 Remove compiled files with `make clean` or `make mr_proper` command.

+## Building Debian package
+
+To build Debian package containing compiled contracts, run `make debpackage`
+command. Package will install compiled contracts `*_contract.nef` and manifest 
+`config.json` with corresponding directories to `/var/lib/neofs/contract` for 
+further usage.
+It will download and build neo-go, if needed.
+
+To clean package-related files, use `make debclean`.

 # Testing
 Smartcontract tests reside in `tests/` directory. To execute test suite
 after applying changes, simply run `make test`.

+FrostFS contract is a contract deployed in FrostFS mainchain.
+
+FrostFS contract is an entry point to FrostFS users. This contract stores all FrostFS
+related GAS, registers new Inner Ring candidates and produces notifications
+to control the sidechain.
+
+While mainchain committee controls the list of Alphabet nodes in native
+RoleManagement contract, FrostFS can't change more than 1\3 keys at a time.
+FrostFS contract contains the actual list of Alphabet nodes in the sidechain.
+
+Network configuration is also stored in FrostFS contract. All changes in
+configuration are mirrored in the sidechain with notifications.
+
+# Contract notifications
+
+Deposit notification. This notification is produced when user transfers native
+GAS to the FrostFS contract address. The same amount of FROSTFS token will be
+minted in Balance contract in the sidechain.

+/*
+FrostFSID contract is a contract deployed in FrostFS sidechain.
+
+FrostFSID contract is used to store connection between an OwnerID and its public keys.
+OwnerID is a 25-byte N3 wallet address that can be produced from a public key.
+It is one-way conversion. In simple cases, FrostFS verifies ownership by checking
+signature and relation between a public key and an OwnerID.
+
+In more complex cases, a user can use public keys unrelated to the OwnerID to maintain
+secure access to the data. FrostFSID contract stores relation between an OwnerID and
+arbitrary public keys. Data owner can bind a public key with its account or unbind it
+by invoking Bind or Unbind methods of FrostFS contract in the mainchain. After that,
+Alphabet nodes produce multisigned AddKey and RemoveKey invocations of FrostFSID
+contract.
+
+# Contract notifications
+
+FrostFSID contract does not produce notifications to process.

-
-NeoFSID contract is used to store connection between an OwnerID and its public keys.
-OwnerID is a 25-byte N3 wallet address that can be produced from a public key.
-It is one-way conversion. In simple cases, NeoFS verifies ownership by checking
-signature and relation between a public key and an OwnerID.
-
-In more complex cases, a user can use public keys unrelated to the OwnerID to maintain
-secure access to the data. NeoFSID contract stores relation between an OwnerID and
-arbitrary public keys. Data owner can bind a public key with its account or unbind it
-by invoking Bind or Unbind methods of NeoFS contract in the mainchain. After that,

-Subnet contract is a contract deployed in NeoFS sidechain.

-
-Contract notifications
