 # dynamodump
-Node cli for exporting & importing schema of DynamoDB tables
+Node cli for exporting & importing schema of DynamoDB tables. I didn't find any other node tools for dumping table structure (indexes etc), they all only dump data. Can be used in conjunction with other tools to dump data as well.
+
+## Install
+```
+npm install -g dynamodump
+```
+
+## Examples
+```
+dynamodump export-schema --region=eu-west-1 --table=your-table --file=your-schema-dump
+dynamodump import-schema --region=eu-west-1 --file=your-schema-dump --table=your-table --wait-for-active
+```
