+    Classes that don't support this are serialized and stored with the

+    
+    The mimetype is used for serialized objects, and tells the

+    extensible. For a given mimetype the value must be set accordingly:
+

-# SRT subtitles to 3D subtitles
+# SRT to 3D Subtitles
-## The problem
-I wanted watch a movie with subtitle, like I always do, but the subtitles for the movie I have was traditional .srt while the movie I was watching was a 3D movie which was **H**alf **S**ide **B**y **S**ide (HSBS). The subtitles in question were centered which was very disorienting to read while watching the movie. The solution? Write my own program to convert it for me.
 
-## Convert
+Convert standard `.srt` subtitles into `.ass` format, offset so they display correctly in 3D video playback.
-Currently just a command line program to convert a .srt subtitle file to an .ass subtitle file while making it compatible with the HSBS format. Either drag the SRT file on the .exe to convert the .srt file or run the command `SRTto3D.exe [insert your file name here]` and the program will convert it. Word of warning, the program will strip off any positional data off the srt. It will also likely fail with .srt file that contain a positional information. 
+
+## The Problem
+
+When watching 3D movies (Side-by-Side, Over-Under, Anaglyph), centered subtitles get split between the left and right eye views, making them disorienting to read. This tool converts standard `.srt` subtitles into a 3D-compatible `.ass` format that keeps each eye's subtitles in the correct position.
 
 ## Features
-_Basically nothing right now_
-- [x] Convert a .srt to an .ass/.ssa
-  - [x] For HSBS media 
-  - [ ] For **S**ide **B**y **S**ide (SBS) media 
-  - [ ] For **O**ver **U**nder (OU) media
-  - [ ] For Anaglyph 3D media (red and green media)
-  - [ ] For traditionally media (pancake mode).
-    - _I suggest to just use ffmpeg for this use case_
-- [x] Convert formatting of .srt subtitles to transfer to the converted version
-  - [ ] Convert positional data of .srt subtitles
-- [ ] Add changes which allows custom:
-  - [ ] Font
-  - [ ] Color
-  - [ ] Position
-  - [ ] Margins
-  - [ ] Encoding
-- [ ] Add a proper GUI
-- [ ] Any form of error handling or unit testing
 
+- **SBS (Side-by-Side)** — subtitles split left/right for each eye
+- **OU (Over-Under)** — subtitles split top/bottom for each eye
+- **Anaglyph (Red/Green)** — subtitles offset with red/green color channels
+- **CLI** — full command-line interface with configurable options
+- **GUI** — lightweight Windows interface for easier mode selection
+- **Formatting support** — converts HTML tags (`<b>`, `<i>`, `<u>`, `<font color>`) to ASS format codes
+- **Resolution scaling** — adjusts subtitle positioning based on target resolution
+
+## Usage
+
+The application runs in two modes — **GUI** (no arguments) and **CLI** (with arguments).
+
+### GUI
+
+1. Launch `ConvertSRTto3DASS.exe` (or the Linux/macOS binary)
+2. Select your `.srt` input file
+3. Choose your 3D mode (SBS, OU, or Anaglyph)
+4. Adjust settings as needed
+5. Click **Convert**
+
+> **Note:** The GUI is experimental. Feedback and bug reports are welcome!
+
+### Command Line
+
+The CLI runs on **Windows, Linux, and macOS**.
+
+#### Drag and drop:
+1. Drag and drop an `.srt` file onto `ConvertSRTto3DASS`
+   - Uses default settings (SBS mode, 1280x720)
+2. The resulting `.ass` file will be saved in the same directory as the `.srt`
+
+#### Command line:
+ ```
+
+ ConvertSRTto3DASS.exe input.srt [options]
+
+ ```
+
+##### Available options:
+ ```
+
+--mode sbs|ou|rg              3D mode (default: sbs)
+--resx <number>               Output width
+--resy <number>               Output height
+--baseresx <number>           Scaling reference width (default: 1280)
+--baseresy <number>           Scaling reference height (default: 720)
+--fontsize <number>           Font size (default: 16)
+--offsetx <number>            RG eye separation
+--bottomoffset <number>       RG bottom offset
+--sbssidemargin <number>      SBS side margin
+--outopmargin <number>        OU top subtitle margin
+--verticalmargin <number>     General vertical margin
+--output <path>               Output file path
+--help, -h, /?                Show help
+
+ ```
+ 
+##### Examples:
+ ```
+
+ ConvertSRTto3DASS.exe movie.srt --mode sbs
+ ConvertSRTto3DASS.exe movie.srt --mode ou --resx 1920 --resy 1080
+ ConvertSRTto3DASS.exe movie.srt --mode rg --offsetx 6 --bottomoffset 24
+
+ ```
 
 ## Known Issues
-For some reason that I have yet to understand, Plex Transcoder doesn't not like the converted subtitles (it has a weird issue) but it works perfectly in VLC
 
-## Warning
+- Subtitle positional data from `.srt` files is stripped during conversion.
-The code is a complete and utter mess with very little comments in it. This was meant to be a private project and I haven't had the chance to clean it up yet.
+
+## Requirements
+
+- **.NET 8 SDK** — required to build
+- **Windows** — the GUI runs on Windows
+- **Linux/macOS** — the CLI runs cross-platform
+
+## Building
+
+```bash
+# Build all projects
+dotnet build
+
+# Publish CLI (self-contained)
+## Linux x64
+dotnet publish ConvertSRTto3DASS.Cli -c Release -r linux-x64 --self-contained true -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true
+## OSX x64
+dotnet publish ConvertSRTto3DASS.Cli -c Release -r osx-x64 --self-contained true -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true
+## OSX arm64
+dotnet publish ConvertSRTto3DASS.Cli -c Release -r osx-arm64 --self-contained false -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true
+## Windows x64
+dotnet publish ConvertSRTto3DASS.Cli -c Release -r win-x64 --self-contained true -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true
+
+# Publish GUI (Windows x64 only, self-contained)
+dotnet publish ConvertSRTto3DASS.Gui -c Release -r win-x64 --self-contained true -p:PublishSingleFile=true -p:IncludeNativeLibrariesForSelfExtract=true
+ ```
+
+ _Each publish produces a single .exe with no .dll sidecars._
