-
 ```sh
-npm i capi https://capi.dev/frame/wss/rpc.polkadot.io/@latest/pkg.tar
+npm i capi
 ```

 {
   "imports": {
-    "@capi/polkadot": "https://capi.dev/frame/wss/rpc.polkadot.io/@latest/"
+    "capi": "https://deno.land/x/capi/mod.ts"
   }
 }
 ```
 
+</details>
+
+## Configuration
+
+Create a `capi.config.ts` and specify the chains with which you'd like to
+interact.
+
+```ts
+import { CapiConfig } from "capi"
+
+export const config: CapiConfig = {
+  server: "https://capi.dev/",
+  chains: {
+    polkadot: {
+      url: "wss://rpc.polkadot.io/",
+      version: "v0.9.40",
+    },
+  },
+}
+```
+
+Let's also configure an ephemeral development network.
+
+```diff
+- import { CapiConfig } from "capi"
++ import { binary, CapiConfig } from "capi"
+
+export const config: CapiConfig = {
+  server: "https://capi.dev/",
+  chains: {
+    polkadot: {
+      url: "wss://rpc.polkadot.io/",
+      version: "v0.9.40",
+    },
++   polkadotDev: {
++     binary: binary("polkadot", "v0.9.38"),
++     chain: "polkadot-dev",
++   },
+  },
+}
+```
+
+## Command Line Tool
+
+In this documentation, we use Capi's CLI via the alias "capi", instead of via
+its full path:
+
+```sh
+./node_modules/.bin/capi
+```
+
+<details >

+
+```sh

+```
+
+</details>
+
+## Codegen Chain-specific APIs
+
+```sh
+capi sync --package-json package.json
+```
+

+
+```sh
+capi sync --import-map import_map.json
+```
+

+
 ## At a Glance
 
+Retrieve the first 10 entries from a storage map of Polkadot.
+
 ```ts
-import { System } from "@capi/polkadot"
+import { chain } from "@capi/polkadot"
 
-const accounts = await System.Account.entryPage(10, null).run()
+const accounts = await chain.System.Account
+  .entryPage(10, null)
+  .run()
 ```
 
+## Development Networks
+
+To run this same example against the Polkadot development network, use the
+`serve` command, followed by a `--` and your devnet-using command.
+
+```sh
+capi serve -- <your-command>
+```
+
+> For examples...
+>
+> - `capi serve -- npm run start`
+> - `capi serve -- node ./main.js`
+> - `capi serve -- deno run -A ./main.ts`
+
