-This tool helps to migrate PagerDuty configuration to Grafana OnCall.
+This tool helps to migrate your PagerDuty configuration to Grafana OnCall.

+## Overview
 
 Resources that can be migrated using this tool:
 
 - User notification rules
-- Escalation policies
 - On-call schedules
-- Integrations (services)
+- Escalation policies
+- Services (integrations)
+- Event rules (experimental, only works with global event rulesets)
 
 ## Limitations
 
 - Not all integration types are supported
-- Migrated on-call schedules in Grafana OnCall will use ICalendar files from PagerDuty
 - Delays between migrated notification/escalation rules could be slightly different from original.
   E.g. if you have a 4-minute delay between rules in PagerDuty, the resulting delay in Grafana OnCall will be 5 minutes
+- Manual changes to PD configuration may be required to migrate some resources
 
 ## Prerequisites
 
 1. Make sure you have `docker` installed
 2. Build the docker image: `docker build -t pd-oncall-migrator .`

+
+## Resources
+
+### User notification rules
+
+The tool is capable of migrating user notification rules from PagerDuty to Grafana OnCall.
+Notification rules from the `"When a high-urgency incident is assigned to me..."` section in PagerDuty settings are
+taken into account and will be migrated to default notification rules in Grafana OnCall for each user. Note that delays
+between notification rules may be slightly different in Grafana OnCall, see [Limitations](#limitations) for more info.
+
+When running the migration, existing notification rules in Grafana OnCall will be deleted for every affected user.
+
+Note that users are matched by email, so if there are users in the report with "no Grafana OnCall user found with
+this email" error, it's possible to fix it by adding these users to your Grafana organization.
+If there is a large number of unmatched users, please also [see the script](scripts/README.md) that can automatically
+create missing Grafana users via Grafana HTTP API.
+
+### On-call schedules
+
+The tool is capable of migrating on-call schedules from PagerDuty to Grafana OnCall.
+There are two ways to migrate on-call schedules:
+
+- Migrate on-call shifts as if they were created in Grafana OnCall web UI. Due to scheduling differences between
+PagerDuty and Grafana OnCall, it's sometimes impossible to automatically migrate on-call shifts without manual changes
+in PD. Pass `SCHEDULE_MIGRATION_MODE=web` to the tool to enable this mode.
+- Using ICalendar file URLs from PagerDuty. This way it's always possible to migrate schedules without any manual
+changes in PD, but resulting schedules in Grafana OnCall will be read-only. Pass `SCHEDULE_MIGRATION_MODE=ical` to the tool
+to enable this mode.
+
+On-call schedules will be migrated to new Grafana OnCall schedules with the same name as in PD. Any existing schedules
+with the same name will be deleted before migration. Any on-call schedules that reference unmatched users won't be
+migrated.
+
+When running the plan with `SCHEDULE_MIGRATION_MODE=web`, there could be a number of errors regarding on-call schedules.
+These errors are expected and are caused by the fact that the tool can't always automatically migrate on-call shifts
+due to differences in scheduling systems in PD and Grafana OnCall. To fix these errors, you need to manually change
+on-call shifts in PD and re-run the migration.
+
+### Escalation policies
+
+The tool is capable of migrating escalation policies from PagerDuty to Grafana OnCall.
+Every escalation policy will be migrated to a new Grafana OnCall escalation chain with the same name.
+
+Any existing escalation chains with the same name will be deleted before migration. Any escalation policies that reference
+unmatched users or schedules that cannot be migrated won't be migrated as well.
+
+Note that delays between escalation steps may be slightly different in Grafana OnCall,
+see [Limitations](#limitations) for more info.
+
+### Services (integrations)
+
+The tool is capable of migrating services (integrations) from PagerDuty to Grafana OnCall.
+For every service in PD, the tool will migrate all integrations to Grafana OnCall integrations.
+
+Any services that reference escalation policies that cannot be migrated won't be migrated as well.
+Any integrations with unsupported type won't be migrated unless `UNSUPPORTED_INTEGRATION_TO_WEBHOOKS` is set to `true`.
+
+### Event rules (global event rulesets)
+
+The tool is capable of migrating global event rulesets from PagerDuty to Grafana OnCall integrations. This feature is
+experimental and disabled by default. To enable it, set `EXPERIMENTAL_MIGRATE_EVENT_RULES` to `true`.
+
+For every ruleset in PD, the tool will create a webhook integration in Grafana OnCall. The tool will create
+a route for every rule in ruleset, converting conditions in PD to Jinja2 routes in Grafana OnCall. The tool will also
+select appropriate escalation chains for each route based on service referenced in the rule.
+
+If you want to include service & integration names in the names of migrated integrations, set
+`EXPERIMENTAL_MIGRATE_EVENT_RULES_LONG_NAMES` to `true` (note that this only applies when
+`EXPERIMENTAL_MIGRATE_EVENT_RULES` is `true`). This can make searching for integrations easier,
+but it can also make the names of integrations too long.
+
+## After migration
 
 - Connect integrations (press the "How to connect" button on the integration page)
 - Make sure users connect their phone numbers, Slack accounts, etc. in their user settings
