+### Qemu ARM Virt HOWTO
+
+#### 1. Brief introduction 
+`arm/` subdirectory contains part of the OpenHarmony LiteOS demonstration support for Qemu ARM Virtual Platform,
+here called *virt*.  
+ARM Virtual platform is a `qemu-system-arm` machine target that provides emulation
+for a generic, ARM-based board. Virt is somehow configurable, for example
+user can select core type, number of cores, amount of memory, security features
+as well as, to some extent, on-chip device configuration.
+
+Introduced functionality adds support for Cortex-A7 (1 CPU with security extensions),
+GICv2, 1024MB memory virtual platform.  
+
+Note: System memory size is hard-coded to 32MB. 
+
+#### 2. Setting up environment
+
+Refer to HOWTO guide: [Setting up a development environment](https://gitee.com/openharmony/docs/blob/master/docs-en/quick-start/setting-up-a-development-environment-1.md)
+
+#### 3. Code acquisition
+
+Refer to HOWTO guide: [Code acquisition](https://gitee.com/openharmony/docs/blob/master/docs-en/get-code/source-code-acquisition.md)  
+Note: One can use `repo` to fetch code in a straightforward manner.
+
+#### 4. Building from sources
+
+While being in the fetched source tree root directory, please type:
+```
+./build.py qemu_arm_virt_ca7 -b debug
+```
+This will build `OHOS_Image` for Qemu ARM virt machine.  
+Note: "debug" type of build is currently a default type since, as for other supported debug targets, it incorporates Shell app.
+      There is no release build available at this time.  
+
+After build is finished, the resulting image can be found in:
+```
+out/qemu_arm_virt_ca7/OHOS_Image
+```
+#### 5. Running image in Qemu
+
+a) If not installed, please install `qemu-system-arm`  
+For details, please refer to the HOWTO: [Qemu installation](https://www.qemu.org/download/)   
+
+Note: The introduced functionality was tested on virt-5.1 target machine. It is not guaranteed to work with any other version
+      so make sure that your qemu-system-arm emulator is up to date.
+
+b) Run `qemu-system-arm`  
+
+```
+qemu-system-arm -M virt,gic-version=2,secure -cpu cortex-a7 -smp cpus=1 -nographic -kernel ./out/qemu_arm_virt_ca7/OHOS_Image -m 1G
+```
+
+
+```
+Explanation for our system configuration:  
+-M virt,gic-version=2,secure : runs ARM virtual platform with ARM Generic Interrupt Controller version 2 and security extensions enabled
+-smp cpus=1                  : defines 1 CPU system
+-m 1G                        : defines system memory to be 1024MB. This limitation will be removed in the future but now,
+                               more memory will simply not be visible in the system.
+```
+
+
+Note: OHOS build target name `qemu_arm_virt_ca7` is derived from the above mentioned command.
