 Translation jobs
 ----------------
 
-We have two types of Jenkins jobs for translations: syncing Zanata with the
-latest repositories and pushing translations into the repositories.
-The first job is for Zanata-side updates. It enables Zanata to have up-to-date
-texts to be translated by comparing OpenStack project repositories and Zanata.
-On the other hand, the second job is aimed to reflect changes related to
-translations. For example, if you contribute translations in Zanata, the
-translation results need to be pushed to the corresponding repositories.

+The first job is for Zanata-side updates. Up-to-date source strings to be

+and Zanata. If source texts in OpenStack project repositories are changed,
+then change sets are pushed into Zanata so translaters deal with up-to-date
+source strings.
+On the other hand, the second job is aimed to reflect changes in translated
+strings in Zanata (after translators do translation activities) into
