## Installation
```sh
pnpm add ember-data
```
> [!NOTE]
> This will install the "legacy" experience. A new installer
> is currently being worked on for the Polaris experience and will
> be available soon.
## Compatibility
The following table lists WarpDrive/EmberData versions alongside information about
ember compatibility.
- **Lockstep**: the latest version of ember-source at the time of release
- **Supported**: the versions of ember-source the release officially supports
- **Tested**: the versions of ember-source the project tested this release against
- **Range**: the peer-dep range the release states for ember-source
The library is often compatible with a larger range than was officially supported at
the time of release, and we make an effort to test against a larger range than we officially
state is supported. In many cases it will be compatible for a larger range than is shown here.
Where possible, we try to maintain this larger window of support as long as possible, but if
it does become necessary to break compatibility with an older, unsupported release we do not
consider it a breaking change.
The table is generated from [this data](./internal-tooling/src/tasks/-data/compatibility.ts) using the
command `bun sync-readme-tables`.
