# Getting Started with the Library
The library's primary use case is to provide pre-canned parsers for TextFSM.
## Install the Library
To install the library, please follow the instructions detailed in the [Installation Guide](../admin/install.md).
## Usage
The libraries interface is fairly simple, the only public function is the `parse_output` function.
```python
>>> from ntc_templates.parse import parse_output
>>> vlan_output = (
"VLAN Name Status Ports\n"
"---- -------------------------------- --------- -------------------------------\n"
"1 default active Gi0/1\n"
"10 Management active \n"
"50 VLan50 active Fa0/1, Fa0/2, Fa0/3, Fa0/4, Fa0/5,\n"
" Fa0/6, Fa0/7, Fa0/8\n"
)
>>> vlan_parsed = parse_output(platform="cisco_ios", command="show vlan", data=vlan_output)
>>> vlan_parsed
[
{
'vlan_id': '1',
'name': 'default',
'status': 'active',
'interfaces': ['Gi0/1']
},
{
'vlan_id': '10',
'name': 'Management',
'status': 'active',
'interfaces': []
},
{
'vlan_id': '50',
'name': 'VLan50', 'status': 'active',
'interfaces': ['Fa0/1', 'Fa0/2', 'Fa0/3', 'Fa0/4', 'Fa0/5', 'Fa0/6', 'Fa0/7', 'Fa0/8']
}
]
>>>
```
The rest of the functionality comes from the indiviudal TextFSM templates and the primary index file.
