 # Welcome
 
-For instructions on how to **use Discord History Tracker**, visit the [official website](https://dht.chylex.com).
+All you need to **use Discord History Tracker** is either an up-to-date browser, or the [Discord desktop client](https://discord.com/download). Visit the [official website](https://dht.chylex.com) for instructions.
 
 To **report an issue or suggestion**, first please see the [issues](https://github.com/chylex/Discord-History-Tracker/issues) page and make sure someone else hasn't already created a similar issue report. If you do find an existing issue, comment on it or add a reaction. Otherwise, either click [New Issue](https://github.com/chylex/Discord-History-Tracker/issues/new), or contact me via email [contact@chylex.com](mailto:contact@chylex.com) or Twitter [@chylexmc](https://twitter.com/chylexmc).
 
-If you are interested in **building from source code**, continue reading the [build instructions](#Build-Instructions) below.
+If you are interested in **creating your own version** from the source code, continue reading the [build instructions](#Build-Instructions) below.
-
-This branch is dedicated to the Discord History Tracker desktop app. If you are looking for the older browser-only version, visit the [master-browser-only](https://github.com/chylex/Discord-History-Tracker/tree/master-browser-only) branch.
 
 # Build Instructions
 
+Follow the steps below to create your own version of Discord History Tracker.
+
 ### Setup
 
 Fork the repository and clone it to your computer (if you've never used git, you can download the [GitHub Desktop](https://desktop.github.com) client to get started quickly).
 
-Folder organization:
+Now you can modify the source code:
-* `app/` contains a Visual Studio solution for the desktop app
+* `src/tracker/` contains JS files that are automatically combined into the **tracker bookmark/script**
+* `src/viewer/` contains HTML, CSS, JS files that are then combined into the **offline viewer page**
+* `lib/` contains utilities required to build the project
 * `web/` contains source code of the [official website](https://dht.chylex.com), which can be used as a template when making your own website
 
-To start editing source code for the desktop app, install the [.NET 9 SDK](https://dotnet.microsoft.com/en-us/download/dotnet/9.0), and then open `app/DiscordHistoryTracker.sln` in [Visual Studio](https://visualstudio.microsoft.com/downloads/) or [Rider](https://www.jetbrains.com/rider/).
-
 ### Building
 
-To build a `Debug` version of the desktop app, there are no additional requirements.
+After you've done changes to the source code, you will need to build it. Before that, download and install:
+* (**required**) [Python 3](https://www.python.org/downloads)
+  * Use to run the build script
+* (optional) [Node + npm](https://nodejs.org/en) & command line [uglify-js](https://www.npmjs.com/package/uglify-js)
+  * Not required on Windows
+  * Only required for optional [JS minification](#Minification) on Linux/Mac
 
-To build a `Release` version of the desktop app, follow the instructions for your operating system.
+Now open the folder that contains `build.py` in a command line, and run `python build.py` to create a build with default settings. The following files will be created:
+* `bld/track.js` is the raw tracker script that can be pasted into a browser console
+* `bld/track.html` is the tracker script but sanitized for inclusion in HTML (see `web/index.php` for examples)
+* `bld/viewer.html` is the complete offline viewer
 
-#### Release – Windows (64-bit)
+You can tweak the build process using the following flags:
+* `python build.py --nominify` to disable [minification](#Minification)
 
-1. Install Debian in WSL and open a terminal in the project folder.
+### Minification
-2. Run the `app/build.wsl.sh` script.
-3. Read the [Distribution](#distribution) section below.
 
-Note: The build script expects `dotnet.exe` to be installed in `C:\Program Files\dotnet`.
+The build process automatically minifies JS using `UglifyJS@3`, and CSS using a custom minifier.
 
-#### Release – Other Operating Systems
+* If the `--nominify` flag is used, minification will be completely disabled
-
+* If `uglify-js` is not available from the command line, JS minification will be skipped
-1. Install the `zip` package from your repository.
+  * When building on Windows 64-bit, the build script will use the included Node runner and packages
-2. Run the `app/build.sh` script.
+  * When building on Windows 32-bit, you will need to download [Node 32-bit](https://nodejs.org/en/download) and replace the included one in `lib/`
-3. Read the [Distribution](#distribution) section below.
+  * When building on Linux/Mac, the build script will attempt to find `uglifyjs` in the command line
-
-#### 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 the ASP.NET Core Runtime to be installed.
