+# C1 - MongoDB Connectivity
+
+**Problem Statement:** Write a program to implement MongoDB database connectivity with PHP /python /Java Implement Database navigation CRUD operations (add, delete, edit etc.)
+
+---
+
+## Pre-requisites (with installation command for Ubuntu):
+1. Python3 - `sudo apt install python3`
+2. pip - `sudo apt install python3-pip`
+3. pymongo -  `pip3 install pymongo` OR `pip3 install pymongo --break-system-packages` (installs it system-wide)
+
+## Instructions
+
+1. First, open the Terminal and log in to MongoDB:
+```shell
+mongo
+
+```
+
+2. Now, in Mongo we need to initialize the database and tables:
+```json
+// Create database
+use connectMe;
+// Create collection
+db.createCollection("students");
+// exit
+exit
+
+```
+
+> We need to `exit` from Mongo shell since the work there is done for now.
+
+3. Create a new file `connectMongo.py` with the following contents:
+```python
+from pymongo import MongoClient
+
+client = MongoClient("mongodb://127.0.0.1:27017")
+database = client.connectMe
+collection = database.students
+
+collection.insert_one({"roll":"21", "name":"Stewie"}) # insert operation
+print("Inserted")
+collection.insert_one({"roll":"22", "name":"Foxy"}) # insert operation
+print("Inserted")
+collection.update_one({"roll": "21"}, {"$set": {"roll": "20"}}) # update operation
+print("Updated")
+collection.delete_one({"roll": "22"})
+print("Deleted")
+
+client.close()
+
+```
+
+4. Open Terminal and run the above program:
+```shell
+python3 connectMongo.py
+```
+
+> [!NOTE]
+> This step assume you have stored the file in home directory or you know how to change the current working directory.
+
+5. That's it! You can view the changes in Mongo by logging in using `mongo` and viewing the table:
+```json
+USE connectMe;
+db.students.find();
+
+```
+
+> [!Tip]
+> This guide assumes your `mongo` shell does not have any password for root user.
+
+> [!WARNING]
+> Never use `root` as password in production. Use a strong password. This guide uses `root` as password for simplicity and educational purposes.
