-Development tips and tricks
---------------------------
-
-**compiling for debugging**
-
-Run configure with the --enable-debug option, then make. Or run configure with
-CXXFLAGS="-g -ggdb -O0" or whatever debug flags you need.
-
-**debug.log**
-
-If the code is behaving strangely, take a look in the debug.log file in the data directory;
-error and debugging messages are written there.
-
-The -debug=... command-line option controls debugging; running with just -debug will turn
-on all categories (and give you a very large debug.log file).
-
-The Qt code routes qDebug() output to debug.log under category "qt": run with -debug=qt
-to see it.
-
-**testnet and regtest modes**
-
-Run with the -testnet option to run with "play bitcoins" on the test network, if you
-are testing multi-machine code that needs to operate across the internet.
-
-If you are testing something that can run on one machine, run with the -regtest option.
-In regression test mode, blocks can be created on-demand; see qa/rpc-tests/ for tests
-that run in -regtest mode.
-
-**DEBUG_LOCKORDER**
-
-Bitcoin Core is a multithreaded application, and deadlocks or other multithreading bugs
-can be very difficult to track down. Compiling with -DDEBUG_LOCKORDER (configure
-CXXFLAGS="-DDEBUG_LOCKORDER -g") inserts run-time checks to keep track of which locks
-are held, and adds warnings to the debug.log file if inconsistencies are detected.

 Setup
 ---------------------
 [Bitcoin Core](http://bitcoin.org/en/download) is the original Bitcoin client and it builds the backbone of the network. However, it downloads and stores the entire history of Bitcoin transactions (which is currently several GBs); depending on the speed of your computer and network connection, the synchronization process can take anywhere from a few hours to a day or more. Thankfully you only have to do this once. If you would like the process to go faster you can [download the blockchain directly](bootstrap.md).

+Development tips and tricks
+---------------------------
+
+**compiling for debugging**
+
+Run configure with the --enable-debug option, then make. Or run configure with
+CXXFLAGS="-g -ggdb -O0" or whatever debug flags you need.
+
+**debug.log**
+
+If the code is behaving strangely, take a look in the debug.log file in the data directory;
+error and debugging messages are written there.
+
+The -debug=... command-line option controls debugging; running with just -debug will turn
+on all categories (and give you a very large debug.log file).
+
+The Qt code routes qDebug() output to debug.log under category "qt": run with -debug=qt
+to see it.
+
+**testnet and regtest modes**
+
+Run with the -testnet option to run with "play bitcoins" on the test network, if you
+are testing multi-machine code that needs to operate across the internet.
+
+If you are testing something that can run on one machine, run with the -regtest option.
+In regression test mode, blocks can be created on-demand; see qa/rpc-tests/ for tests
+that run in -regtest mode.
+
+**DEBUG_LOCKORDER**
+
+Bitcoin Core is a multithreaded application, and deadlocks or other multithreading bugs
+can be very difficult to track down. Compiling with -DDEBUG_LOCKORDER (configure
+CXXFLAGS="-DDEBUG_LOCKORDER -g") inserts run-time checks to keep track of which locks
+are held, and adds warnings to the debug.log file if inconsistencies are detected.

 Translations
 ============

-The Bitcoin Core GUI can be easily translated into other languages. Here's how we
-handle those translations.
+The Bitcoin-Core project has been designed to support multiple localisations. This makes adding new phrases, and completely new languages easily achievable. For managing all application translations, Bitcoin-Core makes use of the Transifex online translation management tool. 

-Files and Folders
-----------------
+### Helping to translate (using Transifex)
+Transifex is setup to monitor the Github repo for updates, and when code containing new translations is found, Transifex will process any changes. It may take several hours after a pull-request has been merged, to appear in the Transifex web interface.

-### bitcoin-qt.pro
+Multiple language support is critical in assisting Bitcoin’s global adoption, and growth. One of Bitcoin’s greatest strengths is cross-boarder money transfers, any help making that easier is greatly appreciated.

-This file takes care of generating `.qm` files from `.ts` files. It is mostly
-automated.
+See the [Transifex Bitcoin project](https://www.transifex.com/projects/p/bitcoin/) to assist in translations. You should also join the translation mailing list for announcements - see details below.

-### src/qt/bitcoin.qrc
+### Writing code with translations
+We use automated scripts to help extract translations in both Qt, and non-Qt source files. It is rarely necessary to manually edit the files in `src/qt/locale/`. The translation source files must adhere to the following format:
+`bitcoin_xx_YY.ts or bitcoin_xx.ts`

-This file must be updated whenever a new translation is added. Please note that
-files must end with `.qm`, not `.ts`.
+`src/qt/locale/bitcoin_en.ts` is treated in a special way. It is used as the source for all other translations. Whenever a string in the source code is changed, this file must be updated to reflect those changes. A custom script is used to extract strings from the non-Qt parts. This script makes use of `gettext`, so make sure that utility is installed (ie, `apt-get install gettext` on Ubuntu/Debian). Once this has been updated, `lupdate` (included in the Qt SDK) is used to update `bitcoin_en.ts`.
+
+To automatically regenerate the `bitcoin_en.ts` file, run the following commands:
+```sh
+cd src/
+make translate
+```
+
+`contrib/bitcoin-qt.pro` takes care of generating `.qm` (binary compiled) files from `.ts` (source files) files. It’s mostly automated, and you shouldn’t need to worry about it.
+
+**Example Qt translation**
+```cpp
+QToolBar *toolbar = addToolBar(tr("Tabs toolbar"));
+```
+
+### Creating a pull-request
+For general PRs, you shouldn’t include any updates to the translation source files. They will be updated periodically, primarily around pre-releases, allowing time for any new phrases to be translated before public releases. This is also important in avoiding translation related merge conflicts.
+
+When an updated source file is merged into the Github repo,  Transifex will automatically detect it (although it can take several hours). Once processed, the new strings will show up as "Remaining" in the Transifex web interface and are ready for translators.
+
+To create the pull-request, use the following commands:
+```
+git add src/qt/bitcoinstrings.cpp src/qt/locale/bitcoin_en.ts
+git commit
+```
+
+### Creating a Transifex account
+Visit the [Transifex Signup](https://www.transifex.com/signup/) page to create an account. Take note of your username and password, as they will be required to configure the command-line tool.
+
+You can find the Bitcoin translation project at [https://www.transifex.com/projects/p/bitcoin/](https://www.transifex.com/projects/p/bitcoin/).
+
+### Installing the Transifex client command-line tool
+The client it used to fetch updated translations. If you are having problems, or need more details, see [http://docs.transifex.com/developer/client/setup](http://docs.transifex.com/developer/client/setup)
+
+**For Linux and Mac**
+
+`pip install transifex-client`
+
+Setup your transifex client config as follows. Please *ignore the token field*.
+
+```ini
+nano ~/.transifexrc
+
+[https://www.transifex.com]
+hostname = https://www.transifex.com
+password = PASSWORD
+token =
+username = USERNAME
+```
+
+**For Windows**
+
+Please see [http://docs.transifex.com/developer/client/setup#windows](http://docs.transifex.com/developer/client/setup#windows) for details on installation.
+
+The Transifex Bitcoin project config file is included as part of the repo. It can be found at `.tx/config`, however you shouldn’t need change anything.
+
+### Synchronising translations
+To assist in updating translations, we have created a script to help.
+
+1. `python contrib/devtools/update-translations.py`
+2. Update `src/qt/bitcoin.qrc` manually or via
+   `ls src/qt/locale/*ts|xargs -n1 basename|sed 's/\(bitcoin_\(.*\)\).ts/<file alias="\2">locale\/\1.qm<\/file>/'`
+3. Update `src/qt/Makefile.am` manually or via
+   `ls src/qt/locale/*ts|xargs -n1 basename|sed 's/\(bitcoin_\(.*\)\).ts/  locale\/\1.ts \\/'`
+4. `git add` new translations from `src/qt/locale/`
+
+**Do not directly download translations** one by one from the Transifex website, as we do a few post-processing steps before committing the translations.
+
+### Handling Plurals (in source files)
+When new plurals are added to the source file, it's important to do the following steps:
+
+1. Open `bitcoin_en.ts` in Qt Linguist (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
+
+### Translating a new language
+To create a new language template, you will need to edit the languages manifest file `src/qt/bitcoin.qrc` and add a new entry. Below is an example of the english language entry.

 ```xml
 <qresource prefix="/translations">
@ -24,66 +103,9 @@ files must end with `.qm`, not `.ts`.
 </qresource>
 ```

-### src/qt/locale/
+**Note:** that the language translation file **must end in `.qm`** (the compiled extension), and not `.ts`.

-This directory contains all translations. Filenames must adhere to this format:
+### Questions and general assistance
+The Bitcoin-Core translation maintainers include *tcatm, seone, Diapolo, wumpus and luke-jr*.You can find them, and others, in the Freenode IRC chatroom - `irc.freenode.net #bitcoin-dev`.

-    bitcoin_xx_YY.ts or bitcoin_xx.ts
-
-#### bitcoin_en.ts (Source file)
-
-`src/qt/locale/bitcoin_en.ts` is treated in a special way. It is used as the
-source for all other translations. Whenever a string in the code is changed
-this file must be updated to reflect those changes. A  custom script is used
-to extract strings from the non-Qt parts. This script makes use of `gettext`,
-so make sure that utility is installed (ie, `apt-get install gettext` on 
-Ubuntu/Debian). Once this has been updated, lupdate (included in the Qt SDK)
-is used to update bitcoin_en.ts. This process has been automated, from src/qt,
-simply run:
-    make translate
-    
-##### Handling of plurals in the source file
-
-When new plurals are added to the source file, it's important to do the following steps:
-
-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
-
-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"
-in Transifex and can be translated.
-
-To create the pull-request you have to do:
-
-    git add src/qt/bitcoinstrings.cpp src/qt/locale/bitcoin_en.ts
-    git commit
-
-Syncing with Transifex
----------------------
-
-We are using https://transifex.com as a frontend for translating the client.
-
-https://www.transifex.com/projects/p/bitcoin/resource/tx/
-
-The "Transifex client" (see: http://support.transifex.com/customer/portal/topics/440187-transifex-client/articles)
-is used to fetch new translations from Transifex. The configuration for this client (`.tx/config`)
-is part of the repository.
-
-Do not directly download translations one by one from the Transifex website, as we do a few
-postprocessing steps before committing the translations.
-
-### Fetching new translations
-
-1. `python contrib/devtools/update-translations.py`
-2. update `src/qt/bitcoin.qrc` manually or via
-   `ls src/qt/locale/*ts|xargs -n1 basename|sed 's/\(bitcoin_\(.*\)\).ts/<file alias="\2">locale\/\1.qm<\/file>/'`
-3. update `src/qt/Makefile.am` manually or via
-   `ls src/qt/locale/*ts|xargs -n1 basename|sed 's/\(bitcoin_\(.*\)\).ts/  locale\/\1.ts \\/'`
-4. `git add` new translations from `src/qt/locale/`
+If you are a translator, you should also subscribe to the mailing list, https://groups.google.com/forum/#!forum/bitcoin-translators. Announcements will be posted during application pre-releases to notify translators to check for updates.
