 ## Methodology v1.0.0
 
+Symbiotic is a shared security protocol that serves as a thin coordination layer, empowering network builders to control and adapt their own (re)staking implementation in a permissionless manner.

+
 ## Metrics
 
 ### Usage and Transactions
 
+- Collateral tokens are minted by users with assets or positions they seek to restake. Collateral tokens are then deposited into vaults, which delegate collateral to operators across Symbiotic networks.
+- The user can claim the withdrawal when the EPOCH + 1 ends. Hence, a withdrawal delay varies from EPOCH + 1 to 2⋅EPOCH. Such funds are immediately reduced from the active balance of the vault.
+
 ### TVL
 
+Total collateral tokens minted.
+
 ### Fees and Revenue
 
+Currently the protocol does not charge a fee, and makes no revenue.
