 `memory_store` illustrates how to make a custom storage plugin for remark42. 
 
+In order to run remark42 with memory_store copy provided `compose-dev-memstore.yml` to the root directory and run:
+
+1. docker-compose -f compose-dev-memstore.yml build
+1. docker-compose -f compose-dev-memstore.yml up
+
+As usual, demo site will run on http://127.0.0.1:8080/web/
+
+note: in order to work with the latest (current) version of master `go.mod` uses replacement directive for the backend package
+. In real-life usage `replace github.com/umputun/remark/backend => ../../`  should not be used.
