+This part of the repo is responsible for provisioning our
+home-lab services using Ansible on top of the infrastructure already 
+created via Terraform.
+
+The basic pattern is to confiure the service, and then add the upstream host 
+to our reverse proxy (Caddy) configuration.
+
+![architecture image](archi.png)
+
+# TODOs (in-progress)
+1. reverse-proxy init
+1. minio user,bucket init
+1. static sites using minio bucket
+
+# Done
+1. Adding service to reverse-proxy (Caddy) via api
+1. Media Downloader with Transmission, and `*arr` services
+1. Plex
+1. Password Manager
+1. Nextcloud
+1. Metrics monitoring  
+
+---
+
+# Pre-reqs
+* `pip`3 - `sudo apt install python3 python3-pip`
+* `ansible` - `pip install --user ansible`
+
+# Execution
+1. (First Time Only) Fork this repo, if you haven't already.
+1. (FTO) Make sure that your [`hosts`](./hosts) have been created in the [Terraform](../terraform) section.
+1. (FTO) Edit `group_vars/all/vault.example` to your liking.
+```bash
+echo "YourSecretPassword" > vaultkey
+ansible-vault encrypt --output group_vars/all/vault --encrypt-vault-id vaultkey group_vars/all/vault.example
+git checkout group_vars/all/vault.example
+```
+1. View/edit your encrypted vault:
+```bash
+ansible-vault view/edit --vault-id vaultkey group_vars/all/vault
+```
+1. (FTO) Run the `init.yaml` playbook to install a service
+```bash
+ansible-playbook -u youruser -i hosts --vault-id vaultkey playbooks/init.yaml --tags=[app name]
+```
+1. Use another playbook to modify a service (not yet implemented but planned)
+```bash
+ansible-playbook -u youruser -i hosts --vault-id vaultkey playbooks/... --tags=[...]
+```
+
+# Ansible Roles
+You can think of each Role being an "app".
+
+Each Role has a `setup.yaml` task file responsible for installing the app.
+It may or may not have other task files depending on what other functionality this Role
+supports for this app.
+
+The `main.yaml` file in the Role determines the flow logic for which task files
+are getting run based on Tags for other functionalities (see Tags section below).
+
+
+# Artifacts
+The directory `playbooks/artifacts/` is a place where we save the output for some of the roles.
+
+This not only serves the purpose to tracking important state info for our configurations,
+but it also allows us to use some of this info in other parts of Ansible for cleaner automation.
+
+> Never commit this dir to git. It contains sensitive info! Its already configured to 
+be ignored by git.
+
+
+# Ansible Tags
+Setting up the app is normally done using the Role's name as the tag, 
+i.e. `--tags <role name>`.
+
+Any subsequent tasks required beyond setting up the app, will have a different 
+tag associated for those tasks (along with a different playbook to trigger them).
+For example, the MinIO Role will support adding a new user+bucket under the tag `add_minio_user`:
+
+```bash
+ansible-playbook ... playbooks/add_user.yaml --tags add_minio_user
+```
