+`tja2fumen` is a tool for Taiko no Tatsujin that allows you to convert TJA charts (`.tja`) to fumen charts (`.bin`).
 
-This project attempts to replace/complement the existing closed-source [tja2bin.exe](https://github.com/Fluto/TakoTako/blob/c269bcab60530877a16c2a473c84796b94d0a5ce/README.md?plain=1#L181) converter packaged alongside TakoTako. 
+### Goals
 
-## Goals
-
-- Act as a drop-in replacement for `tja2bin.exe` in TakoTako.
-- Fix https://github.com/Fluto/TakoTako/issues/16. (The original `tjabin.exe` doesn't properly handle `#BPMCHANGE` commands.)
-- Better handle commands that `tjabin.exe` fails for (`#SECTION`, `#NEXTSONG`, `#LYRIC`, etc.)
 - Provide open source code to act as a reference for parsing and writing both the TJA and Fumen file formats.
-- Stick to the Python stdlib, i.e. no external dependencies if possible.
+- Fix the existing issues with `tja2bin.exe`:
+  - Desync due to `#BPMCHANGE` commands. (https://github.com/Fluto/TakoTako/issues/16)
+  - Crashes due to `#SECTION`, `#NEXTSONG`, `#LYRIC`, etc. commands.
 
-## Usage
+# Usage
 
-### Option 1: Standalone Python installation
+tja2fumen is included as part of several existing projects. So, you may be using tja2fumen already!
 
-If you're familiar with Python, you can install `tja2fumen` by running:
+- **XB1/TDMX**: [TakoTako](https://github.com/fluto/takotako) converts both chart and audio files for XB1/TDMX.
+- **Nijiro**: [TaikoSoundEditor](https://github.com/NotImplementedLife/TaikoSoundEditor) converts both chart and audio files for NIjiro.
 
-```
+## → Adding `tja2fumen.exe` to older TakoTako versions (3.2.0 and below)
-pip install tja2fumen
-```
-
-Then, you can convert a TJA file by running:
-
-```
-tja2fumen file.tja
-```
-
-### Option 2: Using with TakoTako
 
 > **Note**: Before adding `tja2fumen` to TakoTako, you may want to back up the original `tja2bin.exe` file, to make sure you can switch back to the old converter if necessary. The easiest way to do this is by renaming the existing file to `tja2bin.exe.bak`.
 
-To use this converter with TakoTako, head to the [Releases](https://github.com/vivaria/tja2fumen/releases) page, and download the `tja2fumen.exe` file attached to the release. Then, rename `tja2fumen.exe` to `tja2bin.exe`, and place the file in the TakoTako plugin folder.

+## → Using `tja2fumen` directly
+
+If you'd like to build a project on top of `tja2fumen`, you have several options:
+
+### 1. Using the executable file (`tja2fumen.exe`)
+
+Head to the [Releases](https://github.com/vivaria/tja2fumen/releases) page, and download the `tja2fumen.exe` file attached to the release.
+
+Then, you can convert a TJA file on the command line by running:
+
+```
+tja2fumen.exe file.tja
+```
+
+### 2. Using the `tja2fumen` Python package
+
+If you're familiar with Python, you can install `tja2fumen` by running:
+
+```
+pip install tja2fumen
+```
+
+Then, you can convert a TJA file on the command line by running:
+
+```
+tja2fumen file.tja
+```
+
+Or, you can import the `main` function in your Python code, and convert TJA files this way instead:
+
+```python
+from tja2fumen import main
+main(argv=["file.tja"])
+```
+
+# Reporting bugs
+
+If you've found a .TJA file that `tja2fumen` converts incorrectly, please [open a new issue](https://github.com/vivaria/tja2fumen/issues/new) on the tja2fumen repo. 
+
+It is especially important that you attach the song files to the issue. You can do this by adding the song files to a `.zip` (Select files -> Right click -> "Send to" -> "Compressed (zipped) folder"), and then uploading the `.zip` to the issue. This greatly helps me to reproduce and fix any issues.
