 averaged the results. If you want to reproduce our results, then please remember 
 to follow our procedure. 
 
+To run the code you just have to use the `main.py` script, passing the proper
+arguments. The needed arguments for running the `main.py` script are: 
+
+ * The name of the model that will be used, `-m`. Accepted values are:
+ 1. `baseline` -- This is the baseline, CRNN model.
+ 2. `baseline_dilated` -- This is the baseline model, but with the RNN replaced
+ by a CNN with dilated convolution.
+ 3. `dessed` -- This is the baseline model, but with the CNNs replaced by
+ depth-wise separable convolutions.
+ 4. `dessed_dilated` -- This is our proposed model, with depth-wise separable
+ convolutions, followed by dilated convolution. 
+ * The name of the settings file to be used (without the extension `.yaml`): `-c`. For
+ example, if the settings file `synthetic_2016_k_55_d_1_1.yaml` is to be used, then
+ this argument has be `synthetic_2016_k_55_d_1_1`. 
+
+There are some optional arguments for the `main.py` script. These are: 
+
+ * The extension of the settings file, `-e`. Default value is `.yaml`.
+ * The directory where the settings file is ,`-d`. Default value is
+ `settings`.

 Enjoy!
