 # Important Note

 Document scanners are typically used to scan sensitive documents.  Things like your social insurance number, tax records, invoices, etc.  Everything is stored in the clear without encryption. This means that Paperless should never be run on an untrusted host.  Instead, I recommend that if you do want to use it, run it locally on a server in your own home.

+API Versioning
+##############
+
+The REST API is versioned since Paperless-ng 1.3.0.
+
+* Versioning ensures that changes to the API don't break older clients.
+* Clients specify the specific version of the API they wish to use with every request and Paperless will handle the request using the specified API version.
+* Even if the underlying data model changes, older API versions will always serve compatible data.
+* If no version is specified, Paperless will serve version 1 to ensure compatibility with older clients that do not request a specific API version.
+
+API versions are specified by submitting an additional HTTP ``Accept`` header with every request:
+
+.. code::
+
+    Accept: application/json; version=6
+
+If an invalid version is specified, Paperless 1.3.0 will respond with "406 Not Acceptable" and an error message in the body.
+Earlier versions of Paperless will serve API version 1 regardless of whether a version is specified via the ``Accept`` header.
+
+If a client wishes to verify whether it is compatible with any given server, the following procedure should be performed:
+
+1.  Perform an *authenticated* request against any API endpoint. If the server is on version 1.3.0 or newer, the server will
+    add two custom headers to the response:
+
+    .. code::
+
+        X-Api-Version: 2
+        X-Version: 1.3.0
+
+2.  Determine whether the client is compatible with this server based on the presence/absence of these headers and their values if present.

+
+Initial setup and first start 
+=============================
+
+After you forked and cloned the code from github you need to perform a first-time setup. 
+To do the setup you need to perform the steps from the following chapters in a certain order:
+
+1.  Install prerequisites + pipenv as mentioned in :ref:`Bare metal route <setup-bare_metal>`
+2.  Copy ``paperless.conf.example`` to ``paperless.conf`` and enable debug mode.
+3.  Install the Angular CLI interface:
+
+    .. code:: shell-session
+
+        $ npm install -g @angular/cli 
+
+4.  Create ``consume`` and ``media`` folders in the cloned root folder.
+   
+    .. code:: shell-session
+
+        mkdir -p consume media
+
+5.  You can now either ...
+
+    *  install redis or 
+    *  use the included scripts/start-services.sh to use docker to fire up a redis instance (and some other services such as tika, gotenberg and a postgresql server) or
+    *  spin up a bare redis container 
+
+        .. code:: shell-session
+
+            docker run -d -p 6379:6379 -restart unless-stopped redis:latest
+
+6.  Install the python dependencies by performing in the src/ directory.
+
+    .. code:: shell-session
+
+        pipenv install --dev
+
+7.  Generate the static UI so you can perform a login to get session that is required for frontend development (this needs to be done one time only). From root folder:
+
+    .. code:: shell-session
+
+        compile-frontend.sh
+
+8.  Apply migrations and create a superuser for your dev instance:
+
+    .. code:: shell-session
+
+        python3 manage.py migrate
+        python3 manage.py createsuperuser
+
+9.  Now spin up the dev backend. Depending on which part of paperless you're developing for, you need to have some or all of them running.
+
+    .. code:: shell-session
+
+        python3 manage.py runserver & python3 manage.py document_consumer & python3 manage.py qcluster
+
+10. Login with the superuser credentials provided in step 8 at ``http://localhost:8000`` to create a session that enables you to use the backend.
+

+Localization
+============
+
+Paperless is available in many different languages. Since paperless consists both of a django
+application and an Angular front end, both these parts have to be translated separately.
+
+Front end localization
+----------------------
+
+*   The Angular front end does localization according to the `Angular documentation <https://angular.io/guide/i18n>`_.
+*   The source language of the project is "en_US".
+*   The source strings end up in the file "src-ui/messages.xlf".
+*   The translated strings need to be placed in the "src-ui/src/locale/" folder.
+*   In order to extract added or changed strings from the source files, call ``ng xi18n --ivy``.
+
+Adding new languages requires adding the translated files in the "src-ui/src/locale/" folder and adjusting a couple files.
+
+1.  Adjust "src-ui/angular.json":
+
+    .. code:: json
+
+        "i18n": {
+            "sourceLocale": "en-US",
+            "locales": {
+                "de": "src/locale/messages.de.xlf",
+                "nl-NL": "src/locale/messages.nl_NL.xlf",
+                "fr": "src/locale/messages.fr.xlf",
+                "en-GB": "src/locale/messages.en_GB.xlf",
+                "pt-BR": "src/locale/messages.pt_BR.xlf",
+                "language-code": "language-file"
+            }
+        }
+
+2.  Add the language to the available options in "src-ui/src/app/services/settings.service.ts":
+
+    .. code:: typescript
+
+        getLanguageOptions(): LanguageOption[] {
+            return [
+                {code: "en-us", name: $localize`English (US)`, englishName: "English (US)", dateInputFormat: "mm/dd/yyyy"},
+                {code: "en-gb", name: $localize`English (GB)`, englishName: "English (GB)", dateInputFormat: "dd/mm/yyyy"},
+                {code: "de", name: $localize`German`, englishName: "German", dateInputFormat: "dd.mm.yyyy"},
+                {code: "nl", name: $localize`Dutch`, englishName: "Dutch", dateInputFormat: "dd-mm-yyyy"},
+                {code: "fr", name: $localize`French`, englishName: "French", dateInputFormat: "dd/mm/yyyy"},
+                {code: "pt-br", name: $localize`Portuguese (Brazil)`, englishName: "Portuguese (Brazil)", dateInputFormat: "dd/mm/yyyy"}
+                // Add your new language here
+            ]
+        }
+    
+    ``dateInputFormat`` is a special string that defines the behavior of the date input fields and absolutely needs to contain "dd", "mm" and "yyyy".
+
+3.  Import and register the Angular data for this locale in "src-ui/src/app/app.module.ts":
+
+    .. code:: typescript
+
+        import localeDe from '@angular/common/locales/de';
+        registerLocaleData(localeDe)
+
+Back end localization
+---------------------
+
+A majority of the strings that appear in the back end appear only when the admin is used. However,
+some of these are still shown on the front end (such as error messages).
+
+*   The django application does localization according to the `django documentation <https://docs.djangoproject.com/en/3.1/topics/i18n/translation/>`_.
+*   The source language of the project is "en_US".
+*   Localization files end up in the folder "src/locale/".
+*   In order to extract strings from the application, call ``python3 manage.py makemessages -l en_US``. This is important after making changes to translatable strings.
+*   The message files need to be compiled for them to show up in the application. Call ``python3 manage.py compilemessages`` to do this. The generated files don't get
+    committed into git, since these are derived artifacts. The build pipeline takes care of executing this command.
+
+Adding new languages requires adding the translated files in the "src/locale/" folder and adjusting the file "src/paperless/settings.py" to include the new language:
+
+.. code:: python
+
+    LANGUAGES = [
+        ("en-us", _("English (US)")),
+        ("en-gb", _("English (GB)")),
+        ("de", _("German")),
+        ("nl-nl", _("Dutch")),
+        ("fr", _("French")),
+        ("pt-br", _("Portuguese (Brazil)")),
