 # How to release
-* Ensure tests pass: `rake`
-* Update changelog: Set version and release date
-* Set version in `maxmind-db.gemspec`
-* Add them: `git add -p`
-* Create a branch e.g. `horgh/release` and switch to it.
-  * `main` is protected.
-* Commit: `git commit -m v1.0.0`
-* Tag: `git tag -a v1.0.0 -m v1.0.0`
-* Clean up to be sure nothing stray gets into gem: `git clean -dxff`
-* Create `.gem` file: `gem build maxmind-db.gemspec`
-* Complete prerequisites (see below)
-  * You only need to do this once. You can tell if this is necessary if you
-    are lacking `:rubygems_api_key` in `~/.local/share/gem/credentials`
-    (previously `~/.gem/credentials`)
-* Upload to rubygems.org: `gem push maxmind-db-1.0.0.gem`
-* Push: `git push`
-* Push tag: `git push --tags`
-* Make a PR and get it merged.
-* Double check it looks okay at https://rubygems.org/gems/maxmind-db and
-  https://www.rubydoc.info/gems/maxmind-db

-# Prerequisites
-
-## Step 1
-Sign up for an account at rubygems.org if you don't have one.
-
-Enable multi factor authentication (for both UI and API).
-
-
-## Step 2
-Ask someone who is an owner of the gem to add you as one.
-
-They do this by using the `gem owner` command
-([docs](https://guides.rubygems.org/command-reference/#gem-owner)).
-
-
-## Step 3
-Run `gem signin`. This will prompt you for your username and password, and
-then create an API key for you. Select the scopes `index_rubygems` and
-`push_rubygem` (I'm not sure the former is required, but anyway).
-
-Note you may need an up to date version of rubygems to do this as I believe
-support for API keys like this is a newer addition.
