-Init Project
-^^^^^^^^^^^^
+After installing ``transifex`` using pip, run the following command to initialize the project.
 
 .. code:: shell
 
     tx init # Transifex instance: https://www.transifex.com/asciimoo/searx/
 
+
+After ``$HOME/.transifexrc`` is created, get a Transifex API key and insert it into the configuration file.
+
+Create a configuration file for ``tx`` named ``$HOME/.tx/config``.
+
+.. code:: shell
+
+    [main]
+    host = https://www.transifex.com
+    [searx.messagespo]
+    file_filter = searx/translations/<lang>/LC_MESSAGES/messages.po
+    source_file = messages.pot
+    source_lang = en
+    type = PO
+
+
+Then run ``tx set``:
+
+.. code:: shell
+
     tx set --auto-local -r searx.messagespo 'searx/translations/<lang>/LC_MESSAGES/messages.po' \
     --source-lang en --type PO --source-file messages.pot --execute
