+PM> Install-Package CefSharp.WinForms -Version 67.0.0

-Note that some pre-release builds of CefSharp are not available on NuGet. To correctly restore packages in that case, open **Package Manager Settings**, and add `https://www.myget.org/F/cefsharp/api/v3/index.json` to the list of package sources.

 ### Debug
 
 The `Debug` configuration uses a separate data folder by default (`%LOCALAPPDATA%\TweetDuckDebug`) to avoid affecting an existing installation of TweetDuck. You can modify this by opening **TweetDuck Properties** in Visual Studio, clicking the **Debug** tab, and changing the **Command line arguments** field.
 
-While debugging, opening the main menu and clicking **Reload browser** automatically rebuilds all resources in the `Resources/Scripts` and `Resources/Plugins` folders. This allows editing HTML/CSS/JS files and applying the changes without restarting the program, but it will cause a short delay between browser reloads.

 ### Installers
 
 TweetDuck uses **Inno Setup** for installers and updates. First, download and install [InnoSetup QuickStart Pack](http://www.jrsoftware.org/isdl.php) (non-unicode; editor and encryption support not required) and the [Inno Download Plugin](https://code.google.com/archive/p/inno-download-plugin).
 
 Next, add the Inno Setup installation folder (usually `C:\Program Files (x86)\Inno Setup 5`) into your **PATH** environment variable. You may need to restart File Explorer for the change to take place.
 
-Now you can generate installers after a build by running `bld/RUN BUILD.bat`. Note that this will only package the files, you still need to run the [release build](#release) in Visual Studio!
+Now you can generate installers by running `bld/GEN INSTALLERS.bat`. Note that this will only package the files, you still need to run the [release build](#release) in Visual Studio!
 
 After the window closes, three installers will be generated inside the `bld/Output` folder:
 * **TweetDuck.exe**
   * This is the main installer that creates entries in the Start Menu & Programs and Features, and an optional desktop icon
 * **TweetDuck.Update.exe**
   * This is a lightweight update installer that only contains the most important files that usually change across releases
-  * It will automatically download and apply the full installer if the user's current version of CEF does not match (the download link is in `gen_upd.iss` and points to this repository by default)
+  * It will automatically download and apply the full installer if the user's current version of CEF does not match
 * **TweetDuck.Portable.exe**
   * This is a portable installer that does not need administrator privileges
   * It automatically creates a `makeportable` file in the program folder, which forces TweetDuck to run in portable mode
 
+The installers are built for GitHub Releases, where the main and portable installers can download and install Visual C++ if it's missing, and the update installer will download and apply the full installer when needed. If you plan to distribute your own installers via GitHub, you can change the variables in the installer files (`.iss`) and in the update system to point to your repository, and use the power of the existing update system.
+
 #### Notes
 
 > When opening **Batch Build**, you will also see `x64` and `AnyCPU` configurations. These are visible due to what I consider a Visual Studio bug, and will not work without significant changes to the project. Manually running the `Resources/PostCefUpdate.ps1` PowerShell script modifies the downloaded CefSharp packages, and removes the invalid configurations.
 
-> There is a small chance running `RUN BUILD.bat` immediately shows a resource error. If that happens, close the console window (which terminates all Inno Setup processes and leaves corrupted installers in the output folder), and run it again.
+> There is a small chance running `GEN INSTALLERS.bat` immediately shows a resource error. If that happens, close the console window (which terminates all Inno Setup processes and leaves corrupted installers in the output folder), and run it again.
 
-> Running `RUN BUILD.bat` uses about 400 MB of RAM due to high compression. You can lower this to about 140 MB by opening `gen_full.iss` and `gen_port.iss`, and changing `LZMADictionarySize=15360` to `LZMADictionarySize=4096`.
