 ## Development ##
 
-Most of the main operations can be done through the helper script
-`manage.sh`.
+### Introduction ###
 
-The development requires of UXBOX is done through a single docker
-container. Each main service is opened in a different
-[tmux](https://github.com/tmux/tmux) sessions.
+The development environment consists in a docker container that mounts
+your local copy of the uxbox souce code directory tree and executes a
+tmux inside the container in order to facilitate execute multiple
+processes inside.
 
 
-## Docker
+### System requirements ###
+
+You should have `docker` installed in your system in order to set up
+properly the uxbox development enviroment.
+
+In debian like linux distributions you can install it executing:
+
+```bash
+sudo apt-get install docker
+```
+
+
+### Start the docker container ###
+
+**Requires a minimum knowledge of tmux usage in order to use that
+development environment.**
+
+For start it, staying in this repository, execute:
+
+```bash
+./manage.sh run-devenv
+```
+
+This will do the following:
+
+- Build the image if it is not done before.
+- Download all repositories if them are not downloaded previously.
+- Start a container with predefined tmux layout.
+- Start all needed processes such as gulp and figwheel.
+
+
+### First steps with tmux ###
+
+Now having the the container running and tmux open inside the
+container, you are free to execute any commands and open many shells
+as you want.
+
+You can create a new shell just pressing the **Ctr+b c** shortcut. And
+**Ctrl+b w** for switch between windows, **Ctrl+b &** for kill the
+current window.
+
+
+### Inside the tmux session ###
+
+#### UI ####
+
+The UI related tasks starts automatically so you do not need do anything. The
+**window 0** and **window 1** are used for the UI related environment.
+
+
+#### Backend ####
+
+The backend related environment is located in the **window 2**, and you can go
+directly to it using `ctrl+b 2` shortcut.
+
+By default this tasks are performed:
+
+- Start postgresql.
+- Load initial fixtures into the database.
+
+The repl should be started automatically, if not, you can execute:
+
+```bash
+clojure -Adev:repl
+```
+
+Then use `(start)` to start all the environment, `(stop)` for stoping
+it and `(reset)` for restart with code reloading. If some exception is
+raised when code is reloaded, just use `(refresh)` in order to finish
+correctly the code swaping and later use `(reset)` again.
+
+
+## Production (Docker)
 
 Docker is also used to build release images for backend and
 frontend. Use the helper script `manage.sh` to build the images.  You
