+
+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 <tick-rate>] [--enhanced-graphics <enhanced-graphics>] [--metrics-path <metrics-path>]
+
+Options:
+  --tick-rate       
+        time in ms between two ticks (default: 150)
+  --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            
+        display usage information
+```
+For example, to open a crash_metrics.dat file located at `C:\Users\agent_47\AppData\Roaming\IO Interactive\HITMAN3\crash_metrics.dat` and enable live update, you can use the following command:
+
+```cmd
+hitman-crash-inspector.exe --metrics-path "C:\Users\agent_47\AppData\Roaming\IO Interactive\HITMAN3\crash_metrics.dat"
+```
