## Overview

### Working with lucicfg
{{template "todo"}}

### Concepts
{{template "todo"}}

### Resolving naming ambiguities
{{template "todo"}}

### Defining durations {#durations_doc}
{{template "todo"}}

### Defining cron schedules {#schedules_doc}
{{template "todo"}}

## Core rules
{{template "gen-funcs-doc" $core}}

## ACLs

### Roles {#roles_doc}

Below is the table with role constants that can be passed as `roles` in
{{LinkifySymbols "acl.entry(...)"}}.

Due to some inconsistencies in how LUCI service are currently implemented, some
roles can be assigned only in {{LinkifySymbols "core.project(...)"}} rule, but
some also in individual {{LinkifySymbols "core.bucket(...)"}} rules.

Similarly some roles can be assigned to individual users, other only to groups.

| Role  | Scope | Principals | Allows |
|-------|-------|------------|--------|
{{- range $sym := $acl.Symbols "var"}}
| {{.FullName}} |
{{- if .HasDocTag "project_level_only"}}project only{{else}}project, bucket{{end}} |
{{- if .HasDocTag "groups_only"}}groups{{else}}groups, users{{end}} |
{{- .Doc.Description | LinkifySymbols}} |
{{- end}}

{{template "gen-funcs-doc" $acl}}

## Swarming
{{template "gen-funcs-doc" $swarming}}

## Other builtin functions

These functions are available in the global namespace.
