-# developtools_syscap_codec
+# System Capability Encoder and Decoder Tools
-#### Description
-{**When you're done, you can delete the content in this README and update the file with details for others getting started with your repository**}
+SysCap(SystemCapability) encoder and decoder tools common usage scenarios as follow:
-#### Software Architecture
-Software architecture description
+1.Device development: After deivce developer assembling components completed, building system will generate SysCap list and collect vendor ID, API version as PCID encoder inputs.
-#### Installation
+2.APP development: IDE collect APP required SysCap and API verssion as in RPCID encoder input. And IDE will decode PCID to device SysCap list when it imported.
-1. xxxx
-2. xxxx
-3. xxxx
+3.APP distribution: RPCID/PCID decoder used for APP distribution procedure, APP store will check whether device's SysCap satisfy APP required SysCap.
-#### Instructions
+4.APP installation: Bundle tools used RPCID decoder to decode APP required SysCap list.
-1. xxxx
-2. xxxx
-3. xxxx
+## Architecture
-#### Contribution
+SysCap codec tools has two components:
-1. Fork the repository
-2. Create Feat_xxx branch
-3. Commit your code
-4. Create Pull Request
+1. syscap_tool:Binary used for APP developing, IDE invoker RPCID encoder and PCID decoder when APP compiling and PCID importing.
+2. syscap_tool_shared:Shared library used for device developing and APP installing.
-#### Gitee Feature

+
+### API
+
+PC tools, no API provided.
+
+### Building Manually
+
+syscap_tool binary building steps as follow:
+
+1. Build commands:SysCap tools binary building and installation will be tiggered by SDK compiling procedure. How to build SDK please refer to https://gitee.com/openharmony/build/blob/master/README_zh.md.
+
+2. Building cmd should be adjust for host platform as same as SDK compiling, the archive will in corresponding platform directoty. Note: Ubuntu host only avaiable for windows/linux building, MacOs binary should building on MacOs host.
+
+### Downloading Binary
+
+[1.Downlaod SDK(recommonded))]
+
+Download daily builds(http://ci.openharmony.cn/dailybuilds) which included SDK.
+
+[3.Supported Host]
+
+Windows x86_64/Linux x86_64/Darwin x86_64
+
+### Help
+
+SysCap tools usually integrate to IDE, APP store and bundle tools. Follow instructions for debugging manually:
+
+./syscap_tool -h or ./syscap_tool --help:
+
+./syscap_tool -R/P -e/d -i filepath [-o outpath]
+
+-h, --help : how to use
+
+-R, --RPCID : encode or decode RPCID
+
+-P, --PCID : encode or decode PCID
+

+-o outpath, --input outpath : output path
+
+### Release Note
+
+v1.0.0 2022-3-8 first release, SysCap codec supported for Windows/Linux/Mac host.
