+Build a Nextcloud instance in Docker Compose complete with PostgreSQL, Redis and SSL
+
+# Prerequisites
+
+1. [Docker](https://docs.docker.com/engine/install/)
+2. [Docker Compose](https://docs.docker.com/compose/install/)
+3. SSL key and cert
+
+# Setup
+
+1. Create a copy of `.env.example`:
+
+```bash
+cp .env.example .env
+```
+
+2. Replace the `SSL_CERT_PATH` and `SSL_KEY_PATH` variables in the newly created `.env` file to point to your SSL key and cert

+4. Replace `VOLUME_PATH` variable if you wish to change where volume data is stored
+
+5. Modify other variables as needed

+
+```bash
+# Postgres
+echo "SuperSecretPassword" > secrets/postgres_password.txt # Replace with your own super secret password
+
+# Nextcloud
+echo "admin" > secrets/nextcloud_admin_user.txt                   # Replace with desired admin username
+echo "SuperSecretPassword" > secrets/nextcloud_admin_password.txt # Replace with super secret password for admin Nextcloud user
+```
+

+
+```bash
+sudo docker-compose up --build -d
+```
