+# Edge Specs
+
+This folder contains the specifications for the two current edge APIs: client, management. 
+
+## Updating a Spec
+
+If a spec has a bug and you are changing a spec please do not change these files. These 
+files are generated and should not be modified.:
+
+* ./management.yml
+* ./client.yml
+
+The actual specs to modify are located in the `./source/` folder
+
+## Updating Client/Server Stubs
+
+After modifying a file, you will need to regenerate the stub code.
+
+* Download/install `swagger` from https://github.com/go-swagger/go-swagger/releases
+* cd to the directory containing this README
+* issue either:
+** `./scripts/generate_rest.sh`
+** `powershell -file "./scripts/generate_rest.ps1"`
