 ## Installation
+
 First, make sure you have [git](http://git-scm.com/) installed, and that it is in your PATH.
-Then, install [bower](http://bower.io/), which may be used to install bundles' dependencies:
-```sh
-npm install -g bower
-```
 
 Once those are installed, you may install nodecg-cli via npm:
+
 ```sh
 npm install -g nodecg-cli
-````
+```
 
-Installing `nodecg-cli` does not install `NodeCG`. 
+Installing `nodecg-cli` does not install `NodeCG`.
 To install an instance of `NodeCG`, use the `setup` command in an empty directory:
+
 ```sh
 mkdir nodecg
 cd nodecg
 nodecg setup
 ```
 
 ## Usage
-* `nodecg setup [version] [--update]`, install a new instance of NodeCG. `version` is a semver range.
-If `version` is not supplied, the latest release will be installed.
-Enable `--update` flag to install over an existing copy of NodeCG.
-* `nodecg start`, start the NodeCG instance in this directory path
-* `nodecg install [repo] [--dev]`, install a bundle by cloning a git repo.
-Can be a GitHub owner/repo pair (`supportclass/lfg-sublistener`) or https git url (`https://github.com/SupportClass/lfg-sublistener.git`).
-If run in a bundle directory with no arguments, installs that bundle's dependencies.
-Enable `--dev` flag to install the bundle's `devDependencies`.
-* `nodecg uninstall <bundle>`, uninstall a bundle
-* `nodecg defaultconfig`, If a bundle has a `configschema.json` present in its root, this command will create a default
-config file at `nodecg/cfg/:bundleName.json` with defaults based on that schema.
-* `nodecg schema-types [dir]`, Generate d.ts TypeScript typedef files from Replicant schemas and configschema.json (if present)
