+Some notes for furhter editing...
+
+Initial steps:
+- fill `env_defaults`
+- run `./setup gvc postgres redis rails` to setup infrastructure
+- run `./build` to build and push latest image
+
+env_defaults:
+- need to fill values before any execution of other commands
+
+setup:
+- use to apply yaml templates for the app (and substitute envs in them)
+- templates are in `.controlplane/templates/...`
+- can apply single or multiple templates by name - e.g. `./setup gvc postgres redis`
+
+build:
+- builds CPLN's Dockerfile and pushes it to CPLN repo
+- image name is suffixed by ':latest' for simplicity, no versioning
+- force restart workload after build
+
+entrypoint.sh:
+- waits for postgres and redis to be available
+- runs `rails db:prepare` to create&seed or migrate database
+
+run:
+- analogue of `heroku run` one-off dynos
+- creates a clone of app workload, connects to it, executes whatever and deletes workload
+- opens interactive shell when called w/o args, e.g.: `./run`
+- executes provided command and exists when called with args, e.g.: `./run rails db:migrate:status`
+- limitation: atm, there is no way to exectute command with args from `cpln` cli, so it uses some scripting workarounds
+- limitation: when called as `./run rails c` it will not open interactive shell, but will execute command and timeout. To open as interactive, do 1) `./run` to start bash interactive shell 2) type `rails c` manually
