-
 ## Installation
 
-```bash
-npm install synapse-constants
-```
-
 With Yarn:
 
 ```bash
-yarn add synapse-constants
+yarn add @synapsecns/synapse-constants
 ```
 
-## Usage
-
-
-To restrict the assets and chains that are imported, you can create a "custom bridge list". From the set of all tokens imported from "bridgeable.ts" you can import specific tokens and use that as the custom list you use in your application. The same can be done for chains
+## Build
 
-## Usage
-For maintenance, when new tokens are added to the bridge the following steps should be taken.
+The following command will build the package locally
 
-1. Regenerate bridgeMaps.ts
-
-```bash
-yarn maps:generate
+```
+yarn build
 ```
 
-2. Update Bridgeable.ts with the new token addresses (check all other variables like decimals/ symbols etc. )
+## Usage
 
-3. Repackage and webpack all of the data
+Importing supported tokens and chains:
 
-```bash
-yarn compile
+```js
+import { BRIDGABLE_TOKENS, CHAINS } from '@synapsecns/synapse-constants'
 ```
 
-4. Republish the npm package (make sure to update the version)
+Importing a specific token:
 
-```bash
-npm publish
+```js
+import { USDC } from '@synapsecns/synapse-constants'
 ```
 
+## TODO
 
-TODO:
-- add the basic structure of the token type and the chain type to show accessibility for token logos, chain logos, and any additional information.
