 Blockchain networks often times need to upgrade with new features
 which require coordination work among the validators prior to activating
 the upgrades.
 
-This process is called a hardfork or a network upgrade. In those events,
-the Celestia Labs team will be coordinating with the validators on
-what they need to do in order to be ready for an upcoming hardfork.
+This process is called a network upgrade, which can be breaking or non-breaking.
+During planned network upgrades, the Celestia Labs team will coordinate
+with the validators to prepare for the upcoming network upgrade.
 
-Hardforks are not backward-compatible with older versions of the network
+Breaking network upgrades are not backward-compatible with older versions of the network
 software which is why it is important that validators upgrade their software
 to continue validating on the network after the network upgrades.
 
+Non-breaking network upgrades are backward-compatible and require less coordination.

 ## General process
 
 The general process can be broken down into several components:
 
-- Hardfork specifications and features (defined by description of features
+- Network upgrade specifications and features (defined by description of features
   and code implementation of those features).
-- Binary used to add those features (a new binary release with those features
-  will be provided by Celestia team in order for validators to upgrade
-  their nodes to the new binary).
-- A block number for when the network upgrades (even if validators upgrade
-  their binary to be hardfork ready, the network upgrade does not happen right
-  away, but some short time in the future at a specific block number).
-- Testing of the features (happens on testnets first prior to activating on
-  mainnet in order to ensure the network can upgrade securely).

-The Lemongrass hardfork is the first consensus layer breaking change since Celestia's Mainnet Beta genesis block. The Lemongrass hardfork includes all of the CIPs listed in [CIP-17](https://github.com/celestiaorg/CIPs/blob/main/cips/cip-17.md). The Lemongrass hardfork will be executed on Arabica, then Mocha, then Mainnet Beta. The hardfork will take place at an "upgrade height" that will be coordinated offline on a per-network basis. The upgrade heights will be announced in advance (see [Network upgrades](./participate#network-upgrades)) to give node operators time to download and start a compatible binary prior to the upgrade height.

 - If you are a consensus node or validator operator: you will need to download and run a celestia-app binary >= v2.0.0 prior to the `--v2-upgrade-height` to remain on the canonical chain. You do not need to use a tool like [cosmovisor](https://docs.cosmos.network/main/build/tooling/cosmovisor) to upgrade the binary at the upgrade height.
 - If you are a DA node operator, you will need to download and run a compatible celestia-node binary >= v0.16.0-rc0 prior to the upgrade height.
