+Zanata is a web-based system for managing localisation projects.
+For kexec-tools firstboot module, I created a zanata project with name of
+"kexec-tools": https://translate.zanata.org/zanata/project/view/kexec-tools
+
+There's several clients available for zanata translation management, such as
+python client and Maven client. It's suggested to use maven client for latest
+zanata issues
+
+Firstly you need install mvn rpms, just do below for fedora 16 and beyond:
+yum install maven
+
+create zanata.ini in your home dir:
+>~/.config/zanata.ini
+There should be something need to change like below:
+translate_zanata_org.url=https://translate.zanata.org/zanata/
+translate_zanata_org.username=
+translate_zanata_org.key=
+
+Change username to your zanata username
+Change the key to the "API key" of zanata which can be generate from
+zanata web page.
+ Open user profile page of zanata.org, click "Generate API Key" to create it.
+
+zanata is a plugin of maven, to activate it, you need do below configurations:
+1. cd kexec-tools/po, (assume kexec-tools is the git repo)
+2. add a pom.xml like below: (note: version 2.0.0 is better than 1.7.5
+for performance improvement)
+<project>
+...
+  <build>
+    <plugins>
+      <plugin>
+        <groupId>org.zanata</groupId>
+        <artifactId>zanata-maven-plugin</artifactId>
+        <version>1.7.5</version>
+      </plugin>
+    </plugins>
+  </build>
+...
+</project>
+3. add zanata.xml for your project with content like below:
+<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
+<config xmlns="http://zanata.org/namespace/config/">
+  <url>https://translate.zanata.org/zanata/</url>
+  <project>kexec-tools</project>
+  <project-version>F18</project-version>
+  <project-type>gettext</project-type>
+
+  <locales>
+    <locale>ar</locale>
+...
+</config>
+
+You can get mostly-complete zanata.xml from the project version page on zanata
+Things need to be modified is:
+a) project-type, please use gettext
+b) for locales which are diffrent between local name and zanata server name,
+   for example for kexec-tools we have bn_IN but zanata server accept bn-IN,
+   so we need to add below line:
+   <locale map-from="bn_IN">bn-IN</locale>
+
+The first running of "mvn zanata:help" will download and activate the new
+version of zanata plugin for you.
+
+I use below command to upload both pot file and translated po files:
+mvn zanata:push -Dzanata.pushType=both
+If you only need to upload po files, you can use:
+mvn zanata:push -Dzanata.pushType=trans
+
+You can use mvn zanata:help to lookup the detail help content of param names
+
+The other thing to be careful is specifying the correct source and
+translation directories. 
+They are relative path. You can also put the pom.xml and zanata.xml under toplevel directory and run:
+mvn zanata:push -Dzanata.pushType=both -Dzanata.srcDir=po -Dzanata.transDir=po
