Step 1: download the font you like. Make sure you have the rights to use it in your game. I used this font, which is available under the open font license.
Step 2: go to Transfonter
Step 3: upload the font using the ‘Add fonts’ button. The best formats to use are TTF and WOFF/WOFF2 since they are supporsted by all browsers.
