 If using `--persist-to` to specify a custom folder with `wrangler dev` you should also add `--persist-to` with the same directory name along with the `--local` flag when running the commands above. For example, to put a custom KV key into a local namespace via the CLI you would run:
 
 ```sh
-npx wrangler kv:key put test 12345 --binding MY_KV_NAMESPACE --local --persist-to worker-local
+npx wrangler kv key put test 12345 --binding MY_KV_NAMESPACE --local --persist-to worker-local
 ```
 
 Running `wrangler kv key put` will create a new key `test` with a value of `12345` on the local namespace specified via the binding `MY_KV_NAMESPACE` in the [Wrangler configuration file](/workers/wrangler/configuration/). This example command sets the local persistence directory to `worker-local` using `--persist-to`, to ensure that the data is created in the correct location. If `--persist-to` was not set, it would create the data in the `.wrangler` folder.

 To begin, you need to understand how to populate your todo list with actual data. To do this, use [Cloudflare Workers KV](/kv/) — a key-value store that you can access inside of your Worker to read and write data.
 
-To get started with KV, set up a namespace. All of your cached data will be stored inside that namespace and, with configuration, you can access that namespace inside the Worker with a predefined variable. Use Wrangler to create a new namespace called `TODOS` with the [`kv:namespace create` command](/workers/wrangler/commands/#kv-namespace-create) and get the associated namespace ID by running the following command in your terminal:

 The associated namespace can be combined with a `--preview` flag to interact with a preview namespace instead of a production namespace. Namespaces can be added to your application by defining them inside your Wrangler configuration. Copy your newly created namespace ID, and in your [Wrangler configuration file](/workers/wrangler/configuration/), define a `kv_namespaces` key to set up your namespace:
