+# compare-locales
+Lint Mozilla localizations
+
+Finds
+* missing strings
+* obsolete strings
+* errors on runtime errors without false positives
+* warns on possible runtime errors
+
+It also includes `l10n-merge` functionality, which pads localizations with
+missing English strings, and replaces entities with errors with English.
+
+If you want to check your original code for errors like duplicated messages,
+use `moz-l10n-lint`, which is also part of this package. You can also use
+this to check for conflicts between your strings and those already exposed
+to l10n.
+
+# Configuration
+
+You configure `compare-locales` (and `moz-l10n-lint`) through a
+[project configuration](https://moz-l10n-config.readthedocs.io/en/latest/fileformat.html)
+file, `l10n.toml`.
+
+# Examples
+
+To check all locales in a project use
+
+```bash
+compare-locales l10n.toml .
+```
+
+To check Firefox against a local check-out of l10n-central, use
+
+```bash
+compare-locales browser/locales/l10n.toml ../l10n-central
+```
+
+If you just want to check particular locales, specify them as additional
+commandline parameters.
+
+To lint your local work, use
+
+```bash
+moz-l10n-lint l10n.toml
+```
+
+To check for conflicts against already existing strings:
+
+```bash
+moz-l10n-lint --reference-project ../android-l10n/mozilla-mobile/fenix l10n.toml
+moz-l10n-lint --l10n-reference ../gecko-strings browser/locales/l10n.toml
+```
+
+to check for a monolithic project like Fenix or a gecko project like Firefox,
+resp.
