 # runpythonvirtual
 It’s a basic Nim wrapper to run Python scripts with a hardcoded interpreter in the same shell while forwarding arguments transparently.
+
+# 📜 Description of the Current Program
+
+This Nim program is a simple Python launcher:
+
+### Hardcoded Executable Path
+
+The path to the Python interpreter inside the virtual environment is written directly into the code.
+
+```
+Example (Windows):
+
+const exePath = r"C:\Programs\PythonVirtualEnv\tuivirtual\Scripts\python.exe"
+```
+
+### Command-Line Argument Forwarding
+
+When you run the Nim program with arguments, it forwards them to the Python executable.
+
+```
+Example:
+
+runpython.exe myscript.py arg1 arg2
+```
+
+internally runs:
+```
+C:\Programs\PythonVirtualEnv\tuivirtual\Scripts\python.exe myscript.py arg1 arg2
+```
+
+### Process Execution in Current Shell
+
+- It uses ```startProcess(exePath, args=args, options={poParentStreams})```.
+
+- This runs the Python script inside the same shell session as the Nim program, sharing stdin/stdout/stderr.
+
+- That means no new window/terminal is opened; it just executes inline.
+
+### Output Handling
+
+- Because {poParentStreams} is used, all Python output is visible in the same console window.
+
+- The program waits for Python to finish, then prints "Process finished.".
+
+### ⚡ Example Run
+```
+nim c -r runpython.nim myscript.py
+```
