## Getting Started

- [Getting Started](https://configcat.com/docs/getting-started.md): This is a step-by-step guide on how to get started with ConfigCat feature flags and on how to implement feature flags in an application.

## Main Concepts

- [Main Concepts](https://configcat.com/docs/main-concepts.md): This page explains the basics of feature flags and how to use them. Displays how configs, products and settings are organized within the feature flag service.

## Targeting

- [Feature Flag Evaluation](https://configcat.com/docs/targeting/feature-flag-evaluation.md): This document offers an in-depth explanation of how the ConfigCat SDK determines the value of a feature flag.
- [Percentage Options](https://configcat.com/docs/targeting/percentage-options.md): Using Percentage Options, you can define that a certain percentage of users should receive a specific value. This way, you can gradually release a new feature to a subset of users.
- [Targeting Overview](https://configcat.com/docs/targeting/targeting-overview.md): Overview of the ConfigCat targeting feature with examples.
- [Flag Condition (Prerequisite)](https://configcat.com/docs/targeting/targeting-rule/flag-condition.md): A Flag Condition is a condition that is based on the comparison of another feature flag's value and a preset value (comparison value).
