+
+If you want to use Orchestra you need to install from pip like this:
+```
+pip3 install http://git.io/django-orchestra-dev
+```
+
+But if you want develop orquestra you need to do this:
+```
+git clone https://github.com/ribaguifi/django-orchestra
+pip install -e django-orchestra
+```
+
+# Database
+For default use sqlite3 if you want to use postgresql you need install this packages:
+
+```
+psycopg2 postgresql
+```
+
+You can use it for debian or ubuntu:
+
+```
+sudo apt-get install python3-psycopg2 postgresql-contrib
+```
+
+Remember create a database for your project and give permitions for the correct user like this:
+
+```
+psql -U postgres
+psql (12.4)
+Digite «help» para obtener ayuda.
+
+postgres=# CREATE database orchesta;
+postgres=# CREATE USER orchesta WITH PASSWORD 'orquesta';
+postgres=# GRANT ALL PRIVILEGES ON DATABASE orchesta TO orchesta;
+```
+
+# Create new project
+You can use orchestra-admin for create your new project
+```
+orchestra-admin startproject <project_name> # e.g. panel
+cd <project_name>
+```
+
+Next we need change the settings.py for configure the correct database
+
+In settings.py we need change the DATABASE section like this:
+
+```
+DATABASES = {
+    'default': {
+        'ENGINE': 'django.db.backends.postgresql_psycopg2',
+        'NAME': 'orchestra'
+	'USER': 'orchestra',
+        'PASSWORD': 'orchestra',
+        'HOST': 'localhost',
+        'PORT': '5432',
+        'CONN_MAX_AGE': 60*10
+    }
+}
+```
+
+For end you need to do the migrations:
+
+```
+python3 manage.py migrate
+```
