+## DCR_COMPILER
+
+Overrides the compiler for all languages. **Highest priority.**
+
+```bash
+export DCR_COMPILER=clang
+dcr build
+```
+
+Compiler resolution priority:
+
+1. `DCR_COMPILER` (env)
+2. `DCR_CC` / `DCR_CXX` / `DCR_AS` (env)
+3. `[toolchain]` (dcr.toml)
+4. `build.compiler` (dcr.toml)
+5. `PATH`
+
+## DCR_CC / DCR_CXX / DCR_AS
+
+Per-language override (lower priority than `DCR_COMPILER`, higher than `[toolchain]`).
+
+```bash
+export DCR_CC=gcc-14
+export DCR_CXX=g++-14
+export DCR_AS=arm-linux-gnueabihf-as
+```

+
+```bash
+export DCR_LD=ld.lld
+export DCR_AR=llvm-ar

+
+```bash
+export DCR_DEBUG=1
+dcr build
+```
+
