+At a high level, Eraser has two main modes of operation: manual and automated.
+
+Manual image removal involves supplying a list of images to remove; Eraser then
+deploys pods to clean up the images you supplied.
+
+Automated image removal runs on a timer. By default, the automated process
+removes images based on the results of a vulnerability scan. The default
+vulnerability scanner is Trivy, but others can be provided in its place. Or,
+the scanner can be disabled altogether, in which case Eraser acts as a garbage
+collector -- it will remove all non-running images in your cluster.

+## Creating a Custom Scanner
+To create a custom scanner for non-compliant images, use the following [template](https://github.com/eraser-dev/eraser-scanner-template/).
+
+In order to customize your scanner, start by creating a `NewImageProvider()`. The ImageProvider interface can be found can be found [here](../../pkg/scanners/template/scanner_template.go). 
+
+The ImageProvider will allow you to retrieve the list of all non-running and non-excluded images from the collector container through the `ReceiveImages()` function. Process these images with your customized scanner and threshold, and use `SendImages()` to pass the images found non-compliant to the eraser container for removal. Finally, complete the scanning process by calling `Finish()`.
+
+When complete, provide your custom scanner image to Eraser in deployment.

+
+## Overview
+
+Eraser uses a configmap to configure its behavior. The configmap is part of the
+deployment and it is not necessary to deploy it manually. Once deployed, the configmap
+can be edited at any time:
+
+```bash
+kubectl edit configmap --namespace eraser-system eraser-manager-config
+```
+
+If an eraser job is already running, the changes will not take effect until the job completes.
+The configuration is in yaml.
+
+## Key Concepts
+
+### Basic architecture
+
+The _manager_ runs as a pod in your cluster and manages _ImageJobs_. Think of
+an _ImageJob_ as a unit of work, performed on every node in your cluster. Each
+node runs a sub-job. The goal of the _ImageJob_ is to assess the images on your
+cluster's nodes, and to remove the images you don't want. There are two stages:
+1. Assessment
+1. Removal.
+
+
+### Scheduling
+
+An _ImageJob_ can either be created on-demand (see [Manual Removal](https://eraser-dev.github.io/eraser/docs/manual-removal)),
+or they can be spawned on a timer like a cron job. On-demand jobs skip the
+assessment stage and get right down to the business of removing the images you
+specified. The behavior of an on-demand job is quite different from that of
+timed jobs.
+
+### Fault Tolerance
+
+Because an _ImageJob_ runs on every node in your cluster, and the conditions on
+each node may vary widely, some of the sub-jobs may fail. If you cannot
+tolerate any failure, set the `manager.imageJob.successRatio` property to
+`1.0`. If 75% success sounds good to you, set it to `0.75`. In that case, if
+fewer than 75% of the pods spawned by the _ImageJob_ report success, the job as
+a whole will be marked as a failure.
+
+This is mainly to help diagnose error conditions. As such, you can set
+`manager.imageJob.cleanup.delayOnFailure` to a long value so that logs can be
+captured before the spawned pods are cleaned up.
+
+### Excluding Nodes
+
+For various reasons, you may want to prevent Eraser from scheduling pods on
+certain nodes. To do so, the nodes can be given a special label. By default,
+this label is `eraser.sh/cleanup.filter`, but you can configure the behavior with
+the options under `manager.nodeFilter`. The [table](#detailed-options) provides more detail.
+
+### Configuring Components
+
+An _ImageJob_ is made up of various sub-jobs, with one sub-job for each node.
+These sub-jobs can be broken down further into three stages.
+1. Collection (What is on the node?)
+1. Scanning (What images conform to the policy I've provided?)
+1. Removal (Remove images based on the results of the above)
+
+Of the above stages, only Removal is mandatory. The others can be disabled.
+Furthermore, manually triggered _ImageJobs_ will skip right to removal, even if
+Eraser is configured to collect and scan. Collection and Scanning will only
+take place when:
+1. The collector and/or scanner `components` are enabled, AND
+1. The job was *not* triggered manually by creating an _ImageList_.
+
+### Swapping out components
+
+The collector, scanner, and remover components can all be swapped out. This
+enables you to build and host the images yourself. In addition, the scanner's
+behavior can be completely tailored to your needs by swapping out the default
+image with one of your own. To specify the images, use the
+`components.<component>.image.repo` and `components.<component>.image.tag`,
+where `<component>` is one of `collector`, `scanner`, or `remover`.
+
+## Universal Options
+
+The following portions of the configmap apply no matter how you spawn your
+_ImageJob_. The values provided below are the defaults. For more detail on
+these options, see the [table](#detailed-options).
+
+```yaml
+manager:
+  runtime: containerd
+  otlpEndpoint: "" # empty string disables OpenTelemetry
+  logLevel: info
+  profile:
+    enabled: false
+    port: 6060

+    successRatio: 1.0
+    cleanup:
+      delayOnSuccess: 0s
+      delayOnFailure: 24h
+  pullSecrets: [] # image pull secrets for collector/scanner/remover
+  priorityClassName: "" # priority class name for collector/scanner/remover
+  nodeFilter:
+    type: exclude # must be either exclude|include
+    selectors:
+      - eraser.sh/cleanup.filter
+      - kubernetes.io/os=windows

+
+## Component Options
+
+```yaml

+```
+
+## Scanner Options
+
+These options can be provided to `components.scanner.config`. They will be
+passed through  as a string to the scanner container and parsed there. If you
+want to configure your own scanner, you must provide some way to parse this.
+
+Below are the values recognized by the provided `eraser-trivy-scanner` image.
+Values provided below are the defaults.
+
+```yaml
+cacheDir: /var/lib/trivy # The file path inside the container to store the cache
+dbRepo: ghcr.io/aquasecurity/trivy-db # The container registry from which to fetch the trivy database
+deleteFailedImages: true # if true, remove images for which scanning fails, regardless of why it failed
+deleteEOLImages: true # if true, remove images that have reached their end-of-life date
+vulnerabilities:
+  ignoreUnfixed: true # consider the image compliant if there are no known fixes for the vulnerabilities found.
+  types: # a list of vulnerability types. for more info, see trivy's documentation.
+    - os
+    - library
+  securityChecks: # see trivy's documentation for more invormation
+    - vuln
+  severities: # in this case, only flag images with CRITICAL vulnerability for removal
+    - CRITICAL
+timeout:
+  total: 23h # if scanning isn't completed before this much time elapses, abort the whole scan
+  perImage: 1h # if scanning a single image exceeds this time, scanning will be aborted
+```
