This is a layout for easily writing accented characters commonly used in languages written with the Latin alphabet. For example, here's some common characters:

• á = ;as
• à = ;af
• ã = ;ax
• ả = ;ar
• ạ = ;aj
• ă = ;aw
• â = ;aa
• ê = ;ee
• ê = ;ee
• ü = ;uv
• ư = ;uw
• ű = ;u;
• ç = ;c
• ñ = ;n
• ấ = ;jaas
• č = ;jc

Non-accented characters can be typed as usual. To type ; itself, use ;;

First ensure you have plum installed. For macOS this would be:

cd ~/Library/Rime
wget https://git.io/rime-install

Then install gkovacs/rime-international using plum:

bash rime-install gkovacs/rime-international

Finally edit default.custom.yaml and add international to the schema list:

patch:
  schema_list:
    - schema: international

Now reload RIME and it should appear under your layouts.
