 Images may not be shown although you see them in a preview. It is likely because the paths are slightly different in the generated files and you might need to go one level back to the parent folder.
 e.g. [check here](https://github.com/Linguly/docs/blob/main/docs/setup/how-to-setup.md?plain=1#L40)
 
+### Cross reference path is not working in the final doc
+Similar to images, any other path need an extra move to the parent directory (`../`).

+# Mongodb for development or self-host
+
+For most of our functionalities we are using Mongodb primarily.
+To have an easy local setup similar to the deployed version, we recommend to use the free tier of [MongoDB Atlas](https://www.mongodb.com/atlas).
+There you can simply create an account [here](https://www.mongodb.com/atlas) and select the free tier.
+Then create a connection url and update the `.env` file based on the Database instance you want to configure ([e.g. here in Linguly Core](https://github.com/Linguly/linguly-core?tab=readme-ov-file#environment-variables-for-local-setup)).
+Create the DBs and collections as you need.
+
+
+## Setup in Coolify
+
+Mongodb setup in Coolify is straight forward:
+
+- Create a new resource
+- Select Mongodb and then Coolify will create a URL which include username and password
+- Start the DB
+- Copy the URL and paste it the mongodb url environment variable of the services you want e.g. [Linguly Core](https://github.com/Linguly/linguly-core)

+To have an easy local setup just install it locally and make sure it is running when you are running any service depending on it e.g. [Telegram Interface](https://github.com/Linguly/telegram-interface).
