Build Status

How To Participate

Bitcoin.org needs volunteers like you! Here are some ways you can help:

You can always report problems or help improve bitcoin.org by opening a new issue or pull request on GitHub.

Working With GitHub

GitHub allows you to make changes to a project using git, and later submit them in a "pull request" so they can be reviewed and discussed. Many online how-tos exist so you can learn git, here's a good one.

In order to use GitHub, you need to sign up and set up git. You will also need to click the Fork button on the bitcoin.org GitHub page and clone your GitHub repository into a local directory with the following command lines:

git clone (url provided by GitHub on your fork's page) bitcoin.org
cd bitcoin.org
git remote add upstream https://github.com/bitcoin-dot-org/bitcoin.org.git

How to send a pull request

  1. Checkout to your master branch. git checkout master
  2. Create a new branch from the master branch. git checkout -b (any name)
  3. Edit files and preview the result.
  4. Track changes in files. git add -A
  5. Commit your changes. git commit -m '(short description for your change)'
  6. Push your branch on your GitHub repository. git push origin (name of your branch)
  7. Click on your branch on GitHub and click the Compare / pull request button to send a pull request.

When submitting a pull request, please take required time to discuss your changes and adapt your work. It is generally a good practice to split unrelated changes into separate branchs and pull requests.

Travis Continuous Integration (CI)

Shortly after your Pull Request (PR) is submitted, a Travis CI job will be added to our queue. This will build the site and run some basic checks. If the job fails, you will be emailed a link to the build log and the PR will indicate a failed job. Read the build report and try to correct the problem---but if you feel confused or frustrated, please ask for help on the PR (we're always happy to help).

If you don't want a particular commit to be tested, add [ci skip] anywhere in its commit message.

If you'd like to setup Travis on your own repository so you can test builds before opening a pull request, it's really simple:

  1. Make sure the master branch of your repository is up to date with the bitcoin-dot-org/bitcoin.org master branch.

  2. Open this guide and perform steps one, two, and four. (The other steps are already done in our master branch.)

  3. After you push a branch to your repository, go to your branches page (e.g. for user harding, github.com/harding/bitcoin.org/branches). A yellow circle, green checkmark, or red X will appear near the branch name when the build finishes, and clicking on the icon will take you to the corresponding build report.

How to make additional changes in a pull request

You simply need to push additional commits on the appropriate branch of your GitHub repository. That's basically the same steps as above, except you don't need to re-create the branch and the pull request.

How to reset and update your master branch with latest upstream changes

  1. Fetch upstream changes. git fetch upstream
  2. Checkout to your master branch. git checkout master
  3. Replace your master branch by the upstream master branch. git reset --hard upstream/master
  4. Replace your master branch on GitHub. git push origin master -f

Advanced GitHub Workflow

If you continue to contribute to Bitcoin.org beyond a single pull request, you may want to use a more advanced GitHub workflow.

Previewing

Preview Small Text Changes

Simple text changes can be previewed live on bitcoin.org. You only need to click anywhere on the page and hold your mouse button for one second. You'll then be able to edit the page just like a document. Changes will be lost as soon as the page is refreshed.

Build The Site Locally

For anything more than simple text previews, you will need to build the site. If you can't do this yourself using the instructions below, please open a pull request with your suggested change and one of the site developers will create a preview for you.

To build the site, you need to go through a one-time installation procedure that takes 15 to 30 minutes. After that you can build the site an unlimited number of times with no extra work.

Install The Dependencies

Before building the site, you need to install the following dependencies and tools, which are pretty easy on any modern Linux:

Install binary libraries and tools

On recent versions of Ubuntu and Debian, you can run the following command to ensure you have the required libraries, headers, and tools:

sudo apt-get install build-essential git libicu-dev zlib1g-dev

Install RVM

Install RVM using either the easy instructions or the more secure instructions.

Read the instructions printed to your console during setup to enable the rvm command in your shell. After installation, you need to run the following command:

source ~/.rvm/scripts/rvm

Install Ruby 2.0.0

To install Ruby 2.0.0, simply run this command:

rvm install ruby-2.0.0

Sometimes this will find a pre-compiled Ruby package for your Linux distribution, but sometimes it will need to compile Ruby from scratch (which takes about 15 minutes).

After Ruby 2.0.0 is installed, make it your default Ruby:

rvm alias create default ruby-2.0.0

And tell your system to use it:

rvm use default

(Note: you can use a different default Ruby, but if you ever change your default Ruby, you must re-run the gem install bundle command described below before you can build the site. If you ever receive a "eval: bundle: not found" error, you failed to re-run gem install bundle.)

Install Bundle

When you used RVM to install Ruby, it also installed the gem program. Use that program to install bundle:

gem install bundle

Install the Ruby dependencies

Ensure you checked out the site repository as described in Working with GitHub. Then change directory to the top-level of your local repository (replace bitcoin.org with the full path to your local repository clone):

cd bitcoin.org

And install the necessary dependencies using Bundle:

bundle install

Note that some of the dependencies (particularly nokogiri) can take a long time to install on some systems, so be patient.

Once Bundle completes successfully, you can preview or build the site.

Preview The Site

To preview the website in your local browser, make sure you're in the bitcoin.org directory and run the following command:

make preview

This will compile the site (takes 5 to 10 minutes; see the speed up instructions) and then print the a message like this:

Server address: http://0.0.0.0:4000
Server running... press ctrl-c to stop.

Visit the indicated URL in your browser to view the site.

Build The Site

To build the site exactly like we do for the deployment server, make sure you're in the bitcoin.org directory and run:

make

The resulting HTML for the entire site will be placed in the _site directory. The following alternative options are available:

## After you build the site, you can run all of the tests (may take awhile)
make test

## Or you can build the site and run some quick tests with one command:
make valid

## Or build the site and run all tests
make all

Fast Partial Previews Or Builds

In order to preview some changes faster, you can disable all plugins and languages except those you need by prefixing the ENABLED_LANGS and ENABLED_PLUGINS environment variables to your command line. For example, do this to disable everything:

## Fast preview, takes less than 30 seconds
ENABLED_PLUGINS="" ENABLED_LANGS="" make preview

## Fast build and tests, takes less than 50 seconds
## Some tests may fail in fast mode; use -i to continue despite them
ENABLED_PLUGINS="" ENABLED_LANGS="" make -i valid

Then to enable some plugins or languages, you can add them back in. For example:

## Slower (but still pretty fast) build and test
ENABLED_PLUGINS="events autocrossref" ENABLED_LANGS="en fr" make -i valid

Plugins include:

Plugin Seconds Remote APIs Used For
alerts 5 -- Network alert pages
autocrossref 90 -- Developer documentation
contributors 5 GitHub.com Contributor listings
events 5 Meetup.com; Google Maps Events page
glossary 30 -- Developer glossary
redirects 20 -- Redirects from old URLs
releases 10 -- Bitcoin Core release notes; Download page
sitemap 10 -- /sitemap.xml

Notes: some plugins interact with each other or with translations; for example running 'autocrossref' and 'glossary' takes longer than running each other separately. Also, plugins that use remote APIs may take a long time to run if the API site is running slow.

For a list of languages, look in the _translations directory.

Developer Documentation

Most parts of the documentation can be found in the _includes directory. Updates, fixes and improvements are welcome and can submitted using pull requests on GitHub.

Mailing List: General discussions can take place on the mailing list.

TODO List: New content and suggestions for improvements can be submitted to the TODO list. You are also welcome if you want to assign yourself to any task.

Style Guide: For better consistency, the style guide can be used as a reference for terminology, style and formatting. Suggested changes can also be submitted to this guide to keep it up to date.

Cross-Reference Links: Cross-reference links can be defined in _includes/references.md. Terms which should automatically link to these references are defined in _autocrossref.yaml .

New Glossary Entries

Add new English glossary entries in the _data/glossary/en/ directory. Copy a previous glossary entry to get the correct YAML variables (suggest using block.yaml as a template).

Non-English glossary entries are not currently supported. You'll have to update the glossary.rb plugin and templates to support them.

New Developer Search terms

You can add new search terms or categories directly to the devsearches array in _config.yaml. Comments in that file should provide full documentation.

Translation

How To Translate

You can join a translation team on Transifex and start translating or improving existing translations.

  • You must be a native speaker for the language you choose to translate.
  • Please be careful to preserve the original meaning of each text.
  • Sentences and popular expressions should sound native in your language.
  • You can check the result on the live preview and test small changes.
  • Translations need to be reviewed by a reviewer or coordinator before publication.
  • Once reviewed, translations can be submitted in a pull request on GitHub.
  • In doubt, please contact coordinators on Transifex. That'll be much appreciated.

Import Translations

Update translations: You can update the relevant language file in _translations/ and from the root of the git repository run ./_contrib/updatetx.rb to update layouts and templates for this language. You should also make sure that no url has been changed by translators. If any page needs to be moved, please add redirections.

Add a new language: You can put the language file from Transifex in _translations and add the language in _config.yml in the right display order for the language bar. Make sure to review all pages and check all links.

Update English Strings

Any change in the English text can be done through a pull request on GitHub. If your changes affect the HTML layout of a page, you should apply fallback HTML code for other languages until they are updated.

{% case page.lang %}
{% when 'fr' %}
  (outdated french content)
{% else %}
  (up to date english content)
{% endcase %}

When translation is needed: If you want all changes you've made to be re-translated, you can simply update the resource file (en.yml) on Transifex.

When translation is not needed: If you are only pushing typo fixes and that you don't want translators to redo all their work again, you can use the Transifex client to pull translations, update en.yml and push back all translations at once:

tx init
tx set --auto-remote https://www.transifex.com/projects/p/bitcoinorg/
tx pull -a -s --skip
tx set --source -r bitcoinorg.bitcoinorg -l en translations/bitcoinorg.bitcoinorg/en.yml
(update en.yml)
tx push -s -t -f --skip --no-interactive

Posts

Events

If you're not comfortable with GitHub pull requests, please submit an event using the button near the bottom of the Events page.

To create an event pull request, place the event in _events.yml and adhere to this format:

- date: 2014-02-21
  title: "2014 Texas Bitcoin Conference"
  venue: "Circuit of the Americas™ - Technology and Conference Center"
  address: "9201 Circuit of the Americas Blvd"
  city: "Austin, TX"
  country: "United States"
  link: "http://texasbitcoinconference.com/"

Events that have a Meetup.com page with a publicly-viewable address and "Bitcoin" in the event title should already be displayed on the events page. (Please open a new issue if a Bitcoin meetup event isn't displayed.)

Release Notes

To create a new Bitcoin Core release, create a new file in the _releases/ directory. Any file name ending in .md is fine, but we recommend naming it after the release, such as 0.10.0.md

Then copy in the following YAML header (the part between the three dashes, ---):

---
## Required value below populates the %v variable (note: % needs to be escaped in YAML if it starts a value)
required_version: 0.10.0
## Optional release date.  May be filled in hours/days after a release
optional_date: 2015-02-16
## Optional title.  If not set, default is: Bitcoin Core version %v released
optional_title: Bitcoin Core version %v released
## Optional magnet link.  To get it, open the torrent in a good BitTorrent client
## and View Details, or install the transmission-cli Debian/Ubuntu package
## and run: transmission-show -m <torrent file>
#
## Link should be enclosed in quotes and start with: "magnet:?
optional_magnetlink:

## The --- below ends the YAML header. After that, paste the release notes.
## Warning: this site's Markdown parser commonly requires you make two
## changes to the release notes from the Bitcoin Core source tree:
##
## 1. Make sure both ordered and unordered lists are preceeded by an empty
## (whitespace only) line, like the empty line before this list item.
##
## 2. Place URLs inside angle brackets, like <http://bitcoin.org/bin>

---

Then start at the top of the YAML header and read the comments, filling in and replacing information as necessary, and then reformatting the release notes (if necessary) as described by the last lines of the YAML header.

Download links will automatically be set to the defaults using the current release version number, but if you need to change any download URL, edit the file _templates/download.html

You can then create a pull request to the master branch and Travis CI will automatically build it and make sure the links you provided return a "200 OK" HTTP header. (The actual files will not be downloaded to save bandwidth.) Alternatively, you can build the site locally with make all to run the same quality assurance tests.

The file can be edited later to add any optional information (such as a release date) that you didn't have when you created the file.

Preparing a release in advance

It's nice to prepare a release pull request in advance so that the Bitcoin Core developers can just click "Merge Pull Request" when the new version is released. Here's the recommended recipe, where <VERSION> is the particular version:

  1. Create a new branch named bitcoin-core-<VERSION>. You can either do this locally or in GitHub's web GUI.

  2. Follow the instructions in the [Release Notes][] section to create a new release. You should leave the optional_date blank unless you happen to know the date of the planned release.

  3. Push the branch to the https://github.com/bitcoin-dot-org/bitcoin.org repository so any contributor can edit it. Don't open a pull request yet.

  4. Travis CI will build the site from the branch and then run the tests. The tests will fail because they expect the release binaries to be present and you're preparing this release request in advance of them being uploaded.

  5. Open the failed Travis CI log. At the end, it will say something like:

    ERROR:
    Error: Could not retrieve /bin/bitcoin-core-0.10.1/bitcoin-0.10.1-win64-setup.exe
    Error: Could not retrieve /bin/bitcoin-core-0.10.1/bitcoin-0.10.1-win32-setup.exe
    [...]
    
  6. Copy the errors from above into a text file and remove everything except for the URLs so that what's left are lines that look like:

    /bin/bitcoin-core-0.10.1/bitcoin-0.10.1-win64-setup.exe
    /bin/bitcoin-core-0.10.1/bitcoin-0.10.1-win32-setup.exe
    [...]
    
  7. Optional, but nice: sort the lines into alphabetical order.

  8. Now open a pull request from the bitcoin-core-<VERSION> branch to the master branch. We recommend that you use this title: "Releases: Add Bitcoin Core <VERSION>".

    We recommend that you use the following text with any changes you think are appropriate. Note: read all the way to the end of this enumerated point before submitting your pull request.

    This updates the download links to point to <VERSION> and adds the
    <VERSION> release notes to the site. I'll keep it updated throughout
    the RC cycle, but it can be merged by anyone with commit access
    once <VERSION> final is released (see TODO lists below).
    
    CC: @laanwj
    
    Essential TODO:
    
    * [ ] Make sure the download links work. This is automatically checked as part of the Travis CI build, so trigger a rebuild and, if it passes, this should be safe to merge.
    
    Optional TODO (may be done in commits after merge):
    
    * [ ] Add the actual release date to the YAML header in `_releases/0.10.1.md`
    * [ ] Add the magnet URI to the YAML header in `_releases/0.10.1.md` (brief instructions for creating the link are provided as comments in that file)
    
    Expected URLs for the Bitcoin Core binaries:
    

    Underneath the line 'Expected URLs', paste the URLs you retrieved from Travis CI earlier.

    Note that @laanwj is Wladimir J. van der Laan, who is usually responsible for uploading the Bitcoin Core binaries. If someone else is responsible for this release, CC them instead. If you don't know who is responsible, ask in #bitcoin-dev on Freenode.

  9. After creating the pull request, use the Labels menu to assign it the "Releases" label. This is important because it's what the Bitcoin Core release manager will be looking for.

  10. After each new Release Candidate (RC) is released, update the release notes you created in the _releases directory. (But don't worry about this too much; we can always upload updated release notes after the release.)

Alerts

Network alerts should be placed in _alerts/YYYY-MM-DD-SHORTITLE.html and adhere to this format:

---
title: "11/12 March 2013 Chain Fork"
alias: "chainfork"
active: true
banner: "<b>Chain fork</b> - Please stop mining on bitcoin version 0.8.0. Click here for more information."
---

<p>

      • Encrypt the wallet by default
  • For hardware wallets:
    • Prevents downgrading the firmware

Adding a wallet

Before adding a wallet, please make sure your wallet meets all of the Basic Requirements listed above, or open a new issue to request an exemption or policy change. Feel free to email Dave Harding dave@dtrt.org if you have any questions.

Wallets can be added in _templates/choose-your-wallet.html. Entries are ordered by levels and new wallets must be added after the last wallet on the same level.

  • Level 1 - Full nodes
  • Level 2 - SPV, Random servers
  • Level 3 - Hybrid, Multisig wallets
  • Level 4 - Web wallets

Screenshot: The png files must go in /img/screenshots, be 250 X 350 px and optimized with optipng -o7 file.png.

Icon: The png file must go in /img/wallet, be 144 X 144 px and optimized with optipng -o7 file.png. The icon must fit within 96 X 96 px inside the png, or 85 X 85 px for square icons.

Description: The text must go in _translations/en.yml alongside other wallets' descriptions.

Score

Each wallet is assigned a score for five criterias. For each of them, the appropriate text in _translations/en.yml needs to be choosen.

Control - What control the user has over his bitcoins?

To get a good score, the wallet must provide the user with full exclusive control over their bitcoins.

To get a passing score, the wallet must provide the user with exclusive control over their bitcoins. Encrypted online backups are accepted so long as only the user can decrypt them. Multisig wallets are accepted so long as only the user can spend without the other party's permission.

Validation - How secure and « zero trust » is payment processing?

To get a good score, the wallet must be a full node and need no trust on other nodes.

To get a passing score, the wallet must rely on random nodes, either by using the SPV model or a pre-populated list or servers.

Transparency - How transparent and « zero trust » is the source code?

To get a good score, the wallet must deserve a passing score and be built deterministically.

To get a passing score, the wallet must be open-source, under version control and releases must be clearly identified (e.g. by tags or commits). The codebase and final releases must be public since at least 6 months and previous commits must remain unchanged.

Environment - How secure is the environment of the wallet?

To get a good score, the wallet must run from an environment where no apps can be installed.

To get a passing score, the wallet must run from an environment that provides app isolation (e.g. Android, iOS), or require two-factor authentication for spending.

Privacy: Does the wallet protect users' privacy?

To get a good score, the wallet must avoid address reuse by using a new change address for each transaction, avoid disclosing information to peers or central servers and be compatible with Tor.

To get a passing score, the wallet must avoid address reuse by using a new change address for each transaction.

Blog Posts

Posts for the [Bitcoin.org Site Blog][] should be added to the _posts directory with the naming convention: YEAR-MONTH-DAY-ARBITRARY_FILE_NAME (with year, month, and day as two-digit numbers). The YAML front matter should be similar to this:

---
type: posts
layout: post
lang: en
category: blog

title: "Quarterly Report March 2015"
permalink: /en/posts/quarterly-report-march-2015.html
date: 2015-03-05
author: >
  David A. Harding (<a href="mailto:dave@dtrt.org">email</a>, <a
  href="https://github.com/harding">GitHub</a>,
  <a href="http://www.reddit.com/user/harda/">Reddit</a>)
---

The type, layout, and category should always be as specified above. The other parameters should be set to values specific to that post, but the permalink must end in '.html'.

Below the YAML front matter, enter the content of the post in Markdown format. Images should be placed in img/blog/free if they are MIT-licensed or img/blog/nonfree if they have a more restrictive copyright license.
