@@ -18,7 +18,23 @@ To use `mlua_serde`, first add this to your `Cargo.toml`:
 
 ```toml
 [dependencies]
-mlua_serde = "0.4"
+mlua_serde = { version = "0.5", features = ["lua53"] }
+```
+
+You must choose between Lua 5.3 and Lua 5.4. To use Lua 5.4, change `lua53` for
+`lua54` like this:
+
+```toml
+[dependencies]
+mlua_serde = { version = "0.5", features = ["lua54"] }
+```
+
+If you don't have lua installed on your system for some reason, use the `vendored`
+feature:
+
+```toml
+[dependencies]
+mlua_serde = { version = "0.5", features = ["lua53", "vendored"] }
 ```
 
 Next, you can use `to_value`/`from_value` functions to serialize/deserialize:
