+# Automatic conversion of Sigma to Hayabusa rules
+[![python](https://img.shields.io/badge/python-3.8-blue)](https://www.python.org/)
+![version](https://img.shields.io/badge/Platform-Win-green)
+![version](https://img.shields.io/badge/Platform-Lin-green)

+
+You can use `hayabusa.py`, a `sigmac` backend, to automatically convert Sigma rules to Hayabusa rules.
+
+## About Sigma
+
+[https://github.com/SigmaHQ/sigma](https://github.com/SigmaHQ/sigma)
+
+## Settings
+
+hayabusa.py needs `sigmac` from the Sigma repository.
+Before using hayabusa.py, please clone the Sigma repository.
+
+```sh
+git clone https://github.com/SigmaHQ/sigma.git
+```
+
+## Usage
+
+Create an environmental variable `$sigma_path` that points to the Sigma repository and register haybausa as a backend for Sigma:
+
+```sh
+export sigma_path=/path/to/sigma_repository
+cp hayabusa.py $sigma_path/tools/sigma/backends
+```
+
+### Converting a single rule
+
+You can convert a single rule with the following syntax:
+
+```sh
+python3 $sigma_path/tools/sigmac <Target Rule> --config <Config File Name> --target hayabusa
+```
+
+Example:
+```sh
+python3 $sigma_path/tools/sigmac $sigma_path/rules/windows/create_remote_thread/sysmon_cactustorch.yml --config $sigma_path/tools/config/generic/sysmon.yml --target hayabusa > sysmon_cactustorch.yml
+```
+
+### Converting multiple rules
+
+This example will convert all Sigma rules for Windows event logs to hayabusa rules and save them to the current directory.
+
+```sh
+find $sigma_path/rules/windows/* | grep yml | xargs -I{} sh -c 'python $sigma_path/tools/sigmac {} --config $sigma_path/tools/config/generic/sysmon.yml --target hayabusa > "$(basename {})"'
+```

+# SIGMAからHayabusaルールへの自動変換
+[![python](https://img.shields.io/badge/python-3.8-blue)](https://www.python.org/)
+![version](https://img.shields.io/badge/Platform-Win-green)

+
+`hayabusa.py` はSigmaルールをHayabusaルールに変換する`sigmac`のバックエンドです。
+Sigmaの持つ多くの検知ルールをHayabusaのルールセットに追加することでルールを作成する手間を省くことができます。
+
+## Sigmaについて
+
+[https://github.com/SigmaHQ/sigma](https://github.com/SigmaHQ/sigma)
+
+## 環境設定
+
+hayabusa.pyはSigmaリポジトリの中にある`sigmac`を使います。
+事前に任意のディレクトリにSigmaリポジトリをcloneしてください。
+
+```sh
+git clone https://github.com/SigmaHQ/sigma.git
+```
+
+## 使い方
+
+Sigmaレポジトリのパスが書いてある`$sigma_path`という環境変数を設定して、hayabusaをSigmaのbackendとして登録します:
+
+```sh
+export sigma_path=/path/to/sigma_repository
+cp hayabusa.py $sigma_path/tools/sigma/backends
+```
+
+### 単体のルールを変換
+
+以下のシンタクスで単体のルールを変換できます：
+
+```sh
+python3 $sigma_path/tools/sigmac <変換対象ruleの指定> --config <configの指定> --target hayabusa
+```
+
+例：
+```sh
+python3 $sigma_path/tools/sigmac $sigma_path/rules/windows/create_remote_thread/sysmon_cactustorch.yml --config $sigma_path/tools/config/generic/sysmon.yml --target hayabusa > sysmon_cactustorch.yml
+```
+
+### 複数のルールを変換
+
+以下のように、SigmaのすべてのWindowsイベントログルールをhayabusaルールに変換して、カレントディレクトリに保存します：
+
+```sh
+find $sigma_path/rules/windows/* | grep yml | xargs -I{} sh -c 'python $sigma_path/tools/sigmac {} --config $sigma_path/tools/config/generic/sysmon.yml --target hayabusa > "$(basename {})"'
+```

-
-`hayabusaGenerater.py` allows to convert SIGMA rules to Hayabusa ruleset.

-## sigma
-
-[https://github.com/SigmaHQ/sigma](https://github.com/SigmaHQ/sigma)
-
-## Settings
-
-hayabusaGenerator needs `sigmac` from the SIGMA repository.
-Before using hayabusaGenerator, clone the repository.
-
-```sh
-git clone https://github.com/SigmaHQ/sigma.git
-```
-
-## Quickstart
-
-Regist haybausa for SIGMA's backend.
-
-```sh
-export sigma_path=/path/to/sigma_repository
-cp hayabusaGenerater.py $sigma_path/tools/sigma/backends
-```
-
-### Convert Single Rule
-
-```sh
-python3 $sigma_path/tools/sigmac <Target Rule> --config <config Name> --target hayabusa
-```
-
-Sample
-```sh
-python3 $sigma_path/tools/sigmac $sigma/rules/windows/create_remote_thread/sysmon_cactustorch.yml --config $sigma_path/tools/config/generic/sysmon.yml --target hayabusa > sysmon_cactustorch.yml
-```
-
-### Convert Multiple Rules
-
-This is a command sample that creates a rule file from the specified directory in the current directory.
-
-```sh
-find $sigma/rules/windows/* | grep yml | xargs -I{} sh -c 'python $sigma/tools/sigmac {} --config $sigma/tools/config/generic/sysmon.yml --target hayabusa > "$(basename {})"'
