 ## Requirements
- * ruby >=2.2
  * rvm
- * Dspace server
- * Postgres >=9.4
- * Elasticsearch
- * Redis
+    * Using rvm you will install ruby "3.0.1"
+ * ruby "3.0.1"
+ * Dspace server "6.x"
+ * Postgres "13"
+ * Elasticsearch "6.8.13"
+ * Redis ">=5.0"
+ * nvm
+    * Using nvm you will install Node.js "14.15.1"
+
+## NVM and Node.js
+
+For install NVM and Node.js, use this follwing commands:
+```
+$ wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.37.0/install.sh | bash
+```
+
+```
+$ nvm install 14.15.1
+``` 
+
+## Postgres
+
+After the first install, you can run this commands:
+
+* ``` sudo passwd postgres ```
+* ``` su postgres```
+* ``` psql -c "ALTER USER postgres WITH PASSWORD '$PASSWORD'" -d template1 ```
+* ``` createuser -h localhost -U postgres -d $USER_DB ```
+* ``` psql -c "ALTER USER $USER_DB WITH PASSWORD '$PASSWORD'" -d template1 ```
+
+Note: You can ask for the database dump for someone in the project.
+
+You need to modify the file "/etc/postgresql/11/main/pg_hba.conf", the modification is
+
+    * comment the 1st and 2nd lines with "peer" and copy them replacing "peer" with "md5".
+    
+After this, run this command:
+
+* ``` systemctl restart postgresql ```
+
+## Rvm
+
+After finish the installer, you will need to add in your ~/.bashrc this commands:
+
+* ``` export PATH="$PATH:$HOME/.rvm/bin" ```
+* ``` source /home/Your_user/.rvm/scripts/rvm ```
+
+After this, run the command ```source ~/.bashrc```.
+
+``` Note ``` : If does not work, you can try modify the commands above, for this:
+
+* ```export PATH="$PATH:/usr/share/rvm/bin" ```
+* ```source /usr/share/rvm/scripts/rvm``` 
+
 
 ## Setup
-First of all, you need configure the dspace, elasticsearch and redis servers. An user for postgres database will be needed to.
-After this setup, open the config files and update some vars:
+First of all, you need to configure the dspace, elasticsearch and redis servers. Create an user for postgres database.
+After this setup, open the configuration files inside the project repository and update the following files:
 
     * config/database.yml: change your postgres credentials for development and test environment.
     * config/dspace.yml: change your dspace host and credentials for development and test environment.
     * config/sidekiq.yml: change your redis hosts and ports.
+    * config/initializers/elasticsearch.rb: inside elsif Rails.env.test? change url 'elasticsearch:9200' to 'localhost:9200'.
     * config/initializers/gitlab.rb: change your gitlab host for bug reports and set env var with private token. ( $ export GITLAB_PORTALMEC_PRIVATE_TOKEN=131237128937128937 )
 
-### Development environment
 
+
+## Install
+After installed the requeriments, the first you will need to do is run:
+
+*   ``` bundle install ```
+
+This command will install all required gems for the project. 
+
+```Note ```: Sometimes some gems throw errors. That is because there is a chance that you do not have all the required dependecies for the installation of the gem that failed to install. Please install the dependencies and try again.
+
+After all gems were installed succesfuly. Please create the database using the following commands:
+*  ``` rake db:create ```
+* If you have the dump of the database, use it before db:migrate.
+    * To use the dump, run this commands:  ```psql -U $DATABASE_USER -d $DATABASE_NAME < $DATABASE_PATH/dump_name.sql ```  
+*  ``` rake db:migrate ```
+
+``` Note ``` : You need to load the dump in the database_dev.
+
+
+This procedure will create and configure all table in the project database  
+
+For the search mechanism to works, execute the CMD in the portalmec directory ``` rake searchkick:reindex:all ```.
+
+
+<!--### Development environment-->
+<!-- Se algum dia o docker do projeto for arrumado, essa parte deve bastar como explicação -->
+<!--
     #### Using docker for development env
-    You can use docker for your development environment. For that, run:
-    ``` ./bin/docker-setup ```
+    You can use docker for your development environment. For that, run: 
+        ./bin/docker-setup 
     Now, redis, elasticsearch and postgres are running as services and linked to PortalMEC application. Database migrations were execute and the configs (database.yml, sidekiq.yml was replaced by config/docker/...).
 
 If all development and test vars are set, run:
-``` ./bin/setup ```
-This command will install the rubygems, create/reset your database schema, seed some default data and import all dspace data.
 
-After this, your application is ready to use and you can access it with:
+
+
+*    ```rake db:create``` 
+
+
+This command will install the rubygems, create/reset your database schema, seed some default data and import all dspace data.-->
+
+Once finished, your application is read to be used. To acess it, run CMD:
 ``` bundle exec rails s ```
 
+<!--
+Se a rotina de testes descrita pelo rake test for arrumada, o comando a baixo funcionara
 ### Running tests suite
-For tests, TestUnit is used, and to run it:
-``` bundle exec rake test ```
+For tests, TestUnit is used, and to run it
+``` bundle exec rake test ```-->
+
+
+For tests, run this commands:
+
+* ``` export DSPACE_LOGIN=your_login ```
+* ``` export DSPACE_PASS=your_password ```
+* ``` source ~/.bashrc ```
+
+* ``` bundle exec rake spec:acceptance ```
 
 ### Production environment
-As you set development and test environment vars, now production vars will be needed to be set.
-For that, open the file config/env_vars.sh and set them. After, run:
-``` ./config/env_vars.sh ```
+When working in the production environment, the environment variables must be set in the file config/env_vars.sh.
+After setting the variables in the file, you must include the following line into your user's .bashrc file:
+* ``` source /home/portalmec/portalmec/config/env_vars.sh ```
 
-    * Redis vars need to be set on config/sidekiq.yml
-    * In config/initializers/devise.rb, change the emails addresses. (Ex.: config.mailer_sender = 'suporte@c3sl.ufpr.br')
+You will also need to make some other configurations:
 
-Now, you can run and your application is ready to use:
-``` ./bin/setup ```
+    * Redis vars need to be set on config/sidekiq.yml
+    * In config/initializers/devise.rb, change the e-mail addresses. (Ex.: config.mailer_sender = 'suporte@suporte.com')
+    * In app/services/learning_object_publisher.rb, in the create_dspace_item change the DSpace collection where the items are gonna be created.
+    * Change the paths in the *.sh and *.service files in the root of the project to the absolute path of the project in the production server.
+    * As root, copy the *.service files to the server's systemd directory (Ex.: /lib/systemd/system), then run systemctl enable portalmec and systemctl enable portalmec-sidekiq.
+    * As root, copy the sidekiq_log.conf file to the rsyslog directory (/etc/rsyslog.d/) and give the shared/logs/sidekiq.log file the same permissions and ownership as the /var/log/syslog file.
 
-After the setup, link your webserver to the app. Some OS services are in root of the project and can be used.
\ No newline at end of file
+Now that your application is ready, you can run it with:
+* ``` systemctl start portalmec portalmec-sidekiq ```
