-## User Guide for Local Directory Scanning and File Processing
-
-### 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/`.
-- Place any directories you want to be scanned into this folder. This folder should contain multiple folders, each for their own tasks and pipelines.
-
-### Configuring Processing with JSON Files
-
-- In each directory you want processed (e.g., `./pipeline/watchedFolders/officePrinter`), include a JSON configuration file.
-- This JSON file should specify how you want the files in the directory to be handled (e.g., what operations to perform on them). This can be made, configured, and downloaded from the Stirling-PDF Pipeline interface.
-
-### Automatic Scanning and Processing
-
-- The system automatically checks the watched folder every minute for new directories and files to process.
-- When a directory with a valid JSON configuration file is found, it begins processing the files inside according to the configuration.
-
-### Processing Steps
-
-- Files in each directory are processed according to the instructions in the JSON file.
-- This might involve file conversions, data filtering, renaming files, etc. If the output of a step is a zip, this zip will be automatically unzipped as it passes to the next process.
-
-### Results and Output
-
-- After processing, the results are saved in a specified output location. This could be a different folder or location as defined in the JSON file or the default location `./pipeline/finishedFolders/`.
-- Each processed file is named and organized according to the rules set in the JSON configuration.
-
-### Completion and Cleanup
-
-- Once processing is complete, the original files in the watched folder's directory are removed.
-- You can find the processed files in the designated output location.
-
-### Error Handling
-
-- If there's an error during processing, the system will not delete the original files, allowing you to check and retry if necessary.
-
-### User Interaction
-
-- As a user, your main tasks are to set up the watched folders, place directories with files for processing, and create the corresponding JSON configuration files.
-- The system handles the rest, including scanning, processing, and outputting results.

-To run the application without Docker/Podman, you will need to manually install all dependencies and build the necessary components.
-
-Note that some dependencies might not be available in the standard repositories of all Linux distributions, and may require additional steps to install.
-
-The following guide assumes you have a basic understanding of using a command line interface in your operating system.
-
-It should work on most Linux distributions and MacOS. For Windows, you might need to use Windows Subsystem for Linux (WSL) for certain steps. The amount of dependencies is to actually reduce overall size, i.e., installing LibreOffice subcomponents rather than the full LibreOffice package.
-
-You could theoretically use a Distrobox/Toolbox if your distribution has old or not all packages. But you might just as well use the Docker container then.
-
-### Step 1: Prerequisites
-
-Install the following software, if not already installed:
-
-- Java 17 or later (21 recommended)
-- Gradle 7.0 or later (included within the repo, so not needed on the server)
-- Git
-- Python 3.8 (with pip)
-- Make
-- GCC/G++
-- Automake
-- Autoconf
-- libtool
-- pkg-config
-- zlib1g-dev
-- libleptonica-dev
-
-For Debian-based systems, you can use the following command:
-
-```bash
-sudo apt-get update
-sudo apt-get install -y git automake autoconf libtool libleptonica-dev pkg-config zlib1g-dev make g++ openjdk-21-jdk python3 python3-pip
-```
-
-For Fedora-based systems, use this command:
-
-```bash
-sudo dnf install -y git automake autoconf libtool leptonica-devel pkg-config zlib-devel make gcc-c++ java-21-openjdk python3 python3-pip
-```
-
-For non-root users with Nix Package Manager, use the following command:
-
-```bash
-nix-channel --update
-nix-env -iA nixpkgs.jdk21 nixpkgs.git nixpkgs.python38 nixpkgs.gnumake nixpkgs.libgcc nixpkgs.automake nixpkgs.autoconf nixpkgs.libtool nixpkgs.pkg-config nixpkgs.zlib nixpkgs.leptonica
-```
-
-### Step 2: Clone and Build jbig2enc (Only required for certain OCR functionality)
-
-For Debian and Fedora, you can build it from source using the following commands:
-
-```bash
-mkdir ~/.git
-cd ~/.git && \
-git clone https://github.com/agl/jbig2enc.git && \
-cd jbig2enc && \
-./autogen.sh && \
-./configure && \
-make && \
-sudo make install
-```
-
-For Nix, you will face `Leptonica not detected`. Bypass this by installing it directly using the following command:
-
-```bash
-nix-env -iA nixpkgs.jbig2enc
-```
-
-### Step 3: Install Additional Software
-
-Next, we need to install LibreOffice for conversions, qpdf for OCR, and OpenCV for pattern recognition functionality.
-
-Install the following software:
-
-- libreoffice-core
-- libreoffice-common
-- libreoffice-writer
-- libreoffice-calc
-- libreoffice-impress
-- python3-uno
-- unoconv
-- pngquant
-- unpaper
-- qpdf
-- opencv-python-headless
-
-For Debian-based systems, you can use the following command:
-
-```bash
-sudo apt-get install -y libreoffice-writer libreoffice-calc libreoffice-impress unpaper qpdf
-pip3 install uno opencv-python-headless unoconv pngquant WeasyPrint --break-system-packages
-```
-
-For Fedora:
-
-```bash
-sudo dnf install -y libreoffice-writer libreoffice-calc libreoffice-impress unpaper qpdf
-pip3 install uno opencv-python-headless unoconv pngquant WeasyPrint
-```
-
-For Nix:
-
-```bash
-nix-env -iA nixpkgs.unpaper nixpkgs.libreoffice nixpkgs.qpdf nixpkgs.poppler_utils
-pip3 install uno opencv-python-headless unoconv pngquant WeasyPrint
-```
-
-### Step 4: Clone and Build Stirling-PDF
-
-```bash
-cd ~/.git && \
-git clone https://github.com/Stirling-Tools/Stirling-PDF.git && \
-cd Stirling-PDF && \
-chmod +x ./gradlew && \
-./gradlew build
-```
-
-### Step 5: Move Jar to Desired Location
-
-After the build process, a `.jar` file will be generated in the `build/libs` directory. You can move this file to a desired location, for example, `/opt/Stirling-PDF/`. You must also move the Script folder within the Stirling-PDF repo that you have downloaded to this directory. This folder is required for the Python scripts using OpenCV.
-
-```bash
-sudo mkdir /opt/Stirling-PDF && \
-sudo mv ./build/libs/Stirling-PDF-*.jar /opt/Stirling-PDF/ && \
-sudo mv scripts /opt/Stirling-PDF/ && \
-echo "Scripts installed."
-```
-
-For non-root users, you can just keep the jar in the main directory of Stirling-PDF using the following command:
-
-```bash
-mv ./build/libs/Stirling-PDF-*.jar ./Stirling-PDF-*.jar
-```
-
-### Step 6: Other Files
-
-#### OCR
-
-If you plan to use the OCR (Optical Character Recognition) functionality, you might need to install language packs for Tesseract if running non-English scanning.
-
-##### Installing Language Packs
-
-The easiest method is to use the language packs provided by your repositories. Skip the other steps if they are available.
-
-**Manual:**
-
-1. Download the desired language pack(s) by selecting the `.traineddata` file(s) for the language(s) you need.
-2. Place the `.traineddata` files in the Tesseract tessdata directory: `/usr/share/tessdata`
-
-**IMPORTANT:** DO NOT REMOVE EXISTING `eng.traineddata`, IT'S REQUIRED.
-
-**Debian-based systems**, install languages with this command:
-
-```bash
-sudo apt update && \
-# All languages
-# sudo apt install -y 'tesseract-ocr-*'
-
-# Find languages:
-apt search tesseract-ocr-
-
-# View installed languages:
-dpkg-query -W tesseract-ocr- | sed 's/tesseract-ocr-//g'
-```
-
-**Fedora:**
-
-```bash
-# All languages
-# sudo dnf install -y tesseract-langpack-*
-
-# Find languages:
-dnf search -C tesseract-langpack-
-
-# View installed languages:
-rpm -qa | grep tesseract-langpack | sed 's/tesseract-langpack-//g'
-```
-
-**Nix:**
-
-```bash
-nix-env -iA nixpkgs.tesseract
-```
-
-**Note:** Nix Package Manager pre-installs almost all the language packs when Tesseract is installed.
-
-### Step 7: Run Stirling-PDF
-
-Those who have pushed to the root directory, run the following commands:
-
-```bash
-./gradlew bootRun
-or
-java -jar /opt/Stirling-PDF/Stirling-PDF-*.jar
-```
-
-Since LibreOffice, soffice, and conversion tools have their dbus_tmp_dir set as `dbus_tmp_dir="/run/user/$(id -u)/libreoffice-dbus"`, you might get the following error when using their endpoints:
-
-```
-[Thread-7] INFO  s.s.SPDF.utils.ProcessExecutor - mkdir: cannot create directory ‘/run/user/1501’: Permission denied
-```
-
-To resolve this, before starting Stirling-PDF, you have to set the environment variable to a directory you have write access to by using the following commands:
-
-```bash
-mkdir temp
-export DBUS_SESSION_BUS_ADDRESS="unix:path=./temp"
-./gradlew bootRun
-or
-java -jar ./Stirling-PDF-*.jar
-```
-
-### Step 8: Adding a Desktop Icon
-
-This will add a modified app starter to your app menu.
-
-```bash
-location=$(pwd)/gradlew
-image=$(pwd)/docs/stirling-transparent.svg
-
-cat > ~/.local/share/applications/Stirling-PDF.desktop <<EOF
-[Desktop Entry]
-Name=Stirling PDF;
-GenericName=Launch StirlingPDF and open its WebGUI;
-Category=Office;
-Exec=xdg-open http://localhost:8080 && nohup $location bootRun &;
-Icon=$image;
-Keywords=pdf;
-Type=Application;
-NoDisplay=false;
-Terminal=true;
-EOF
-```
-
-Note: Currently, the app will run in the background until it is manually closed.
-
-### Optional: Changing the Host and Port of the Application
-
-To override the default configuration, you can add the following to `/.git/Stirling-PDF/configs/custom_settings.yml` file:
-
-```yaml
-server:
-  host: 0.0.0.0 # Not working - use instead address
-  address: 0.0.0.0
-  port: 3000
-```
-
-`-Djava.net.preferIPv4Stack=true` --> To force IPv4 only in the Java starting command
-
-**Note:** This file is created after the first application launch. To have it before that, you can create the directory and add the file yourself.
-
-### Optional: Run Stirling-PDF as a Service (requires root)
-
-First, create a `.env` file, where you can store environment variables:
-
-```bash
-touch /opt/Stirling-PDF/.env
-```
-
-In this file, you can add all variables, one variable per line, as stated in the main readme (for example `SYSTEM_DEFAULTLOCALE="de-DE"`).
-
-Create a new file where we store our service settings and open it with the nano editor:
-
-```bash
-nano /etc/systemd/system/stirlingpdf.service
-```
-
-Paste this content, and make sure to update the filename of the jar file. Press `Ctrl+S` and `Ctrl+X` to save and exit the nano editor:
-
-```ini
-[Unit]
-Description=Stirling-PDF service
-After=syslog.target network.target
-
-[Service]
-SuccessExitStatus=143
-
-User=root
-Group=root
-
-Type=simple
-
-EnvironmentFile=/opt/Stirling-PDF/.env
-WorkingDirectory=/opt/Stirling-PDF
-ExecStart=/usr/bin/java -jar Stirling-PDF-0.17.2.jar
-ExecStop=/bin/kill -15 $MAINPID
-
-[Install]
-WantedBy=multi-user.target
-```
-
-Notify systemd that it has to rebuild its internal service database (you have to run this command every time you make a change in the service file):
-
-```bash
-sudo systemctl daemon-reload
-```
-
-Enable the service to tell it to start automatically:
-
-```bash
-sudo systemctl enable stirlingpdf.service
-```
-
-See the status of the service:
-
-```bash
-sudo systemctl status stirlingpdf.service
-```
-
-Manually start/stop/restart the service:
-
-```bash
-sudo systemctl start stirlingpdf.service
-sudo systemctl stop stirlingpdf.service
-sudo systemctl restart stirlingpdf.service
-```
-
----
-
-Remember to set the necessary environment variables before running the project if you want to customize the application. The list can be seen in the main readme.
-
-You can do this in the terminal by using the `export` command or `-D` argument to the Java `-jar` command:
-
-```bash
-export APP_HOME_NAME="Stirling PDF"
-or
--DAPP_HOME_NAME="Stirling PDF"

-# Pipeline Configuration and Usage Tutorial
-
-- Configure the pipeline config file and input files to run files against it.
-- For reuse, download the config file and re-upload it when needed, or place it in `/pipeline/defaultWebUIConfigs/` to auto-load in the web UI for all users.
-
-## Steps to Configure and Use Your Pipeline
-
-1. **Access Configuration**
-   - Upon entering the screen, click on the **Configure** button.
-
-2. **Enter Pipeline Name**
-   - Provide a name for your pipeline in the designated field.
-
-3. **Select Operations**
-   - Choose the operations for your pipeline (e.g., **Split Pages**), then click **Add Operation**.
-
-4. **Configure Operation Settings**
-   - Input the necessary settings for each added operation. Settings are highlighted in yellow if customization is needed.
-
-5. **Add More Operations**
-   - You can add and adjust the order of multiple operations. Ensure each operation's settings are customized.
-
-6. **Save Settings**
-   - Click **Save Operation Settings** after customizing settings for each operation.
-
-7. **Validate Pipeline**
-   - Use the **Validation** button to check your pipeline. A green indicator signifies correct setup; a pop-out error indicates issues.
-
-8. **Download Pipeline Configuration**
-   - To use the configuration for folder scanning (or save it for future use and re-upload it), download a JSON file in this menu. You can also pre-load it for future use by placing it in `/pipeline/defaultWebUIConfigs/`. It will then appear in the dropdown menu for all users to use.
-
-9. **Submit Files for Processing**
-   - If your pipeline is correctly set up, close the configure menu, input the files, and hit **Submit**.
-
-10. **Note on Web UI Limitations**
-    - The current web UI version does not support operations that require multiple different types of inputs, such as adding a separate image to a PDF.
-
-### Current Limitations
-
-- Cannot have more than one of the same operation.
-- Cannot input additional files via UI.
-- All files and operations run in serial mode.

-## Customization
-
-Stirling-PDF allows easy customization of the app, including things like:
-
-- 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`, which is located in the `/configs` directory and follows standard YAML formatting, or using environment variables, which would override the settings file.
-
-For example, in `settings.yml`, you might have:
-
-```yaml
-security:
-  enableLogin: 'true'
-```
-
-To have this via an environment variable, you would use `SECURITY_ENABLELOGIN`.
-
-The current list of settings is:
-
-```yaml
-security:
-  enableLogin: false # set to 'true' to enable login
-  csrfDisabled: true # set to 'true' to disable CSRF protection (not recommended for production)
-  loginAttemptCount: 5 # lock user account after 5 tries; when using e.g. Fail2Ban you can deactivate the function with -1
-  loginResetTimeMinutes: 120 # lock account for 2 hours after x attempts
-  loginMethod: all # 'all' (Login Username/Password and OAuth2[must be enabled and configured]), 'normal'(only Login with Username/Password) or 'oauth2'(only Login with OAuth2)
-  initialLogin:
-    username: '' # initial username for the first login
-    password: '' # initial password for the first login
-  oauth2:
-    enabled: false # set to 'true' to enable login (Note: enableLogin must also be 'true' for this to work)
-    client:
-      keycloak:
-        issuer: '' # URL of the Keycloak realm's OpenID Connect Discovery endpoint
-        clientId: '' # client ID for Keycloak OAuth2

-        scopes: read:user # scope for GitHub OAuth2
-        useAsUsername: login # field to use as the username for GitHub OAuth2
-    issuer: '' # set to any provider that supports OpenID Connect Discovery (/.well-known/openid-configuration) endpoint
-    clientId: '' # client ID from your provider
-    clientSecret: '' # client secret from your provider
-    autoCreateUser: false # set to 'true' to allow auto-creation of non-existing users
-    blockRegistration: false # set to 'true' to deny login with SSO without prior registration by an admin
-    useAsUsername: email # default is 'email'; custom fields can be used as the username
-    scopes: openid, profile, email # specify the scopes for which the application will request permissions
-    provider: google # set this to your OAuth provider's name, e.g., 'google' or 'keycloak'
-  saml2:
-    enabled: false # currently in alpha, not recommended for use yet, enableAlphaFunctionality must be set to true
-    autoCreateUser: false # set to 'true' to allow auto-creation of non-existing users

-There is an additional config file `/configs/custom_settings.yml` where users familiar with Java and Spring `application.properties` can input their own settings on top of Stirling-PDF's existing ones.
-
-### Extra Notes
-
-- **Endpoints**: Currently, the `ENDPOINTS_TO_REMOVE` and `GROUPS_TO_REMOVE` endpoints can include comma-separated lists of endpoints and groups to disable. For example, `ENDPOINTS_TO_REMOVE=img-to-pdf,remove-pages` would disable both image-to-pdf and remove pages, while `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**: Customize static files such as the app logo by placing files in the `/customFiles/static/` directory. An example of customizing the app logo is placing `/customFiles/static/favicon.svg` to override the current SVG. This can be used to change any `images/icons/css/fonts/js`, etc. in Stirling-PDF.
-
-### Environment-Only Parameters
-
-- `SYSTEM_ROOTURIPATH` - Set the application's root URI (e.g. `/pdf-app` to set the root URI to `localhost:8080/pdf-app`)
-- `SYSTEM_CONNECTIONTIMEOUTMINUTES` - Set custom connection timeout values
-- `DOCKER_ENABLE_SECURITY` - Set to `true` to download security jar (required for authentication login)
-- `INSTALL_BOOK_AND_ADVANCED_HTML_OPS` - Download Calibre onto Stirling-PDF to enable PDF to/from book and advanced HTML conversion
-- `LANGS` - Define custom font libraries to install for document conversions
-
-## API
-
-For those wanting to use Stirling-PDF's 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 version's documentation (or by following the API button in the settings of Stirling-PDF).
-
-## Login Authentication
-
-![stirling-login](images/login-light.png)
-
-### Prerequisites
-
-- User must have the folder `./configs` volumed within Docker so that it is retained during updates.
-- 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 set `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 credentials straight away (recommended to remove them after user creation).
-
-Once the above has been done, on restart, a new `stirling-pdf-DB.mv.db` will show if everything worked.
-
-When you log in to Stirling-PDF, you will be redirected to the `/login` page to log in with those default credentials. After login, everything should function as normal.
-
-To access your account settings, go to Account Settings in the settings cog menu (top right in the navbar). This Account Settings menu is also where you find your API key.
-
-To add new users, go to the bottom of Account Settings and hit 'Admin Settings'. Here, you can add new users. The different roles mentioned within this are for rate limiting. This is a work in progress and will be expanded on more in the future.
-
-For API usage, you must provide a header with `X-API-KEY` and the associated API key for that user.
-
-## 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)
-- Add forms
-- Multi-page layout (stitch PDF pages together) support x rows y columns and custom page sizing
-- Fill forms manually or automatically
-
-### Q2: Why is my application downloading .htm files? Why am I getting HTTP error 413?
-
-This is an issue commonly caused 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;`.
