# Who Is This For
- Anyone who wants Codex custom skins to level up their interface's look
- Anyone who wants to create a personal-brand, character-themed, or brand-exclusive skin
- Anyone willing to spend a little time replacing assets
If you want to get started quickly, just use a ready-made theme; if you're chasing ultimate personalization, keep reading the customization section.
# Bottom Line First: Custom Codex Skins Only Take 3 Steps
- Let Codex AI complete the project installation
- Close Desktop and run the installation script
- Restart and replace personalized assets
The whole process is straightforward — the tricky part is not knowing where to start the first time. This article breaks it down for you completely.
Step 1: Let Codex AI Automatically Install Dream Skin
Open Codex Desktop, send it the repository link directly, and let the AI complete the installation and configuration according to the project instructions.
Recommended prompt:
[Fei-Away/Codex-Dream-Skin](https://github.com/Fei-Away/Codex-Dream-Skin)
帮我安装这个 Codex 自定义皮肤项目，并详细说明如何设置 Codex Desktop 主题。
This step lets the AI help you sort out the repository, dependencies, and script relationships, avoiding mistakes from manual operation.
Step 2: Close Codex Desktop and Run the Installation Script
Important: before installing, you must fully close Codex Desktop.
Enter the project directory, right-click and run install-dream-skin.ps1 with PowerShell.
The script will automatically take over Codex Desktop's skin files. If it prompts you to confirm a path or permissions during the process, just follow the prompts. For open-source projects, it's a good idea to read the code first before executing.
Step 3: Launch to Verify and Check the Skin Effect
After installation is complete, restart Codex Desktop as prompted.
On success, the interface style will visibly change. You can continue replacing elements like the background image and sidebar textures.
Step 4: Use AI to Generate Personalized Codex Theme Assets
Don't want to use the default template? Just have Codex AI generate exclusive assets for you.
Example recommended prompt:
我是一个ikun，帮我生成一套适合 Codex 自定义皮肤的完整素材包。
要求：宽屏背景、侧栏纹理、装饰边角、角色元素、统一图标风格，整体暗黑高对比，适合桌面端使用。
Once generated, replace the files in the corresponding folders one by one.
Design tip: the background can be rich, but foreground controls must stay clear and high-contrast, to ensure input and reading aren't affected.
Common Issues and Pitfall Avoidance
- Script path errors causing installation failure
- Not closing Codex Desktop, so the skin doesn't take effect
- Assets too busy, covering the input area
- Image subject too small, blurry after scaling
- Modifying too many elements at once, making issues hard to troubleshoot
We recommend changing only 1-2 elements at a time and testing incrementally.
How to Restore the Default Skin
Back up the original files before installing. To restore, you can:
- Delete the replaced assets and switch back to the original files
- Re-run the installation script's restore option
- Or simply reinstall Codex Desktop
For specific methods, refer to the project's GitHub README.
Summary: Getting Started with Codex Custom Skins
Changing your Codex Desktop theme doesn't have a high bar: first run through the flow with a ready-made theme, then gradually use AI to generate personalized assets, and you'll create a one-of-a-kind work interface. Whether for daily use or showing off your personal style, Codex Dream Skin is highly recommended.
