 #### Release – Windows (64-bit)
 
-1. Install [Python 3](https://www.python.org/downloads), and ensure the `python` executable is in your `PATH`
-2. Install [Powershell 5](https://docs.microsoft.com/en-us/powershell/scripting/install/installing-powershell-on-windows) or newer (on Windows 10, the included version of Powershell should be enough)

-The `lib/` folder contains an installation of [Node](https://nodejs.org/en) and [uglify-js](https://www.npmjs.com/package/uglify-js), which are used to minify the tracking script. This installation will only work on 64-bit Windows; building on 32-bit Windows is not supported, but you can try.
+1. Install [Powershell 5](https://docs.microsoft.com/en-us/powershell/scripting/install/installing-powershell-on-windows) or newer (on Windows 10, the included version of Powershell should be enough)
 
 Run the `app/build.bat` script, and read the [Distribution](#distribution) section below.
 
 #### Release – Other Operating Systems
 
-1. Install [Python 3](https://www.python.org/downloads), and ensure the `python` executable exists and launches Python 3
-   - On Debian and derivatives, you can install `python-is-python3`
-   - On other distributions, you can create a link manually, for ex. `ln -s /usr/bin/python3 /usr/bin/python`
-   - If you don't want `python` to mean Python 3, then edit `Desktop.csproj` and change `python` to `python3`
-2. Install [Node + npm](https://nodejs.org/en)
-3. Install [uglify-js](https://www.npmjs.com/package/uglify-js) globally (`npm install -g uglify-js`)

 #### Distribution
 
-The mentioned build scripts will prepare `Release` builds ready for distribution. Once the script finishes, the `app/bin` folder will contain self-contained executables for each major operating system, and a portable version that works on all other systems but requires .NET 5 to be installed.

-Note that when building on Windows, the generated `.zip` files for Linux and Mac will not have correct file permissions, so it will not be possible to run them by double-clicking `DiscordHistoryTracker`. I tried using Python to re-create the archives with correct file permissions, but found that Linux `zip` tools could not see them. The only working solution is building the Windows + portable version on Windows, and Linux + Mac version on Linux.
+Note that when building on Windows, the generated `.zip` files for Linux and Mac will not have correct file permissions, so it will not be possible to run them by double-clicking the executable. Since .NET 8 fixed several issues with publishing Windows executables on Linux, I recommend using Linux to build the app for all operating systems.
