 ## Compatibility
 
-The A/B Smartly Ruby SDK is compatible with Ruby versions 2.7 and later.  For the best performance and code readability, Ruby 3 or later is recommended. This SDK is being constantly tested with the nightly builds of Ruby, to ensure it is compatible with the latest Ruby version.

 Install the gem and add to the application's Gemfile by executing:
 
-    $ bundle add absmartly-sdk
+```bash
+$ bundle add absmartly-sdk
+```
 
 If bundler is not being used to manage dependencies, install the gem by executing:
 
-    $ gem install absmartly-sdk
+```bash
+$ gem install absmartly-sdk
+```
+
+### Import and Initialize the SDK
+
+#### Recommended: Named Parameters (Ruby Keyword Arguments)
+
+The simplest and most idiomatic way to initialize the SDK in Ruby:
+
+```ruby
+require 'absmartly'
+
+sdk = ABSmartly.new(
+  "https://your-company.absmartly.io/v1",
+  api_key: "YOUR-API-KEY",
+  application: "website",
+  environment: "development"
+)
+```
+
+With optional parameters for timeout and retries:
+
+```ruby
+sdk = ABSmartly.new(
+  "https://your-company.absmartly.io/v1",
+  api_key: "YOUR-API-KEY",
+  application: "website",
+  environment: "development",
+  timeout: 5000,      # Connection timeout in milliseconds (default: 3000)
+  retries: 3          # Max retry attempts (default: 5)
+)
+```
+
+With a custom event logger:
+
+```ruby
+sdk = ABSmartly.new(
+  "https://your-company.absmartly.io/v1",
+  api_key: "YOUR-API-KEY",
+  application: "website",
+  environment: "development",
+  context_event_logger: CustomEventLogger.new
+)
+```
 
-## Import and Initialize the SDK
+#### Alternative: Global Configuration
 
-Once the SDK is installed, it can be initialized in your project.
+For applications that need a single SDK instance shared globally:
 
 ```ruby
+require 'absmartly'
+
 Absmartly.configure_client do |config|
   config.endpoint = "https://your-company.absmartly.io/v1"
   config.api_key = "YOUR-API-KEY"
   config.application = "website"
   config.environment = "development"
-  config.connect_timeout = 3.0
-  config.connection_request_timeout = 3.0
-  config.retry_interval = 0.5
-  config.max_retries = 5
-  config.pool_size = 20
-  config.pool_idle_timeout = 5
 end
 ```
 
+#### Advanced: Full Configuration with Builder Pattern
+
+For advanced use cases where you need custom providers, serializers, or other low-level configurations:
+
+```ruby
+require 'absmartly'
+
+client_config = ClientConfig.create
+client_config.endpoint = "https://your-company.absmartly.io/v1"
+client_config.api_key = "YOUR-API-KEY"
+client_config.application = "website"
+client_config.environment = "development"
+client_config.connect_timeout = 3.0
+client_config.connection_request_timeout = 3.0
+client_config.retry_interval = 0.5
+client_config.max_retries = 5
+
+sdk_config = ABSmartlyConfig.create
+sdk_config.client = Client.create(client_config)
+
+sdk = ABSmartly.create(sdk_config)
+```

 ### Using a Custom Event Logger
 
-The A/B Smartly SDK can be instantiated with an event logger used for all
-contexts. In addition, an event logger can be specified when creating a
-particular context in the context config.

 ## Create a New Context Request
 
+### Basic Context Creation
+
+```ruby
+sdk = ABSmartly.new(
+  "https://your-company.absmartly.io/v1",
+  api_key: "YOUR-API-KEY",
+  application: "website",
+  environment: "development"
+)
+
+context_config = ContextConfig.create
+context_config.set_unit('session_id', '5ebf06d8cb5d8137290c4abb64155584fbdb64d8')
+
+context = sdk.create_context(context_config)
+context.wait_until_ready
+```
+
+Or using the global configuration approach:
 
 ```ruby
+Absmartly.configure_client do |config|
+  config.endpoint = "https://your-company.absmartly.io/v1"
+  config.api_key = "YOUR-API-KEY"
+  config.application = "website"
+  config.environment = "development"
+end
+
 context_config = Absmartly.create_context_config
+context_config.set_unit('session_id', '5ebf06d8cb5d8137290c4abb64155584fbdb64d8')
+
+context = Absmartly.create_context(context_config)
+context.wait_until_ready
 ```
 
-**With Prefetched Data**
+### With Prefetched Data
+
+When doing full-stack experimentation with ABsmartly, we recommend creating a context only once on the server-side. Creating a context involves a round-trip to the ABsmartly event collector. We can avoid repeating the round-trip on the client-side by sending the server-side data embedded in the first document.
 
 ```ruby
-client_config = ClientConfig.new(
-  endpoint: 'https://your-company.absmartly.io/v1',
-  api_key: 'YOUR-API-KEY',
-  application: 'website',
-  environment: 'development')
+# Server-side
+sdk = ABSmartly.new(
+  "https://your-company.absmartly.io/v1",
+  api_key: "YOUR-API-KEY",
+  application: "website",
+  environment: "development"
+)
 
-sdk_config = ABSmartlyConfig.create
-sdk_config.client = Client.create(client_config)
+context_config = ContextConfig.create
+context_config.set_unit('session_id', '5ebf06d8cb5d8137290c4abb64155584fbdb64d8')
+
+server_context = sdk.create_context(context_config)
+server_context.wait_until_ready
+
+# Pass server_context.data to client-side
+
+# Client-side - reuse the data
+client_context_config = ContextConfig.create
+client_context_config.set_unit('session_id', '5ebf06d8cb5d8137290c4abb64155584fbdb64d8')
 
-sdk = Absmartly.create(sdk_config)
+client_context = sdk.create_context_with(client_context_config, server_context.data)
+# No need to wait - context is ready immediately
 ```
 
-**Refreshing the Context with Fresh Experiment Data**
+### Refreshing the Context with Fresh Experiment Data
 
-For long-running contexts, the context is usually created once when the
-application is first started. However, any experiments being tracked in your
-production code, but started after the context was created, will not be
-triggered.

+### Async Context Creation
+
+When you want to avoid blocking the current thread while fetching experiment data, use `create_context_async`. It returns a `Context` immediately and fetches data in a background thread.
+
+```ruby
+sdk = ABSmartly.new(
+  "https://your-company.absmartly.io/v1",
+  api_key: "YOUR-API-KEY",
+  application: "website",
+  environment: "development"

+context_config.set_unit('session_id', '5ebf06d8cb5d8137290c4abb64155584fbdb64d8')
+
+context = sdk.create_context_async(context_config)
+
+# Do other work while data is being fetched...
+
+# Block until the context is ready (or use a timeout)
+context.wait_until_ready
+# context.wait_until_ready(5) # with a 5-second timeout
+
+if context.ready?
+  treatment = context.treatment('exp_test_experiment')
+end
+```
+
+Or using the global configuration approach:
+
+```ruby
+context = Absmartly.create_context_async(context_config)
+context.wait_until_ready
+```
+
 ### With Pre-fetched Data
 
 When doing full-stack experimentation with ABsmartly, we recommend creating a context only once on the server-side. Creating a context involves a round-trip to the ABsmartly event collector. We can avoid repeating the round-trip on the client-side by sending the server-side data embedded in the first document.

Subject: [PATCH 14/26] fix: remove check_not_closed? guard from set_override
 and set_overrides

Matches JS SDK behavior where override() and overrides() do not check
if the context is finalized. Allows setting overrides after close.

Subject: [PATCH 15/26] fix: variable_keys returns array of experiment names
 per key

Matches JS SDK behavior where _indexVariables maps each variable key
to an array of Experiment objects. Each key in variable_keys now
returns [experiment_name, ...] instead of a single string, supporting
cases where multiple experiments share a variable key.

Subject: [PATCH 16/26] fix: preserve events on publish failure instead of
 losing them

Events are only cleared from the queue after a successful publish.
On failure, the queue is left intact so events can be retried.
Matches JS SDK behavior where pending/exposures/goals are cleared
in the .then() success handler, not before the publish call.

 rename custom_field_type

- Add finalize, finalized?, verify finalizing? works
- Rename custom_field_type to custom_field_value_type, keep old as alias
- Standardize error messages: use 'ABsmartly', add trailing periods, include unit type in unit errors

Subject: [PATCH 19/26] fix(ruby): return safe defaults from read methods when
 context not ready or closed

Read methods (treatment, peek_treatment, peek, variable_value, peek_variable_value,
variable_keys, experiments, custom_field_keys, custom_field_value, custom_field_value_type)
now return safe defaults (0, default_value, {}, [], nil) and log via event logger
instead of raising exceptions when context is not ready or closed.

Write methods (set_unit, set_attribute, track, publish) continue to raise.

Subject: [PATCH 20/26] fix: remove transform_keys hot path, store keys as
 symbols, rename camelCase ivar

- Fix #16: Store @index and @index_variables keys as symbols at assignment time, removing per-call transform_keys
- Fix #17: Store @units keys as symbols, enabling consistent lookup regardless of string/symbol input
- Fix #20: Rename @experimentCustomFieldValues to @experiment_custom_field_values
- Update context_spec to expect symbol key in @units after set_unit

- Use Integer()/Float() for strict parameter coercion instead of .to_i/.to_f to prevent non-numeric strings from passing validation
- Initialize @index as Hash to match its actual usage pattern
- Replace return with next inside map block to prevent early method exit
