+
+Thank you for your interest in contributing to Stirling-PDF! There are many ways to contribute other than writing code. For example, reporting bugs, creating suggestions, and adding or modifying translations.
+
+## Issue Guidelines
+
+Issues can be used to report bugs, request features, or ask questions. If you have a question, you could also ask us in our [Discord](https://discord.gg/FJUSXUSYec).
+
+Before opening an issue, please check to make sure someone hasn't already opened an issue about it.
+
+## Pull Requests
+
+Before you start working on an issue, please comment on (or create) the issue and wait for it to be assigned to you. If someone has already been assigned but didn't have the time to work on it lately, please communicate with them and ask if they're still working on it. This is to avoid multiple people working on the same issue.
+
+Once you have been assigned an issue, you can start working on it. When you are ready to submit your changes, open a pull request.
+For a detailed pull request tutorial, see [this guide](https://www.digitalocean.com/community/tutorials/how-to-create-a-pull-request-on-github).
+
+Please make sure your Pull Request adheres to the following guidelines:
+
+- Use the PR template provided.

+- References to the Issue number in the Pull Request and/or Commit message.
+
+## Translations
+
+If you would like to add or modify a translation, please see [How to add new languages to Stirling-PDF](HowToAddNewLanguage.md). Also, please create a Pull Request so others can use it!
+
+## Fixing Bugs or Adding a New Feature
+
+First, make sure you've read the section [Pull Requests](#pull-requests).

+## User Guide for Local Directory Scanning and File Processing
+
+### Whilst Pipelines are in alpha...
+You must enable this alpha functionality by setting
+```yaml
+system:
+  enableAlphaFunctionality: true
+```
+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/`
+- 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) which can be made, configured and downloaded from Stirling-PDF Pipeline interface.r
+
+### 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 as per 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 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.

+# Pipeline Configuration and Usage Tutorial
+
+## Whilst Pipelines are in alpha...
+You must enable this alpha functionality by setting
+```yaml
+system:
+  enableAlphaFunctionality: true
+```
+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.
+
+
+## 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 reupload it), you can also download a JSON file in this menu. You can also pre-load this 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.

 ### 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.
