-### How it works
+# SmallStrings | Reduce localized .strings file sizes by 80%
+#### Maintained by [Emerge Tools](https://emergetools.com?utm_source=smallstrings) 
 
-The library consists of a build-time minification step, and an iOS library:
-- The minification tool converts the .strings files (of the form App.app/\*.lproj/Localizable.strings only) into a minified form. First, this tool eliminates key duplication by following the strategy from https://eisel.me/localization. This reduces the size by roughly 50%. Then, it keeps all these small files in a compressed form on disk, using LZFSE, reducing the size further. It also replaces the original language.lproj/Localizable.strings with placeholders that have one key-value pair each. This shows Apple that the same languages are still supported, so that it can pick the correct one based on the user's settings.
-- An iOS library that replaces `NSLocalizedString` with a new version, `SSTStringForKey` that fetches values for keys from this minified format.
+### How does it work
+
+- Convert .strings files (of the form App.app/\*.lproj/Localizable.strings only) into a minified form
+- Eliminate key duplication ([read more about the strategy](https://eisel.me/localization)), this typically reduces the size by about 50%
+- Keep small files in a compressed form on disk, using LZFSE, to reduce the size further
+- Replace the original language.lproj/Localizable.strings with placeholders that have one key-value pair each. This shows Apple that the same languages are still supported, so that it can pick the correct one based on the user's settings.
+- Use the iOS library that replaces `NSLocalizedString` with a new version, `SSTStringForKey` that fetches values for keys from this minified format.
