64 | | -# 📦 Get Started |
65 | | - |
66 | | -You can install Langflow with pip: |
67 | | - |
68 | | -```shell |
69 | | -# Make sure you have >=Python 3.10 installed on your system. |
70 | | -python -m pip install langflow -U |
71 | | -``` |
72 | | -Or |
73 | | - |
74 | | -If you would like to install from your cloned repo, you can build and install Langflow's frontend and backend with: |
75 | | - |
76 | | -```shell |
77 | | -make install_frontend && make build_frontend && make install_backend |
78 | | -``` |
79 | | - |
80 | | -Then, run Langflow with: |
81 | | - |
82 | | -```shell |
83 | | -python -m langflow run |
84 | | -``` |
85 | | - |
86 | | -# 🎨 Create Flows |
87 | | - |
88 | | -Creating flows with Langflow is easy. Simply drag components from the sidebar onto the workspace and connect them to start building your application. |
89 | | - |
90 | | -Explore by editing prompt parameters, grouping components into a single high-level component, and building your own Custom Components. |
91 | | - |
92 | | -Once you’re done, you can export your flow as a JSON file. |
93 | | - |
94 | | -Load the flow with: |
95 | | - |
96 | | -```python |
97 | | -from langflow.load import run_flow_from_json |
98 | | - |
99 | | -results = run_flow_from_json("path/to/flow.json", input_value="Hello, World!") |
100 | | -``` |

168 | | - |
169 | | -These parameters are important for users who need to customize the behavior of Langflow, especially in development or specialized deployment scenarios. |
170 | | - |
171 | | -### Environment Variables |
172 | | - |
173 | | -You can configure many of the CLI options using environment variables. These can be exported in your operating system or added to a `.env` file and loaded using the `--env-file` option. |
174 | | - |
175 | | -A sample `.env` file named `.env.example` is included with the project. Copy this file to a new file named `.env` and replace the example values with your actual settings. If you're setting values in both your OS and the `.env` file, the `.env` settings will take precedence. |
