+this file must be updated to reflect those changes. This can be accomplished
+by running `lupdate` (included in the Qt SDK). Also, a custom script is used
+to extract strings from the non-Qt parts:
+
+    python share/qt/extract_strings_qt.py
+    lupdate bitcoin-qt.pro -no-obsolete -locations none -ts src/qt/locale/bitcoin_en.ts
+    
+##### Handling of plurals in the source file
+
+When new plurals are added to the source file, it's important to do the following steps:
 
-An updated source file should be merged to github and transifex will pick it
-up from there. Afterwards the new strings show up as "Remaining" in transifex
-and can be translated.
+1. Open bitcoin_en.ts in Qt Linguist (also included in the Qt SDK)
+2. Search for `%n`, which will take you to the parts in the translation that use plurals
+3. Look for empty `English Translation (Singular)` and `English Translation (Plural)` fields
+4. Add the appropriate strings for the singular and plural form of the base string
+5. Mark the item as done (via the green arrow symbol in the toolbar)
+6. Repeat from step 2. until all singular and plural forms are in the source file
+7. Save the source file
+
+##### Creating the pull-request
 
-Syncing with transifex
+An updated source file should be merged to github and Transifex will pick it
+up from there (can take some hours). Afterwards the new strings show up as "Remaining"

+To create the pull-request you have to do:

+        <source>Generated coins must mature 120 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, its state will change to &quot;not accepted&quot; and it won&apos;t be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>

-        <source>Generated coins must mature 120 blocks before they can be spent. When you generated this block, it was broadcast to the network to be added to the block chain. If it fails to get into the chain, it&apos;s state will change to &quot;not accepted&quot; and it won&apos;t be spendable. This may occasionally happen if another node generates a block within a few seconds of yours.</source>
