+# Kairos deposit contract
+A deposit contract for the Kairos L2, targeting Casper Node v2.0 and VM v1.0
+
+# Entry Points
+Documentation of all contract entry points
+
+## Update Admin - ADMIN
+Updates the admin account. Admin account is permitted to re-create the contract purse and to execute withdrawals.
+
+Arguments:
+
+- new_admin: Key
+
+Return:
+
+()
+
+## Create Purse - ADMIN
+Create a new contract purse => overrides the value under the corresponding contract purse named_key
+
+Arguments: 
+
+None
+
+Return:
+
+()
+
+## Get Purse
+Retrieve a reference to the deposit purse with "ADD" permission
+
+Arguments:
+
+None
+
+Return:
+
+URef
+
+## Deposit
+Execute a deposit on the L1.
+
+Arguments:
+
+- temp_purse: URef
+- amount: U512
+
+Return:
+
+()
+
+## Withdrawal - ADMIN
+Withdrawal from the contract purse, can only be called by the admin.
+
+Arguments:
+
+- destination_purse: URef
+- amount: U512
+
+Return:
+
+()
+
+## Increment most recent Deposit Counter - ADMIN
+This entry point is called by the L2 whenever a deposit request is routed through the L2 (not created through a native L1 call). This method updates the counter of the total deposits submitted through both L1 and L2.
+
+Arguments:
+
+None
+
+Return: 
+
+()
+
+# User 
+    
+    -> main_purse
+
+    -> temp_purse
+
+1. Call the session code to transfer N tokens from main_purse to the freshly created temp_purse.
+
+2. The session code will then call the deposit entry point of the deposit contract and pass the temp_purse as a reference.
+
+3. All funds from the temp_purse will be transferred to the contract_purse that is managed by the ADMIN.
+
+
+## Building and testing
+Currently the paths in build-macos-darwin.sh are configured for Macos, nixifying this makes sense. Paths must be discoverable by utils.rs in the test engine.
+
+For now, on Macos:
+
+`./build-macos-darwin-feat-2.0.sh`
+
+or, on Ubuntu/Debian:
+
+`./build-ubuntu-feat-2.0.sh`
+
+next, set the environment variable that points to the compiled .wasm binaries (contracts and sessions):
+
+```bash
+chef@chef:~/Kairos/kairos-cctl-env/kairos$ export PATH_TO_WASM_BINARIES="/home/chef/Kairos/kairos-cctl-env/kairos/kairos-deposit-contract/target/wasm32-unknown-unknown/release"
+```
+
+then:
+
+```bash
+# navigate to the root 
+cd kairos
+# run the contract-specific tests
+cargo test -p kairos-deposit-contract-tests
+```
