+### Hard Recovery Guide
+
+If you still have the source files in the media dir folder, 
+but you forgot to make a backup according to the instructions in the main readme - you can perform a hard recovery process.
+
+##### DISCLAIMER 1) ALL OPERATIONS AND HARM FROM THIS SCRIPT - YOUR OWN RESPONSIBILITY!
+##### DISCLAIMER 2) USE THIS SCRIPT ONLY IF THERE AREN`T ANOTHER WAY!
+
+### Preparation steps
+You need to have a setup WebODM admin account before starting recovery.
+If you already create admin account - skip this step.
+
+## Step 0. Enter the `manage.py` shell of webODM for HARD RECOVERY
+From inside the webodm_webapp container:
+List the container of WebODM with usage of `docker ps` command, or using Docker Desktop.
+Connect into the webodm container using:
+```
+docker exec -ti webodm_webapp bash
+python manage.py shell
+```
+
+
+## Step 1. Copy and paste imports and functions to py shell
+
+```python

+                print(f"Succesfully indexed file {image_shot['filename']}")
+    except Exception as e:
+        print(e)
+
+# END COPY FIRST PART
+```
+## Step 2. Specify the username of admin which will have acess to the imported projects
+```python
+# START COPY SECOND PART
+user = User.objects.get(username="YOUR NEW CREATED ADMIN USERNAME HERE")
+# END COPY COPY SECOND PART
+```
+
+## Step 3. This is the main part of script which make the main magic of the project. It will read media dir and create tasks and projects from the sources, also it will reindex photo sources, if avaliable
+```python
+# START COPY THIRD PART
+for project_id in os.listdir("/webodm/app/media/project"):
+    if not Project.objects.filter(id=int(project_id)).exists():
+        project = create_project(project_id, user)
+        project.save()
+    else:
+        project = Project.objects.get(pk=(project_id))
+    for task_id in os.listdir(f"/webodm/app/media/project/{project_id}/task"):
+        if not Task.objects.filter(id=task_id).exists():
+            task = Task(project=project)
+            task.id = task_id
+            process_task(task)
+            reindex_shots(project_id, task_id)
+# END COPY THIRD PART
+```
+## Step 4. You must update project ID sequence for new created tasks
+```python
+with connection.cursor() as cursor:
+                cursor.execute("SELECT setval('app_project_id_seq', (SELECT MAX(id) FROM app_project)+1)")
+```
+If all is ok - you will get recreated structure of projects inside WebODM database, and WebODM GUI.
+Congratulations - you are great!
