+🖼🗜↩ Unity Texture DeCruncher
+==============================
+
+Following a change in [VRChat Guidelines](https://ask.vrchat.com/t/developer-update-16-march-2023/16950#sdk-warning-improvements-6) about the use of Crunch Compressed textures in projects, I wanted a script to quickly update all texture files in my project to turn off Crunch Compression.
+
+While this feature will likely be built in to future versions of the SDK, this stand-alone script can check every file of your project, regardless of if it is part of your avatar or world currently, and fix the setting in advance.
+
+## ✅ Requirements
+
+* Tested in `Unity 2019.4.31f1`
+
+## 💾 Installation
+
+Download this repo using GIT or by clicking **Code** and then **Download ZIP** above.
+
+In your project, create a folder called `Editor`, and copy the `DeCrunchTextures.cs` file from this repository or the ZIP file into that folder.
+
+**Important:** Unity treats files within folders called *Editor* as special and knows that the script should be run as an Editor Add-On, not part of the project's game code, so don't just stick the file anywhere!
+
+## ▶ Running the Tool
+
+### ⚠ ***Backup your Projects!!!***
+
+If this tool does something unexpected due to a conflict with another script, power loss or bug and corrupts your project, that's on you!
+
+### How to Run
+
+Once imported, an item named **Turn Off Crunch Compression** will be added to Unity's **Tools** menu. Select this menu option to begin the process.
+
+A progress dialog will appear with the number of files to process, if you have a lot of image files in your project and a slow system, this may take some time.
+
+Once the progress dialog is complete, all files will now be set uncrunched. You can now remove the script file from the project by just deleting the script file.
