+The EWS pipeleine is a collection of tools, coordinated via a common framework. The tools are:
+
+**Source calculation:**
+
+Calculates daily spore sources from a host map and surveillance points. Used by the MetOffice for the NAME dispersal calculations
+
+**Deposition:**
+
+Makes use of the NAME dispersal calculations provided by the UK Met Office to plot charts and show spore source locations.
+**note that the Deposition tool does not currently have a separate Gitlab package**, the logic is contained within the
+generic support packages: coordinator, post-processing and plotting.
+
+**Environmental suitability:**
+
+Makes use of UK Met Office weather forecasts to calculate the environmental suitability for Wheat Rust infection to occur.
+
+**Epidemic pressure:**
+
+Simulates infected area of grid cells according to epidmiological formulations and various input data streams, including
+the Source calculation, Deposition and Environmental Suitability tools.
+
+**Advisory:**
+
+Assembles outputs from the other EWS tools to create word documents which can be used as templates for advisories.
+
+The figure below shows the various Gitlab software packages that constitute the tools listed above, and the work flows
+between them.
