 **Important:** These instructions are for the developers of this project, not for users! The users should use the pre-created zip files for installation.
 
-This guide explains how to create the zip files that users will use for installing.
+Just distribute the `install.bat` or `install.sh` file.
 
-The installer zip contains two files: the script, and the micromamba binary.
-
-Micromamba is a single ~8mb binary file, that acts like a package manager (drop-in replacement for conda).
-
-# Download micromamba from:
-* Windows x64: `curl -Ls https://micro.mamba.pm/api/micromamba/win-64/latest | tar -xvj bin/micromamba_win_x64.exe`
-
-* Linux x64: `curl -Ls https://micro.mamba.pm/api/micromamba/linux-64/latest | tar -xvj bin/micromamba_linux_x64`
-* Linux arm64: `curl -Ls https://micro.mamba.pm/api/micromamba/linux-aarch64/latest | tar -xvj bin/micromamba_linux_arm64`
-
-* Mac x64: `curl -Ls https://micro.mamba.pm/api/micromamba/osx-64/latest | tar -xvj bin/micromamba_mac_x64`
-* Mac arm64 (M1/Apple Silicon): `curl -Ls https://micro.mamba.pm/api/micromamba/osx-arm64/latest | tar -xvj bin/micromamba_mac_arm64`
-
-The download link provides tar.bz2 files.
-
-(source https://mamba.readthedocs.io/en/latest/installation.html)
-
-# Create the installer
-Create the following folder structure, and zip it up.
-
-For Linux/Mac: Make sure the `chmod u+x` permission is granted to `install.sh` and the corresponding `micromamba` binary.
-
-### Windows x64:
-```
-.\install.bat
-.\installer_files\micromamba_win_x64.exe
-```
-
-### Linux x64:
-```
-.\install.sh
-.\installer_files\micromamba_linux_x64
-```
-
-### Linux arm64:
-```
-.\install.sh
-.\installer_files\micromamba_linux_arm64
-```
-
-### Mac x64:
-```
-.\install.sh
-.\installer_files\micromamba_mac_x64
-```
-
-### Mac arm64 (M1/Apple Silicon):
-```
-.\install.sh
-.\installer_files\micromamba_mac_arm64
-```
+Running that file will download the invokeAI repository into the same folder as the script, and install the required dependencies.
