+Updating the translations
+-------------------------
+
+  1. Check if there are any new languages with progress more than 50% on [transifex](https://www.transifex.com/projects/p/foreman/resource/hammer-cli-csv/). If so, do the following for each of the new languages:
+
+  ```
+    mkdir locale/<lang>
+    cp locale/hammer_cli_csv.pot locale/<lang>/hammer_cli_csv.po
+  ```
+  2. Make sure you have `transifex-client` installed
+
+  3. Update the translations. From GIT repo root directory run:
+
+  ```
+    make -C locale tx-update
+  ```
+
+  It will download translations from transifex, generates `mo` files, updates strings in `pot` file and wraps all the changes in a new commit. Transifex automatically updates its strings when the commit is pushed to Github.
