If you want to translate Fab-manager to a new language, just send us an email to [contact@fab-manager.com](mailto:contact@fab-manager.com) and we'll add this new language to the TMS.
To translate the front-end application (angularJS client), and the notifications, you can use [Crowdin In-Context](https://crowdin.com/page/in-context-localization).
First, consider that it can be a good idea to setup a development environment to contribute to the software translation.
This is not mandatory, but this will allow you to test your changes in context and see if anything went wrong, especially with the special syntaxes.
Please refer to the [development readme](development_readme.md) or to the [virtual machine instructions](virtual-machine.md) to setup such an environment.
Once done, check the files located in `config/locales`:
- Front app translations (angular.js) are located in `config/locales/app.scope.XX.yml`.
Where scope has one the following meaning :
- admin: translations of the administrator views (manage and configure the FabLab).
- logged: translations of the end-user's views accessible only to connected users.
- public: translation of end-user's views publicly accessible to anyone.
- shared: translations shared by many views (like forms or buttons).
- Back app translations (Ruby on Rails) are located in `config/locales/XX.yml`.
- Emails translations are located in `config/locales/mails.XX.yml`.
- Messages related to the authentication system are located in `config/locales/devise.XX.yml`.
If you plan to translate the application to a new locale, please consider that the reference translation is French.
Indeed, in some cases, the English texts/sentences can seems confuse or lack of context as they were originally translated from French.
To prevent syntax mistakes while translating locale files, we **STRONGLY advise** you to use a text editor which support syntax coloration for YML and Ruby.
As an example, [Visual Studio Code](https://code.visualstudio.com/), with the [Ruby extension](https://marketplace.visualstudio.com/items?itemName=rebornix.Ruby) and the [YAML extension](https://marketplace.visualstudio.com/items?itemName=redhat.vscode-yaml) will do the job.
Front-end translations uses [angular-translate](http://angular-translate.github.io) with interpolations interpreted by [MessageFormat](https://github.com/SlexAxton/messageformat.js/).
**Please read the documentation about the [ICU MessageFormat syntax](http://userguide.icu-project.org/formatparse/messages#TOC-MessageFormat) before translating.**
Back-end translations uses the [Ruby on Rails syntax](http://guides.rubyonrails.org/i18n.html) but some complex interpolations are interpreted by [MessageFormat](https://github.com/format-message/message-format-rb) and are marked as it in comments.
**DO NOT confuse the syntaxes.**
In each cases, some inline comments are included in the localisation files.
They can be recognized as they start with the sharp character (#).
These comments are not required to be translated, they are intended to help the translator to have some context information about the sentence to translate.
You will also need to translate the invoice watermark, located in `app/pdfs/data/`.
You'll find there the [GIMP source of the image](app/pdfs/data/watermark.xcf), which is using [Rubik Mono One](https://fonts.google.com/specimen/Rubik+Mono+One) as font.
Use it to generate a similar localised PNG image which keep the default image size, as PDF are not responsive.
