 ### Release solc-js
 - [ ] Wait until solc-bin was properly deployed. You can test this via remix - a test run through remix is advisable anyway.
 - [ ] Increment the version number, create a pull request for that, merge it after tests succeeded.

-Binary packages of Solidity are available at
-`solidity/releases <https://github.com/argotorg/solidity/releases>`_.
+Standalone binaries of the compiler that should run on most distributions without any additional
+installation steps are available on the

-The nightly version can be installed using these commands:
