+
+To run the application without Docker, 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, ie installing LibreOffice sub components rather than full LibreOffice package.
+
+### Step 1: Prerequisites
+
+Install the following software, if not already installed:
+
+- Java 17 or later
+
+- Gradle 7.0 or later (included within repo so not needed on server)
+
+- Git
+
+- Python 3 (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++ java-17-openjdk python3 python3-pip
+```
+
+### Step 2: Clone and Build jbig2enc (Only required for certain OCR functionality)
+
+```bash
+git clone https:github.com/agl/jbig2enc
+cd jbig2enc
+./autogen.sh
+./configure
+make
+sudo make install
+```
+
+### Step 3: Install Additional Software
+Next we need to install LibreOffice for conversions, ocrmypdf for OCR, and opencv for patern recognition functionality.
+
+Install the following software:
+
+- libreoffice-core
+
+- libreoffice-common
+
+- libreoffice-writer
+
+- libreoffice-calc
+
+- libreoffice-impress
+
+- python3-uno
+
+- unoconv
+
+- pngquant
+
+- unpaper
+
+- ocrmypdf
+
+- opencv-python-headless
+
+For Debian-based systems, you can use the following command:
+
+```bash
+sudo apt-get install -y libreoffice-core libreoffice-common libreoffice-writer libreoffice-calc  libreoffice-impress python3-uno  unoconv  pngquant  unpaper  ocrmypdf
+pip3 install opencv-python-headless
+```
+
+### Step 4: Clone and Build Stirling-PDF
+
+```bash
+git clone https://github.com/Frooodle/Stirling-PDF.git
+cd Stirling-PDF
+./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
+
+### 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 none english scanning.
+
+##### Installing Language Packs
+
+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/tesseract-ocr/4.00/tessdata`
+Please view  [OCRmyPDF install guide](https://ocrmypdf.readthedocs.io/en/latest/installation.html) for more info.
+**IMPORTANT:** DO NOT REMOVE EXISTING `eng.traineddata`, IT'S REQUIRED.
+
+
+
+### Step 7: Run Stirling-PDF
+
+```bash
+./gradlew bootRun
+or
+java -jar build/libs/app.jar
+```
+
+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 arguements to java -jar command:
+
+```bash
+export APP_HOME_NAME="Stirling PDF"
+or
+-DAPP_HOME_NAME="Stirling PDF" 
+```
+
