 # Build Instructions
 
-The program was built using Visual Studio 2017. After opening the solution, make sure you have **CefSharp.WinForms** and **Microsoft.VC120.CRT.JetBrains** included - if not, download them using NuGet.
+### Setup
+
+The program was built using Visual Studio 2017. Before opening the solution, please make sure you have the following workloads and components installed (optional components that are not listed can be deselected to save space):
+* **.NET desktop development**
+  * .NET Framework 4 – 4.6 development tools
+* **Desktop development with C++**
+  * VC++ 2017 v141 toolset
+
+After opening the solution, download the following NuGet packages by right-clicking on the solution and selecting **Restore NuGet Packages**, or manually running these commands in the **Package Manager Console**:
 ```
 PM> Install-Package CefSharp.WinForms -Version 57.0.0
 PM> Install-Package Microsoft.VC120.CRT.JetBrains
 ```
 
-When building the `Release` configuration, the folder will only contain files intended for distribution (no debug symbols or other unnecessary files). You may package the files yourself, or use `bld/RUN BUILD.bat` to generate installer files using Inno Setup (make sure the Inno Setup binaries are on your PATH).
+### Debug
 
-Built files are available in **bin/x86**, installer files are generated in **bld/Output**. If you decide to release a custom version publicly, please make it clear that it is not the original TweetDuck. 
+It is recommended to create a separate data folder for debugging, otherwise you will not be able to run TweetDuck while debugging the solution.
+
+To do that, open **TweetDuck Properties**, click the **Debug** tab, make sure your **Configuration** is set to `Active (Debug)` (or just `Debug`), and insert this into the **Command line arguments** field:
+```
+-datafolder TweetDuckDebug
+```
+
+### Build
+
+To make a release build of TweetDuck, open **Batch Build**, tick all `Release` configurations except for the `UnitTest` project (otherwise the build will fail), and click **Rebuild**. Check the status bar to make sure it says **Rebuild All succeeded**; if not, see the [Troubleshooting](#troubleshooting) section.
+
+After the build succeeds, the `bin/x86/Release` folder will contain files intended for distribution (no debug symbols or other unnecessary files). You may package these files yourself, or see the [Installers](#installers) section for automated installer generation.
+
+If you decide to release a custom version publicly, please make it clear that it is not an official release of TweetDuck.
+
+### Troubleshooting
+
+There are a few quirks in the build process that may catch you off guard:
+
+- **Plugin files are not updated automatically**
+  - Since official plugins (`Resources/Plugins`) are not included in the project, Visual Studio will not automatically detect changes in the files
+  - To ensure plugins are updated when testing the app, click **Rebuild Solution** before clicking **Start**
+- **Error: The command (...) exited with code 1**
+  - If the post-build event fails, open the **Output** tab and look for the cause
+  - Determine if there was an IO error while copying files or modifying folders, or whether the final .ps1 script failed (`Encountered an error while running PostBuild.ps1 on line xyz`)
+  - Some files are checked for invalid characters:
+    - `Resources/Plugins/emoji-keyboard/emoji-ordering.txt` line endings must be LF (line feed); any CR (carriage return) in the file will cause a failed build, and you will need to ensure correct line endings in your text editor
+
+### Installers
+
+TweetDuck uses **Inno Setup** to automate the creation of installers. 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 despite the name, this will only package the files, you still need to run the [build](#build) 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)
+* **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
+
+Note: There is a small chance you will see a resource error when running `RUN BUILD.bat`. If that happens, close the console window (which will terminate all Inno Setup processes and leave corrupted installer files in the output folder), and run it again.
+
+### Code Notes
+
+There are many references to the official TweetDuck website and this repository in the code and installers, so if you plan to release your own version, make sure to search for `tweetduck.chylex.com` and `github.com` in the whole repository and replace them appropriately.
