 * [Shapesecurity/F5](https://www.shapesecurity.com/) Shapesecurity defends against application fraud attacks like Account Take Over, Credential Stuffing, Fake Accounts, etc. Required by FedRamp certification, we needed to find a FIM solution to help monitor and protect our Kubernetes clusters. Traditional FIM solutions were not scalable and not working for our environment, but with Falco we found the solution we needed. Falco's detection capabilities have helped us identify anomalous behaviour within our clusters. We leverage Sidekick (https://github.com/falcosecurity/charts/tree/master/falcosidekick) to send Falco alerts to a PubSub which in turn publishes those alerts to our SIEM (SumoLogic)
 
+* [Yahoo! JAPAN](https://www.yahoo.co.jp/) Yahoo! JAPAN is a leading company of internet in Japan. We build an AI Platform in our private cloud and provide it to scientists in our company. AI Platform is a multi-tenant Kubernetes environment and more flexible, faster, more efficient Machine Learning environment. Falco is used to detect unauthorized commands and malicious access and our AI Platform is monitored and alerted by Falco.
+
 * [Sysdig](https://www.sysdig.com/) Sysdig originally created Falco in 2016 to detect unexpected or suspicious activity using a rules engine on top of the data that comes from the sysdig kernel system call driver. Sysdig provides tooling to help with vulnerability management, compliance, detection, incident response and forensics in Cloud-native environments. Sysdig Secure has extended Falco to include: a rule library, the ability to update macros, lists & rules via the user interface and API, automated tuning of rules, and rule creation based on profiling known system behavior. On top of the basic Falco rules, Sysdig Secure implements the concept of a "Security policy" that can comprise several rules which are evaluated for a user-defined infrastructure scope like Kubernetes namespaces, OpenShift clusters, deployment workload, cloud regions etc.
 
-* [Thales Group](https://www.thalesgroup.com) Thales is a global technology leader with more than 81,000 employees on five continents. The Thales Group is investing in digital and “deep tech” innovations – Big Data, artificial intelligence, connectivity, cybersecurity and quantum technology – to build a future we can all trust. In the past few years, the Cloud-Native paradigms and its frameworks and tools have challenged the way applications and services are developed, delivered, and instantiated. All sorts of services are container-based workloads managed by higher level layers of orchestration such as the Kubernetes environment. Thales is committed to develop Cloud-Native services and to provide its customers with security features that ensure their applications and services are protected against cyber threats. Falco is a framework that can help Thales' products and services reach the level of trust, security and safety our clients need.
-
-* [Vinted](https://vinted.com/) Vinted uses Falco to continuously monitor container activities, identifying security threats, and ensuring compliance. The container-native approach, rule-based real-time threat detection, community support, extensibility, and compliance capabilities are the main factors why we chose it to enhance Vinted Kubernetes security. Falco Sidekick is used to send critical and warning severity alerts to our incident management solution (RTIR).
-
 * [Xenit AB](https://xenit.se/contact/) Xenit is a growth company with services within cloud and digital transformation. We provide an open-source Kubernetes framework that we leverage to help our customers get their applications to production as quickly and as securely as possible. We use Falco's detection capabilities to identify anomalous behaviour within our clusters in both Azure and AWS.

 ## Projects that use Falco libs
 
 * [R6/Phoenix](https://r6security.com/) is an attack surface protection company that uses moving target defense to provide fully automated, proactive and devops friendly security to its customers. There are a set of policies you can add to enable the moving target defense capabilities. Some of them are triggered by a combination of Falco's findings. You can kill, restart and rename pods according to the ever changing policies.

-## v0.36.0
-
-Released on 2023-09-25
-
-### Breaking Changes
-
-- The default rules file that is shipped in the Falco image and/or can be downloaded via falcoctl as `falco-rules` is now a _stable_ rule file. This file **contains a much smaller number of rules** that are less noisy and have been vetted by the community. This serves as a much requested "starter" Falco rule set that covers many common use case. The rest of that file has been expanded and split into `falco-incubating-rules` and `falco-sandbox-rules`. For more information, see the [rules repository](https://github.com/falcosecurity/rules)
-- The main `falcosecurity/falco` container image and its `falco-driver-loader` counterpart have been upgraded. Now they are able to compile the kernel module or classic eBPF probe for relatively newer version of the kernel (5.x and above) while we no longer ship toolchains to compile the kernel module for older versions in the default images. Downloading of prebuilt drivers and the modern eBPF will work exactly like before. The older image, meant for compatibility with older kernels (4.x and below), is currently retained as `falcosecurity/falco-driver-loader-legacy`.
-- The Falco HTTP output no longer logs to stdout by default for performance reasons. You can set stdout logging preferences and restore the previous behavior with the configuration option `http_output.echo` in `falco.yaml`.
-- The `--list-syscall-events` command line option has been replaced by `--list-events` which prints all supported system events (syscall, tracepoints, metaevents, internal plugin events) in addition to extra information about flags.
-- The semantics of `proc.exepath` have changed. Now that field contains the executable path on disk even if the binary was launched from a symbolic link.
-- The `-d` daemonize option has been removed.
-- The `-p` option is now changed:
-    - when only `-pc` is set Falco will print `container_id=%container.id container_image=%container.image.repository container_image_tag=%container.image.tag container_name=%container.name`
-    - when `-pk` is set it will print as above, but with `k8s_ns=%k8s.ns.name k8s_pod_name=%k8s.pod.name` appended

-      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

-      (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.

-## Why is Falco in C++ rather than Go or {language}?
-
-1. The first lines of code at the base of Falco were written some time ago, where Go didn't yet have the same level of maturity and adoption as today.
-2. The Falco execution model is sequential and mono-thread due to the statefulness requirements of the tool, and so most of the concurrency-related selling points of the Go runtime would not be leveraged at all.
-3. The Falco code deals with very low-level programming in many places (e.g. some headers are shared with the eBPF probe and the Kernel module), and we all know that interfacing Go with C is possible but brings tons of complexity and tradeoffs to the table.
-4. As a security tool meant to consume a crazy high throughput of events per second, Falco needs to squeeze performance in all hot paths at runtime and requires deep control on memory allocation, which the Go runtime can't provide (there's also garbage collection involved).
-5. Although Go didn't suit the engineering requirements of the core of Falco, we still thought that it could be a good candidate for writing Falco extensions through the plugin system. This is the main reason we gave special attention and high priority to the development of the plugin-sdk-go.
-6. Go is not a requirement for having statically-linked binaries. In fact, we provide fully-static Falco builds since few years. The only issue with those is that the plugin system can't be supported with the current dynamic library model we currently have.
-7. The plugin system has been envisioned to support multiple languages, so on our end maintaining a C-compatible codebase is the best strategy to ensure maximum cross-language compatibility.
-8. In general, plugins have GLIBC requirements/dependencies because they have low-level C bindings required for dynamic loading. A potential solution for the future could be to also support plugin to be statically-linked at compilation time and so released as bundled in the Falco binary. Although no work started yet in this direction, this would solve most issues you reported and would provide a totally-static binary too. Of course, this would not be compatible with dynamic loading anymore, but it may be a viable solution for our static-build flavor of Falco.
-9. Memory safety is definitely a concern and we try our best to keep an high level of quality even though C++ is quite error prone. For instance, we try to use smart pointers whenever possible, we build the libraries with an address sanitizer in our CI, we run Falco through Valgrind before each release, and have ways to stress-test it to detect performance regressions or weird memory usage (e.g. https://github.com/falcosecurity/event-generator). On top of that, we also have third parties auditing the codebase by time to time. None of this make a perfect safety standpoint of course, but we try to maximize our odds. Go would definitely make our life easier from this perspective, however the tradeoffs never made it worth it so far due to the points above.
-10. The C++ codebase of falcosecurity/libs, which is at the core of Falco, is quite large and complex. Porting all that code to another language would be a major effort requiring lots of development resource and with an high chance of failure and regression. As such, our approach so far has been to choose refactors and code polishing instead, up until we'll reach an optimal level of stability, quality, and modularity, on that portion of code. This would allow further developments to be smoother and more feasibile in the future.

 ### Falco repo (this repo)
 - Falco version is a git tag (`x.y.z`), see [Procedures](#procedures) section. Note that the Falco version is a sem-ver-like schema, but not fully compatible with sem-ver.
-- [FALCO_ENGINE_VERSION](https://github.com/falcosecurity/falco/blob/master/userspace/engine/falco_engine_version.h) is not sem-ver and must be bumped either when a backward incompatible change has been introduced to the rules files syntax and loading logic, and/or when `FALCO_ENGINE_CHECKSUM` has changed. The checksum is computed by considering the available rules fields (see currently supported [Falco fields](https://falco.org/docs/reference/rules/supported-fields/)), the event types (see currently supported [Falco events](https://falco.org/docs/reference/rules/supported-events/)), and the supported driver schema version. A checksum indicates that something was not available in previous engine versions. See the [rules release guidelines](https://github.com/falcosecurity/rules/blob/main/RELEASE.md#versioning-a-ruleset) to understand how this affects the versioning of Falco rules. Breaking changes introduced in the Falco engine are not necessarily tied to the drivers or libs versions. The version number must be incremented every time and only when a single change or an atomic group of changes - which meet the criteria described above - is included in the `master` branch. Thus, a version bump can occur multiple times during the development and testing phases of a given release cycle. A given version bump must not group multiple changes that occurred sporadically during the release cycle.
+- [FALCO_ENGINE_VERSION](https://github.com/falcosecurity/falco/blob/master/userspace/engine/falco_engine_version.h) is not sem-ver and must be bumped either when a backward incompatible change has been introduced to the rules files syntax and/or `FALCO_FIELDS_CHECKSUM` computed via `falco --list -N | sha256sum` has changed. The primary idea is that when new filter / display fields (see currently supported [Falco fields](https://falco.org/docs/rules/supported-fields/)) are introduced, a version change indicates that these fields were not available in previous engine versions. See the [rules release guidelines](https://github.com/falcosecurity/rules/blob/main/RELEASE.md#versioning-a-ruleset) to understand how this affects the versioning of Falco rules. Breaking changes introduced in the Falco engine are not necessarily tied to the drivers or libs versions. Lastly, `FALCO_ENGINE_VERSION` is typically incremented once during a Falco release cycle, while `FALCO_FIELDS_CHECKSUM` is bumped whenever necessary during the development and testing phases of the release cycle.
 - During development and release preparation, libs and driver reference commits are often bumped in Falco's cmake setup ([falcosecurity-libs cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/falcosecurity-libs.cmake#L30) and [driver cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/driver.cmake#L29)) in order to merge new Falco features. In practice, they are mostly bumped at the same time referencing the same `libs` commit. However, for the official Falco build `FALCOSECURITY_LIBS_VERSION` flag that references the stable libs version is used (read below).
 - Similarly, Falco plugins versions are bumped in Falco's cmake setup ([plugins cmake](https://github.com/falcosecurity/falco/blob/master/cmake/modules/plugins.cmake)) and those versions are the ones used for the Falco release.
 - At release time Plugin, Libs and Driver versions are compatible with Falco.

 > Cloud Native Runtime Security
 
+### What is Falco?
+
+Falco is a runtime security project originally created by Sysdig, Inc.
+Falco was contributed to the CNCF in October 2018.
+The CNCF now owns The Falco Project.
+
+### What is Runtime Security?
+
+Runtime security refers to an approach to preventing unwanted activity on a computer system. 
+With runtime security, an operator deploys **both** prevention tooling (access control, policy enforcement, etc) along side detection tooling (systems observability, anomaly detection, etc).
+Runtime security is the practice of using detection tooling to detect unwanted behavior, such that it can then be prevented using prevention techniques.
+Runtime security is a holistic approach to defense, and useful in scenarios where prevention tooling either was unaware of an exploit or attack vector, or when defective applications are ran in even the most secure environment.
+
+### What does Falco do?
+
+Falco consumes signals from the Linux kernel, and container management tools such as Docker and Kubernetes.
+Falco parses the signals and asserts them against security rules.
+If a rule has been violated, Falco triggers an alert. 
+
+### How does Falco work?
+
+Falco traces kernel events and reports information about the system calls being executed at runtime.
+Falco leverages the extended berkeley packet filter (eBPF) which is a kernel feature implemented for dynamic crash-resilient and secure code execution in the kernel. 
+Falco enriches these kernel events with information about containers running on the system.
+Falco also can consume signals from other input streams such as the containerd socket, the Kubernetes API server and the Kubernetes audit log.
+At runtime, Falco will reason about these events and assert them against configured security rules.
+Based on the severity of a violation an alert is triggered.
+These alerts are configurable and extensible, for instance sending a notification or [plumbing through to other projects like Prometheus](https://github.com/falcosecurity/falco-exporter). 
+
+### Benefits of using Falco
+
+ - **Strengthen Security** Create security rules driven by a context-rich and flexible engine to define unexpected application behavior.
+ - **Reduce Risk** Immediately respond to policy violation alerts by plugging Falco into your current security response workflows and processes.
+ - **Leverage up-to-date Rules** Alert using community-sourced detections of malicious activity and CVE exploits.
+    
+### Falco and securing Kubernetes
+
+Securing Kubernetes requires putting controls in place to detect unexpected behavior that could be malicious or harmful to a cluster or application(s). 
+
+Examples of malicious behavior include: 
+
+ - Exploits of unpatched and new vulnerabilities in applications or Kubernetes itself. 
+ - Insecure configurations in applications or Kubernetes itself. 
+ - Leaked or weak credentials or secret material.
+ - Insider threats from adjacent applications running at the same layer. 
+
+Falco is capable of [consuming the Kubernetes audit logs](https://kubernetes.io/docs/tasks/debug-application-cluster/falco/#use-falco-to-collect-audit-events).
+By adding Kubernetes application context, and Kubernetes audit logs teams can understand who did what.

+### Encouraged Phrasing
+
+Below are phrases that the project has reviewed, and found to be effective ways of messaging Falco's value add.
+Even when processes are in place for vulnerability scanning and implementing pod security and network policies, not every risk will be addressed. You still need mechanisms to confirm these security barriers are effective, help configure them, and provide with a last line of defense when they fail.
+
+##### Falco as a factory
+
+This term refers to the concept that Falco is a stateless processing engine. A large amount of data comes into the engine, but meticulously crafted security alerts come out.
+
+##### The engine that powers...
+
+Falco ultimately is a security engine. It reasons about signals coming from a system at runtime, and can alert if an anomaly is detected.
+
+##### Anomaly detection
+
+This refers to an event that occurs with something unusual, concerning, or odd occurs.
+We can associate anomalies with unwanted behavior, and alert in their presence.
+
+##### Detection tooling
+
+Falco does not prevent unwanted behavior.
+Falco however alerts when unusual behavior occurs.
+This is commonly referred to as **detection** or **forensics**.

+    - a bind-mount on the source directory (ie., the directory containing the Falco source as sibling)
+
+    Optionally, you can also bind-mount the build directory.
+    So, you can execute it from the Falco root directory as follows.
+
+    * docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder cmake
+    * docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder [<cmake-target-x>, ..., <cmake-target-y>]
+
+    Eg.,
+    * docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder tests
+    * docker run -v $PWD/..:/source -v $PWD/build:/build falcosecurity/falco-builder install
+
+How to build.
+
+    * cd docker/builder && DOCKER_BUILDKIT=1 docker build -t falcosecurity/falco-builder .
+
+    In case you want to customise the builder at build time the following build arguments are provided:
+    - BUILD_TYPE                whether you want a "release" or "debug" build (defaults to "release").
+    - BUILD_DRIVER              whether to build the driver or not (defaults to "OFF")
+    - BUILD_BPF                 whether to build the BPF driver or not (defaults to "OFF")
+    - BUILD_WARNINGS_AS_ERRORS  whether to intend warnings as errors or not (defaults to "ON")
+    - MAKE_JOBS                 the number of jobs to use during make (defaults to "4")
+    - FALCO_VERSION             the version to label the build (built from git index in case it is missing)
+
+    It is possible to change these at runtime (in the container) since environment variables with the same names are provided, too.
+
+Environment.
+
+    * ${gccversion}
+    * cplusplus ${cppversion}
+    * ${cmakeversion}
+    * ${clangversion}

+# Falco regression tests
+
+This folder contains the Regression tests suite for Falco.
+
+You can find instructions on how to run this test suite on the Falco website [here](https://falco.org/docs/getting-started/source/#run-regression-tests).
+
+## Test suites
+
+- [falco_tests](./falco_tests.yaml)
+- [falco_traces](./falco_traces.yaml.in)
+- [falco_tests_package](./falco_tests_package.yaml)
+- [falco_k8s_audit_tests](./falco_k8s_audit_tests.yaml)
+
+## Running locally
+
+This step assumes you already built Falco.
+
+Note that the tests are intended to be run against a [release build](https://falco.org/docs/getting-started/source/#specify-the-build-type) of Falco, at the moment.
+
+Also, it assumes you prepared [falco_traces](#falco_traces) (see the section below).
+
+**Requirements**
+
+- Python 3.x
+- [Virtualenv](https://virtualenv.pypa.io/en/latest/)
+- [grpcurl](https://github.com/fullstorydev/grpcurl)
+
+**Setup and execution**
+
+Using `virtualenv` the steps to locally run a specific test suite are the following ones (**from this directory**):
+
+```console
+virtualenv venv
+source venv/bin/activate
+pip install -r requirements.txt
+BUILD_DIR="../build" avocado run --mux-yaml falco_tests.yaml --job-results-dir /tmp/job-results -- falco_test.py
+deactivate
+```
+
+The name of the specific test suite to run is `falco_tests.yaml` in this case. Change it to run others test suites.
+
+In case you want to only execute a specific test case, use the `--mux-filter-only` parameter as follows:
+
+```console
+BUILD_DIR="../build" avocado run --mux-yaml falco_tests.yaml --job-results-dir /tmp/job-results --mux-filter-only /run/trace_files/program_output -- falco_test.py
+```
+
+To obtain the path of all the available variants for a given test suite, execute:
+
+```console
+avocado variants --mux-yaml falco_tests.yaml
+```
+
+### falco_traces
+
+The `falco_traces.yaml` test suite gets generated through the `falco_traces.yaml.in` file and some fixtures (`scap` files) downloaded from the web at execution time.
+
+1. Ensure you have `unzip` and `xargs` utilities
+2. Prepare the test suite with the following command:
+
+    ```console
+    bash run_regression_tests.sh -p -v
+    ```
+
+### falco_tests_package
+
+The `falco_tests_package.yaml` test suite requires some additional setup steps to be successfully run on your local machine.
+
+In particular, it requires some runners (ie., docker images) to be already built and present into your local machine.
+
+1. Ensure you have `docker` up and running
+2. Ensure you build Falco (with bundled deps)
+
+    The recommended way of doing it by running the `falcosecurity/falco-builder` docker image from the project root:
+
+    ```console
+    docker run -v $PWD/..:/source -v $PWD/mybuild:/build falcosecurity/falco-builder cmake
+    docker run -v $PWD/..:/source -v $PWD/mybuild:/build falcosecurity/falco-builder falco
+    ```
+
+3. Ensure you build the Falco packages from the Falco above:
+
+    ```console
+    docker run -v $PWD/..:/source -v $PWD/mybuild:/build falcosecurity/falco-builder package
+    ```
+
+4. Ensure you build the runners:
+
+    ```console
+    FALCO_VERSION=$(./mybuild/release/userspace/falco/falco --version  | head -n 1 | cut -d' ' -f3 | tr -d '\r')
+    mkdir -p /tmp/runners-rootfs
+    cp -R ./test/rules /tmp/runners-rootfs
+    cp -R ./test/trace_files /tmp/runners-rootfs
+    cp ./mybuild/release/falco-${FALCO_VERSION}-x86_64.{deb,rpm,tar.gz} /tmp/runners-rootfs
+    docker build -f docker/tester/root/runners/deb.Dockerfile --build-arg FALCO_VERSION=${FALCO_VERSION} -t falcosecurity/falco:test-deb /tmp/runners-rootfs
+    docker build -f docker/tester/root/runners/rpm.Dockerfile --build-arg FALCO_VERSION=${FALCO_VERSION} -t falcosecurity/falco:test-rpm /tmp/runners-rootfs
+    docker build -f docker/tester/root/runners/tar.gz.Dockerfile --build-arg FALCO_VERSION=${FALCO_VERSION} -t falcosecurity/falco:test-tar.gz /tmp/runners-rootfs
+    ```
+
+5. Run the `falco_tests_package.yaml` test suite from the `test` directory
+
+    ```console
+    cd test
+    BUILD_DIR="../mybuild" avocado run --mux-yaml falco_tests_package.yaml --job-results-dir /tmp/job-results -- falco_test.py
+    ```
+
+### Execute all the test suites
+
+In case you want to run all the test suites at once, you can directly use the `run_regression_tests.sh` runner script.
+
+```console
+cd test
+./run_regression_tests.sh -v -d ../build
+```
+
+Just make sure you followed all the previous setup steps.
