-This is a template repository for `NexusMods.App.*` repositories.
+An implementation of the xxHash64 algorithm for .NET. Extremely fast and lightweight.

+Extension methods for `Stream` and the Nexus `AbsoultePath` types.
 
-The following is a checklist of things you need to do after creating a new repository with this template.
 
-1) Update the project settings:
-   1) `Settings` -> uncheck `Wikis` (under Features)
-   2) `Settings` -> check `Automatically delete head branches`
-   3) `Settings` -> `Collaborators and teams` -> `Add Teams`
-      - Add `NexusMods.App Admin` with role `Admin`
-      - Add `NexusMods.App Developers` with role `Maintain`
-      - Remove yourself as a collaborator
-   4) `Settings` -> `Rules` -> `Rulesets` and add a new one:
-      - Call it `Branch PR Rules`
-      - Add `Repository admin` to the `Bypass list`
-      - Add `Include default branch` as a target
-      - Only check the following branch protections:
-        - `Restrict deletions`
-        - `Require signed commits`
-        - `Require a pull request` before merging with **1** required approvals
-        - `Require status checks to pass before merging`
-        - `Block force pushes`
-   5) `Settings` -> `Pages` and change `Source` to **GitHub Actions**
-2) Rename the Solution and existing Projects
-3) Update the docs:
-    1) Open [`mkdocs.yml`](./mkdocs.yml) and update the first four fields:
-        - `site_name` and `site_url`
-        - `repo_name` and `repo_url`
-    2) Update the docs in [`docs`](./docs). At least change the [`index.md`](./docs/index.md) file.
-
-Finally, update this README.
