+
+https://www.transifex.com/[Transifex] is a web platform allowing collaborative translation work.
+
+The translation project of the Valentina GUI interface is hosted https://app.transifex.com/valentina/valentina-project/dashboard/[here].
+
+English(en) is the langue source, 32 other languages are supported in the project, see https://app.transifex.com/valentina/valentina-project/languages/[the list].
+
+Thus prerequisites are: you speak both English and another or several of the 32 supported languages, and you understand Valentina interface enough to translate strings.
+
+All functions available in Transifex won't be explored here, please refer for complete and further information to the documentation guides https://help.transifex.com/en/[here], it provides https://help.transifex.com/en/collections/3441044-starting-with-the-basics[many ressources to begin as a translator].
+
+# Joining the translation team.
+
+Joining the Valentina translation team is very simple: you just have to register in Transifex and ask to join the team.
+
+
+## Creating an account in Transifex.
+
+Sign up https://www.transifex.com/signup/[here], and follow instructions:
+
+* You'll be required to activate the account with the link provided in the email confirmation
+* you'll have to choose your job role: "translator".
+
+=== Joining the translation team. ===
+
+Unless you were directly invited by the translation team by email, you'll have to ask to join the project during the registration step:
+
+* clik on "Join an existing project", search for "valentina" in the explore page, ask to join and choose in which language you will translate.
+* you'll have to be approved before joining the team, please wait for the confirmation email.
+
+
+<<<
+
+== Configuring your account and preferences.
+
+You can set up some specific preferences in the main dashboard as well as in the user settings page of your personal account:
+
+The GUI language (Transifex interface) is provided in your language by default.
+
+Click on the ? icon at the bottom of the left sidebar to change the Transifex interface language.
+
+You can then switch to another language :
+
+image::switch-transifex-gui-language.png[]
+
+
+Click on the project icon at the bottom of the left sidebar to acess to your profile, there you can set up:
+
+* personal credentials,
+* notification settings, if you don't want to be notified absolutely every project or translation change,
+* sign in settings,
+* etc.
+
+== Staff status in the team.
+
+There are 4 main status in the project's translation teams:
+
+* admin = Roman Telezhinkyi, id @dismine
+* coordinators: 23 presently, they manage a translation team in a specific language, they have the specific permissions for accepting and excluding members from the project, plus they are translators and reviewers at the same time,
+* reviewers: can translate non translated strings and also review translated ones,
+* translators: can only translate non translated strings.
+
+Thus, if you have the translator status, don't try to review strings, please:
+
+- Translate what has not been translated yet
+- Comment reviewed strings if you identified some issue, 'Comment' tab, tag in your comment @dismine for admin or @your_coordinator_id, so they can be notified your comment.
+
+
+<<<
+
+== Translating.
+
+=== Accessing to the groups of ressources.
+
+On the project dashboard, click on "Translate" (the button is provided in the language you set up for Transifex interface).
+
+In the translate board, select your language:
+
+
+
+You get access to a page displaying all groups of ressources.
+
+All groups of ressources are provided without any filter :
+
+* first, the group "valentina.ts" for Valentina last 0.7 version,
+* then the group "valentina_0.6.x.ts" for Valentina 0.6 version.
+
+Information is also displayed about the number of strings which are not translated / reviewed yet.
+
+image::priority-tag.png[]
+
+Let's choose by default to translate "valentina.ts".
+
+
+=== Filtering.
+
+Using filters is very important, otherwise translation of strings will be soon discouraging.
+
+The page we have accessed to displays all strings of the group of ressources, you can switch to 'non translated' or 'non reviewed' pages in the top menu.
+
+image::valentina-ts-all.png[]
+
+Let's go to the 'non translated' strings page.
+
+You can see that a first condition has appeared in the filters bar: _"translated:no"_.
+
+image::not-translated-strings.png[]
+
+You could have accessed to all non translated strings by entering manually _"translated:no"_ in the filters bar, or by selecting "status - translated - no" in the filters menu:
+
+image::filters-menu.png[]
+
+If you watch the list of strings you obtain now, this is still a mess of unsorted words and expressions without any apparent logics.
+
+So let's filter further.
+
+At this step, launch Valentina and set the interface language in English in the Preferences settings.
+
+In the Transifex page, click on the first non-translated string (at your convenience).
+
+I have clicked on the string 'Passmark length:'
+
+image::string-passmark_length.png[]
+
+Rather than translating right away, let's look at the Context field provided in the center panel. The context is here _DialogPatternProperties_.
+
+This provides us 2 important pieces of information:
+
+* the string is extracted from the pattern properties dialog box in Valentina,
+* we can translate all strings of this dialog box at the same time by filtering in context.
+
+
+=== Translating.
+
+Let's now enter in the filters bar in order to translate in context: _context:DialogPatternProperties translated:no_.
+
+Enter the translation and save.
+
+image::string_passmark-length_translation.png[]
+
+*When translated, a turquoise circle must appear in front of the string.*
+
+
+=== Syntax and punctuation.
+
+Please keep in mind that *some characters and punctuation are very important to keep* when translating.
+
+For example, in such a string:
+
+image::characters-1.png[]
+
+First copy and paste source strings by clicking on 'Copy source string' in the translation panel:
+
+image::copy-source-string.png[]
+
+Such pre-formatted blocks must be kept as they are:
+
+image::string-blocks.png[]
+
+Punctuation must not be erased either changed (don't add neither delete spaces):
+
+image::string-punctuation.png[]
+
+Here is how the translation must look:
+
+image::string-appropriate-translation.png[]
+
+
+=== Issues.
+
+If you encounter a specific issue with your permissions in the team or with the interface, please contact the admin *in English* (click on your avatar - Messages - Compose).
+
+If you are not sure how to translate a specific string, while being placed in this string, add an issue *in English* (in the right panel), you will be answered at the same place (and notified you received an answer according to your personal notification settings).
+
+
+=== Comments.
+
+You can as well comment your translation (in the right panel too).
+
+WARNING: Please don't use 'comments' to report an issue, but only to ask advice to your coordinator or explain to the team why you choose some terms, for example.
+
+
+== Reviewing (for reviewers only).
+
+Let's now enter in the filters bar: _context:DialogPatternProperties reviewed:no_. (don't keep the _translated:no_ filter).
+
+I obtain about 40 non reviewed strings, the first one is 'Pattern properties'.
+
+image::string-pattern_properties.png[]
+
+The center and right panels provide many information:
+
+* who translated and when,
+* previous suggestions for translation,
+* history of translation for this string,
+* a glossary if previously provided.
+
+WARNING: If the author of the translation is TM, the translation is a mere suggestion made by the Translation Memory and inserted by the team while waiting for further reviewing. In this case, be careful not to grant the reviewed status to such a string without really checking in the Valentina interface that the suggestion is allright.
+
+If the translation fits, click on 'Review', then a blue 'ok' icon appears on the reviewed string.
+
+image::string-pattern_properties-reviewed.png[]
+
+If the translation does not fit, enter the new text in the translation panel and click on 'save changes'. 
+
+If you are confident in the translation, review at the same time.
+
+A reviewed string can be modified by clicking on 'Unreview', enter new translation, save changes, and 'Review' again.
+
+<<<
+
+That's it ! You have translated and/or reviewed you first group of strings in context.
+
+Thanks a lot for your contribution to the Valentina project !

+# Introduction.
+
+This documentation describes the process for translating the GUI interface in Valentina.
+
+## Description.
+
+The project uses [Transifex](https://www.transifex.com/), a web platform allowing collaborative and centralized translation work.
+
+The translation project of the Valentina GUI interface is hosted [here](https://app.transifex.com/valentina/valentina-project/dashboard/).

+
+[[uploads/switch-transifex-gui-language.png|frame]]
+
+## Personal account settings.
+
+Click on the project icon at the bottom of the left sidebar to acess to your profile, there you can set up:
+
+* personal credentials,
+* notification settings, if you don't want to be notified absolutely every project or translation change,
+* sign in settings,

+
+> Note: Be aware that deactivationg comments notifications makes work harder and less efficient for the whole team.
+
+# Staff status in Transifex project.
+
+_In order to understand who referees are and their respectives roles + permissions_.
+
+## Administrator 
+
+Roman Telezhinkyi, id @dismine, Valentina main developer.
+
+## Coordinators
+
+23 presently.
+
+Coordinators manage each 1 or several translation teams.
+
+They have the specific permissions for accepting/ excluding members in Transifex.
+
+They are also translators and reviewers.
+
+## Reviewers
+
+Translators, but can also review translated strings.
+
+## Translators
+
+Can translate non reviewed strings.
+They can also make proposals if they see errors in préviously reviewed strings. 
+
+> **Note: Thus, if you have the translator status, don't try to review strings, please:**
+
+> **- Translate what has not been translated yet**
+
+> **- Comment previously translated and/or reviewed strings if you identify some translation error. Go to 'Comment' tab, tag in your comment @dismine (admin) and/or @your_coordinator_id, so they can be notified your comment and reply.**
+
+
+# Translating.
+
+## Accessing to the groups of ressources.
+
+On the project dashboard, hover over your language and click on "Translate" (the button text is provided in the language you set up for Transifex interface).
+
+You get access to a page displaying presently 2 groups of resources:
+
+1. "valentina.ts" for Valentina last 0.7.x version,
+2. "valentina_0.6.x.ts" for Valentina 0.6 version.
+
+You can also see how many strings have not been translated / reviewed yet in each group of resources.
+
+> Note: **By default, we translate in priority "valentina.ts" (the last software version) as it has the urgent priority tag.**
+
