 ## Installation
-### Using uv (recommended)
-* Install `uv` and make the plugin executable
-```
-pip install --upgrade pip uv
-chmod a+x prometheus.py
-```
-Then you can add _just that file_ to your Core Lightning plugins directory. The plugin should start automatically and its dependencies will be installed on-the-fly when the node comes up.
-
-### Using poetry (legacy)
-If you don't want to use `uv`, you can still use `poetry`. You need to update the shebang line to point the OS at the correct interpreter (`python3`) though:
-```
-sed -i 's#-S uv run --script#python3#' prometheus.py
-```
+You need [uv](https://docs.astral.sh/uv/getting-started/installation/) to run this
+plugin like a binary. After `uv` is installed you can simply run
 
-Then install `poetry` and build the package:
 ```
-pip install --upgrade pip poetry
-poetry install --only main
+lightning-cli plugin start /path/to/prometheus.py
 ```
 
-This is an example snippet for installing the plugin's dependencies and cleaning up afterwards:
-```
-PLUGIN_PATH=/opt/plugins
-RAW_GH_PLUGINS=https://raw.githubusercontent.com/lightningd/plugins/master
-mkdir -p ${PLUGIN_PATH}
-
-pip3 install --break-system-packages --upgrade pip wheel poetry
-
-# Add custom plugins (prometheus)
-## This replaces the shebang line that by default uses uv for package management
-(cd $PLUGIN_PATH; wget -q $RAW_GH_PLUGINS/prometheus/README.md \
-  && wget -q $RAW_GH_PLUGINS/prometheus/pyproject.toml \
-  && wget -q $RAW_GH_PLUGINS/prometheus/poetry.lock \
-  && wget -q $RAW_GH_PLUGINS/prometheus/prometheus.py \
-  && sed -i 's#-S uv run --script#python3#' prometheus.py \
-  && poetry config virtualenvs.create false \
-  && PIP_BREAK_SYSTEM_PACKAGES=1 poetry install --only main \
-  && rm -f README.md pyproject.toml poetry.lock)
-
-chmod a+x $PLUGIN_PATH/*
-```
