+# find-npm-prefix
+
+Find the npm project directory associated with for a given directory
+
+## USAGE
+
+```
+const findPrefix = require('find-npm-prefix')
+
+findPrefix(process.cwd).then(prefix => {
+  …
+})
+```
+
+## findPrefix(dir) → Promise(prefix)
+
+This computes the npm prefix, that is, the directory that npm adds and
+removes modules from for a given path.
+
+It takes a directory as an argument and returns a promise of the associated
+prefix directory.
+
+## Algorithm
+
+1. If the directory is a `node_modules` folder, scan up the tree till you find a non-`node_modules` directory and return that.
+2. Else, look for the first parent directory that contains a `node_modules` or a `package.json`
+  1. If one is found, that's the prefix.
+  2. If none are found, return the original directory we were given
