docs(beta): simplify install steps — no shell vars, no fresh/upgrade split

Drop $WSAVAIL_DIR and $NODE_TAG. Operators just cd into their existing
checkout and run the commands as-is.

config.py step is now idempotent: keep existing, otherwise copy from
sample. No verb branching between "fresh install" and "upgrade".

+Beta release. API-compatible with v1.0.5.
 
 ## Prerequisites
 
-- Docker with the `docker-compose` v1.x (or `docker compose` v2) plugin.
-- Running WFCatalog MongoDB ≥ 4.2 reachable from the host.
+- Docker with `docker-compose` (v1) or `docker compose` (v2).
+- WFCatalog MongoDB ≥ 4.2 reachable from the host.
 - Port 9001 free on the host.
-- ~2 GB RAM.
 
 ## Install
 
-Set two shell variables once. Replace `<your_node>` with a short tag (`noa`, `resif`, `orfeus`, …).
+`cd` into your `ws-availability` checkout (or `git clone https://github.com/EIDA/ws-availability.git` if you don't have one yet), then:
 
-```bash
-export WSAVAIL_DIR=/path/to/your/ws-availability/checkout    # adjust
-export NODE_TAG=<your_node>                                  # adjust
-```
-
-1. Back up.
-
-   ```bash
-   cd "$WSAVAIL_DIR"
-   cp config.py "$HOME/config.py.pre-1.1.0-beta.bak" 2>/dev/null || true
-   crontab -l > "$HOME/crontab.pre-1.1.0-beta.bak" 2>/dev/null || true
-   git rev-parse HEAD > "$HOME/ws-availability.pre-1.1.0-beta.commit" 2>/dev/null || true
-   ```

-2. Check out the beta.
+1. Check out the beta.
 
    ```bash
    git fetch --tags origin
    git checkout v1.1.0-beta.1
    ```
 
-3. Set the per-node Sentry tag.
-
-   ```bash
-   echo "SENTRY_ENVIRONMENT=${NODE_TAG}_production" > .env
-   ```
-
-4. If this is a first install, copy and edit `config.py`. (Skip on upgrade — your existing `config.py` is kept.)
-
-   ```bash
-   cp config.py.sample config.py
-   $EDITOR config.py
-   ```
-
-5. Build images.
+2. `config.py` — keep your existing one if you already have it; otherwise copy the sample and edit:
 
    ```bash
-   docker-compose build api cacher
+   [ -f config.py ] || cp config.py.sample config.py
+   $EDITOR config.py    # set MONGODB_*, FDSNWS_STATION_URL, SENTRY_DSN
    ```
 
-6. Replace the API container.
+3. Set your node's Sentry tag (replace `noa` with your node short name):
 
    ```bash
-   docker-compose up -d --no-deps --build api
+   echo "SENTRY_ENVIRONMENT=noa_production" > .env
    ```
 
-7. Replace the cacher container.
+4. Build and start.
 
    ```bash
-   docker-compose up -d --no-deps --build cacher
+   docker-compose build
+   docker-compose up -d
    ```
 
-   Wait for the cacher startup tasks to finish:
-
-   ```bash
-   docker logs -f fdsnws-availability-cacher 2>&1 | grep --line-buffered -E "Scheduler started|ERROR|Traceback"
-   ```
-
-   Stop tailing (`Ctrl-C`) once you see `Scheduler started`.
-
-8. If your node had a host cron triggering `views/main.js`, remove it. It is now redundant.

    ```bash
    crontab -l | grep -v "ws-availability.*views.*main.js" | crontab -
    ```
