+## Features
+
+- [x] Creates & Resolves Incidents
+- [x] Posts monitor lag to cachet graphs
+- [x] HTTP Checks (body/status code)
+- [x] DNS Checks
+- [x] Updates Component to Partial Outage
+- [x] Updates Component to Major Outage if already in Partial Outage (works with distributed monitors)
+- [x] Can be run on multiple servers and geo regions
+
+## Example Configuration
+
+**Note:** configuration can be in json or yaml format. [`example.config.json`](https://github.com/CastawayLabs/cachet-monitor/blob/master/example.config.json), [`example.config.yaml`](https://github.com/CastawayLabs/cachet-monitor/blob/master/example.config.yml) files.

+
+## Installation
+
+1. Download binary from [release page](https://github.com/CastawayLabs/cachet-monitor/releases)
+2. Create a configuration
+3. `cachet-monitor -c /etc/cachet-monitor.yaml`
+
+pro tip: run in background using `nohup cachet-monitor 2>&1 > /var/log/cachet-monitor.log &`
+
+```
+Usage:
+  cachet-monitor (-c PATH | --config PATH) [--log=LOGPATH] [--name=NAME] [--immediate]
+  cachet-monitor -h | --help | --version
+
+Arguments:
+  PATH     path to config.json
+  LOGPATH  path to log output (defaults to STDOUT)
+  NAME     name of this logger
+
+Examples:
+  cachet-monitor -c /root/cachet-monitor.json
+  cachet-monitor -c /root/cachet-monitor.json --log=/var/log/cachet-monitor.log --name="development machine"
+
+Options:
+  -c PATH.json --config PATH     Path to configuration file
+  -h --help                      Show this screen.
+  --version                      Show version
+  --immediate                    Tick immediately (by default waits for first defined interval)
+  
+Environment varaibles:
+  CACHET_API      override API url from configuration
+  CACHET_TOKEN    override API token from configuration
+  CACHET_DEV      set to enable dev logging
+```
+
+## Templates
+
+This package makes use of [`text/template`](https://godoc.org/text/template). [Default HTTP template](https://github.com/CastawayLabs/cachet-monitor/blob/master/http.go#L14)
+
+The following variables are available:
+
+| Root objects  |
+| ------------- | -----------------
+| `.SystemName` | system name
+| `.API`        | `api` object from configuration
+| `.Monitor`    | `monitor` object from configuration
+| `.now`        | formatted date string
+
+| Monitor variables  |
+| ------------------ |
+| `.Name`            |
+| `.Target`          |
+| `.Type`            |
+| `.Strict`          |
+| `.MetricID`        |
+| ...                |
+
+All monitor variables are available from `monitor.go`
+
+## Vision and goals
+
+We made this tool because we felt the need to have our own monitoring software (leveraging on Cachet).
+The idea is a stateless program which collects data and pushes it to a central cachet instance.
+
+This gives us power to have an army of geographically distributed loggers and reveal issues in both latency & downtime on client websites.
+
+## Package usage
+
+When using `cachet-monitor` as a package in another program, you should follow what `cli/main.go` does. It is important to call `Validate` on `CachetMonitor` and all the monitors inside.
+
+[API Documentation](https://godoc.org/github.com/CastawayLabs/cachet-monitor)
+
+# Contributions welcome
+
+We'll happily accept contributions for the following (non exhaustive list).
+
+- Implement ICMP check
+- Implement TCP check
+- Any bug fixes / code improvements
+- Test cases
