+# Available software
+
+`available_software.py` is a script that generates an overview of all software modules that are available on an HPC system.
+It also generates a detailed overview per software that includes specific software versions.
+To do this, it generates 3 things:
+1. `json_data.json`: This JSON file is used to populate the global overview table.
+2. `json_data_detail.json`: This JSON file is used to automatically generate all the detailed markdown pages.
+3. A lot of MarkDown files: These are the detailed overview pages per software.
+
+The generated files will be placed in the [available_software](/docs/available_software) directory,
+more specifically the [data](/docs/available_software/data) 
+and [detail](/docs/available_software/detail) subdirectories.
+
+## Requirements
+- Required Python packages are listed in `requirements.txt` and `requirements_tests.txt`
+- [Lmod](https://github.com/TACC/Lmod) must be available, and `$LMOD_CMD` must specify the path to the `lmod` binary.
+
+
+### Creating a virtual environment (optional)
+
+If the required Python packages are not available in your Python setup,
+you can easily create a dedicated virtual environment as follows:
+
+```shell
+python -m venv module_overview_venv
+source module_overview_venv/bin/activate
+pip install -r requirements.txt
+pip install -r requirements_tests.txt
+# to exit the virtual environment, run 'deactivate'
+```
+
+## Usage
+You can run the script with following command:
+
+```shell
+python available_software.py
+```
+
+## Testing
+You can run the tests by running the `test.sh` script.
+```shell
+./test.sh
+```
+
+The tests make use of a mocked `$LMOD_CMD` script, which you can find [here](tests/data/lmod_mock.sh).
+
+### Write tests
+If you want to write additional tests and use the script effectively, follow these guidelines:
+
+
+1. **Setting up mocked Lmod:**
+
+   Before each test, ensure that you set the path to the script that mocks the `lmod` binary.
+   This can be done within the setup_class function.
+   ```python
+   path = os.path.dirname(os.path.realpath(__file__))
+
+   @classmethod
+   def setup_class(cls):
+       os.environ["LMOD_CMD"] = cls.path + "/data/lmod_mock.sh"
+   ``` 
+
+### Example 
+An example of a possible `setup_class` function is given below.
+```python
+import os
+
+@classmethod
+def setup_class(cls):
+    os.environ["TESTS_PATH"] = cls.path
+    os.environ["LMOD_CMD"] = cls.path + "/data/lmod_mock.sh"
+    os.environ["SHELL"] = cls.path + "/data/bash_mock.sh"
+    os.environ["MOCK_FILE_SWAP"] = cls.path + "/data/data_swap_TARGET.txt"
+    os.environ["MOCK_FILE_AVAIL_TARGET"] = cls.path + "/data/data_avail_target_simple.txt"
+    os.environ["MOCK_FILE_AVAIL_TARGET_AMD_INTEL"] = cls.path + "/data/data_avail_target_amd_intel.txt"
+```
+
+This does multiple things:
+1. Set the path of the tests folder in `$TESTS_PATH`
+2. Set the path to the `lmod_mock.sh` script in the environment variable `$LMOD_CMD`
+3. set the path to the `bash_mock.sh` script in the environment variable `$SHELL`
+4. Set the output file for the `module swap` to the `MOCK_FILE_SWAP` variable.
+   For example, `data/data_swap_generic.txt` could be a possible file.
+3. Set the output file for the `module avail` to the `MOCK_FILE_AVAIL_TARGET` variable.
+   The actual output can be found in the `data/data_avail_target_simple.txt` file or `/data/data_avail_target_amd_intel.txt` file.
