+#### Importing mainnet/testnet dump files
+
+If you want to jump-start your mainnet or testnet node with [chain archives
+provided by NGD](https://sync.ngd.network/) follow these instructions:
+```
+$ wget .../chain.acc.zip # chain dump file
+$ unzip chain.acc.zip
+$ ./bin/neo-go db restore -m -i chain.acc # for testnet use '-t' flag instead of '-m'
+```
+
+The process differs from the C# node in that block importing is a separate
+mode, after it ends the node can be started normally.

+## Smart contract development

+workshop](https://github.com/nspcc-dev/neo-go-sc-wrkshp) that shows some
+simple contracts that can be compiled/deployed/run using neo-go compiler, SDK
+and private network.
