 # Monero Block Explorer
 
-Building a very simple HTTP service to help learn Rust and get more familiar with the ecosystem.
+This was mostly built to practice/learn Rust. It may potentially be useful but for now it implements really basic features that can be offered by other explorers. Simplicity can be a good thing though...
 
 ## Running
 
-```
-git clone https://github.com/lalanza808/monero-blockchain-explorer
-cd monero-blockchain-explorer
-rustup override set nightly
-cargo run
-```
+This is quick-start dev server mode.
+
