+# PagerDuty Incidents Cortex Plugin
+
+View PagerDuty incidents associated with your services!!
+
+<div align="center"><img src="img/pagerduty-incidents.png" /></div>
+
+The PagerDuty Incidents plugin shows PagerDuty incidents associated with the PagerDuty service specified in the entity's `cortex.yaml`. If the `cortex.yaml` has a PagerDuty service defined in its `x-cortex-oncall` configuration, it will query for incidents in that service. For example:
+
+```yaml
+openapi: 3.0.1
+info:
+  title: funrepo
+  description: Description of funrepo
+  x-cortex-tag: funrepo
+  x-cortex-type: service
+  x-cortex-oncall:
+    pagerduty:
+      id: PXXXXXX
+      type: SERVICE
+```
+
+## Setup
+
+This plugin requires a proxy to PagerDuty. To set up:
+
+- In PagerDuty, create an API Token by clicking on Integrations > API Access Keys > Create New API Key
+- In Cortex, define a secret whose value is your new token. Name it `pagerduty_secret`.
+- Create a plugin proxy in Cortex:
+
+  - Navigate to Plugins, then click on the Proxies tab, then click on Create Proxy
+  - Give the proxy a name, then click on Add URL
+  - For the URL Prefix, type in `https://api.pagerduty.com`
+  - Click on Add Header and add a header whose name is `Authorization` and whose value is `Token token={{{secrets.pagerduty_secret}}}` (include the curly braces!)
+
+- Once you are done, the proxy should look like the below:
+
+<div align="center"><img src="img/pagerduty-proxy.png"></div>
+
+Now, you can build and add the plugin.
+
+- Build the plugin:
+  - Make sure you have npm/yarn
+  - In your terminal, in the `pagerduty-incidents` directory, type `yarn` or `npm install` to install the dependencies
+  - Type `npm run build` or `yarn build` to build the plugin
+- The compiled plugin will be created in `dist/ui.html`
+- In Plugins > All, click **Register Plugin**
+- Give the plugin a name, like PagerDuty Incidents. This is the name users will see in the plugin listing.
+- Under **Associated Proxy**, choose the proxy you just created.
+- Under **Plugin Context**, click on Add another context; choose Selection type: Include, and Entity types: service.
+- This plugin does not work in the Global context. Turn off the switch labeled **Include in global context**
+- In The **Plugin code** section, upload the `dist/ui.html` file you just built.
+- Click on **Save plugin**
+
+Now, when you navigate to a Cortex entity that has a PagerDuty oncall associated with it, you should be able to click on Plugins > PagerDuty Incidents and see the PagerDuty incidents associated with the service that is linked to the entity.
+
+If no PagerDuty oncall is set for the entity, you will see a service chooser that allows you to map the entity to a PagerDuty service.
+
+<div align="center"><img src="img/pagerduty-chooser.png"></div>
+
+If you don't want to see the PagerDuty plugin at all on entities that don't have a PagerDuty oncall, then you can adjust the plugin visibility via CQL to only show in entities where `x-cortex-oncall.pagerduty.type = SERVICE`.
+
+# Setting up your dev environment
+
+PagerDuty Incidents Plugin is a [Cortex](https://www.cortex.io/) plugin. To see how to run the plugin inside of Cortex, see [our docs](https://docs.cortex.io/docs/plugins).
+
+### Prerequisites
+
+Developing and building this plugin requires either [yarn](https://classic.yarnpkg.com/lang/en/docs/install/) or [npm](https://docs.npmjs.com/downloading-and-installing-node-js-and-npm).
+
+## Getting started
+
+1. Run `yarn` or `npm install` to download all dependencies
+2. Run `yarn build` or `npm run build` to compile the plugin code into `./dist/ui.html`
+3. Upload `ui.html` into Cortex on a create or edit plugin page
+4. Add or update the code and repeat steps 2-3 as necessary
+
+### Notable scripts
+
+The following commands come pre-configured in this repository. You can see all available commands in the `scripts` section of [package.json](./package.json). They can be run with npm via `npm run {script_name}` or with yarn via `yarn {script_name}`, depending on your package manager preference. For instance, the `build` command can be run with `npm run build` or `yarn build`.
+
+- `build` - compiles the plugin. The compiled code root is `./src/index.tsx` (or as defined by [webpack.config.js](webpack.config.js)) and the output is generated into `dist/ui.html`.
+- `test` - runs all tests defined in the repository using [jest](https://jestjs.io/)
+- `lint` - runs lint and format checking on the repository using [prettier](https://prettier.io/) and [eslint](https://eslint.org/)
+- `lintfix` - runs eslint in fix mode to fix any linting errors that can be fixed automatically
+- `formatfix` - runs Prettier in fix mode to fix any formatting errors that can be fixed automatically
