## Method 1: Generate business process diagram using English like PiperFlow syntax
This is a sample code to generate a business process diagram using  [PiperFlow](https://github.com/csgoh/processpiper/wiki/Usage-Documentation#syntax) syntax. 
```python
from processpiper.text2diagram import render

input_syntax = """
title: Sample Test Process
colourtheme: BLUEMOUNTAIN
    lane: End User
        (start) as start
        [Enter Keyword] as enter_keyword
        (end) as end
pool: System Search
    lane: Database System
        [Login] as login
        [Search Records] as search_records
        <Result Found?> as result_found
        [Display Result] as display_result
        [Logout] as logout
    lane: Log System
        [Log Error] as log_error

start->login: User \\nAuthenticate
login->enter_keyword: Authenticated
enter_keyword->search_records: Search Criteria
search_records->result_found: Result
result_found->display_result: Yes
display_result->logout->end
result_found->log_error: No
log_error->display_result

footer: Generated by ProcessPiper
"""

render(input_syntax, "my_process_map.png")

```

### Method 2: Generate business process diagram using Python code
This is a sample code to generate a business process diagram using Python code. The code is self-explanatory. The diagram is generated using the default colour theme.

```python
from processpiper import ProcessMap, EventType, ActivityType, GatewayType

with ProcessMap(
    "Sample Test Process", colour_theme="BLUEMOUNTAIN") as my_process_map:
    with my_process_map.add_lane("End User") as lane1:
        start = lane1.add_element("Start", EventType.START)
        enter_keyword = lane1.add_element("Enter Keyword", ActivityType.TASK)

    with my_process_map.add_pool("System Search") as pool1:
        with pool1.add_lane("Database System") as lane2:
            login = lane2.add_element("Login", ActivityType.TASK)
            search_records = lane2.add_element("Search Records", ActivityType.TASK)
            result_found = lane2.add_element("Result Found?", GatewayType.EXCLUSIVE)
            display_result = lane2.add_element("Display Result", ActivityType.TASK)
            logout = lane2.add_element("Logout", ActivityType.TASK)
            end = lane2.add_element("End", EventType.END)

        with pool1.add_lane("Log System") as lane3:
            log_error = lane3.add_element("Log Error", ActivityType.TASK)

    start.connect(login, "User \nAuthenticates").connect(
        enter_keyword, "Authenticated"
    ).connect(search_records, "Search Criteria")
    search_records.connect(result_found, "Result").connect(display_result, "Yes")
    display_result.connect(logout).connect(end)
    result_found.connect(log_error, "No").connect(display_result)

    my_process_map.set_footer("Generated by ProcessPiper")
    my_process_map.draw()
    my_process_map.save("my_process_map.png")
```

The generated diagram is as follows:
