Add linting, formatting and other checks

This adds pre-commit hooks installable using the provided Makefile as
well as a new check to validate the version in the Cargo file matches
the git tag. This will be useful as a check before pushing releases.

 # bitwarden_rs_ldap
 A simple LDAP connector for [bitwarden_rs](https://github.com/dani-garcia/bitwarden_rs)

 ## Deploying
 
@@ -31,6 +31,12 @@ Configuration values are as follows:
 |`ldap_sync_interval_seconds`|Integer|Optional|Number of seconds to wait between each LDAP request. Defaults to `60`|
 |`ldap_sync_loop`|Boolean|Optional|Indicates whether or not syncing should be polled in a loop or done once. Defaults to `true`|
 
+## Development
+
+This repo has a predefined set of [pre-commit](https://pre-commit.com) rules. You can install pre-commit via any means you'd like. Once your system has `pre-commit` installed, you can run `make install-hooks` to ensure the hooks will run with every commit. You can also force running all hooks with `make check`.
+
+For those less familiar with `cargo`, you can use the `make` targets that have been included for common tasks like running a debug version. `make run-debug` or building a release version `make release`.
+
 ## Testing
 
 All testing is manual right now. First step is to set up Bitwarden and the LDAP server.
