This is probably of limited interest to most users, but it is important for the community developers that work on condenser (the code for Steemit.com). Steemit recently made a lot of changes to the way condenser is built and run. When I recently went to make a change to the site, I found that I could no longer install/run a local instance of condenser.
I opened GitHub issue 1609 and 
yarn instead of npm. It turns out the instructions to install and run condenser were out of date, since they still used npm.
I spent the afternoon learning about yarn and figuring out how to get everything working with the new tool. After I was able to get a local instance up and running, I went back and updated the readme to have the correct installation instructions.
I submitted pull request 1629 with all the changes:
https://github.com/steemit/condenser/pull/1629
If the pull request is accepted, then the readme instructions in GitHub will have the correct instructions so that other community developers can install and run a local instance of condenser.
The PR is not accepted yet, but I plan to work with Steemit, Inc. to make any edits necessary to get it approved.
