-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.

+Follow the instructions in [doc/release-process.md](release-process.md) in the bitcoin repository

+the next step: 'Seed the Gitian sources cache', which will fetch all necessary source files allowing

-I needed to add `--no-check-certificate` to the OpenSSL wget line to make it work.
-Likely this is because the ca-certificates in Debian 7.4 is fairly old. This does not create a 
-security issue as the gitian descriptors check the integrity of the input archives and refuse to work
-if any one is corrupted.
+Building Bitcoin
+----------------
 
-After downloading the archives, execute the `gbuild` commands to build the dependencies.
-This can take a long time, but only has to be done when the dependencies change, for example
-to upgrade the used version.
+To build Bitcoin (for Linux, OSX and Windows) just follow the steps under 'perform

-**Note**: Do not forget to copy the result from `build/out` to `inputs` after every gbuild command! This will save
-you a lot of time.
+This may take a long time as it also builds the dependencies needed for each descriptor.
+These dependencies will be cached after a successful build to avoid rebuilding them when possible.

 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`.
 
-```xml
-<qresource prefix="/translations">
-    <file alias="en">locale/bitcoin_en.qm</file>
-    ...
-</qresource>
+To automatically regenerate the `bitcoin_en.ts` file, run the following commands:
+```sh
+cd src/
+make translate
 ```
 
-### src/qt/locale/
+`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.
 
-This directory contains all translations. Filenames must adhere to this format:
+**Example Qt translation**
+```cpp
+QToolBar *toolbar = addToolBar(tr("Tabs toolbar"));
+```
 
-    bitcoin_xx_YY.ts or bitcoin_xx.ts
+### 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.
 
-#### bitcoin_en.ts (Source file)
+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.
 
-`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
+To create the pull-request, use the following commands:
+```
+git add src/qt/bitcoinstrings.cpp src/qt/locale/bitcoin_en.ts

-When new plurals are added to the source file, it's important to do the following steps:
+### 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.
 
-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
+You can find the Bitcoin translation project at [https://www.transifex.com/projects/p/bitcoin/](https://www.transifex.com/projects/p/bitcoin/).
 
-##### Creating the pull-request
+### 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)
 
-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.
+**For Linux and Mac**
 
-To create the pull-request you have to do:
+`pip install transifex-client`
 
-    git add src/qt/bitcoinstrings.cpp src/qt/locale/bitcoin_en.ts
-    git commit
+Setup your transifex client config as follows. Please *ignore the token field*.
 
-Syncing with Transifex
-----------------------
+```ini
+nano ~/.transifexrc
 
-We are using https://transifex.com as a frontend for translating the client.
+[https://www.transifex.com]
+hostname = https://www.transifex.com
+password = PASSWORD
+token =
+username = USERNAME
+```
 
-https://www.transifex.com/projects/p/bitcoin/resource/tx/
+**For Windows**
 
-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.
+Please see [http://docs.transifex.com/developer/client/setup#windows](http://docs.transifex.com/developer/client/setup#windows) for details on installation.
 
-Do not directly download translations one by one from the Transifex website, as we do a few
-postprocessing steps before committing the translations.
+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.
 
-### Fetching new translations
+### 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">
+    <file alias="en">locale/bitcoin_en.qm</file>
+    ...
+</qresource>
+```
+
+**Note:** that the language translation file **must end in `.qm`** (the compiled extension), and not `.ts`.
+
+### 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`.
+
+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.
