+The TON ecosystem is built around two layers of tools.
+**Production-facing infrastructure** delivers the live services that power interaction with the blockchain.
+**Developer-facing tooling** provides the utilities required to build, test, and deploy those services.
+
+The sections below outline both layers.
+
+## Production-facing infrastructure
+
 Describe the flow of data through
 
-- wallet apps
-- sdks
-- http apis
-- adnl
-- node
+- Wallet apps: full-fledged GUI for writing to blockchain
+- SDKs: libraries for reading/writing to blockchain
+- RPC providers: HTTP APIs used under the hood by sdks for reading/writing to blockchain
+- Blockchain node: collaborates with other nodes in handling reading/writing requests
+- Explorers: full-fledged GUI for reading from blockchain
+- TON Connect: library for user interface for reading/writing to blockchain
+- Network status dashboards: pages to check if ecosystem is healthy
+
+
+## Developer-facing tooling
+
+- Blueprint
+- IDE
+- Testing frameworks
+- AI-assisted tools
+
+
+TMA is lost. Should it be noted here?
