+# Daniil Gentili entry
+
+This is my entry for the TON contest.
+
+## Building
+
+Simply run the build.sh script to automatically build tonlib and set up some simplified wrapper scripts.
+
+```
+toolchain/build.sh
+```
+
+This will automatically build the lite client, fift and func, and will also edit .bashrc to add some wrapper scripts to the PATH.
+
+* `lite-client` runs the lite client, already preconfigured to connect to the testnet, with db path set to $TONLIB_HOME/../ton-db-dir (aka this repo/ton-db-dir).
+* `funcompile` is a wrapper for the `func` compiler, automatically including the stdlib while compiling.
+* `fift` is a simple wrapper for the fift compiler.
