+# Overleaf Setup
+
+## Getting started
+
+1. Upload the docker-compose.yaml to the server directory.
+2. Start the MongoDB alone using `docker compose up -d mongo` and wait about 15 seconds for it to start.
+3. Execute the script [setup-replica-set.sh](setup-replica-set.sh) to create the ReplicaSet, required by the sharedlatex
+   container
+4. Now start all other containers using `docker compose up -d`
+
+## Docker Overview
+
+1. What does the Compose stack contain?
+```
+    The compose stack consists of three containers.
+    The sharelatex container is the actual Overleaf application, 
+    containing the frontend and the backend of the application.
+    It requires two different datasources, a MongoDB and a Redis.
+```
+
+2. How to access the application?
+```
+    The docker-compose.yaml file in this repository is setup to 
+    automatically connect to a running [Treafik](https://traefik.io) 
+    instance. If a different reverse proxy is used, the traefik labels 
+    can be removed and the required configuration has to be added.
+```
+
+3. Why setting up a ReplicaSet with a single MongoDB instance?
+```
+   The Overleaf application depends on using transactions. Transactions are 
+   only supported by MongoDB if a Replica Set is active.
+```
+
+4. Where is the data stored?
+```
+   All relevant data from each container is bound to a Docker volume each.
+```
