 Installation
 ------------
 
 The easiest way to install this module is from the python package index using pip::
     
-    pip install hg+https://repositories.imaa.cnr.it/public/scc_access/#egg=scc-access
+    pip install hg+https://repositories.imaa.cnr.it/public/scc_access#egg=scc-access
+
+or, if you don't have mercurial on your system::
+
+   pip install https://repositories.imaa.cnr.it/public/scc_access/archive/tip.zip
 
 You can also use the script by cloning this mercurial repository.
 
-
 Settings
 --------
-You will need to provide some user-defined settings in a .yaml format. You
-can rename the config_sample.yaml file to e.g. config.yaml and follow the instructions
-inside the file.
+The required user-defined settings need to be specified in a .yaml file.
 
-Specifically, you will need to:
+The following parameters should be specified::
 
-1. Change the BASIC_LOGIN and DJANGO_LOGIN to your credentials.
-2. Change the OUTPUT_DIR to the location were the results will be stored.
+   basic_credentials: ['username', 'password']     # The HTTP user name and password that is needed to access the SCC site.
+   website_credentials: ['username', 'password']   # The user name and password that is needed to log in to the SCC site.
+   output_dir: /path/to/files/scc_output/          # The directory to download the files
+   base_url: https://scc.imaa.cnr.it/              # SCC base URL. Normally you shouldn't need to change that.

-Please not that it's not a good idea to store your stations management credentials in the settings

+The repository includes a `settings_sample.yaml` file that you can use as a starting point. Rename the file, e.g. to
+`settings.yaml` and input the required parameters. If you don't want to specify the file path every time
+your run the `scc_access` script, you can name the file `.scc_access.yaml` and place it  in your home directory.
+
+Please note that it's not a good idea to store your stations management credentials in the settings
+file. The standard user has "Station Management" privileges and, if the credentials
 are stolen, someone could change/delete the stations settings from the SCC database.
 For this, it is better to use a user account with minimum access settings, i.e. that
 can only upload files and measurements.

 You can upload a file specifying the username and the system id::
     
-   scc_access ./config.yaml ./20110101po01.nc 125
+   scc_access upload-file 20110101po01.nc 125
 
 If you want to wait for the processing to finish and download the resulting files
-you need to define the -p flag::
+you can use add the `-p` or `--process` flag::
     
-   scc_access ./config.yaml ./20110101po01.nc 125 -p
+   scc_access upload-file 20110101po01.nc 125 -p
 
-If the provieded measurement ID is already registerd on the SCC, the upload will be rejected. You can
-instruct the script to first delete the existing measurement using the --force_upload flag::
+The two command above assume that you have placed your setting file in the default location. You can specify a
+custom location using the -c flag::
 
-   scc_access ./config.yaml ./20110101po01.nc 125 --force_upload -p
+   scc_access -c ./path/to/settings.yaml upload-file 20110101po01.nc 125

+By default, the SCC will reject an uploaded file, if the specified measurement id already exists on the server. You
+can instruct the script to delete any existing measurement before uploading using the `--force_upload` flag::
 
-You can restart the processing chain on a particular measurements using either the --rerun-all or
---rerun-elpp options and specifying an existing measurement ID. E.g::
+   scc_access upload-file 20110101po01.nc 125 -p --force_upload
 
-   scc_access ./config.yaml --rerun-elpp 20110101po02
+If you want to delete an existing measurement id from the database use the `delete`
+command and the measurement id::
+    
+    scc_access delete 20110101po01
 
-If you want to delete an existing measurement from the database use the --delete option and
-the measurement id::
-    
-    scc_access --delete 20110101po01
+You can list available measurements with the `list` command::
+
+    scc_access list
+
+.. note::
+   The `list` command needs to be updated. Cross-check the results before using them.
