+Uploading to Transifex
+^^^^^^^^^^^^^^^^^^^^^^
+
+There's several different ways to upload a finished (or semi-finished)
+translation for a new language to Transifex. The easiest way is to browse to
+the http://www.transifex.net/projects/p/calcurse/teams/[Translation Teams] page
+and request the addition of a new team.
+
+As soon as we accepted your request, you will be able to upload your *po* file
+on the
+http://www.transifex.net/projects/p/calcurse/resource/calcurse-pot/[calcurse
+resource page] by clicking the *Add translation* button at the bottom.
+
+Using transifex-client
+^^^^^^^^^^^^^^^^^^^^^^
+
+You can also use a command line client to submit translations instead of having
+to use the web interface every time you want to submit an updated version. If
+you have a recent version of setuptools installed, you can get the CLI client
+by issuing the following command:
+
+----
+$ easy_install -U transifex-client
+----
+
+Alternatively, you can get the source code of transifex-client at
+http://pypi.python.org/pypi/transifex-client.
+
+After you downloaded and installed the client, run the following commands to
+checkout the translation resources of *calcurse*:
+
+----
+$ tx init --host=http://www.transifex.net
+$ tx set --auto-remote http://www.transifex.net/projects/p/calcurse
+$ tx pull -r calcurse.calcurse-pot -a
+----
+
+To submit changes back to the server, you can use `tx push` (check `tx help
+push` for available options). For more details, read up on transifex-client
+usage at the http://help.transifex.net/user-guide/client/[The Transifex
+Command-line Client v0.4] section of the http://help.transifex.net/[Transifex
+documentation].
+
+[[transifex_webui]]
+Using the Transifex web UI
+^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+As an alternative to editing *po* files, there is a web-based interface that
+can be used to create and update translations. After having signed up and
+created a new translation team (see <<transifex_uploading,Uploading to
+Transifex>> on how to do that), click the *Add translation* button at the
+bottom on the
+http://www.transifex.net/projects/p/calcurse/resource/calcurse-pot/[calcurse
+resource page], select the language you'd like to translate and choose
+*Translate Online*.
