+
+### Optional: CUDNN 8.6
+
+This step is optional but can improve the learning speed for NVidia 4090 owners...
+
+Due to the filesize I can't host the DLLs needed for CUDNN 8.6 on Github, I strongly advise you download them for a speed boost in sample generation (almost 50% on 4090) you can download them from here: https://b1.thefileditch.ch/mwxKTEtelILoIbMbruuM.zip
+
+To install simply unzip the directory and place the cudnn_windows folder in the root of the kohya_diffusers_fine_tuning repo.
+
+Run the following command to install:
+
+```
+python .\tools\cudann_1.8_install.py
+```
+
+## Upgrade
+
+When a new release comes out you can upgrade your repo with the following command:
+
+```powershell
+cd kohya_ss
+git pull
+.\venv\Scripts\activate
+pip install --upgrade -r requirements.txt
+```
+
+Once the commands have completed successfully you should be ready to use the new version.
+
+## Launching the GUI
+
+To run the GUI you simply use this command:
+
+```
