 This is in-flux, but one way to get a development environment running for editing the UI of this project is:
 (swap `.sh` or `.bat` in instructions depending on your environment, and be sure to adjust any paths to match where you're working)
 
-1) `git clone` the repository, e.g. to `/projects/stable-diffusion-ui-repo`
-2) Download the pre-built end user archive from the link on github, and extract it, e.g. to `/projects/stable-diffusion-ui-archive`
-3) `cd /projects/stable-diffusion-ui-archive` and run the script to set up and start the project, e.g. `start.sh`
-4) Check you can view and generate images on `localhost:9000`
-5) Close the server, and edit `/projects/stable-diffusion-ui-archive/scripts/on_env_start.sh`
-6) Comment out the lines near the bottom that copies the `files/ui` folder, e.g:
+1) Install the project to a new location using the [usual installation process](https://github.com/cmdr2/stable-diffusion-ui#installation), e.g. to `/projects/stable-diffusion-ui-archive`
+2) Start the newly installed project, and check that you can view and generate images on `localhost:9000`
+3) Next, please clone the project repository using `git clone` (e.g. to `/projects/stable-diffusion-ui-repo`)
+4) Close the server (started in step 2), and edit `/projects/stable-diffusion-ui-archive/scripts/on_env_start.sh` (or `on_env_start.bat`)

 ## Development environment for Installer changes
 Build the Windows installer using Windows, and the Linux installer using Linux. Don't mix the two, and don't use WSL. An Ubuntu VM is fine for building the Linux installer on a Windows host.
 
-1. Install Miniconda 3 or Anaconda.
-2. Install `conda install -c conda-forge -y conda-pack`
-3. Open the Anaconda Prompt. Do not use WSL if you're building for Windows.
-4. Run `build.bat` or `./build.sh` depending on whether you're in Windows or Linux.
-5. Compress the `stable-diffusion-ui` folder created inside the `dist` folder. Make a `zip` for Windows, and `tar.xz` for Linux (smaller files, and Linux users already have tar).
-6. Make a new GitHub release and upload the Windows and Linux installer builds.
+1. Run `build.bat` or `./build.sh` depending on whether you're in Windows or Linux.
+2. Make a new GitHub release and upload the Windows and Linux installer builds created inside the `dist` folder.
