+# Hitman Crash Inspector
+
+
+
+Hitman Crash Inspector is a terminal-based tool for decrypting and inspecting the `crash_metrics.dat` files from [HITMAN World of Assassination](https://ioi.dk/hitman). The tool provides detailed information on the crash described inside the crash metrics file.
+
+## Usage
+To use the GUI, simply download the latest release from the [releases]() page and extract the contents of the zip file. You can then use the program by running the `hitman-crash-inspector.exe` file. The tool will automatically open a terminal, and you can select a `crash_metrics.dat` file manually.
+
+### command-line arguments
+You can use the tool in a command-line by passing arguments to the `hitman-crash-inspector.exe` file. The following arguments are available:
+
+```
+Usage: hitman-crash-inspector.exe [--tick-rate ] [--enhanced-graphics ] [--metrics-path ]
+
+Options:

+ --enhanced-graphics
+ whether unicode symbols are used to improve the overall look of the app (default: true)
+ --metrics-path
+ path to the metrics file
+ --help

+hitman-crash-inspector.exe --metrics-path "C:\Users\agent_47\AppData\Roaming\IO Interactive\HITMAN3\crash_metrics.dat"
