+### Using a generated .env file
+
+If you're using a centralized secret store, like 1Password, you can create `.env.erb` as a template which looks up the secrets. Example of a .env.erb file:
+
+```erb
+<% if (session_token = `op signin --account my-one-password-account --raw`.strip) != "" %># Generated by mrsk envify
+GITHUB_TOKEN=<%= `gh config get -h github.com oauth_token`.strip %>
+MRSK_REGISTRY_PASSWORD=<%= `op read "op://Vault/Docker Hub/password" -n --session  #{session_token}` %>
+RAILS_MASTER_KEY=<%= `op read "op://Vault/My App/RAILS_MASTER_SECRET" -n --session #{session_token}` %>
+MYSQL_ROOT_PASSWORD=<%= `op read "op://Vault/My App/MYSQL_ROOT_PASSWORD" -n --session #{session_token}` %>
+<% else raise ArgumentError, "Session token missing" end %>
+```
+
+This template can safely be checked into git. Then everyone deploying the app can run `mrsk envify` when they setup the app for the first time or passwords change to get the correct `.env` file.
+
+If you need separate env variables for different destinations, you can set them with `.env.destination.erb` for the template, which will generate `.env.staging` when run with `mrsk envify -d staging`.

 ## Commands
 
-### Running remote execution and runners
+### Running commands on servers
 
-If you need to execute commands inside the Rails containers, you can use `mrsk app exec` and `mrsk app runner`. Examples:

-### Running a Rails console
+### Running interactive commands over SSH
+
+You can run interactive commands, like a Rails console or a bash session, on a server (default is primary, use `--hosts` to connect to another):
+
+```bash
+# Starts a bash session in a new container made from the most recent app image
+mrsk app exec -i bash
+
+# Starts a bash session in the currently running container for the app
+mrsk app exec -i --reuse bash
+
+# Starts a Rails console in a new container made from the most recent app image
+mrsk app exec -i 'bin/rails console'
+```
 
-If you need to interact with the production console for the app, you can use `mrsk app console`, which will start a Rails console session on the primary host. You can start the console on a different host using `mrsk app console --host 192.168.0.2`. Be mindful that this is a live wire! Any changes made to the production database will take effect immeditately.
