How To Participate

You can report problems or help improve bitcoin.org by opening an issue or a pull request on GitHub. You can also help by translating bitcoin.org's text on Transifex.

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/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.

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

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 Site With Jekyll From Bundler

Make sure you have ruby 2.0. If you don't, we recommend installing it with RVM, which can usually be done by running the following three commands:

\curl -sSL https://get.rvm.io | bash -s stable
source ~/.rvm/scripts/rvm
rvm install ruby-2.0.0

Next, you need to install bundler, and let it install all gems you need to build the site. You must run the last command from within your local bitcoin.org repository:

gem install bundler
bundle install

Finally, you can build the website in _site/:

bundle exec jekyll build

You can then copy the output files from _site/ to the root of your web server. If you have no web server, run bundle exec jekyll serve and visit http://127.0.0.1:4000/. This server requires you to add a trailing ".html" by hand in your browser address bar.

Build Site With Jekyll From APT

The instructions in the section above will ensure that you use the same versions of the same software we use to build the website, but you can also install dependencies from your Linux distribution. For example:

Installing dependencies on Ubuntu 12.10:

sudo apt-get install jekyll node-less ruby1.9.1-dev libicu-dev
sudo gem install ffi-icu

Installing dependencies on older Ubuntu and Debian distributions:

sudo apt-get install rubygems ruby1.9.1-dev build-essential libicu-dev
sudo gem install jekyll json less therubyracer ffi-icu

Finally build the website in _site/:

jekyll

...Or jekyll build on recent versions. You can then copy the output files from _site/ to the root of your web server. If you have no web server, run jekyll --server (or jekyll serve on recent versions) and visit http://127.0.0.1:4000/. This server requires you to add a trailing ".html" by hand in your browser address bar.

Building With Make

After you've installed Jekyll and the other dependencies, you can optionally use GNU Make to automatically build the site and run several tests. You will first need to install Make using your package manager; for example:

sudo apt-get install make

Then in your local bitcoin.org repository, run one of the following commands:

## To just build the site, the equivalent of: bundle exec jekyll build
make

## 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

Developer Documentation

Each part 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 .

Translation

How To Translate

You can join a translation team on Transifex and start translating or improving existing translations. Latest live previews and communications can be found on this thread.

  • 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 live previews 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 open a discussion on Transifex with coordinators. 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

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.

Decentralization - 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 rotate addresses, avoid disclosing information to peers or central servers and be compatible with Tor.

To get a passing score, the wallet must rotate addresses.
