+# Monk & MongoDB
+
+This repository contains Monk.io template to deploy MongoDB cluster in system either locally or on cloud of your choice (AWS, GCP, Azure, Digital Ocean).
+
+## Start
+
+[Set up Monk](https://docs.monk.io/docs/monk-in-10/)
+
+Start `monkd` and login.
+
+```bash
+monk login --email=<email> --password=<password>
+```
+
+## Clone Monk MongoDB repository
+
+In order to load templates and change configuration simply use below commands:
+
+```bash
+git clone https://github.com/monk-io/monk-mongodb
+
+# and change directory to the monk-elk template folder
+cd monk-mongodb/mongodb-replicated
+
+```
+
+## Configuration
+
+You can add/remove configuration of the template.
+
+The current variables can be found in `mongodb/variables` section
+
+```yaml
+  variables:
+    mongo-image-tag: "latest"
+    mongodb-init-username: "mongo"
+    mongodb-init-password: "password"
+    mongodb-init-database: "mongo"
+```
+
+## Template variables
+
+| Variable                  | Description                    | Type   | Default  |
+| ------------------------- | ------------------------------ | ------ | -------- |
+| **mongo-image-tag**       | MongoDB image version.         | string | latest   |
+| **mongodb-init-username** | MongoDB Initial root username. | string | mongo    |
+| **mongodb-init-password** | MongoDB Initial root password. | string | password |
+| **mongodb-init-database** | MongoDB Initial root database. | string | mongo    |
+
+## Local Deployment
+
+| First clone the repository simply run below command after launching `monkd`: |
+| :--------------------------------------------------------------------------: |
+
+```bash
+➜  monk load MANIFEST
+
+✨ Loaded:
+ ├─🔩 Runnables:
+ │  ├─🧩 mongodb-replicated/mongodb-common
+ │  ├─🧩 mongodb-replicated/mongodb-1

+group     mongodb-replicated/stack            local       -        -
+
+
+➜ monk run mongodb-replicated/stack
+
+✔ Started local/mongodb-replicated/stack
+
+```
+
+This will start the entire mongodb-replicated/stack.
+
+## Cloud Deployment
+
+To deploy the above system to your cloud provider, create a new Monk cluster and provision your instances.
+
+```bash
+➜  monk cluster new -n monkha
+✔ Cluster created
+Your cluster has been created successfully.
+
+➜  monk cluster provider add -p aws -f <path/to/your-credentials-file>
+✔ Provider added successfully
+
+➜   monk cluster grow -p  aws --name monkha --tag monkha  -i t3.large --region eu-north-1 -m 3 -d 50 --disk-type SSD
+✔ Start creation of new instance(s) on aws... DONE
+✔ Creating node: monkha-1 DONE
+✔ Creating node: monkha-2 DONE
+✔ Initializing node: monkha-1 DONE
+✔ Initializing node: monkha-2 DONE
+✔ Creating node: monkha-3 DONE
+✔ Initializing node: monkha-3 DONE
+✔ Connecting: monkha-1 DONE
+✔ Syncing peer: monkha-1 DONE
+✔ Connecting: monkha-2 DONE
+✔ Syncing peer: monkha-2 DONE
+✔ Connecting: monkha-3 DONE
+✔ Syncing peer: monkha-3 DONE
+✔ Syncing nodes DONE
+✔ Cluster grown successfully
+```
+
+Once cluster is ready execute the same command as for local and select your cluster (the option will appear automatically).
+
+```bash
