+Translating:
+------------
+
+The scrip `update-translations.sh` can be used to update the language template and translation files from source.
+It will generate the file `locale/mail-hosting.pot` which you can then use as basis to create a new language file in `YOUR_LANG_CODE/LC_MESSAGES/mail-hosting.po` and edit it with a translation program, such as [Poedit](https://poedit.net/).
+Once you are done, you can open a pull request, or [email me](mailto:daniel@danwin1210.de), to include the translation.

-<h2>What you will get</h2>
-<p>You get a free anonymous E-Mail address and an XMPP/Jabber account using the same details. Your Jabber ID is user@danwin1210.de and can be connected to directly from clearnet or via TOR hidden service (danielas3rtn54uwmofdo3x2bsdifr47huasnmbgqzfrec5ubupvtpid.onion).</p>
-<p>You will have 50MB of disk space available for your mails. If you desperately need more space, just <a href="/contact.php">contact me</a>. Your E-Mail address will be user@danwin1210.de</p>
-<p>For privacy, please use PGP mail encryption, if you can. This prevents others from reading your mails (including me and/or LEA). GnuPGs official home: <a href="https://gnupg.org">https://gnupg.org</a> Windows GUI: <a href="https://gpg4usb.org">https://gpg4usb.org</a></p>
-<h2>E-Mail Setup</h2>

-POP3: danwin1210.de Port 995 (SSL/TLS) or 110 (StartTLS)<br>
-Authentication: PLAIN, LOGIN</p>
-<p>You can also connect on the same ports via the tor onion address danielas3rtn54uwmofdo3x2bsdifr47huasnmbgqzfrec5ubupvtpid.onion, but you will have to accept an SSL certificate only valid for the clearnet domain.</p>
