-# LangChain Tracing Instructions
+# Tracing
+
+By enabling tracing in your LangChain runs, you’ll be able to more effectively visualize, step through, and debug your chains and agents.
 
 First, you should install tracing and set up your environment properly.
 You can use either a locally hosted version of this (uses Docker) or a cloud hosted version (in closed alpha).
+If you're interested in using the hosted platform, please fill out the form [here](https://forms.gle/tRCEMSeopZf6TE3b6).

 # Cloud Hosted Setup
 
-We offer a hosted version of tracing at https://langchainplus.vercel.app/. You can use this to view traces from your run without having to run the server locally.
+We offer a hosted version of tracing at [langchainplus.vercel.app](https://langchainplus.vercel.app/). You can use this to view traces from your run without having to run the server locally.
 
 Note: we are currently only offering this to a limited number of users. The hosted platform is VERY alpha, in active development, and data might be dropped at any time. Don't depend on data being persisted in the system long term and don't log traces that may contain sensitive information. If you're interested in using the hosted platform, please fill out the form [here](https://forms.gle/tRCEMSeopZf6TE3b6).
