+If you want to make changes to the code, you can build from source, and run the API.
+
+## Build Dependencies
+
+* cmake
+
+### Debian / Ubuntu
+
+```sh
+sudo apt-get install cmake
+```
+
+### Fedora / RHEL
+
+```sh
+sudo dnf install cmake
+```
+
+## Getting Started
+
+```bash
+git clone https://github.com/LibreTranslate/LibreTranslate.git
+cd LibreTranslate
+pip install -e .
+libretranslate [args]
+
+# Or
+python main.py [args]
+```
+
+Then open a web browser to <http://localhost:5000>
+
+## Run with Docker
+
+Linux/macOS: `./run.sh [args]`
+Windows: `run.bat [args]`
+
+Then open a web browser to <http://localhost:5000>
+
+## Build with Docker
+
+```bash
+docker build -f docker/Dockerfile [--build-arg with_models=true] -t libretranslate .
+```
+
+If you want to run the Docker image in a complete offline environment, you need to add the `--build-arg with_models=true` parameter. Then the language models are downloaded during the build process of the image. Otherwise, these models get downloaded on the first run of the image/container.
+
+Run the built image:
+
+```bash
+docker run -it -p 5000:5000 libretranslate [args]
+```
+
+Or build and run using Docker Compose:
+
+```bash
+docker compose up -d --build
+```
+
+> Feel free to change the [`docker-compose.yml`](https://github.com/LibreTranslate/LibreTranslate/blob/main/docker-compose.yml) file to adapt it to your deployment needs, or use an extra `docker-compose.prod.yml` file for your deployment configuration.
+>
+> The models are stored inside the container under `/home/libretranslate/.local/share` and `/home/libretranslate/.local/cache`. Feel free to use volumes if you do not want to redownload the models when the container is destroyed. To update the models, use the `--update-models` argument.

+## FAQ
+
+### Externally Managed Environment
+
+Some users may encounter the following error while installing packages:
+
+```
+error: externally-managed-environment
+
+× This environment is externally managed
+╰─> To install Python packages system-wide, try apt install
+    python3-xyz, where xyz is the package you are trying to
+    install.
+
+    …
+```
+
+This occurs when your operating system depends on and manages Python for core functionality. In this case, you should install and setup venv (virtual environments) to manage project dependencies.
+
+This prevents pip packages from being installed system-wide. This way, there are no risks of pip packages conflicting between multiple projects or the operating system.
