+### Compile features / use flags
+Different use flags are available for `ffsend` to toggle the compilation of
+various features. The following features are available, some are enabled by
+default:
+
+| Feature     | Enabled | Description                                                |
+| :---------: | :-----: | ---------------------------------------------------------- |
+| `clipboard` | Default | Support for copying links to the clipboard                 |
+| `history`   | Default | Support for tracking files in history                      |
+| `archive`   | Default | Support for archiving and extracting uploads and downloads |
+| `no-color`  |         | Compile without color support in error and help messages   |
+
+To compile with a different set of features, specify them with `--features
+<features, >` when building or installing with `cargo`.
+You may want to disable all default features first using `--no-default-features`.
+Here are some examples:
+
+```bash
+# Defaults with no color, one of
+cargo install --features no-color
+cargo build --release --features no-color
+
+# No features
+cargo install --no-default-features

+# Only history and clipboard support
+cargo install --no-default--features --features history,clipboard
