+# OpenTelemetry Instrumentation Helpers: SQL Processor
+
+This Ruby gem contains logic to process SQL, including obfuscation. It's intended for use by by gem authors instrumenting SQL adapter libraries, such as mysql2, pg, and trilogy.
+
+Obfuscation logic is largely drawn from the [New Relic Ruby agent's SQL Obfuscation Helpers module][new-relic-obfuscation-helpers].
+
+## Usage
+
+Add the gem to your instrumentation's gemspec file:
+
+```ruby
+# opentelemetry-instrumentation-your-gem.gemspec
+  spec.add_dependency 'opentelemetry-helpers-sql-processor'
+```
+
+Add the gem to your instrumentation's Gemfile:
+
+```ruby
+# Gemfile
+
+group :test do
+  gem 'opentelemetry-helpers-sql-processor', path: '../../helpers/sql-processor'
+end
+```
+## Obfuscation
+
+Make sure the `Instrumentation` class for your gem contains configuration options for:
+
+- `:obfuscation_limit`: the length at which the SQL string will not be obfuscated
+  Example: `option :obfuscation_limit, default: 2000, validate: :integer`
+
+If you want to add support for a new adapter, update the following constants to include keys for your adapter:
+
+- `DIALECT_COMPONENTS`
+- `CLEANUP_REGEX`
+
+You must also add a new constant that calls the `generate_regex` method with your adapter's DIALECT_COMPONENTS that is named like `<ADAPTER>_COMPONENTS_REGEX`, such as: `MYSQL_COMPONENTS_REGEX`.
+
+Check [New Relic's SQL Obfuscation Helpers module][new-relic-obfuscation-helpers] to see if regular expressions for your adapter already exist.
+
+### Examples
+
+To obfuscate sql in your library:
+
+```ruby
+OpenTelemetry::Helpers::SqlObfuscation.obfuscate_sql(sql, obfuscation_limit: config[:obfuscation_limit], adapter: :postgres)
+```
+
+## How can I get involved?
+
+The `opentelemetry-helpers-sql-processor` gem source is [on github][repo-github], along with related gems including `opentelemetry-instrumentation-pg` and `opentelemetry-instrumentation-trilogy`.
+
+The OpenTelemetry Ruby gems are maintained by the OpenTelemetry Ruby special interest group (SIG). You can get involved by joining us on our [GitHub Discussions][discussions-url], [Slack Channel][slack-channel] or attending our weekly meeting. See the [meeting calendar][community-meetings] for dates and times. For more information on this and other language SIGs, see the OpenTelemetry [community page][ruby-sig].
