+## Week 33
+
+### [Feat: Document shared variables](https://github.com/Kong/docs.konghq.com/pull/7750) (2024-08-13)
+
+Update the template documentation to add details for using shared variables: 
+https://docs.konghq.com/gateway/latest/plugin-development/pdk/kong.ctx/#kongctxshared
+
+
+This looks to have been added here, https://github.com/Kong/kong-plugin-request-transformer/pull/7, but we lack documentation on how to reference it. Using the documented convention, kong.ctx.shared.foo,  results in errors with "kong" being a nil value.
+
+Tests have shown it successful  using this with the request transformer plugin and route transformer advanced, i.e:
+
+x-name:$((function()     return shared["gruber"] end)())
+
+Where "gruber" has been previously defined as
+kong.ctx.shared.gruber = "myHeader"
