+# Internationalization
+
+We want the official Bluesky app to be supported in as many languages as possible. If you want to help us translate the app, please reach out to us at info@blueskyweb.xyz
+
+## Tools
+We are using Lingui to manage translations. You can find the documentation [here](https://lingui.dev/).
+
+### Adding new strings
+When adding a new string, do it as follows:
+```jsx
+// Before
+import { Text } from "react-native";
+<Text> Hello World </Text>
+```
+
+```jsx
+// After
+import { Text } from "react-native";
+import { Trans } from "@lingui/macro";
+<Text><Trans> Hello World </Trans></Text>
+```
+
+We can then run `yarn intl:extract` to update the catalog in `src/locale/locales/{locale}/messages.po`. This will add the new string to the catalog.
+We can then run `yarn intl:compile` to update the translation files in `src/locale/locales/{locale}/messages.js`. This will add the new string to the translation files. 
+The configuration for translations is defined in `lingui.config.js`
