 # resource-projects-etl
-Extract, Transform and Load processes for rp.org
 
-# Requirements
+This repository contains a library for Extract, Transform and Load processes for ResourceProjects.org.
+
+You can report issues with current transformations, or suggest sources which should be added to this library using the GitHub issue tracker.
+
+
+## Processes
+Each process, located in the **process** folder consists of:
+
+* A README.md file describing the transformation
+* An extract.sh or extract.py file to fetch the file
+* A data/ subfolder where the extracted data is stored
+* A transform.py file which runs the transformations
+* A meta.json file, containing the meta-data which transform.py will use
+
+The output of each process should be written to the /data/ folder, from where it can be loaded onto the ResourceProjects.org platform.
+
+
+
+## Requirements
