+
+### Filtering enabled collectors
+
+The `windows_exporter` will expose all metrics from enabled collectors by default.  This is the recommended way to collect metrics to avoid errors when comparing metrics of different families.
+
+For advanced use the `windows_exporter` can be passed an optional list of collectors to filter metrics. The `collect[]` parameter may be used multiple times. In Prometheus configuration you can use this syntax under the [scrape config](https://prometheus.io/docs/prometheus/latest/configuration/configuration/#<scrape_config>).
+
+```
+  params:
+    collect[]:
+      - foo
+      - bar
+```
+
+This can be useful for having different Prometheus servers collect specific metrics from nodes.
+
+## Flags
+
+windows_exporter accepts flags to configure certain behaviours. The ones configuring the global behaviour of the exporter are listed below, while collector-specific ones are documented in the respective collector documentation above.
+
+Flag     | Description | Default value
+---------|-------------|--------------------
+`--telemetry.addr` | host:port for exporter. | `:9182`
+`--telemetry.path` | URL path for surfacing collected metrics. | `/metrics`
+`--telemetry.max-requests` | Maximum number of concurrent requests. 0 to disable. | `5`
+`--collectors.enabled` | Comma-separated list of collectors to use. Use `[defaults]` as a placeholder which gets expanded containing all the collectors enabled by default." | `[defaults]`
+`--collectors.print` | If true, print available collectors and exit. |
+`--scrape.timeout-margin` | Seconds to subtract from the timeout allowed by the client. Tune to allow for overhead or high loads. | `0.5`
+`--web.config.file` | A [web config][web_config] for setting up TLS and Auth | None
 
 ## Installation
-Each release provides a .msi installer. The installer will setup the WMI Exporter as a Windows service, as well as create an exception in the Windows Firewall.
+The latest release can be downloaded from the [releases page](https://github.com/prometheus-community/windows_exporter/releases).

+Each release provides a .msi installer. The installer will setup the windows_exporter as a Windows service, as well as create an exception in the Windows Firewall.
 
 If the installer is run without any parameters, the exporter will run with default settings for enabled collectors, ports, etc. The following parameters are available:
 
 Name | Description
 -----|------------
-`ENABLED_COLLECTORS` | As the `-collectors.enabled` flag, provide a comma-separated list of enabled collectors
+`ENABLED_COLLECTORS` | As the `--collectors.enabled` flag, provide a comma-separated list of enabled collectors
 `LISTEN_ADDR` | The IP address to bind to. Defaults to 0.0.0.0
 `LISTEN_PORT` | The port to bind to. Defaults to 9182.
 `METRICS_PATH` | The path at which to serve metrics. Defaults to `/metrics`
+`TEXTFILE_DIR` | As the `--collector.textfile.directory` flag, provide a directory to read text files with metrics from
+`REMOTE_ADDR` | Allows setting comma separated remote IP addresses for the Windows Firewall exception (whitelist). Defaults to an empty string (any remote address).
+`EXTRA_FLAGS` | Allows passing full CLI flags. Defaults to an empty string.
 
-Parameters are sent to the installer via `msiexec`. Example invocation:
+Parameters are sent to the installer via `msiexec`. Example invocations:
 
 ```powershell
 msiexec /i <path-to-msi-file> ENABLED_COLLECTORS=os,iis LISTEN_PORT=5000
 ```
 
-## Roadmap
+Example service collector with a custom query.
+```powershell
+msiexec /i <path-to-msi-file> ENABLED_COLLECTORS=os,service --% EXTRA_FLAGS="--collector.service.services-where ""Name LIKE 'sql%'"""
+```
 
-See [open issues](https://github.com/martinlindhe/wmi_exporter/issues)
+On some older versions of Windows you may need to surround parameter values with double quotes to get the install command parsing properly:
+```powershell
+msiexec /i C:\Users\Administrator\Downloads\windows_exporter.msi ENABLED_COLLECTORS="ad,iis,logon,memory,process,tcp,thermalzone" TEXTFILE_DIR="C:\custom_metrics\"
+```
 
 
+## Kubernetes Implementation
+
+See detailed steps to install on Windows Kubernetes [here](./kubernetes/kubernetes.md).
+
+## Supported versions
+
+windows_exporter supports Windows Server versions 2008R2 and later, and desktop Windows version 7 and later.
+
 ## Usage
 
-    go get -u github.com/kardianos/govendor
-    go get -u github.com/martinlindhe/wmi_exporter
-    cd $env:GOPATH/src/github.com/martinlindhe/wmi_exporter
-    govendor build +local
-    .\wmi_exporter.exe
+    go get -u github.com/prometheus/promu
+    go get -u github.com/prometheus-community/windows_exporter
+    cd $env:GOPATH/src/github.com/prometheus-community/windows_exporter
+    promu build -v
+    .\windows_exporter.exe
 
 The prometheus metrics will be exposed on [localhost:9182](http://localhost:9182)
 
+## Examples
+
+### Enable only service collector and specify a custom query
+
+    .\windows_exporter.exe --collectors.enabled "service" --collector.service.services-where "Name='windows_exporter'"
+
+### Enable only process collector and specify a custom query
+
+    .\windows_exporter.exe --collectors.enabled "process" --collector.process.whitelist="firefox.+"
+
+When there are multiple processes with the same name, WMI represents those after the first instance as `process-name#index`. So to get them all, rather than just the first one, the [regular expression](https://en.wikipedia.org/wiki/Regular_expression) must use `.+`. See [process](docs/collector.process.md) for more information.
+
+### Using [defaults] with `--collectors.enabled` argument
+
+Using `[defaults]`  with `--collectors.enabled` argument which gets expanded with all default collectors.
+
+    .\windows_exporter.exe --collectors.enabled "[defaults],process,container"
+
+This enables the additional process and container collectors on top of the defaults.
+
+### Using a configuration file
+
+YAML configuration files can be specified with the `--config.file` flag. E.G. `.\windows_exporter.exe --config.file=config.yml`
+
+```yaml
+collectors:
+  enabled: cpu,cs,net,service
+collector:
+  service:
+    services-where: "Name='windows_exporter'"
+log:
+  level: warn
+```
+
+An example configuration file can be found [here](docs/example_config.yml).
+
+#### Configuration file notes
+
+Configuration file values can be mixed with CLI flags. E.G.
+
+`.\windows_exporter.exe --collectors.enabled=cpu,logon`
+
+```yaml
+log:
+  level: debug
+```
+
+CLI flags enjoy a higher priority over values specified in the configuration file.
