+# Getting help
+
+## Help menus
+
+The `--help` flag can be used to view the help menu for a command, e.g., for `uv`:
+
+```console
+$ uv --help
+```
+
+To view the help menu for a specific command, e.g., for `uv init`:
+
+```console
+$ uv init --help
+```
+
+When using the `--help` flag, uv displays a condensed help menu. To view a longer help menu for a
+command, use `uv help`:
+
+```console
+$ uv help
+```
+
+To view the long help menu for a specific command, e.g., for `uv init`:
+
+```console
+$ uv help init
+```
+
+When using the long help menu, uv will attempt to use `less` or `more` to "page" the output so it is
+not all displayed at once. To exit the pager, press `q`.
+
+## Viewing the version
+
+When seeking help, it's important to determine the version of uv that you're using — sometimes the
+problem is already solved in a newer version.
+
+To check the installed version:
+
+```console
+$ uv version
+```
+
+The following are also valid:
+
+```console
+$ uv --version      # Same output as `uv version`
+$ uv -V             # Will not include the build commit and date
+$ uv pip --version  # Can be used with a subcommand
+```
+
+## Open an issue on GitHub
+
+The [issue tracker](https://github.com/astral-sh/uv/issues) on GitHub is a good place to report bugs
+and request features. Make sure to search for similar issues first, as it is common for someone else
+to encounter the same problem.
+
+## Chat on Discord
+
+Astral has a [Discord server](https://discord.com/invite/astral-sh), which is a great place to ask
+questions, learn more about uv, and engage with other community members.
