# Project Development Overview

Projects are developed by methodology developers, project developers or Earth stewards using methodologies and credit classes from the following: 

* [Regen Registry Library](https://library.regen.network) 
* Methodologies with approval to use from [another registry](https://handbook.regen.network/protocol-development/submitting-a-methodology)
* [Your own methodology](https://handbook.regen.network/protocol-development/protocol-methodology-development-overview) and [credit class ](https://handbook.regen.network/credit-type)

During the project term, changes in ecological state are monitored to track how successfully the methodology was implemented and calculate the number of credits eligible to be sold in the market. 

## Project Development Process

* [Project Registration](https://handbook.regen.network/project-development/project-registration)
  * [Project plan submission](https://handbook.regen.network/project-development/project-registration/project-plan-template) and review
  * Project validation
  * [Monitoring report](https://handbook.regen.network/project-development/monitoring-overview/monitoring-report-and-template) 
* [Project Marketing](https://handbook.regen.network/project-development/project-marketing)
  * [Project page](https://handbook.regen.network/project-development/project-marketing/create-a-project-page) 
* [Credit Issuance ](https://handbook.regen.network/credit-issuance/credit-issuance)
  * Project lifecycle

Once the data is verified credits can be created to list in on [Regen Ledger](https://docs.regen.network/) and sold through the [Regen Marketplace](https://app.regen.network/)

Regen Registry provides support to project developers and Earth stewards throughout the project development process with the following: templates, documentation reviews and open source science tools.
