 # containers-sugar
 
-Simplify the usage of containers
+Simplify the usage of containers.
+
+You may be thinking, why do I need a new library that wrap-up
+docker-compose or podman-compose if they are already really simple to use?
+
+Yes, they are simple to use, but if you have some other parameters to
+the compose command line, it could be very tedious to write them every time
+such as `--env-file`, `--project-name`, `--file`, etc.
+
+So, in this case we could use something like a script or `make`, right?
+
+Yes, and just for one project it would be good enough. But, if you maintain
+or collaborate a bunch of projects, it would be like a boiler plate.
+
+Additionally, if you are maintaining some extra scripts in order to improve
+your containers stack, these scripts would be like a boilerplate as well.
 
+So, the idea of this project is to organize your stack of containers,
+gathering some useful scripts and keeping this information centralized in a
+configuration file. So the command line would be very simple.

 ## Features
 
-* TODO
+The commands from docker-compose available are:
+
+* build
+* config
+* create
+* down
+* events
+* exec
+* images
+* kill
+* logs
+* pause
+* port
+* ps
+* pull
+* push
+* restart
+* rm
+* run
+* start
+* stop
+* top
+* unpause
+* up
+* version
+
+These commands are available in the main profile/plugin, so
+you don't need to specify any extra parameter to access them.
+
+For extra commands, we are gathering them into a profile/plugin called
+`ext`, so you can access them using something like: `sugar ext restart`.
+
+The current available **ext** commands are:
+
+* start -> alias for `up`
+* restart -> runs `stop` and `up`
+
+
+## How to use it
+
+First you need to place the config file `.containers-sugar.yaml` in the root
+of your project. This is an example of a configuration file:
+
+```yaml
+version: 1.0
+compose-app: docker-compose
+default:
+  group: {{ env.ENV }}
+groups:
+  - name: group1
+    project-name: project1
+    compose-path: containers/tests/group1/compose.yaml
+    env-file: .env
+    services:
+      default:
+        - service1
+        - service3
+      available:
+        - name: service1
+        - name: service2
+        - name: service3
+  - name: group2
+    project-name: null
+    compose-path: containers/tests/group2/compose.yaml
+    env-file: .env
+    services:
+      # default: null
+      available:
+        - name: service1
+        - name: service1
+```
+
+**NOTE**: containers-sugar has an convenient alias `sugar` that helps to
+keep the command line shorter, where **k** stands for *containers*,
+**x** stands for *su* (*shu* sound), and **gr** stands for *gar*.
+In another words, you can use `containers-sugar` or `sugar` CLI.
+
+Some examples of how to use it:
+
+* build the defaults services (service1,service3) for group1:
+  `sugar build --group group1`
+
+* build the all services (there is no default service defined) for group2:
+  `sugar build --group group2`
+
+* build all services (ignore default) for group1:
+  `sugar build --group group1 --all`
+
+* start the default services for group1:
+  `sugar ext start --group group1`
+
+* restart all services (ignore defaults) for group1:
+  `sugar ext restart --group group1 --all`
+
+* restart service1 and service2 for group1:
+  `sugar ext restart --group group1 --services service1,service2`
