 ## Setup
-Linux users must build [wwylele/save3ds](https://github.com/wwylele/save3ds) and place `save3ds_fuse` in `bin/linux`. Install [rust using rustup](https://www.rust-lang.org/tools/install), then compile with: `cargo build --release --no-default-features`. The compiled binary is located in `target/release/save3ds_fuse`, copy it to `bin/linux`.
+Linux users must build [wwylele/save3ds](https://github.com/wwylele/save3ds) and place `save3ds_fuse` in one of these places:
+* A directory in `PATH`
+* In `custominstall/bin/linux`
+* Set the environment variable `CUSTOM_INSTALL_SAVE3DS_PATH` to the `save3ds_fuse` binary
 
 movable.sed is required and can be provided with `-m` or `--movable`.

 ### GUI Setup
 Linux users may need to install a Tk package:
 - Ubuntu/Debian: `sudo apt install python3-tk`
-- Manjaro/Arch: `sudo pacman -S tk`
-
-Install the requirements listed in "Summary", then run `ci-gui.py`.

 ## Development
 
 ### Building Windows standalone
 
-Using a 32-bit version of Python is recommended to build a version to be distributed.
-
-A [virtual environment](https://packaging.python.org/guides/installing-using-pip-and-virtual-environments/#creating-a-virtual-environment) is recommended to isolate the packages from system directories. The build script `make-standalone.bat` assumes that the dependencies are in PATH.
-
-Install the dependencies, plus cx-Freeze. In a virtual environment, the specific Python version doesn't need to be requested.
-```batch
-pip install cx-freeze -r requirements-win32.txt
-```
-
-Copy `custom-install-finalize.3dsx` to the project root, this will be copied to the build directory and included in the final archive.
-
-Run `make-standalone.bat`. This will run cxfreeze and make a standalone version at `dist\custom-install-standalone.zip`
