-- if you get out of memory errors and your video-card has a low amount of VRAM (4GB), create a file called `webui.custom.bat` (in the same folder as `webui.bat`) and write inside of it `webui.bat --medvram` (see below for other possible options). _From now on, **instead** of running `webui.bat`, you should run `webui.custom.bat`_
-- installer creates python virtual environment, so none of installed modules will affect your system installation of python if you had one prior to installing this.

If you choose to install for a different version of python, editing `webui.bat` to have `set REQS_FILE=requirements.txt` instead of `set REQS_FILE=requirements_versions.txt` may help (but I still recommend you to just use the recommended version of python).
-- if you feel you broke something and want to reinstall from scratch, delete directories: `venv`, `repositories`.
+It's possible to edit `set COMMANDLINE_ARGS=` line in `webui.bat` to run the program with different command line arguments, but that may lead
+to inconveniences when the file is updated in the repository.
 
-### Google collab
+The recommndended way is to use another .bat file named anything you like, set the parameters you want in it, and run webui.bat from it.
+A `webui-user.bat` file included into the repository does exactly this.

+Another example, this file will run the program with custom python path, a different model named `a.ckpt` and without virtual environment:
+
+```commandline

+set PYTHON=b:/soft/Python310/Python.exe
+set VENV_DIR=-
+set COMMANDLINE_ARGS=--ckpt a.ckpt

 ### What options to use for low VRAM video-cards?
-Use command line options by creating or modifying `webui.settings.bat` in the root folder (same place as webui.bat), adding a line with `set COMMANDLINE_ARGS=`, and adding the settings at the end of that line.
-You can, through command line arguments, enable the various optimizations which sacrifice some/a lot of speed in favor of using less VRAM. To do so, simply create (or modify it, if you've previously created it) a file called `webui.settings.bat` _in the same folder_ as `webui.bat`. Inside there should only be one line: `webui.bat <arguments>`
-For example, `webui.bat --medvram --opt-split-attention`.
+You can, through command line arguments, enable the various optimizations which sacrifice some/a lot of speed in favor of
