontinued. An exception may be made for urgent security releases that occur shortly after a new feature release. Buildx does not offer LTS (Long-Term Support) releases.
-
-#### Contributing to Releases
-
-Anyone can request that an issue or PR be included in the next feature or patch release milestone, provided it meets the necessary requirements.
-
-### Patch releases
-
-Patch releases should only include the most critical patches. Stability is vital, so everyone should always use the latest patch release.
-
-If a fix is needed but does not qualify for a patch release because of its code size or other criteria that make it too unpredictable, we will prioritize cutting a new feature release sooner rather than making an exception for backporting.
-
-Following PRs are included in patch releases
-
-- `priority/P0` fixes
-- `priority/P1` fixes, assuming maintainers don’t object because of the patch size
-- `priority/P2` fixes, only if (both required)
-    - proposed by maintainer
-    - the patch is trivial and self-contained
-- Documentation-only patches
-- Vendored dependency updates, only if:
-    - Fixing (qualifying) bug or security issue in Buildx
-    - The patch is small, else a forked version of the dependency with only the patches required
-
-New features do not qualify for patch release.
-
-## Milestones
-
-Milestones are used to help identify what releases a contribution will be in. 
-
-- The `v0.next` milestone collects unblocked items planned for the next 2-3 feature releases but not yet assigned to a specific version milestone.
-- The `v0.backlog` milestone gathers all triaged items considered for the long-term (beyond the next 3 feature releases) or currently unfit for a future release due to certain conditions. These items may be blocked and need to be unblocked before progressing.
-
-## Triage process
-
-Triage provides an important way to contribute to an open-source project. When submitted without an issue this process applies to Pull Requests as well. Triage helps ensure work items are resolved quickly by:
-
-- Ensuring the issue's intent and purpose are described precisely. This is necessary because it can be difficult for an issue to explain how an end user experiences a problem and what actions they took to arrive at the problem.
-- Giving a contributor the information they need before they commit to resolving an issue.
-- Lowering the issue count by preventing duplicate issues.
-- Streamlining the development process by preventing duplicate discussions.
-
-If you don't have time to code, consider helping with triage. The community will thank you for saving them time by spending some of yours. The same basic process should be applied upon receipt of a new issue.
-
-1. Verify essential information
-2. Classify the issue
-3. Prioritizing the issue
-
-### Verify essential information
-
-Before advancing the triage process, ensure the issue contains all necessary information to be properly understood and assessed. The required information may vary by issue type, but typically includes the system environment, version numbers, reproduction steps, expected outcomes, and actual results.
-
-- **Exercising Judgment**: Use your best judgment to assess the issue description’s completeness.
-- **Communicating Needs**: If the information provided is insufficient, kindly request additional details from the author. Explain that this information is crucial for clarity and resolution of the issue, and apply the `needs/more-information` label to indicate a response from the author is required.
-
-### Classify the issue
-
-An issue will typically have multiple labels. These are used to help communicate key information about context, requirements, and status. At a minimum, a properly classified issue should have:
-
-- (Required) One or more [`area/*`](#area) labels
-- (Required) One [`kind/*`](#kind) label  to indicate the type of issue
-- (Required if `kind/bug`) A [`priority/*`](#priority) label
-
-When assigning a decision the following labels should be present:
-
-- (Required) One [`status/*`](#status) label  to indicate lifecycle status
-
-Additional labels can provide more clarity:
-
-- Zero or more [`needs/*`](#needs) labels to indicate missing items
-- Zero or more [`impact/*`](#impact) labels
-- One [`exp/*`](#exp) label
-
-## Prioritization guidelines for `kind/bug`
-
-When an issue or pull request of `kind/bug` is correctly categorized and attached to a milestone, the labels indicate the urgency with which it should be completed. 
-
-**priority/P0**
-
-Fixing this item is the highest priority. A patch release will follow as soon as a patch is available and verified. This level is used exclusively for bugs.
-
-Examples:
-
-- Regression in a critical code path
-- Panic in a critical code path
-- Corruption in critical code path or rest of the system
-- Leaked zero-day critical security
-
-**priority/P1**
-
-Items with this label should be fixed with high priority and almost always included in a patch release. Unless waiting for another issue, patch releases should happen within a week. This level is not used for features or enhancements.
-
-Examples:
-
-- Any regression, panic
-- Measurable performance regression
-- A major bug in a new feature in the latest release
-- Incompatibility with upgraded external dependency
-
-**priority/P2**
-
-This is the default priority and is implied in the absence of a `priority/` label. Bugs with this priority should be included in the next feature release but may land in a patch release if they are ready and unlikely to impact other functionality adversely. Non-bug issues with this priority should also be included in the next feature release if they are available and ready.
-
-Examples:
-
-- Confirmed bugs
-- Bugs in non-default configurations
-- Most enhancements
-

-### Examples
-
-#### Submitting a bug
-
-To help illustrate the issue life cycle let’s walk through submitting an issue as a potential bug in CI that enters a feedback loop and is eventually accepted as P2 priority and placed on the backlog.
-
-```mermaid

-  
-  new --> triage
-  triage --> decision
-```
-
-## Pull request review process
-
-A thorough and timely review process for pull requests (PRs) is crucial for maintaining the integrity and quality of the project while fostering a collaborative environment.
-
-- **Labeling**: Most labels should be inherited from a linked issue. If no issue is linked an extended review process may be required.
-- **Continuous Integration**: With few exceptions, it is crucial that all Continuous Integration (CI) workflows pass successfully.
-- **Draft Status**: Incomplete or long-running PRs should be placed in "Draft" status. They may revert to "Draft" status upon initial review if significant rework is required.
-
-```mermaid
-flowchart LR
-  triage([Triage])
-  draft[Draft PR]
-  review[PR Review]
-  closed{{Close PR}}
-  merge{{Merge PR}}
-
-  subgraph feedback1[Feedback Loop]
-    draft
-  end
-  subgraph feedback2[Feedback Loop]
-     review
-  end
-
-  triage --> draft
-  draft --> review
-  review --> closed
-  review --> draft
-  review --> merge
-```
-
-## Handling stalled issues and pull requests
-
-Unfortunately, some issues or pull requests can remain inactive for extended periods. To mitigate this, automation is employed to prompt both the author and maintainers, ensuring that all contributions receive appropriate attention.
-
-**For Authors:**
-
-- **Closure of Inactive Items**: If your issue or PR becomes irrelevant or is no longer needed, please close it to help keep the project clean.
-- **Prompt Responses**: If additional information is requested, please respond promptly to facilitate progress.
-
-**For Maintainers:**
-
-- **Timely Responses**: Endeavor to address issues and PRs within a reasonable timeframe to keep the community actively engaged.
-- **Engagement with Stale Issues**: If an issue becomes stale due to maintainer inaction, re-engage with the author to reassess and revitalize the discussion.
-
-**Stale and Rotten Policy:**
-
-- An issue or PR will be labeled as **`stale`** after 14 calendar days of inactivity. If it remains inactive for another 30 days, it will be labeled as **`rotten`** and closed.
-- Authors whose issues or PRs have been closed are welcome to re-open them or create new ones and link to the original.
-
-**Skipping Stale Processing:**
-
-- To prevent an issue or PR from being marked as stale, label it as **`frozen`**.
-
-**Exceptions to Stale Processing:**
-
-- Issues or PRs marked as **`frozen`**.
-- Issues or PRs assigned to a milestone.
-
-## Moving to a discussion
-
-Sometimes, an issue or pull request may not be the appropriate medium for what is essentially a discussion. In such cases, the issue or PR will either be converted to a discussion or a new discussion will be created. The original item will then be labeled appropriately (**`kind/discussion`** or **`kind/question`**) and closed.
-
-If you believe this conversion was made in error, please express your concerns in the new discussion thread. If necessary, a reversal to the original issue or PR format can be facilitated.
-
-## Workflow automation
-
-To help expedite common operations, avoid errors and reduce toil some workflow automation is used by the project. This can include:
-
-- Stale issue or pull request processing
-- Auto-labeling actions
-- Auto-response actions
-- Label carry over from issue to pull request
-
-### Exempting an issue/PR from stale bot processing
-
-The stale item handling is configured in the [repository](link-to-config-file). To exempt an issue or PR from stale processing you can:
-
-- Add the item to a milestone
-- Add the `frozen` label to the item
-
-## Updating dependencies
-
-- **Runtime Dependencies**: Use the latest stable release available when the first Release Candidate (RC) of a new feature release is cut. For patch releases, update to the latest corresponding patch release of the dependency.
-- **Other Dependencies**: Always permitted to update to the latest patch release in the development branch. Updates to a new feature release require justification, unless the dependency is outdated. Prefer tagged versions of dependencies unless a specific untagged commit is needed. Go modules should specify the lowest compatible version; there is no requirement to update all dependencies to their latest versions before cutting a new Buildx feature release.
-- **Patch Releases**: Vendored dependency updates are considered for patch releases, except in the rare cases specified previously.
-- **Security Considerations**: A security scanner report indicating a non-exploitable issue via Buildx does not justify backports.

+Buildx is supposed to be flexible and can be run in different configurations
+that are exposed through a driver concept. Currently, we support a

+[`docker-container` driver](docs/reference/buildx_create.md#docker-container-driver)
+that automatically launches BuildKit inside a Docker container and a
+[`kubernetes` driver](docs/reference/buildx_create.md#kubernetes-driver) to
+spin up pods with defined BuildKit container image to build your images. We
+plan to add more drivers in the future.
 
-We currently support the following drivers:
-- The `docker` driver ([guide](https://docs.docker.com/build/drivers/docker/), [reference](https://docs.docker.com/engine/reference/commandline/buildx_create/#driver))
-- The `docker-container` driver ([guide](https://docs.docker.com/build/drivers/docker-container/), [reference](https://docs.docker.com/engine/reference/commandline/buildx_create/#driver))

+The user experience of using buildx is very similar across drivers, but there
+are some features that are not currently supported by the `docker` driver,

+are automatically added to the `docker images` view by default, whereas when
+using other drivers the method for outputting an image needs to be selected

 ## High-level build options
 
-See [High-level builds with Bake](https://docs.docker.com/build/bake/) for more details.
+Buildx also aims to provide support for high-level build concepts that go beyond
+invoking a single build command. We want to support building all the images in
+your application together and let the users define project specific reusable
+build flows that can then be easily invoked by anyone.
+
+BuildKit efficiently handles multiple concurrent build requests and
+de-duplicating work. The build commands can be combined with general-purpose
+command runners (for example, `make`). However, these tools generally invoke
+builds in sequence  and therefore cannot leverage the full potential of BuildKit
+parallelization, or combine BuildKit’s output for the user. For this use case,
+we have added a command called [`docker buildx bake`](docs/reference/buildx_bake.md).
+
+The `bake` command supports building images from compose files, similar to
+[`docker-compose build`](https://docs.docker.com/compose/reference/build/),
+but allowing all the services to be built concurrently as part of a single
+request.
+
+There is also support for custom build rules from HCL/JSON files allowing
+better code reuse and different target groups. The design of bake is in very
+early stages and we are looking for feedback from users.
