+# FAQ
+
+## What is this project about?
+`dcr` is a tool for managing C/C++ projects and their dependencies.
+It is inspired by Cargo, but it is not a direct equivalent of Makefile, CMake, or other classic build systems.
+
+The goal is to provide a simpler and easier-to-configure development workflow.
+
+## How is the project developed?
+The project is written in Rust and is primarily developed by one maintainer, Dexoron.
+
+AI tools are used during development, but they do not write the project end-to-end. Their role is limited to supporting specific tasks (for example, suggestions, wording checks, and translations).
+
+## Which tools are used for development?
+Main development stack:
+- `RustRover` 2025 - development IDE.
+- `Codex` (`GPT-5.3-Codex (medium)`) - primary AI tool, integrated via JetBrains AI Chat.
+- `Rust` - main project language.
+- `Cargo` - tool for building, testing, and dependency management in Rust projects.
+
+## Is the project open source?
+Yes, the project is open source.
+You can propose ideas, report issues, and contribute code changes.
+
+The project is distributed under the MIT license (see `LICENSE`).
+
+## How can I contribute?
+Thank you for contributing.
+You can:
+- help with code;
+- help with translations;
+- help with documentation;
+- suggest an idea or report a bug.
+
+### If you want to submit changes (code, translation, documentation)
+1. Fork the required repository: `dexoron/dcr` (main project) or `dexoron/dcr-site` (project website).
+2. Make your changes following the rules in `CONTRIBUTING.md`.
+3. Push changes to your fork.
+4. Open a Pull Request.
+5. Wait for review.
+
+### If you want to report a problem or suggest an idea
+1. Open the relevant repository: `dexoron/dcr` or `dexoron/dcr-site`.
+2. Go to the `Issues` tab.
+3. Create an Issue and specify its type (bug, suggestion, question/help).
+4. Describe the problem or idea clearly and concisely.
+5. Wait for feedback.
+
+## How do I install `dcr`?
+Available installation methods may vary by project version.
+Recommended path:
+- check instructions in `README.md`;
+- if there is no prebuilt package for your platform, build from source using `cargo build --release`.
+
+## How can I get started quickly?
+Minimal workflow:
+1. Install `dcr`.
+2. Create a project (or open an existing C/C++ project).
+3. Initialize `dcr` configuration.
+4. Add project dependencies.
+5. Build using `dcr`.
+
+For detailed commands and examples, see `README.md` and the project documentation.
+
+## What is the project status?
+`dcr` is under active development.
+This means some interfaces and behaviors may change between versions.
+
+Before upgrading, check the changelog and release notes.
+
+## Which systems does `dcr` support?
+`dcr` targets modern C/C++ development environments.
+Actual compatibility depends on the `dcr` version, operating system, and toolchain.
+
+Before starting, check documentation for:
+- supported operating systems;
+- supported compilers and linkers;
+- version-specific limitations.
+
+## How is `dcr` different from Make/CMake?
+`dcr` does not aim to be a direct replacement for Make/CMake.
+Its main focus is simplifying project and dependency management with a Cargo-like experience.
+
+If you need low-level, full control over build steps, classic tools may be a better fit.
+If you want a simpler and more uniform configuration model, `dcr` may be more convenient.
+
+## Where can I find documentation and examples?
+Primary sources:
+- `README.md` in the repository;
+- project documentation (see the project website);
+- `Issues` for known problems and discussions.
+
+## How do I report a bug properly?
+To make a bug report easy to reproduce, include:
+1. `dcr` version.
+2. OS and compiler/toolchain version.
+3. Steps to reproduce.
+4. Expected behavior.
+5. Actual behavior and error output.
+6. Minimal project example (if possible).
+
+Submit bugs and issues through `Issues` in the relevant repository.

 # DCR (Dexoron Cargo Realization)
 
-DCR — это утилита для управления проектами на C. Она задает единый формат проекта, дает команды для создания, сборки и запуска, и использует один конфигурационный файл `dcr.toml`.
+DCR is a utility for managing C/C++ projects in a Cargo-like style.
 
-Проект находится на стадии MVP. Текущая реализация написана на Python и в будущем будет переписана.
+The current implementation is written in Rust.

+- `dcr-x86_64-apple-darwin`
+- `dcr-aarch64-apple-darwin`
+- `dcr-x86_64-pc-windows-msvc.exe`
+
+## Update
+
+- If DCR was installed from GitHub release assets, `install.sh`, `install.ps1`, or built manually:
+  - use `dcr --update`
+- If DCR is installed via `pacman/AUR`:
+  - update with your package manager: `paru/yay -Syu dcr` or `sudo pacman -Syu dcr`
+  - `dcr --update` detects package-managed installs and asks you to update via package manager
+
+## Quick Start
+
+Create a new project:
 `dcr new hello`
 
-Или инициализировать текущую директорию (директория должна быть пустой):
+Or initialize the current directory (the directory must be empty):
 `dcr init`
 
-Структура проекта:
+Project structure:
-```
+
+```txt
 hello/
 - src/
 - - main.c
 - dcr.toml
 ```
 
-Сборка и запуск проекта:
+Build and run the project:
-`dcr run` или `dcr run --release` - для сбрки с оптимизацией
+`dcr run` or `dcr run --release`
 
-
+## Commands
-## Команды
 
 ### `dcr new <name>`
-Создает проект в текущей директории с указанным именем.
+Creates a project with the specified name in the current directory.
 
 ### `dcr init`
-Создает проект в текущей директории. Имя проекта будет равно имени директории. Директория должна быть пустой.
+Creates a project in the current directory. The project name is taken from the directory name. The directory must be empty.
 
 ### `dcr build [profile]`
-Собирает проект. Если профиль не указан, используется `--debug`.
+Builds the project. If no profile is specified, `--debug` is used.
 
 ### `dcr run [profile]`
-Собирает проект и запускает бинарник. Если профиль не указан, используется `--debug`.
+Builds the project and runs the binary. If no profile is specified, `--debug` is used.
 
-Запуск вручную:
+Run manually:
-`./target/<profile>/main`
+`./target/<profile>/<name>`
 
 ### `dcr clean`
-Удаляет папку `target` в корне проекта.
+Removes the `target` directory in the project root.
 
-## Профили сборки
+## Build Profiles
-Поддерживаются два профиля:
+Two profiles are supported:
-- `--debug` (по умолчанию) — флаги: `-O0 -g -Wall -Wextra -fno-omit-frame-pointer -DDEBUG`
+- `--debug` (default) - built-in flags per compiler
-- `--release` — флаги: `-O3 -DNDEBUG -march=native`
+- `--release` - built-in flags per compiler
 
-## Конфигурация
+Custom flags can be added in `dcr.toml` via `build.cflags` and `build.ldflags`.
-Основной файл проекта — `dcr.toml`. Сейчас он создается автоматически и служит точкой входа для будущих настроек.
+You can also set `build.target` to override the output directory (profile-independent).
+Use `build.kind = "staticlib"` to build a static library instead of a binary.
+`dcr run` is only for `build.kind = "bin"` and will fail for `staticlib`.
 
-Пример `dcr.toml`:
+## Configuration
-```
+The main project file is `dcr.toml`.
+
+Example `dcr.toml`:
+
+```toml
 [package]
 name = "hello"
 version = "0.1.0"
+
+[build]
 language = "c"
+standard = "c11"
 compiler = "clang"
+# Optional custom flags
+cflags = ["-Wall", "-Wextra"]
+ldflags = ["-lm"]
 
 [dependencies]
 ```
 
-## Установка в PATH
+Path dependencies are supported. DCR will resolve them on build and generate `dcr.lock`.
-Чтобы вызывать `dcr` из любой директории, можно сделать symlink в `~/.local/bin`:
-```sh
-ln -s "$PWD/dcr" ~/.local/bin/dcr
-```
-Убедитесь, что `~/.local/bin` находится в `PATH`.
 
-## Пример проекта
+Incremental build note: object files are rebuilt when source `.c/.cpp` files change. Header dependency tracking is not implemented yet.
-`src/main.c` содержит минимальный `Hello, World!`:
-```c
-#include <stdio.h>
 
-int main(void) {
+## Requirements
-    puts("Hello, World!");
+- Rust toolchain (`rustc`, `cargo`) - for building DCR from source
-    return 0;
+- C compiler (`clang`, `gcc`, or 'cl'(msvc))
-}
-```
 
-## Требования
+## Releases
-- C-компилятор (например, `gcc` или `clang`)
+Releases are built automatically via GitHub Actions (`.github/workflows/release.yml`) when a tag matching `v*` is pushed.
-- Python 3.14.2 (для текущей версии DCR)
-- uv (менеджер проекта для Python)
 
-## Статус и планы
+## License
-Проект в стадии MVP. Планируется переписывание на более подходящий язык и расширение функциональности:
+See `LICENSE`.
-- более гибкая конфигурация через `dcr.toml`
-- расширяемые профили сборки
-- менеджер пакетов

+# Introduction
+
+DCR (Dexoron Cargo Realization) is a Cargo-style CLI for C/C++ projects.
+
+Current DCR focuses on a simple, predictable workflow:
+
+- create or initialize a project (`dcr new`, `dcr init`)
+- build with `debug` or `release` profiles (`dcr build`)
+- run binaries (`dcr run`)
+- clean artifacts (`dcr clean`)
+- update the installed binary (`dcr --update`)
+
+## What is implemented in this version
+
+- Project configuration in `dcr.toml` with `[package]`, `[build]`, `[dependencies]`.
+- Recursive source discovery in `src/`:
+  - C: `*.c`
+  - C++: `*.cpp`, `*.cxx`, `*.cc`
+- Compiler selection from `dcr.toml` (`clang`, `gcc`, `cl`, `clang-cl`, etc.).
+- Two build kinds:
+  - `bin` (default)
+  - `staticlib`
+- Optional custom output directory via `build.target`.
+- Path dependencies with include/lib resolution and `dcr.lock` generation.
+
+## Important behavior notes
+
+- `dcr.toml` is required for `build`, `run`, and `clean`.
+- `run` works only with `build.kind = "bin"`.
+- Incremental rebuild currently tracks source file timestamps (not header dependency graphs).
+- Object files are always created under `target/<profile>/obj/`.

+Builds the project in `debug` or `release` profile.
+
+## Usage
+
+```sh
+dcr build
+dcr build --debug
+dcr build --release
+```
+
+## What `build` does
+
+1. Checks that `dcr.toml` exists and is valid.
+2. Reads build settings from `[build]`.
+3. Resolves path dependencies from `[dependencies]`.
+4. Creates required output directories.
+5. Recursively compiles sources from `src/`.
+6. Links final artifact (binary or static library).
+
+## Config values used
+
+- `package.name`
+- `build.compiler`
+- `build.language`
+- `build.standard`
+- `build.kind`
+- `build.target`
+- `build.cflags`
+- `build.ldflags`
+
+## Source selection
+
+- `language = "c"` -> `*.c`
+- `language = "c++" | "cpp" | "cxx"` -> `*.cpp`, `*.cxx`, `*.cc`
+
+## Notes
+
+- The profile is selected from the first argument only.
+- Unknown profile flags return an error.
+- Incremental rebuild is based on source/object mtime comparison.

+## Behavior
+
+- Without arguments: removes entire `target/`.
+- With profile: removes only `target/<profile>/`.

+## Validation
+
+- `dcr.toml` must exist.
+- More than one argument is treated as error.

+
+- Source files are found recursively in `src/` based on `build.language`.

+DCR generates `dcr.lock` when dependency resolution succeeds and at least one dependency exists.

+## What is stored
+
+- Project entry (`name`, `version`, dependency names).
+- One entry per resolved dependency:
+  - `name`
+  - `version` (from dependency `dcr.toml`, fallback `0.0.0`)
+  - `source` (`path+...`)
+  - `checksum` (SHA-256 over dependency files, excluding nested `target/`).

+curl -fsSL https://dcr.dexoron.su/install.sh | bash
+```
+
+Alternative with `wget`:
+
+```sh
+wget -qO- https://dcr.dexoron.su/install.sh | bash
+```
+
+### Windows (PowerShell)
+
+```powershell
+powershell -ExecutionPolicy ByPass -c "irm https://dcr.dexoron.su/install.ps1 | iex"
+```
+
+## Option 2: Build from source
+
+```sh
+git clone https://github.com/dexoron/dcr.git
+cd dcr
+cargo build --release
+mkdir -p ~/.local/bin
+ln -sf "$PWD/target/release/dcr" ~/.local/bin/dcr
+```
+
+## Option 3: Arch Linux (AUR)
+
+```sh
+yay -S dcr
+```
+
+(You can also use `paru` or other AUR helpers.)
+
+## Verify installation
+
+```sh
+dcr --version
+```
+
+Expected format:
+
+```text
+dcr <version> (<target>)
+```
+
+## Update policy
+
+- If DCR was installed from GitHub releases, scripts, or manual build: use `dcr --update`.
+- If DCR is managed by `pacman/AUR`: update via package manager. On Linux, `dcr --update` detects pacman-owned binaries and prints a package-manager hint.

+# Project structure
+
+## Minimal project
+
+```text
+project/
+- dcr.toml
+- src/
+- - main.c
+```
+
+## Typical generated/optional files
+
+```text
+project/
+- dcr.toml
+- dcr.lock
+- src/
+- - ... source files ...
+- target/
+- - debug/
+- - - obj/
+- - - deps/
+- - release/
+- - - obj/
+- - - deps/
+```
+
+## Meaning
+
+- `dcr.toml`: main project configuration.
+- `dcr.lock`: generated lock file for resolved path dependencies.
+- `src/`: recursively scanned source directory.
+- `target/<profile>/obj/`: cached object files for incremental rebuild.
+- `target/<profile>/deps/`: synchronized copies of path dependencies.
+- `target/<profile>/<name>` (or `.exe` on Windows): output for `kind = "bin"`.
+- `target/<profile>/lib<name>.a` (or `<name>.lib` on Windows): output for `kind = "staticlib"`.
+
+If `build.target` is set, the final artifact is written to that custom directory, while object cache still stays in `target/<profile>/obj`.

+dcr build [--debug|--release]
+dcr run [--debug|--release]
+dcr clean [--debug|--release]
+dcr --help
+dcr --version
+dcr --update
+```
+
+## Notes on argument parsing
+
+- Most commands parse profile from the first argument.
+- `new` requires exactly one argument.
+- `init` and `--update` do not accept extra arguments.
+- `clean` accepts at most one argument.
+
+## Exit behavior overview
+
+- Successful command execution returns `0`.
+- Validation/build/runtime errors return non-zero status.

+# FAQ
+
+## What commands are available?
+
+`new`, `init`, `build`, `run`, `clean`, `--help`, `--version`, `--update`.
+
+## Is `dcr.toml` mandatory?
+
+Yes, for `build`, `run`, and `clean`.
+
+## What source files are compiled?
+
+DCR scans `src/` recursively:
+
+- for C: `*.c`
+- for C++: `*.cpp`, `*.cxx`, `*.cc`
+
+## Can I switch compiler?
+
+Yes. Set `build.compiler` in `dcr.toml` (for example `gcc`, `clang`, `cl`, `clang-cl`).
+
+## How does incremental rebuild work?
+
+It compares source file mtime with object file mtime. Header dependency tracking is not implemented yet.
+
+## What does `dcr run` do if build fails?
+
+It tries to run an existing binary from the selected profile; if none exists, it reports an error.
+
+## How do I update DCR?
+
+Use `dcr --update` for non-package-managed installs.
+
+If installed through pacman/AUR, update via package manager.

+# AUR publishing
+
+This repository includes an automated AUR publish workflow:
+- package files: `packaging/aur/dcr/PKGBUILD`, `packaging/aur/dcr/.SRCINFO`
+- workflow: `.github/workflows/aur.yml`
+
+## One-time setup
+
+1. Create the `dcr` package on AUR and initialize its git repository.
+2. Create an SSH key pair for CI.
+3. Add the public key to your AUR account.
+4. Add the private key to GitHub Actions secret `AUR_SSH_PRIVATE_KEY`.
+
+## Release flow
+
+1. Bump project version in `Cargo.toml`.
+2. Push tag `v<version>` (example: `v0.2.2`).
+3. GitHub Actions will:
+- compute source tarball SHA256
+- render `PKGBUILD` and `.SRCINFO`
+- push updates to `ssh://aur@aur.archlinux.org/dcr.git`
