+## [Project site (consider giving it a star!)](https://github.com/spessasus/SpessaSynth)
 
-[Documentation](https://github.com/spessasus/SpessaSynth/wiki/Usage-As-Library)
+## [Complete documentation](https://github.com/spessasus/SpessaSynth/wiki/Usage-As-Library)
 
-Make sure to add the worklet module `synthetizer/worklet_processor.min.js`
+## Current Features
+### Easy Integration
+- **Modular design:** Easy integration into other projects (load what you need)
+- **[Detailed documentation:](https://github.com/spessasus/SpessaSynth/wiki/Home)** With [examples!](https://github.com/spessasus/SpessaSynth/wiki/Usage-As-Library#examples)
+- **Easy to Use:** basic setup is just [two lines of code!](https://github.com/spessasus/SpessaSynth/wiki/Usage-As-Library#minimal-setup)
+- **No dependencies:** _batteries included!_
 
+### Powerful SoundFont Synthesizer
+- Suitable for both **real-time** and **offline** synthesis
+- **Excellent SoundFont support:**
+- - **Generator Support**
+- - **Modulator Support:** _First (to my knowledge) JavaScript SoundFont synth with that feature!_
+- - **SoundFont3 Support:** Play compressed SoundFonts!
+- - **Can load very large SoundFonts:** up to 4GB! _Note: Only Firefox handles this well; Chromium has a hard-coded memory limit_
+- **Reverb and chorus support:** [customizable!](https://github.com/spessasus/SpessaSynth/wiki/Synthetizer-Class#effects-configuration-object)
+- **Export audio files** using [OfflineAudioContext](https://developer.mozilla.org/en-US/docs/Web/API/OfflineAudioContext)
+- **[Custom modulators for additional controllers](https://github.com/spessasus/SpessaSynth/wiki/Modulator-Class#default-modulators):** Why not?
+- **Written using AudioWorklets:** runs in a separate thread for maximum performance, works perfectly in Firefox and Chrome!
+- **Unlimited channel count:** Your CPU is the limit!
+- **Various MIDI Standards Support:**
+- - **MIDI Controller Support:** Default supported controllers [here](https://github.com/spessasus/SpessaSynth/wiki/MIDI-Implementation#supported-controllers)
+- - [Full **RPN** and limited **NRPN** support](https://github.com/spessasus/SpessaSynth/wiki/MIDI-Implementation#supported-registered-parameters)
+- - Supports some [**Roland GS** and **Yamaha XG** system exclusives](https://github.com/spessasus/SpessaSynth/wiki/MIDI-Implementation#supported-system-exclusives)
+- **High-performance mode:** Play Rush E! _note: may kill your browser ;)_
+- **Written in pure JavaScript using the WebAudio API:** Supported by all modern browsers!
+
+### Built-in Powerful and Fast Sequencer
+- **Supports MIDI formats 0, 1, and 2:** _note: format 2 support is experimental as it's very, very rare_
+- **[Multi-Port MIDI](https://github.com/spessasus/SpessaSynth/wiki/About-Multi-Port) support:** More than 16 channels!
+- **Smart preloading:** Only preloads the samples used in the MIDI file for smooth playback (down to key and velocity!)
+- **Lyrics support:** Add karaoke to your program!
+- **Raw lyrics available:** Decode in any encoding! (Kanji? No problem!)
+
+### Read and Write SoundFont and MIDI Files with Ease
+#### Read and write MIDI files
+- **Smart name detection:** Handles incorrectly formatted and non-standard track names
+- **Port detection during load time:** Manage ports and channels easily!
+- **Used channels on track:** Quickly determine which channels are used
+- **Key range detection:** Detect the key range of the MIDI
+- **Easy MIDI editing:** Use [helper functions](https://github.com/spessasus/SpessaSynth/wiki/Writing-MIDI-Files#modifymidi) to modify the song to your needs!
+- **Loop detection:** Automatically detects loops in MIDIs (e.g., from _Touhou Project_)
+- **First note detection:** Skip unnecessary silence at the start by jumping to the first note!
+- **Easy saving:** Save with just [one function!](https://github.com/spessasus/SpessaSynth/wiki/Writing-MIDI-Files#writemidifile)
+#### Read and write [RMID files with embedded SF2 soundfonts](https://github.com/spessasus/SpessaSynth/wiki/About-RMIDI)
+- **Compression and trimming support:** Reduce a MIDI file with a 1GB soundfont to **as small as 5MB**!
+- **Easy saving:** [As simple as saving a MIDI file!](https://github.com/spessasus/SpessaSynth/wiki/Writing-MIDI-Files#writermidi)
+#### Read and write SoundFont2 files
+- **Smart trimming:** Trim the SoundFont to only include samples used in the MIDI (down to key and velocity!)
+- **sf3 conversion:** Compress SoundFont2 files to SoundFont3!
+- **Easy saving:** Also just [one function!](https://github.com/spessasus/SpessaSynth/wiki/SoundFont2-Class#write)
+#### Read and write SoundFont3 files
+- Same features as SoundFont2 but with now with **Ogg Vorbis compression!**
+- **Variable compression quality:** You choose between file size and quality!
+- **Compression preserving:** Avoid decompressing and recompressing uncompressed samples for minimal quality loss!
