-## Building for your target ARM CPU
-
 ```bash
 docker build -f docker/Dockerfile.cpu \
-        --platform=linux/arm64 \
-        --build-arg VLLM_CPU_ARM_BF16=<false (default)|true> \
-        --tag vllm-cpu-env \
-        --target vllm-openai .
-```
+        --tag vllm-cpu-env .
 
-!!! note "Auto-detection by default"
-    By default, ARM CPU instruction sets (BF16, NEON, etc.) are automatically detected from the build system's CPU flags. The `VLLM_CPU_ARM_BF16` build argument is used for cross-compilation:
-
-    - `VLLM_CPU_ARM_BF16=true` - Force-enable ARM BF16 support (build with BF16 regardless of build system capabilities)
-    - `VLLM_CPU_ARM_BF16=false` - Rely on auto-detection (default)
-
-### Examples
-
-**Auto-detection build (native ARM)**
-
-```bash
-# Building on ARM64 system - platform auto-detected
-docker build -f docker/Dockerfile.cpu \
-        --tag vllm-cpu-arm64 \
-        --target vllm-openai .
-```
-
-**Cross-compile for ARM with BF16 support**
-
-```bash
-# Building on ARM64 for newer ARM CPUs with BF16
-docker build -f docker/Dockerfile.cpu \
-        --build-arg VLLM_CPU_ARM_BF16=true \
-        --tag vllm-cpu-arm64-bf16 \
-        --target vllm-openai .
-```
-
-**Cross-compile from x86_64 to ARM64 with BF16**
-
-```bash
-# Requires Docker buildx with ARM emulation (QEMU)
-docker buildx build -f docker/Dockerfile.cpu \
-        --platform=linux/arm64 \
-        --build-arg VLLM_CPU_ARM_BF16=true \
-        --build-arg max_jobs=4 \
-        --tag vllm-cpu-arm64-bf16 \
-        --target vllm-openai \
-        --load .
-```
-
-!!! note "ARM BF16 requirements"
-    ARM BF16 support requires ARMv8.6-A or later (FEAT_BF16). Supported on AWS Graviton3/4, AmpereOne, and other recent ARM processors.

-    Instead of `--privileged=true`, use `--cap-add SYS_NICE --security-opt seccomp=unconfined` for better security.
