+Falco's [Build Falco from source](https://falco.org/docs/install-operate/source/) is the go-to resource to understand how to build Falco from source. In addition, the [falcosecurity/libs](https://github.com/falcosecurity/libs) repository offers additional valuable information about tests and debugging of Falco's underlying libraries and kernel drivers.
+
+Here's an example of a `cmake` command that will enable everything you need for all unit tests of this repository:
+
+```bash
+cmake \
+-DUSE_BUNDLED_DEPS=ON \
+-DBUILD_LIBSCAP_GVISOR=ON \
+-DBUILD_BPF=ON \
+-DBUILD_DRIVER=ON \
+-DBUILD_FALCO_MODERN_BPF=ON \
+-DCREATE_TEST_TARGETS=ON \
+-DBUILD_FALCO_UNIT_TESTS=ON ..;
+```
+
+Build and run the unit test suite:
+
+```bash
+nproc=$(grep processor /proc/cpuinfo | tail -n 1 | awk '{print $3}');
+make -j$(($nproc-1)) falco_unit_tests;
+# Run the tests
+sudo ./unit_tests/falco_unit_tests;
+```
+
+Optionally, build the driver of your choice and test run the Falco binary to perform manual tests.
+
+Lastly, The Falco Project has moved its Falco regression tests to [falcosecurity/testing](https://github.com/falcosecurity/testing).

 ## Why is Falco in C++ rather than Go or {language}?
 
+<details>

 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.

 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.
