 This is a zero-dependency, super small, IP address to 2-letter [country code](https://en.wikipedia.org/wiki/ISO_3166-1_alpha-2) lookup library. There are already several libraries available, but none met our requirements for binary size and speed.

+## Binary data
+
+To make this library easy to consume, we're using [btoj](https://github.com/statsig-io/btoj) to transform the necessary binary data into a js module that can be imported like any other module. You won't need to list `ip3country` as an external in your build process.
+
+We're currently using brotli compression via [NodeJS's `zlib` library](https://nodejs.org/api/zlib.html#zlib_zlib_brotlicompresssync_buffer_options), which won't work in Browser environments. If you want `ip3country` on a browser, check version `3.0.0` (and feel free to publish `ip3country-browser`).

 ## Name
 
 All variants of "ip2country" were already taken in npm, so we decided to step it up.
