 ## Usage
 
-At this time, this repo is used to configure an API which scrapes information from each chain and exposes it via graphql.  
-The API can be interacted with via this URL: https://squid.subsquid.io/chaindata/v/v4/graphql
+The files in this repo, `chaindata.json`, `testnets-chaindata.json` and `evm-networks.json` are used to configure a GitHub workflow which scrapes information from each chain and publishes it as a collection of JSON files on GitHub Pages.
+
+The published files can be browsed at this URL: https://talismansociety.github.io/chaindata
 
-As an example, you could use this query to get the name, [genesisHash](## 'the hash of the first block on the chain') and [address type prefix](https://wiki.polkadot.network/docs/learn-account-advanced#address-format) for each chain:
+As an example, you could use this request to get a summary of all chains including the the names, logos, [genesisHashes](## 'the hash of the first block on the chain') and [address type prefixes](https://wiki.polkadot.network/docs/learn-account-advanced#address-format):
 
-```graphql
-query {
-  chains {
-    genesisHash
-    prefix
-    name
-  }
-}
+```ts
+const chainsSummaryUrl = "https://talismansociety.github.io/chaindata/chains/summary.json"
+const summary = await fetch(chainsSummaryUrl).then(result => result.json())
 ```
 
-For an example of a more advanced use-case, you can check out the [Talisman wallet](https://github.com/TalismanSociety/talisman/blob/898310b3761a7313ffaa5f2f747736dcb24fd455/packages/chaindata-provider-extension/src/graphql.ts) source code.  
+For an example of a more advanced use-case, you can check out the [Talisman wallet](https://github.com/TalismanSociety/talisman) source code.  
 The wallet uses chaindata to populate a database of chains and tokens which is used for features like account balance subscriptions and sending funds.

+
+### To add chain or token logos:
+
+#### Substrate chain logos
+
+1. Identify the chain `id` from `chaindata.json` or `testnets-chaindata.json`
+1. Add your logo (in `svg` format) to `assets/chains/${id}.svg`
+
+#### EVM chain logos
+
+1. Identify the chain `id` from https://chainlist.org  
+   **Use the base-10 id** (e.g. `1`, or `137`), **not** the base-16 id (e.g. `0x1`, or `0x89`)
+1. Add your logo (in `svg` format) to `assets/chains/${id}.svg`
+
+#### Token logos
+
+1. Identify the token symbol (e.g. `KSM`)
+1. Add your logo (in `svg` format) to `assets/tokens/${symbol}.svg`
+
+### To build the github pages endpoint locally:
+
+1. Install [pnpm](pnpm.io)
+1. Clone the repo via  
+   `git clone [email protected]:TalismanSociety/chaindata.git`
+1. Install the deps via  
+   `pnpm install`
+1. Copy `.env.sample` to `.env` and fill in the variables
+1. Run the build via  
+   `pnpm build`
