+Optional Features
+-----------------
+
+The Discord and Matrix functions pull some further dependencies, which are not needed for a basic usage.
+Therefore, those features are optional and must be enabled by hand if you wish to use either the Discord integration or the Matrix integration!
+To do so, simply adjust your cargo command by adding `--features`:
+
+```sh
+# Discord
+cargo build --release --features "im-discord"
+# Matrix
+cargo build --release --features "im-matrix"
+# Both
+cargo build --release --features "im-matrix im-discord"
+```
