+# AENS Usage
+
+This guide describes the basic operations on [AENS name](https://github.com/aeternity/protocol/blob/master/AENS.md) using [Aeternity JS SDK](https://github.com/aeternity/aepp-sdk-js)
+
+## Main Flow
+
+  - Pre-claim name (broadcast `pre-claim` transaction with random `salt`)
+      ```js
+      const sdkInstance = await Universal({ ... }) // Init Universal instance
+
+      const name = 'sometube.chain'
+
+      const preclaim = await sdkInstance.aensPreclaim(name, { ttl, fee, nonce })
+      // {
+      //   ...transactionResult,
+      //   salt,
+      //   commitmentId
+      // } 
+      ```
+     >After transaction is included, you have a `300` blocks to broadcast `claim` transaction with
+     the same `salt` and it should be signed with the same private key as `pre-claim`
+
+  - Claim name (broadcast `claim` transaction which include the `salt` of `pre-claim`)  
+      here, we have two possible scenarios:
+       - `Name length` <= 12: start name `auction`
+       - `Name length` > 12: name is claimed without `auction`
+      ```js
+      const salt = preclaim.salt // salt from pre-claim transaction
+      const options = { ttl, fee, nonce, nameFee, onAccount } // optional: overriding default
+
+      // In case of starting the auction `nameFee` will be the starting bid
+      // The minimum `nameFee` will be generated by sdk if is not provided in options
+      const claim = await sdkInstance.aensClaim(name, salt, options)
+
+
+      // In case of auction you may need to place a bid on already started auction
+      // Currently sdk can't generate the `bid fee` automatically
+      // as it's depend on last bid
+      import { computeBidFee, computeAuctionEndBlock } from '@aeternity/aepp-sdk/es/tx/builder/helpers'
+
+      const startFee = claim.nameFee // start bid
+      const increment = 0.05 // 5%
+
+      const nameFee = computeBidFee(name, startFee, increment)
+      const bid = await sdkInstance.aensBid(name, nameFee, options)
+
+      console.log(`BID STARTED AT ${bid.blockHeight} WILL END AT ${computeAuctionEndBlock(name, bid.blockHeight)}`)
+      ```
+       
+  - Update name  
+Using `aens-update` transaction you can update the name `pointers` and extend name `ttl`
+    ```js
+    const options = { ttl, fee, nonce, nameTtl, onAccount } // optional: overriding default
+    const pointersArray = ['ak_asd23dasdas...,', 'ct_asdf34fasdasd...']
+    const nameObject = await sdkInstance.aensQuery(name)
+
+    await sdkInstance.aensUpdate(name, pointersArray, options)
+    // or
+    await nameObject.update(pointersArray, options)
+
+    // Extend pointers of name entry
+    // Let's assume that we have name entry with one pointers: ['ak_2314234']
+    // Only one entry for each type is allowed
+    // that mean that merging will overwrite pointers with the same type
+    await sdkInstance.aensUpdate(name, pointersArray, { extendPointers: true })
+    ```
+
+  - Transfer  
+  Transfer the name `ownership` to another `account`
+     ```js
+    const options = { ttl, fee, nonce, onAccount }
+    const recipientPub = 'ak_asd23dasdas...'
+    const nameObject = await sdkInstance.aensQuery(name)
+
+    await sdkInstance.aensTransfer(name, recipientPub, options)
+    // or
+    await nameObject.transfer(recipientPub, options)
+     ```
+  - Revoke
+  Revoke the name
+     ```js
+      const options = { ttl, fee, nonce, onAccount }
+      const nameObject = await sdkInstance.aensQuery(name)
+
+      await sdkInstance.aensRevoke(name, options)
+      // or
+      await nameObject.revoke(options)
+     ```
