+#+TITLE: :lang solidity
+
+This module adds [[https://github.com/ethereum/solidity][Solidity]] support through [[https://github.com/ethereum/emacs-solidity][solidity-mode]]
+
++ Syntax-checking (~flycheck~)
++ Code completion (~[[https://github.com/ssmolkin1/company-solidity][company-solidity]]~)
++ Gas estimation(~C-c C-g~)
+  
+* Install
+There are two options for linters.
+
+** [[https://github.com/ethereum/solc-js][Solc]]
+#+BEGIN_SRC sh
+npm install -g solc
+#+END_SRC
+
+** [[http://solium.readthedocs.io/en/latest/user-guide.html#installation][Solium]]
+#+BEGIN_SRC sh
+npm install -g solium
+#+END_SRC
+
+By default *solium* looks for ~.soliumrc.json~ in the project directory, but you can set it to your own ~.soliumrc.json~ with this in your private doom ~config.el~
+
+#+BEGIN_SRC emacs-lisp
+(setq flycheck-solidity-solium-soliumrcfile "/$HOME/.soliumrc.json")
+#+END_SRC
+
+They can be chained together so it's recommended you use both. *Solc* is ran first, and then *Solium* if *Solc* doesn't catch any errors.
+
+* TODO
