+# Elys Lending library
+
+The **Valence Elys Lending** library enables lending on Elys from a **input account**. Also, the library allows **withdrawing lent assets** from the **input account** on Elys and depositing the withdrawed tokens into an **output account**. Additionally, users can **claim rewards** from the **input account**, and the rewards will also be sent to the **output account** upon claiming them.
+
+## Configuration
+
+The library is configured on instantiation via the `LibraryConfig` type.
+
+```rust
+pub struct LibraryConfig {
+    /// Address of the input account
+    pub input_addr: LibraryAccountType,
+    /// Address of the output account
+    pub output_addr: LibraryAccountType,
+    /// ID of the pool we are going to lend to
+    pub pool_id: Uint64,
+}
+```
