+
+<img src="assets/example.png" alt="Alert example" style="width: 600px;"/>
+
+**prom2teams** is a HTTP server built with Python that receives alert notifications from a previously configured [Prometheus Alertmanager](https://github.com/prometheus/alertmanager) instance and forwards it to [Microsoft Teams](https://teams.microsoft.com/) using defined connectors.

+
+## Getting Started
+
+### Prerequisites
+
+The application has been tested with _Prometheus 1.7.1_, _Python 3.6.2_ and _pip 9.0.1_.
+
+Newer versions of _Prometheus/Python/pip_ should work but could also present issues.
+
+### Installing
+
+prom2teams could be installed using pip:
+
+```bash
+$ pip install prom2teams
+```
+
+## Usage
+
+```bash
+# To start the server (a config file path must be provided, Jinja2 template is optional):
+$ prom2teams start --configpath <config file path> [--templatepath <Jinja2 template file path>]
+
+# To show the help message:
+$ prom2teams --help
+```
+
+### Config file
+
+The config file is an [INI file](https://docs.python.org/3/library/configparser.html#supported-ini-file-structure) and should have the structure described below:
+
+```
+[HTTP Server]
+Host: <host ip> # default: 0.0.0.0
+Port: <host port> # default: 8089
+
+[Microsoft Teams]
+Connector: <webhook url> # required value
+```
+
+### Configuring Prometheus
+
+The [webhook receiver](https://prometheus.io/docs/alerting/configuration/#<webhook_config>) in Prometheus allows configuring a prom2teams server.
+
+The url is formed by the host and port defined in the previous step.
+
+```
+# The prom2teams endpoint to send HTTP POST requests to.
+url: 0.0.0.0:8089
+```
+
+### Templating
+
+prom2teams provides a [default template](app/teams/template.j2) built with [Jinja2](http://jinja.pocoo.org/docs/2.9/) to render messages in Microsoft Teams. This template could be overrided using the 'templatepath' argument ('--templatepath <Jinja2 template file path>') during the application start.
+
+## Built With
+![Python 3.6.2](https://img.shields.io/badge/Python-3.6.2-green.svg)
+![pip 9.0.1](https://img.shields.io/badge/pip-9.0.1-green.svg)
+
+## Versioning
+
+For the versions available, see the [tags on this repository](https://github.com/idealista/prom2teams/tags).
+
+Additionaly you can see what change in each version in the [CHANGELOG.md](CHANGELOG.md) file.
