+## How to add new language translation to Remark42
+
+Translation files are stored in [/frontend/app/locales](https://github.com/umputun/remark42/tree/master/frontend/app/locales)
+directory with `.json` extension and content like following:
+
+```json
+{
+  "anonymousLoginForm.length-limit": "Username must be at least 3 characters long",
+  "anonymousLoginForm.log-in": "Log in",
+  "anonymousLoginForm.symbol-limit": "Username must start from the letter and contain only latin letters, numbers, underscores, and spaces",
+<...>
+}
+```
+
+### How to add a new translation
+
+We truly appreciate people spending time contributing their translations to remark42. Please go through the steps
+below in order to have your translation start being available to all remark42 users and included in the next release.
+
+1. create a fork of [umputun/remark42](https://github.com/umputun/remark42) repo, and if you already have one please
+pull the latest changes from the upstream master branch. It could be done like that:
+   ```shell
+   git remote add upstream https://github.com/umputun/remark42.git
+   git fetch upstream
+   git rebase upstream/master
+   git push
+   ```
+1. add new locale with [two-letter code](https://en.wikipedia.org/wiki/List_of_ISO_639-1_codes)
+of the language you want to make the translation into to list in
+[frontend/tasks/supportedLocales.json](https://github.com/umputun/remark42/blob/master/frontend/tasks/supportedLocales.json)
+1. run `npm run generate-langs` in `frontend` folder
+1. translate all values in the newly created json file in
+[frontend/app/locales/](https://github.com/umputun/remark42/blob/master/frontend/app/locales/)
+1. commit all changes above in your fork
+1. test your changes in the interface:
+    1. uncomment `locale: "ru"` line in [frontend/index.ejs](https://github.com/umputun/remark42/blob/master/frontend/index.ejs#L133)
+    and replace `ru` with your translation language code
+    1. [run remark42 in Docker](https://github.com/umputun/remark42#development) by issuing following commands
+    from the root directory of your remark42 fork:
+
+        ```shell
+        docker-compose -f compose-dev-frontend.yml build
+        docker-compose -f compose-dev-frontend.yml up
+        ```
+    1. open [http://127.0.0.1:8080](http://127.0.0.1:8080), log in, make a comment, make a reply to a comment,
+    and make sure that your translation looks as you expect it to look
+    1. make a screenshot from [http://127.0.0.1:8080](http://127.0.0.1:8080) with your translation in place
+1. after all previous steps are done, create a [Pull Request](https://github.com/umputun/remark42/pulls) to umputun/remark42
+repo with your changes, attaching a screenshot or two from your local test instance to it
