+      <p>
+        My research investigates the intersection of mycelium and emancipatory
+        technologies. I am interested in the potential of new convivial tooling
+        as a medium for group consensus building and collective action, in order
+        to empower communities of practice to address their own challenges.
+      </p>
+
+      <p>
+        My current focus is basic research into the nature of digital
+        organisation, developing prototype toolkits to improve shared
+        infrastructure, and applying this research to the design of new systems
+        and protocols which support the self-organisation of knowledge and
+        emergent response to local needs.
+      </p>

+
+Yes, it is possible to allow users of your website to render their own Google Docs securely, but it requires additional steps to ensure privacy, user authentication, and proper permissions. Here's how you can set it up:
+
+---
+
+### Steps to Enable Users to Render Their Own Google Docs
+
+#### 1. Enable Google Sign-In for Your Website
+   - Users need to authenticate with their Google account to grant your app access to their documents.
+   - Use the [Google Sign-In library](https://developers.google.com/identity/sign-in/web) to implement OAuth authentication.
+
+   Steps:
+   - Include the Google Sign-In button on your site:
+          <script src="https://apis.google.com/js/platform.js" async defer></script>
+     <meta name="google-signin-client_id" content="YOUR_CLIENT_ID.apps.googleusercontent.com">
+     <div class="g-signin2" data-onsuccess="onSignIn"></div>
+     
+
+   - Handle the user's authentication token on sign-in:
+          function onSignIn(googleUser) {
+         var profile = googleUser.getBasicProfile();
+         var idToken = googleUser.getAuthResponse().id_token;
+
+         // Send the token to your backend to authenticate and fetch user-specific documents
+         fetch('/api/authenticate', {
+             method: 'POST',
+             headers: { 'Content-Type': 'application/json' },
+             body: JSON.stringify({ token: idToken }),
+         }).then(response => response.json())
+           .then(data => console.log(data));
+     }
+     
+
+---
+
+#### 2. Request Google Docs API Permissions
+   - Once the user is authenticated, request permissions for the Google Docs API.
+   - Scopes needed:
+     
+     https://www.googleapis.com/auth/documents.readonly
+     
+
+   - Example request for API access:
+          function requestDocsAccess() {
+         gapi.auth2.getAuthInstance().signIn({
+             scope: 'https://www.googleapis.com/auth/documents.readonly',
+         }).then(() => {
+             console.log('API access granted');
+         });
+     }
+     
+
+---
+
+#### 3. Fetch User's Document Content
+   - After receiving user authorization, fetch their document content using the Google Docs API.
+   - Example using JavaScript:
+          gapi.client.load('docs', 'v1', function () {
+         var request = gapi.client.docs.documents.get({
+             documentId: 'USER_DOCUMENT_ID',
+         });
+
+         request.execute(function (response) {
+             console.log(response);
+             // Render document content on your website
+             document.getElementById('doc-container').innerHTML = response.body.content.map(
+                 item => item.paragraph.elements.map(
+                     el => el.textRun.content
+                 ).join('')
+             ).join('<br>');
+         });
+     });
+     
+
+   - Ensure that USER_DOCUMENT_ID is input by the user (e.g., through a form field).
+
+---
+
+#### 4. Secure Your Backend
+   - Create an API endpoint to handle requests for fetching document content.
+   - Validate the user's Google token on your server using Google's token verification endpoint.
+   - Use their authenticated token to call the Google Docs API and fetch the requested document.
+
+   Example in Python (using Flask):
+      from google.oauth2 import id_token
+   from google.auth.transport import requests
+   from googleapiclient.discovery import build
+
+   @app.route('/api/fetch-doc', methods=['POST'])
+   def fetch_doc():
+       token = request.json.get('token')
+       document_id = request.json.get('document_id')
+
+       # Verify token
+       idinfo = id_token.verify_oauth2_token(token, requests.Request(), CLIENT_ID)
+       if idinfo['iss'] not in ['accounts.google.com', 'https://accounts.google.com']:
+           return 'Invalid token', 401
+
+       # Fetch the document
+       creds = id_token.Credentials(token=token)
+       service = build('docs', 'v1', credentials=creds)
+       doc = service.documents().get(documentId=document_id).execute()
+
+       return jsonify(doc)
+       
+   
+
+---
+
+rohan mehta, [2024-11-21 4:42 PM]
+#### 5. Provide a Frontend UI
+   - Allow users to input their Google Doc ID through a form.
+   - Example:
+          <input type="text" id="doc-id" placeholder="Enter your Google Doc ID">
+     <button onclick="fetchDoc()">Render Doc</button>
+     <div id="doc-container"></div>
+     
+
+   - JavaScript to send the document ID to your backend:
+          function fetchDoc() {
+         const docId = document.getElementById('doc-id').value;
+
+         fetch('/api/fetch-doc', {
+             method: 'POST',
+             headers: { 'Content-Type': 'application/json' },
+             body: JSON.stringify({ token: userToken, document_id: docId }),
+         })
+         .then(response => response.json())
+         .then(data => {
+             document.getElementById('doc-container').innerHTML = JSON.stringify(data);
+         });
+     }
+     
+
+---
+
+### Security and Privacy Considerations
+1. Authentication:
+   - Verify each user's Google token before processing their request.
+   - Only fetch documents they own or have shared with them.
+
+2. Rate Limiting:
+   - Implement rate limiting on your backend API to prevent abuse.
+
+3. Permission Scope:
+   - Use the minimal scope (documents.readonly) to ensure you can only read documents, not modify them.
+
+4. Data Handling:
+   - Never store user document content unless explicitly required and with user consent.
+
+---
+
+With this approach, each user will be able to render their own Google Docs securely while maintaining privacy. Let me know if you’d like a more detailed implementation in any specific programming language!
