+
+Options Documentation for `gnpy-path-request` and `gnpy-transmission-example`
+=============================================================================
+
+Common options
+--------------
+
+**Option**: `--no-insert-edfas`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Purpose**: Disables the automatic insertion of EDFAs after ROADMs and fibers, as well as the splitting
+of fibers during the auto-design process.
+
+The `--no-insert-edfas` option is a command-line argument available in GNPy that allows users to control the
+automatic insertion of amplifiers during the network design process. This option provides flexibility for
+users who may want to manually manage amplifier placements or who have specific design requirements that
+do not necessitate automatic amplification.
+
+To use the `--no-insert-edfas` option, simply include it in the command line when running your GNPy program. For example:
+
+.. code-block:: shell-session
+
+  gnpy-transmission-example my_network.json --no-insert-edfas
+
+When the `--no-insert-edfas` option is specified:
+
+1. **No Automatic Amplifiers**: The program will not automatically add EDFAs to the network topology after
+   ROADMs or fiber elements. This means that if the network design requires amplification, users must ensure
+   that amplifiers are manually defined in the network topology file. Users should be aware that disabling
+   automatic amplifier insertion may lead to insufficient amplification in the network if not managed properly.
+   It is essential to ensure that the network topology includes the necessary amplifiers to meet performance requirements.
+
+2. **No Fiber Splitting**: The option also prevents the automatic splitting of fibers during the design process.
+   This is particularly useful for users who want to maintain specific fiber lengths or configurations without
+   the program altering them.
+
+
+**Option**: `--equipment`, `-e`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Description**: Specifies the equipment library file.
+
+**Usage**: 
+
+.. code-block:: shell-session
+
+  gnpy-transmission-example my_network.json --equipment <FILE.json>
+
+**Default**: Uses the default equipment configuration in the example-data folder if not specified.
+
+**Functionality**: This option allows users to load a specific equipment configuration that defines the characteristics of the network elements.
+
+**Option**: `--extra-equipment` and `--extra-config`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The `--extra-equipment` and `--extra-config` options allow users to extend the default equipment library and configuration
+settings used by the GNPy program. This feature is particularly useful for users who need to incorporate additional
+equipment types or specific configurations that are not included in the standard equipment library (such as third party pluggables).
+
+**Usage**:
+  
+.. code-block:: shell-session
+
+  --extra-equipment <file1.json> [<file2.json> ...]
+
+**Parameters**:
+
+  - `<file1.json>`: Path to the first additional equipment file.
+  - `<file2.json>`: Path to any subsequent additional equipment files (optional).
+
+**Functionality**:
+
+  - The program will merge the equipment definitions from the specified files into the main equipment library.
+  - If an equipment type defined in the additional files has the same name as one in the main library, the program
+    will issue a warning about the duplicate entry and will include ony the last definition.
+  - This allows for flexibility in defining equipment that may be specific to certain use cases or vendor-specific models.
+
+**`--extra-config`**:
+
+**Description**: This option allows users to specify additional configuration files that can override
+  or extend the default configuration settings used by the program. This is useful for customizing simulation
+  parameters or equipment settings. To set an amplifier with a specific such config, it must be defined in the
+  library with the keyword "default_config_from_json" filled with the file name containing the config in the case of
+  "variable_gain" amplifier or with the "advanced_config_from_json" for the "advanced_model" amplifier.
+
+**Usage**:
+  
+.. code-block:: shell-session
+
+  --extra-config <file1.json> [<file2.json> ...]
+
+**Parameters**:
+  - `<file1.json>`: Path to the first additional configuration file.
+  - `<file2.json>`: Path to any subsequent additional configuration files (optional).
+
+**Functionality**:
+  The program will load the configurations from the specified files and consider them instead of the
+  default configurations for the amplifiers that use the "default_config_from_json" or "advanced_config_from_json" keywords.
+
+Example
+-------
+To run the program with additional equipment and configuration files, you can use the following command:
+
+.. code-block:: shell-session
+
+gnpy-transmission-example --equipment main_equipment.json \
+                          --extra-equipment additional_equipment1.json additional_equipment2.json \
+                          --extra-config additional_config1.json
+
+
+In this example:
+- `main_equipment.json` is the primary equipment file.
+- `additional_equipment1.json` and `additional_equipment2.json` are additional equipment files that will be merged into the main library.
+- `additional_config1.json` is an additional configuration file that will override the default settings for the amplifiers pointing to it.
+
+
+**Option**: `--save-network`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Description**: Saves the final network configuration to a specified JSON file.
+
+**Usage**:
+
+.. code-block:: shell-session
+
+  --save-network <FILE.json>
+
+**Functionality**: This option allows users to save the network state after the simulation, which can be useful for future reference or analysis.
+
+
+**Option**: `--save-network-before-autodesign`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Description**: Dumps the network into a JSON file prior to autodesign.
+
+**Usage**:
+
+.. code-block:: shell-session
+
+  gnpy-path-request my_network.json my_services.json --save-network-before-autodesign <FILE.json>
+
+**Functionality**: This option is useful for users who want to inspect the network configuration before any automatic design adjustments are made.
+
+
+**Option**: `--sim-params`
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Description**: Path to the JSON file containing simulation parameters.
+
+**Usage**:
+
+.. code-block:: shell-session
+
+  gnpy-transmission-example my_network.json --sim-params <FILE.json>
+
+**Functionality**: The `--sim-params` option is a command-line argument available in GNPy that allows users to specify a
+JSON file containing simulation parameters. This option is crucial for customizing the behavior of the simulation:
+the file ``sim_params.json`` contains the tuning parameters used within both the ``gnpy.science_utils.RamanSolver`` and
+the ``gnpy.science_utils.NliSolver`` for the evaluation of the Raman profile and the NLI generation, respectively.
+
+The tuning of the parameters is detailed here: :ref:`json input sim-params<sim-params>`.
+
+
+`gnpy-transmission-example` options
+-----------------------------------
+
+**Option**: `--show-channels`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Description**: Displays the final per-channel OSNR and GSNR summary.
+
+**Usage**: 
+
+.. code-block:: shell-session
+
+  gnpy-transmission-example my_network.json --show-channels
+
+**Functionality**: This option provides a summary of the optical signal-to-noise ratio (OSNR)
+and generalized signal-to-noise ratio (GSNR) for each channel after the simulation.
+
+
+**Option**: `-pl`, `--plot`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Description**: Generates plots of the results.
+
+**Usage**: 
+
+.. code-block:: shell-session
+
+  gnpy-transmission-example my_network.json -pl
+  
+**Functionality**: This option allows users to visualize the results of the simulation through graphical plots.
+
+
+**Option**: `-l`, `--list-nodes`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Description**: Lists all transceiver nodes in the network.
+
+**Usage**: 
+
+.. code-block:: shell-session
+
+  gnpy-transmission-example my_network.json -l
+
+**Functionality**: This option provides a quick way to view all transceiver nodes present in the network topology.
+
+**Option**: `-po`, `--power`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Description**: Specifies the reference channel power in span in dBm.
+
+**Usage**:
+
+.. code-block:: shell-session
+
+  gnpy-transmission-example my_network.json -po <value>
+
+**Functionality**: This option allows users to set the input power level for the reference channel used in the simulation.
+It replaces the value specified in the `SI` section of the equipment library (:ref:`power_dbm<spectral_info>`).
+
+
+**Option**: `--spectrum`
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Description**: Specifies a user-defined mixed rate spectrum JSON file for propagation.
+
+**Usage**:
+
+.. code-block:: shell-session
+
+  gnpy-transmission-example my_network.json --spectrum <FILE.json>
+
+**Functionality**: This option allows users to define a custom spectrum for the simulation, which can
+include varying channel rates and configurations. More details here: :ref:`mixed-rate<mixed-rate>`.
+
+
+Options for `path_requests_run`
+-------------------------------
+
+The `gnpy-path-request` script provides a simple path computation function that supports routing, transceiver mode selection, and spectrum assignment.
+
+It supports include and disjoint constraints for the path computation, but does not provide any optimisation.
+It requires two mandatory arguments: network file and service file (see :ref:`XLS files<excel-service-sheet>` or :ref:`JSON files<legacy-json>`).
+
+The `gnpy-path-request` computes:
+
+  - design network once and propagate the service requests on this design
+  - computes performance of each request defined in the service file independently from each other, considering full load (based on the request settings),
+  - assigns spectrum for each request according to the remaining spectrum, on a first arrived first served basis.
+    Lack of spectrum leads to blocking, but performance estimation is still returned for information.
+
+
+**Option**: `-bi`, `--bidir`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Description**: Indicates that all demands are bidirectional.
+
+**Usage**:
+
+.. code-block:: shell-session
+
+  gnpy-path-request my_network.json my_service.json -e my_equipment.json -bi
+
+**Functionality**: This option allows users to specify that the performance of the service requests should be
+computed in both directions (source to destination and destination to source). This forces the 'bidirectional'
+attribute to true in the service file, possibly affecting feasibility if one direction is not feasible.
+
+
+**Option**: `-o`, `--output`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Description**: Stores computation results requests into a JSON or CSV file.
+
+**Usage**: 
+
+.. code-block:: shell-session
+
+  gnpy-path-request my_network.json my_service.json -o <FILE.json|FILE.csv>
+
+**Functionality**: This option allows users to save the results of the path requests into a specified output file
+for further analysis.
+
+
+**Option**: `--redesign-per-request`
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+**Description**: Redesigns the network for each request using the request as the reference channel
+(replaces the `SI` section of the equipment library with the request specifications).
+
+**Usage**:
+.. code-block:: shell-session
+
+  gnpy-path-request my_network.json my_services.json --redesign-per-request
+
+**Functionality**: This option enables checking different scenarios for design.

 Each release introduces some changes and new features.

 (prepare text for next release)
+**Important Changes:**
+
+The default values for EDFA configuration, including frequency range, gain ripple, noise figure ripple, or dynamic gain tilt
+are now hardcoded in parameters.py and are no longer read from the default_edfa_config.json file (the file has been removed).
+However, users can define their own custom parameters using the default_config_from_json variable, which should be populated with a file name containing the desired parameter description. This applies to both variable_gain and fixed_gain amplifier types.
+
+This change streamlines the configuration process but requires users to explicitly set parameters through the new
+model if the default values do not suit their needs.

-1. Equipment description
-########################
-
-Equipment description defines equipment types and those parameters.
-Description is made in JSON file with predefined structure. By default
-**gnpy-transmission-example** uses **eqpt_config.json** file and that
-can be changed with **-e** or **--equipment** command line parameter.
-Parsing of JSON file is made with
-**gnpy.core.equipment.load_equipment(equipment_description)** and return
-value is a dictionary of format **dict[‘equipment
-type’][‘subtype’]=object**
-
-1.1. Structure definition

-
-
-Array of parameters is a list of objects with unordered parameter name
-and its value definition. In case of multiple equipment subtypes each
-object contains **"type_variety":”type name”** name:value combination,
-if only one subtype exists **"type_variety"** name is not mandatory and
-it will be marked with **”default”** value.

-RamanFiber element
-******************
-
-A special variant of the regular ``Fiber`` where the simulation engine accounts for the Raman effect.
-The newly added parameters are nested in the ``raman_efficiency`` dictionary.
-Its shape corresponds to typical properties of silica.
-More details are available from :cite:`curri_merit_2016`.
-
-The ``cr`` property is the normailzed Raman efficiency, so it is is (almost) independent of the fiber type, while the coefficient actually giving Raman gain is g_R=C_R/Aeff.
-
-The ``frequency_offset`` represents the spectral difference between the pumping photon and the one receiving energy.
