-system:

-To true like in the above for your `/config/settings.yml` file, after restarting Stirling-PDF you should see both UI and folder scanning enabled.

 ### Setting Up Watched Folders:
 - Create a folder where you want your files to be monitored. This is your 'watched folder'.
 - The default directory for this is `./pipeline/watchedFolders/`

+## Handling Untranslatable Strings
 
+Sometimes, certain strings in the properties file may not require translation because they are the same in the target language or are universal (like names of protocols, certain terminologies, etc.). To ensure accurate statistics for language progress, these strings should be added to the `ignore_translation.toml` file located in the `scripts` directory. This will exclude them from the translation progress calculations.
 
+For example, if the English string error=Error does not need translation in Polish, add it to the ignore_translation.toml under the Polish section:
+
+```toml
+[pl_PL]
+ignore = [
+    "language.direction",  # Existing entries
+    "error"                # Add new entries here
+]
+```
+
+Make sure to place the entry under the correct language section. This helps maintain the accuracy of translation progress statistics and ensures that the translation tool or scripts do not misinterpret the completion rate.

 ## Customisation

 Stirling PDF allows easy customization of the app.
 Includes things like
-- Custom application name
-- Custom slogans, icons, images, and even custom HTML (via file overrides)
 
+- Custom application name
+- Custom slogans, icons, HTML, images CSS etc (via file overrides) 
 
 There are two options for this, either using the generated settings file ``settings.yml``

+There is an additional config file ``/configs/custom_settings.yml`` were users familiar with java and spring application.properties can input their own settings on-top of Stirling-PDFs existing ones
+
 ### Extra notes
+
 - Endpoints. Currently, the endpoints ENDPOINTS_TO_REMOVE and GROUPS_TO_REMOVE can include comma separate lists of endpoints and groups to disable as example ENDPOINTS_TO_REMOVE=img-to-pdf,remove-pages would disable both image-to-pdf and remove pages, GROUPS_TO_REMOVE=LibreOffice Would disable all things that use LibreOffice. You can see a list of all endpoints and groups [here](https://github.com/Stirling-Tools/Stirling-PDF/blob/main/Endpoint-groups.md)
 - customStaticFilePath. Customise static files such as the app logo by placing files in the /customFiles/static/ directory. An example of customising app logo is placing a /customFiles/static/favicon.svg to override current SVG. This can be used to change any images/icons/css/fonts/js etc in Stirling-PDF
 
 ### Environment only parameters
+
 - ``SYSTEM_ROOTURIPATH`` ie set to ``/pdf-app`` to Set the application's root URI to ``localhost:8080/pdf-app``
 - ``SYSTEM_CONNECTIONTIMEOUTMINUTES`` to set custom connection timeout values
 - ``DOCKER_ENABLE_SECURITY`` to tell docker to download security jar (required as true for auth login)
+- ``INSTALL_BOOK_AND_ADVANCED_HTML_OPS`` to download calibre onto stirling-pdf enabling pdf to/from book and advanced html conversion
+- ``LANGS`` to define custom font libraries to install for use for document conversions
 
 ## API
+
 For those wanting to use Stirling-PDFs backend API to link with their own custom scripting to edit PDFs you can view all existing API documentation
 [here](https://app.swaggerhub.com/apis-docs/Stirling-Tools/Stirling-PDF/) or navigate to /swagger-ui/index.html of your stirling-pdf instance for your versions documentation (Or by following the API button in your settings of Stirling-PDF)

 ## Login authentication

 ### Prerequisites:
+
 - User must have the folder ./configs volumed within docker so that it is retained during updates.
-- Docker uses must download the security jar version by setting ``DOCKER_ENABLE_SECURITY`` to ``true`` in environment variables.
+- Docker users must download the security jar version by setting ``DOCKER_ENABLE_SECURITY`` to ``true`` in environment variables.
 - Then either enable login via the settings.yml file or via setting ``SECURITY_ENABLE_LOGIN`` to ``true``
 - Now the initial user will be generated with username ``admin`` and password ``stirling``. On login you will be forced to change the password to a new one. You can also use the environment variables ``SECURITY_INITIALLOGIN_USERNAME`` and  ``SECURITY_INITIALLOGIN_PASSWORD`` to set your own straight away (Recommended to remove them after user creation).

 ## FAQ
 
 ### Q1: What are your planned features?
+
 - Progress bar/Tracking
 - Full custom logic pipelines to combine multiple operations together.
 - Folder support with auto scanning to perform operations on
 - Redact text (Via UI not just automated way)
 - Add Forms
 - Multi page layout (Stich PDF pages together) support x rows y columns and custom page sizing
-- Fill forms mannual and automatic
+- Fill forms manually or automatically
 
 ### Q2: Why is my application downloading .htm files?
+
 This is an issue caused commonly by your NGINX configuration. The default file upload size for NGINX is 1MB, you need to add the following in your Nginx sites-available file. ``client_max_body_size SIZE;`` Where "SIZE" is 50M for example for 50MB files.
 
 ### Q3: Why is my download timing out
+
 NGINX has timeout values by default so if you are running Stirling-PDF behind NGINX you may need to set a timeout value such as adding the config ``proxy_read_timeout 3600;``
