+# Windows File Read Events
+
+A Windows CLI utility to watch the file system for file *read* events.
+
+It writes to the console the file path along with the offset and IO size in bytes.
+
+## Usage
+
+To watch a specific file:
+
+    WinFileReadEvents.exe C:\test\target.txt
+
+Or without any argument to watch system-wide:
+
+    WinFileReadEvents.exe
+
+Press `ctrl+c` to stop watching.
+
+## Output format
+
+Outputs to the stdout any file read event including the file path, along with the offset and read size in the following format:
+
+    >|<offset>|<io_size>|<file_path>
+
+In case of an error, a line will be written to the stdout in the following format:
+
+    x|<error_message>
+
+This utility uses Event Tracing for Windows (ETW) via [`Microsoft.Diagnostics.Tracing.TraceEvent`](https://www.nuget.org/packages/Microsoft.Diagnostics.Tracing.TraceEvent/) package.
