 The contents of a `.nvmrc` file **must** be the `<version>` (as described by `nvm --help`) followed by a newline. No trailing spaces are allowed, and the trailing newline is required.
 
+### .node-version
+
+For a little compatability with other node version managers, nvm will also sniff for `.node-version` files, defaulting to `.nvmrc` if both are found in the same folder.
+
+```
+$ echo "5.9" > .node-version
+```
+
+Unlike `.nvmrc`, `.node-version` cannot contain a "versionish" (an alias, like `node`, `iojs`, or a custom alias you’ve defined). `.node-version` can only have versions in the format of v1, v1.2, or v1.2.3 (the `v` is optional).
+
 ### Deeper Shell Integration
 
 You can use [`avn`](https://github.com/wbyoung/avn) to deeply integrate into your shell and automatically invoke `nvm` when changing directories. `avn` is **not** supported by the `nvm` maintainers. Please [report issues to the `avn` team](https://github.com/wbyoung/avn/issues/new).
