+# Til (Test instructions language)
+Language to define sets of instructions to simulate Hermez transactions (L1 & L2) with real data.
+
+## Syntax
+### Global
+- Set type definition
+    - Blockchain: generate the transactions that would come from the Hermez smart contract on the blockchain.
+	```
+	Type: Blockchain
+	```
+    - PoolL2: generate the transactions that would come from the Pool of L2Txs
+	```
+	Type: PoolL2
+	```
+
+### Blockchain set of instructions
+Available instructions:
+```go
+Type: Blockchain
+
+// register the TokenID:
+RegisterToken(1)
+
+// deposit of TokenID=1, on the account of tokenID=1 for the user A, of an
+// amount of 50 units
+CreateAccountDeposit(1) A: 50
+
+// create the account of TokenID=1 for the user B, deposit of TokenID=1, on the
+// account of tokenID=1 for the user B, of an amount of 40 units and atomically
+// transfer 10 units to account of tokenID=1 for the user A, paying a fee of 2
+CreateAccountDepositTransfer(1) B-A: 40, 10 (2)
+
+// transaction generated by the Coordinator, create account for user User0 for
+// the TokenID=2, with a deposit of 0
+CreateAccountDepositCoordinator(2) User0
+
+
+// deposit of TokenID=1, at the account A, of 6 units
+Deposit(1) A: 6
+
+// deposit of TokenID=1, on the account of tokenID=1 for the user B, of an
+// amount of 6 units and atomically transfer 10 units to account of tokenID=1 for
+// the user A, paying a fee of 2
+DepositTransfer(1) B-A: 6, 4 (2)
+
+// transfer of TokenID=1, from the account A to B (for that token), of 6 units,
+// paying a fee of 3. Transaction will be a L2Tx
+Transfer(1) A-B: 6 (3)
+
+// exit of TokenID=1, from the account A (for that token), of 5 units.
+// Transaction will be a L2Tx
+Exit(1) A: 5
+
+// force-transfer of TokenID=1, from the account A to B (for that token), of 6
+// units, paying a fee of 3. Transaction will be L1UserTx of ForceTransfer type
+ForceTransfer(1) A-B: 6 (3)
+
+// force-exit of TokenID=1, from the account A (for that token), of 5 units.
+// Transaction will be L1UserTx of ForceExit type
+ForceExit(1) A: 5
+
+// advance one batch, forging without L1UserTxs, only can contain L2Txs and
+// L1CoordinatorTxs
+> batch
+
+// advance one batch, forging with L1UserTxs (and L2Txs and L1CoordinatorTxs)
+> batchL1
+
+// advance an ethereum block
+> block
+```
+
+### PoolL2 set of instructions
+Available instructions:
+```go
+Type: PoolL2
+
+// transfer of TokenID=1, from the account A to B (for that token), of 6 units,
+// paying a fee of 4
+PoolTransfer(1) A-B: 6 (4)
+
+// exit of TokenID=1, from the account A (for that token), of 3 units
+PoolExit(1) A: 3
+```
+
+## Usage
+```go
+// create a new til.Context
+tc := til.NewContext(eth.RollupConstMaxL1UserTx)
+
+// generate Blockchain blocks data from the common.SetBlockcahin0 instructions set
+blocks, err = tc.GenerateBlocks(common.SetBlockchain0)
+assert.Nil(t, err)
+
+// generate PoolL2 transactions data from the common.SetPool0 instructions set
+poolL2Txs, err = tc.GenerateBlocks(common.SetPool0)
+assert.Nil(t, err)
+```
+
+Where `blocks` will contain:
+```go
+// BatchData contains the information of a Batch
+type BatchData struct {
+    L1CoordinatorTxs     []common.L1Tx
+    L2Txs                []common.L2Tx
+    CreatedAccounts []common.Account
+}
+
+// BlockData contains the information of a Block
+type BlockData struct {
+    L1UserTxs        []common.L1Tx
+    Batches          []BatchData
+    RegisteredTokens []common.Token
+}
+```
