+## Adding new language support
+
+If you want to add support for a new language, you can do so by following these steps:
+
+1. Fork the repository.
+2. Create a new file in `data/books` with the name of the language (e.g. `data/books/pl.json`) with books names.
+3. Import json file to `src/Books.ts` as shown in the example:
+
+```ts
+import _pl from "../data/books/pl.json";
+```
+
+```ts
+const pl = _pl as {
+	[key: string]: string[];
+};
+```
+
+```ts
+Object.keys(books).forEach((b) => {
+	books[b].push(
+		// ...
+		...pl[b]
+		// ...
+	);
+});
+```
+
+(See the other languages for examples.)
+
+4. Add your name to the list above in this file (`Languages.md`).
+5. Create a PR with the changes. (I will review it and merge it.)
