+# Release Candidate Testing
+
+If you are on SteamOS make sure you are in `Desktop Mode` before you begin, you must also have set a sudo password.
+
+## Step 1: Take some Backups
+
+First take some backups:
+
+- Make a copy of `~/.var/app/net.retrodeck.retrodeck/` folder and name it `old.net.retrodeck.retrodeck`
+- Make a full backup or partial backups of the retrodeck folder normally under `~/retrodeck` or sdcard/other drive. Generally a very few things would target the roms folder, but the other folders could be targeted for various scripts. Our recommendation would be to backup the full folder, but as a tester you can decide how much you want to risk.
+
+## Step 2: Download the Cooker
+
+- Download the latest cooker release from: https://github.com/XargonWan/RetroDECK-cooker/releases/latest to your download folder
+- Make a note of the version id, is a randomly generated word written like cooker-0.8.0b-**HelloWorld**, in this example it's "HelloWorld"
+
+## Step 3: Terminal
+
+Open the terminal and type:
+
+- `flatpak remove net.retrodeck.retrodeck` and press (y) yes to remove RetroDECK.
+- `flatpak install --user --bundle --noninteractive -y "~/Downloads/RetroDECK-cooker.flatpak"` this will install RetroDECK Cooker, you will need to type your sudo password twice.
+- After the installation is complete type: `flatpak run --command=sh net.retrodeck.retrodeck` followed by `retrodeck`.
+
+IMPORTANT: please check if you see the message `"In version 0.8.0b, the following changes were made that required config file updates/reset or other changes to the filesystem:"` as this means that the post update is running, this is crucial for RetroDECK's upgrade.
+
+## Step 4: Upgrade
+
+- Press the upgrade button and keep the installation moving until all the steps are complete.
+- RetroDECK will then launch, quit it and save all the data from the terminal in a text file (in case we need to analyze it).
+
+## Step 5: Start testing
+
+On the SteamOS return to `Game Mode` for this step.
+
+Feel free to test all the new features of 0.8.0b and report any issues.
+
+- Configurator
+- External Controller Profiles
+- Emulators / Engines
+
+All logs will be saved in the new `retrodeck/logs` folder
+
+Thank you! ❤️
