# A repository of CocoaPods specifications.
[](http://travis-ci.org/CocoaPods/Specs)
This repository contains specifications of open-source Objective-C libraries, which are used by [CocoaPods](https://github.com/CocoaPods/CocoaPods) to manage library dependencies for your Xcode project.
## Creating specifications
First of all, you need to install the tools.
```console
$ [sudo] gem install cocoapods
```
Then you can have the CocoaPods `pod` command create a stub specification:
```console
$ pod spec create Bananas
$ pod spec create https://github.com/Bananas/Bananas # For libraries hosted on GitHub
```
Now edit the stub specification following the explanations therein contained. This file is a [Ruby](http://www.ruby-lang.org/) source file.
```console
$ vim Bananas.podspec
```
You can verify the specification file with the lint command. This command checks for common errors and whether the pod builds on the platforms that it supports.
```console
$ pod spec lint Bananas.podspec --verbose
```
Once you have created a working specification create a pull request.
### Namespacing
A specification file has to be namespaced by the library’s name and the version for which the specification is meant. For instance, the directory for a library named ‘Bananas’ with version ‘1.2.3’ should be:
$ mkdir -p Bananas/1.2.3
$ cd Bananas/1.2.3
### Versioning
CocoaPods uses a versioning scheme known as [Semantic Versioning](http://semver.org/). See this [example](https://github.com/CocoaPods/Specs/wiki/Cross-dependencies-resolution-example) for more info on why this scheme is used.
If the library, that you are creating a specification for, does not yet have any tagged versions in its repo, then it’s best to start with the lowest version ‘0.0.1’, which will ensure that once the author does add tagged versions they will be equal or higher than ‘0.0.1’. It is _your_ responsibility to ask the author of the library to tag versions, luckily we have [a template](https://github.com/CocoaPods/Specs/wiki/%22Please-add-semantic-version-tags%22-issue-template) for this.
## Check the entire repo
You can also verify the entire set by running the rake task.
$ rake lint
_(Note: this is run on every commit by [Travis](http://travis-ci.org/#!/CocoaPods/Specs))_
