 # introduction
 
-Furnace is a tool which allows you to create music using emulated sound chips from the 8/16-bit era.
-For a full list of soundchips that Furnace supports, please see [this list](https://github.com/tildearrow/furnace/tree/master/papers/doc/7-systems).
+Furnace is a tool which allows you to create music using sound chips ("chiptune"), most from the 8/16-bit era.
 
-It has a music tracker interface. think of a piano roll, or a table that scrolls up and plays the notes.
+it has a large selection of features and sound chips. from the NES, SNES and Genesis to ES5506, VIC-20 or even Arcade, Furnace has most likely covered your target with many presets to choose from.
 
-Another core feature of Furnace is its windowing system, similar to that of GEMS or Deflemask, but with a few more features.
+every chip is emulated using many emulation cores, therefore the sound that Furnace produces is authentic to that of real hardware.
 
-## Interface
-
-Furnace is built to have a user-friendly interface that is intentionally made so that it is quick and easy to get around when working in Furnace.
-However, we understand that the interface may not be the easiest to learn, depending on how you learn, so there is documentation on it as well.
-
-See [2-interface](https://github.com/tildearrow/furnace/tree/master/papers/doc/2-interface) and [3-pattern](https://github.com/tildearrow/furnace/tree/master/papers/doc/3-pattern) to view said documentation.

-## Hexadecimal
+## hexadecimal
 
 Furnace uses hexadecimal (abbreviated as "hex") numbers frequently. see [this guide](hex.md) for a crash course.
 
-## Sound generation
+## interface
 
-Furnace generates sound from 3 different main types of sound sources.
- - Instruments are the most standard and most used type of sound source in Furnace.
-The instrument format is how you can specify parameters and macros for certain channels on certain soundchips, as well as binding samples and wavetables to a format that you can sequence on the note grid.
-See [4-instrument](https://github.com/tildearrow/furnace/tree/master/papers/doc/4-instrument) for more details.
- - Wavetables are the way that you create custom waveform shapes for the HuC6280, Seta X1-010, WonderSwan, any PCM chip with wavetable synthesizer support, etc.
-Wavetables only work in the sequencer if you bind them to an instrument. See [4-instrument](https://github.com/tildearrow/furnace/tree/master/papers/doc/4-instrument) and [5-wave](https://github.com/tildearrow/furnace/tree/master/papers/doc/5-wave) for more details.
- - Samples are how you play back raw audio streams (samples) on certain channels, on certain soundchips, and in some cases, in certain modes.
-To sequence a sample, you do not need to assign it to an instrument, however, to resample samples (change the speed of a sample), you need to bind it to a Sample instrument.
-See [6-sample](https://github.com/tildearrow/furnace/tree/master/papers/doc/6-sample) and [4-instrument](https://github.com/tildearrow/furnace/tree/master/papers/doc/4-instrument) for more details.
+Furnace uses a music tracker interface. think of a table with music notes written on it. then that table scrolls up and plays the notes.
 
+due to its nature of being feature-packed, it may be technical and somewhat difficult to get around. therefore we added a basic mode, which hides several advanced features.
+
+it also has a flexible windowing system which you may move around and organize.
+
+see [2-interface](../2-interface/README.md) and [3-pattern](../3-pattern/README.md) for more information.
