+## Generate CHT/BloomTrie:
+1. Clone https://github.com/ethereum/go-ethereum
+2. Run `make`
+3. Run full node: `build/bin/geth --testnet --syncmode "full" --lightserv 90 --cache 512 console`
+4. Wait until it synchronizes (if unsure, check the latest block number with http://ropsten.etherscan.io for example)
+5. Find two log lines starting with **"Storing CHT"** and **"Storing BloomTrie"**.
+Example output:
+```
+INFO [01-16|13:37:34] Storing CHT                              idx=71 sectionHead=196bbde833b65a00668ebfd41e2250252ca341b43f33719637ff9b7b0c6fb6c7 root=4d3108bf5334e1eee0d0940b43b69f532012640961f658cf5e42930dbebefba9

+```
+6. Write down 4 values (example, based on output above):
+* Section Index: **71** (`idx=`)
+* Section Head: **196bbde833b65a00668ebfd41e2250252ca341b43f33719637ff9b7b0c6fb6c7** (`sectionHead=`)
+* CHT Root: **4d3108bf5334e1eee0d0940b43b69f532012640961f658cf5e42930dbebefba9** (`root=` from the "Storing CHT" line)
+* BloomTrie Root: **dcd1f171503b19970b37a851498c1eeac4744bfb26df9d67ab360818f3d37ba4** (`root=` from the "Storing BloomTrie" line)
