I made a GUI for the java version, so it should be easier to use now~!
To make your own index.csv, format it like this:
These will get generated into aliases like this:
[- a][a ny][ny yeo][yeo ng][ng -]
[- i][ i like][like big][big butts][butts -]
As for replace.csv, it's like this.
original alias,new alias
So you could make a replace.csv like this
I made an index and replace for japanese, so you can look at those for an example.
