+### Transifex Command
+
+The `translations-merge-update.sh` script contains the following transifex
+client command:
+```shell
+tx -q pull -a --mode developer
+```
+- **`-q`**
+  - *`-q`, `--quiet`: don't print status messages to stdout* (`tx --help`,
+    formatting updated)
+- **`pull`**
+    - *The `tx pull` command lets you download translation files from Transifex
+      for use.*
+- **`-a`**
+  - *`-a` or `--all`: Fetch all translation files from server, even ones which
+    don’t exist already locally. If this option isn’t included, only the files
+    that exist locally will be updated. If your pull command is skipping files,
+    try to add this switch in combination with -f.*
+- **`--mode developer`**
+    - *`developer`: The files downloaded will be compatible with the i18n
+      support of the development framework you’re using. This is the default
+      mode when you run tx pull. Use this mode when you intend to use the file
+      e.g. in production. This mode auto-fills empty translations with the
+      source language text for most of the file formats we support, which is
+      critical in the case of file formats that require all translations to be
+      non-empty.*
