+# Replacing Sphinx Search with Nuclia Search in Plone
+
+## Overview
+
+This documentation outlines the process of replacing Sphinx search in a Plone site with Nuclia search. The goal is to explain the approach taken and provide instructions for replicating the process in another project.
+
+## Approach
+
+To achieve the transition from Sphinx to Nuclia search, we took an approach as shown in the following generalized outline.
+
+1. Generate Nuclia sync data
+
+    -   Iterate through `.md` files in the repository [docs](https://github.com/plone/documentation/tree/6.0/docs) .
+    -   Calculate the hash of each file and store the mapping in `nuclia_sync.json`.
+
+2. Extract Headings
+
+    -   Use regular expressions to extract headings from Markdown files.
+    -   Store the extracted headings and slugs for document URLs.
+
+3. Upload Documents
+
+    -   Utilize the `NucliaUpload` class from the `nuclia` SDK.
+    -   Generated slugs, Extracted headings, Nuclia `API_KEY` and constructed URLs for `.md` can be passed in the class method.
+
+4. Synchronize Documents
+
+    -   Compare hashes to determine whether to upload, update, or delete documents, when changes are made.
+    -   Handle document deletions using the `NucliaKB` class.
+
+5. GitHub Actions Workflow
+
+    -   Created a synchronization workflow triggered by a `push` event.
+    -   Defined the steps for checking out code, setting up the Python environment, running the sync script, and committing changes back to the repository.
+
+## Replication steps
+
+Follow these steps to replicate the process in your own project:
+
+### Pre-requisites
+
+-   See [installation](https://6.docs.plone.org/install/index.html) for requirements to build Plone 6 Documentation.
+-   See `Training <inv:training:std:lable:installation>` for requirements to build Plone Training.
+
+### Global configuration for `upload.py`
+
+1.  `PUBLIC_URL`
+    -   Set the URL of your website.
+
+2.  `API Key`
+    -   Set this variable with the API key of your knowledge box.
+
+3.  `KB`
+    -   Set up this variable with your knowledge box URL.
+
+### Indexing and syncing
+
+1.  Generate Sync Document
+
+    -   Make sure to create a `json` file and replace each path of `json` file being read or written inside `upload` script with the path of your `json` file.
+    -   Fill the `json` with content as given below this is essential for syncing old and new data.
+
+        ```json
+        {
+            "docs" : {
+
+            }
+        }
+        ```
+
+2.  Populate Sync Document
+
+    -   Running the `upload` script will now eventually handle the syncing and indexing to the knowledge box.    
+
+     ```bash
+     python3 upload.py
+     ```
+
+### Integrating the widget
+
+-   Nuclia provides with it's own widget code for our use. 
+
+-   Choose the functionalities you want your widget to have from the widget generator tab. 
+
+-   You will be provided with a code snippet from nuclia which can be used for integration.
+
+-   To perform style changes to the widget you may have to use CSS or other alternatives.
+
+### GitHub Actions
+
+Modify the GitHub Actions workflow `nuclia_sync.yml` to match your repository structure.
+
+## Usage notes
+
+-   Ensure that the API key and knowledge box URL are correctly configured.
+-   Troubleshoot issues by checking the API key validity and document URLs.
+
+## Conclusion
+
+Replacing Sphinx search with Nuclia search brings improved search functionality to Plone sites.
+Feel free to reach out for assistance or clarification on any aspect of this documentation.
+Happy syncing and searching!
