-For security reasons related to the CI, when a user no longer contributes for a long period, it will be considered inactive and removed from the authorized user's list.
-For now, it's configured for **4 months**, and it's computed based on the latest commit, not comments or opened issues.
-After that time, the CI bot will ask to remove the user name from the authorized users' list through the access request PR, which occurs a few times every week.

 ## Build Method
 
-* `build()` method should focus on build only, not installation. During the build, nothing should be written in `package` folder. Installation step should only occur in `package()` method.
-
-* The build itself should only rely on local files. Nothing should be downloaded from the internet during this step. If external files are required, they should come from `requirements` or `build_requirements` in addition to source files downloaded in `source()` or coming from the recipe itself through `export()` or `export_sources()`.
-
-* Except for CMake, a working build toolchain (compiler, linker, archiver, etc.), and a "native generator" (`make` on *nix platforms, `mingw32-make` for MinGW, `MSBuild`/`NMake` for Visual Studio), the recipe should not assume that any other build tool is installed on the user-build machine (like Meson, autotools, or pkg-config). On Windows, the recipe should not assume that a shell is available (like MSYS2). Therefore, if the build method requires additional tools, they should be added to `build_requirements()`.
-  Tools explicitly marked as available by users through conf like `tools.gnu:make_program`, `tools.gnu:pkg_config`, `tools.microsoft.bash:path`, `tools.microsoft.bash:subsystem` should be taken into account to conditionally inject a build requirement (these conf should have precedence over build requirement equivalent hardcoded in the recipe).
-
-* It is forbidden to run other conan client commands during build. In other words, if upstream build files call conan under the hood (through `cmake-conan` for example or any other logic), this logic must be removed.
-
-* Settings from profile should be honored (`build_type`, `compiler.libcxx`, `compiler.cppstd`, `compiler.runtime` etc).
-
-* Compiler paths from host profile should be honored and properly propagated to underlying build system during the build:
-
-  | compiler type | conf / env var |
-  |---------------|----------------|
-  | C compiler | `c` key of `tools.build:compiler_executables`, otherwise `CC` environment variable |
-  | C++ compiler | `cpp` key of `tools.build:compiler_executables`, otherwise `CXX` environment variable |
-  | ASM compiler | `asm` key of `tools.build:compiler_executables`, otherwise `CCAS` environment variable |
-  | CUDA compiler | `cuda` key of `tools.build:compiler_executables` |
-  | Fortran compiler | `fortran` key of `tools.build:compiler_executables`, otherwise `FC` environment variable |
-  | Objective-C compiler | `objc` key of `tools.build:compiler_executables` |
-  | Objective-C++ compiler | `objcpp` key of `tools.build:compiler_executables` |
-  | Resource files compiler | `rc` key of `tools.build:compiler_executables`, otherwise `RC` environment variable |
-  | Archiver | `AR` environment variable |
-  | Linker | `LD` environment variable |
-
-  They should be curated on the fly if underlying build system expects a specific format (no spaces in path, forward slash instead of back slash, etc).
-
-* These compiler and linker conf from host profile should be honored and propagated to underlying build system during the build:
-  * `tools.build:cflags`
-  * `tools.build:cxxflags`
-  * `tools.build:defines`
-  * `tools.build:sharedlinklags`
-  * `tools.build:exelinkflags`
-  * `tools.apple:enable_bitcode` (only if host OS is `iOS`/`watchOS`/`tvOS`)
-
-* Multithread build (if supported by underlying build system):
-  * if some steps are sensitive to race conditions, monothread should be enforced.
-  * otherwise multithreaded build should be enabled with a number of cores controlled by `tools.build:jobs` conf from host profile if it is set, otherwise to all cores of build machine.
+For the `build()` method, the general scope used to build artifacts. Please, read
+the official reference to [build()](https://docs.conan.io/2/reference/conanfile/methods/build.html) method.and the
+[Build packages: the build() method](https://docs.conan.io/2/tutorial/creating_packages/build_packages.html).
 
 ## Package Method
 
-* CMake config files must be removed. They will be generated for consumers by `CMakeDeps` generator (or legacy `cmake_find_package`/`cmake_find_package_multi` generators).
-
-* pkg-config files must be removed. They will be generated for consumers by `PkgConfigDeps` generator (or legacy `pkg_config` generator).
-
-* On *nix systems, executables and shared libraries should have empty `RPATH`/`RUNPATH`/`LC_RPATH`. Though, a relative path pointing inside package itself is allowed.
-
-* On Apple OS family:
-  * shared libs: name field of `LC_ID_DYLIB` load command must be `@rpath/<libfilename>`.
-  * shared libs & executables: name field of each `LC_LOAD_DYLIB` load command should be `@rpath/<libdependencyfilename>` (except those refering to system libs or frameworks).
-
-* Installed files must not contain absolute paths specific to build machine. Relative paths to other packages is also forbidden since relative paths of dependencies during build may not be the same for consumers. Hardcoded relative paths pointing to a location in the package itself are allowed.
-
-* Static and shared flavors of the same library must not be packaged together.
+The `package()` method is used to copy the artifacts to the `package_folder`. Please, read the official reference to
+[package()](https://docs.conan.io/2/reference/conanfile/methods/package.html) method and the

 ### Header Only
 
 If you are looking for header-only projects, you can take a look on [header-only template](../package_templates/header_only).

 ### CMake
 
 For C/C++ projects which use CMake for building, you can take a look on [cmake package template](../package_templates/cmake_package).
 
-Another common use case for CMake based projects, both header only and compiled, is _modeling components_ to match the `find_package` and export the correct targets from Conan's generators. A basic examples of this is [cpu_features](https://github.com/conan-io/conan-center-index/blob/master/recipes/cpu_features/all/conanfile.py), a moderate/intermediate example is [cpprestsdk](https://github.com/conan-io/conan-center-index/blob/master/recipes/cpprestsdk/all/conanfile.py), and a very complex example is [OpenCV](https://github.com/conan-io/conan-center-index/blob/master/recipes/opencv/4.x/conanfile.py).

 ### Autotools
 
 There is an [autotools package template](../package_templates/autotools_package/) amiable to start from.
 
-However, if you need to use autotools for building, you can take a look on [libalsa](https://github.com/conan-io/conan-center-index/blob/master/recipes/libalsa/all/conanfile.py), [kmod](https://github.com/conan-io/conan-center-index/blob/master/recipes/kmod/all/conanfile.py), [libcap](https://github.com/conan-io/conan-center-index/blob/master/recipes/libcap/all/conanfile.py).
-
-Many projects offer [**pkg-config**'s](https://www.freedesktop.org/wiki/Software/pkg-config/) `*.pc` files which need to be modeled using components. A prime example of this is [Wayland](https://github.com/conan-io/conan-center-index/blob/master/recipes/wayland/all/conanfile.py).
-
 ### No Upstream Build Scripts
 
-For cases where a project only offers source files, but not a build script, you can add CMake support, but first, contact the upstream and open a PR offering building support. If it's rejected because the author doesn't want any kind of build script, or the project is abandoned, CCI can accept your build script. Take a look at [Bzip2](https://github.com/conan-io/conan-center-index/blob/master/recipes/bzip2/all/CMakeLists.txt) and [DirectShowBaseClasses](https://github.com/conan-io/conan-center-index/blob/master/recipes/directshowbaseclasses/all/CMakeLists.txt) as examples.

+The [package_manager](https://docs.conan.io/2/reference/tools/system/package_manager.html#conan-tools-system-package-manager) can easily manage a system package manager (e.g. apt,
