+### What is CTH++
+
+## Usage
+
+```text
+Usage: cth++ [options]
+Options:
+	-h, --help - show this message
+	-f, --file=<file> - input json file
+	-o, --output=<file> - output file
+	-w, --working=<dir> - working directory
+	--std <std> - c++ standard
+	--cmake-target-current-build <target> - current build target
+	--global-namespace <name> - global namespace
+	--debug - debug mode
+	--release - release mode
+	--development - development mode
+	--production - production mode
+```
+
+# Example
+
+```shell
+$ cth++ -f=config.json -o=config.h
