 Simply put, Blockchain is a shared, immutable ledger for recording transactions, tracking assets and building trust. Head over to [Blockchain Basics](blockchain-basics/blockchain) to read more.

-### What is a Sidechain?
+## What is a Sidechain?
 Think of a Sidechain as a clone of a 'parent' blockchain, supporting transfer of assets to and from the main chain. It is simply an alternate to parent chain that creates a new blockchain with its own mechanism of creating blocks (consensus mechanism). Connecting a sidechain to a parent chain involves setting up a method of moving assets between the chains.

-### What is Plasma?
-Plasma is a framework of secondary chains that will communicate and interact as sparingly as possible with the main chain. Child chain is a scaling solution for Ethereum (or any blockchain for that matter).
-It is a layer 2 solution for Ethereum that provides a framework for building ‘off-chain’ decentralised applications that are secure, scalable and swift.

+## Validator and delegator roles
+
+On the Polygon Network, you can be a validator or a delegator. See:
+
+* [Who Is a Validator](/docs/validate/polygon-basics/who-is-validator)
+* [Who Is a Delegator](/docs/validate/polygon-basics/who-is-delegator)
+
+## Architecture
+
+If your goal is to become a validator, it is essential that you understand the Polygon architecture.
+
+See [Polygon Architecture](/docs/validate/validator/architecture).
+
+### Components
+
+To have a granular understanding of the Polygon architecture, see core components:
+
+* [Heimdall](/docs/contribute/heimdall/overview)
+* [Bor](/docs/contribute/bor/overview)
+* [Contracts](/docs/contribute/contracts/stakingmanager)
+
+#### Codebases
+
+To have a granular understanding of the core components, see the codebases:
+
+* [Heimdall](https://github.com/maticnetwork/heimdall)
+* [Bor](https://github.com/maticnetwork/bor)
+* [Contracts](https://github.com/maticnetwork/contracts)
+
+## How-tos
+
+### Node setup

+* [Run a Validator Node with Ansible](/docs/validate/validate/run-validator-ansible)
+* [Run a Validator Node from Binaries](/docs/validate/validate/run-validator-binaries)

 For every few blocks on Bor, a validator on the Heimdall layer:
 
 1. Validates all the blocks since the last checkpoint.
 2. Creates a Merkle tree of the block hashes.
 3. Publishes the Merkle root hash to the Ethereum mainnet.
