# Customization
This document covers advanced customization options including checksum validation, custom manifests, and problem matchers.
## Validate checksum
Downloaded executables are automatically verified using checksums bundled with this action or,
for newer, not yet bundled versions, the checksum from [`astral-sh/versions`](https://github.com/astral-sh/versions).
You can specify a checksum to override those values. The sha256 hashes can also be found on the
[releases page](https://github.com/astral-sh/uv/releases) of the uv repo.
```yaml
- name: Install a specific version and validate the checksum
uses: astral-sh/setup-uv@bec219d24cd3e171d82865faccec33120bb574f4 # v10.1.0
with:
version: "0.3.1"
checksum: "e11b01402ab645392c7ad6044db63d37e4fd1e745e015306993b07695ea5f9f8"
```
## Manifest file
By default, setup-uv reads version metadata from
[`astral-sh/versions`](https://github.com/astral-sh/versions).
The `manifest-file` input lets you override that source with your own URL, for example to test
custom uv builds or alternate download locations.
### Format
The manifest file must use the same format as `astral-sh/versions`: one JSON object per line, where each object represents a version and its artifacts. The versions must be sorted in descending order. For example:
```json
{"version":"0.10.7","artifacts":[{"platform":"x86_64-unknown-linux-gnu","variant":"default","url":"https://example.com/uv-x86_64-unknown-linux-gnu.tar.gz","archive_format":"tar.gz","sha256":"..."}]}
{"version":"0.10.6","artifacts":[{"platform":"x86_64-unknown-linux-gnu","variant":"default","url":"https://example.com/uv-x86_64-unknown-linux-gnu.tar.gz","archive_format":"tar.gz","sha256":"..."}]}
```
setup-uv currently only supports `default` as the `variant`.
The `archive_format` field is currently ignored.
```yaml
- name: Use a custom manifest file
uses: astral-sh/setup-uv@bec219d24cd3e171d82865faccec33120bb574f4 # v10.1.0
with:
manifest-file: "https://example.com/my-custom-manifest.ndjson"
```
> [!NOTE]
> When you use a custom manifest file and do not set the `version` input, setup-uv installs the
> latest version from that custom manifest.
## Add problem matchers
This action automatically adds
[problem matchers](https://github.com/actions/toolkit/blob/main/docs/problem-matchers.md)
for python errors.
You can disable this by setting the `add-problem-matchers` input to `false`.
```yaml
- name: Install the latest version of uv without problem matchers
uses: astral-sh/setup-uv@bec219d24cd3e171d82865faccec33120bb574f4 # v10.1.0
with:
add-problem-matchers: false
```
