+# NAxS Homelab
+## Prerequisites
+0. Make sure that your user is part of the docker group
+  - `cat /etc/group | grep docker` - if the entry looks like `docker:x:<Group ID>:<username>`, you're good to go
+  - Otherwise please run `sudo usermod -aG docker <username>`, followed by logging out & in again for these changes to take into effect
+
+1. Create a default network called homelab
+```
+docker network create homelab
+```
+2. Set up 1Password for access to secrets
+  - Install `pass` & `gpg`
+  - Generate key with `gpg --full-generate-key`
+    - stick to defaults
+    - as password, use `GPG cert password` stored inside the `NAxS Homelab` vault in 1Password
+  - Initialize password storage with `pass init "GPG key ID"`
+    - You can check out the ID by using `gpg --list-secret-keys --keyid-format LONG` - you should see a line with `sec`, containing the following information `<encryption technology>/ID`
+  - Store the 1Password service account token in `pass` as `op-sa_token` by executing `pass insert op-sa_token`
+  - Make sure your .zshrc file loads the token into the `OP_SERVICE_ACCOUNT_TOKEN` (this is needed by the 1Password CLI for authentication purposes when loading the secrets) environment variable by executing `export OP_SERVICE_ACCOUNT_TOKEN="$(pass op-sa_token)"`
+
+// TODO: Create template script
+Template script which helps with setting up new applications (asks for potential secrets needs, adds default network to compose file, creates new users/groups to run containers rootless)

+## Secrets Management
+
+This application utilizes secrets for sensitive configurations (e.g., database credentials, API keys).
+
+### Configuration
+Secrets are expected to be provided via environment variables or Docker Compose secrets.
+Refer to the \`start.sh\` script for an example of how to load these secrets before application startup.
+
+**Example Environment Variables (to be set in your environment or a \`.env\` file):**
+\`\`\`
+DATABASE_URL="postgres://user:password@host:port/database"
+API_KEY="your_super_secret_api_key"
+\`\`\`
+
+**For Docker Compose secrets:**
+Ensure the necessary Docker secrets are created on your Docker host or Swarm cluster.
+\`\`\`bash
+docker secret create my_database_password <(echo "your_db_password")
+docker secret create my_api_key <(echo "your_api_key")
+\`\`\`
+Then, update the \`compose.yaml\` to reference these secrets.

+# Gitea
+## Prerequisites
+### Set up database
+- Create database called `gitea` in Postgres
+
+### Set up non-root user for container
+We are providing a non-root user to the container to limit the attack surface for privilege escalations. In order for this to work in our setup, please make sure to check if you have a user called `gitea` set up
+
+1. Check if user `gitea`
+
+```
+cat /etc/passwd | grep gitea
+```
+
+In case user doesn't exist, please create the user by running
+```
+sudo useradd gitea
+```
+
+2. `data` & `config` folder ownership
+Also you need to make sure that the `gitea` owner owns the volumes mounted for docker
+```
+sudo chown -R gitea:gitea data
+sudo chmod 770 data
+
+sudo chown -R gitea:gitea config
+sudo chmod 770 config
+```
+
+3. Adjust compose.yml
+Within `services > gitea > user`, make sure to replace `gitea` with the UID of the user on your machine
+```
+cat /etc/passwd | grep gitea
+```
+
+## Initial setup
+1. `docker compose up -d`
+2. Open IP:8030 and continue set up

+## Set up non-root user for container

+
+1. Check if user `postgres` exists

+
+## About secrets
+In order to manage secrets centrally in 1Password and due to the need for secrets in Postgres, using `docker compose` directly in the terminal does not work. 
+
+## Bring up/tear down container
+Please use the `start.sh` to spin up the container
+### Prerequisites start.sh
+- User executing the script is part of the `docker` group
+- Environment variable `OP_SERVICE_ACCOUNT_TOKEN` is set up \[check out top-level README.md for more information on how to set this up\]
