+## resolve-hash
+
+Allow to resolve a hash to a known URL representation.
+
+### Usage
+
+`resolve-hash <hash>` outputs URL matching the hash
+
+**Output:** URL matching the hash, if found
+
+**Exit code:**
+ * 0 if the hash has been found
+ * 1 if the hash has NOT been found
+
+**Example:**
+
+```shell
+$ resolve-hash 8d8645468228
+https://devcentral.nasqueron.org/rKERUALD8d8645468228
+
+$ resolve-hash 00000000000000 (git)-[main]
+https://github.com/seungwonpark/ghudegy-chain/commit/00000000000000c06d2e8c36f247206a9a4b1c63
+
+$ resolve-hash not_a_hash
+$ echo $?
+1
+```
+
+### Why this package?
+
+Terminator has a comprehensive plugins' system to offer extra features,
+like resolve console output as links.
+
+Meanwhile, it's sometimes convenient to open a link in a browser,
+especially if the VCS hash is resolved to the code review system.
+
+### Hash sources
+
+#### VCS
+* Phabricator, browsing your .arcrc file to know the instances you work with
+* Gerrit, if explicitly configured
+* GitHub
+* GitLab, if you provide a token, as search queries must be authenticated
+
+### Configuration
+
+You can provide a configuration by creating a `$HOME/.config/resolve-hash.conf` file.
+
+Configuration is a YAML file.
+
+| Variable | Description | Format |
+|---------------------|-------------------------------|-----------------|
+| gerrit | URL to your Gerrit instances | List of strings |
+| gitlab_public_token | Personal token for GitLab.com | string |
+
+Example:
+
+```yaml
+gerrit:
+ - https://gerrit.wikimedia.org/r/
+
+gitlab_public_token: glpat-sometoken
+```
+
+### Use as a library
+
+You can use the package as a library to resolve hashes in your application:
+
+```python
+from resolvehash.vcs import phabricator
+
+url = phabricator.query_phabricator_instances("/home/luser/.arcrc", "8d8645468228")
+print(url)
+```
+
+### Extend the code
+
+#### How to add a new VCS source?
+
+If you wish to add a new VCS source, add a method in VcsHashSearch,
+then add it to `get_search_methods`.
+
+#### How to add a hash source?
+
+If you wish to extend this script by searching Foo in addition to VCS,
+you can create a class FooHashSearch with the following methods:
+
+ * `__init__(self, config, needle_hash)`: constructor called by the script
+ * `search(self)`: perform your search, return a URL or None
+
+#### How can I contribute?
+
+You can commit your changes to the upstream by following instructions at
+https://agora.nasqueron.org/How_to_contribute_code
+
+The canonical repository is https://devcentral.nasqueron.org/source/resolve-hash.git
