+
+## Overview of Rime Architecture
+
+Rime is a modular input method engine that processes keystrokes through a pipeline of components:
+
+1. **Processors**: Handle raw key events (e.g., ascii_composer)
+2. **Segmentors**: Break input into meaningful segments (e.g., abc_segmentor)
+3. **Translators**: Convert segments into candidates (e.g., table_translator)
+4. **Filters**: Refine candidate lists (e.g., uniquifier)![alt text](image.png)
+
+Each component can be configured through schema files using the YAML format.
+
+## Segmentors
+
+Segmentors divide the input string into meaningful segments for further processing.
+
+### abc_segmentor
+
+**Purpose**: Segments alphabetic input according to spelling rules.
+
+**Configuration Options**:
+- `extra_tags`: Additional tags to attach to segments created by this segmentor.
+  - Type: List of strings
+  - Effect: Tags influence how other components process these segments.
+
+**Implementation Details**:
+- Uses `speller/alphabet`, `speller/delimiter`, `speller/initials`, and `speller/finals` from the schema configuration.
+- Creates segments with the "abc" tag plus any extra_tags specified.
+- Segments input based on valid initial and final character combinations.
+
+### ascii_segmentor
+
+**Purpose**: Identifies ASCII text segments that should be processed differently from other input.
+
+**Implementation Details**:
+- Creates segments with the "ascii" tag.
+- No specific configuration options in the config_structure.yaml.
+
+### affix_segmentor
+
+**Purpose**: Handles prefixes and suffixes in the input.
+
+**Implementation Details**:
+- Configured through `affix_segmentor/tag`, `affix_segmentor/prefix`, and `affix_segmentor/suffix`.
+- Allows special handling of input with specific prefixes or suffixes.
+
+### fallback_segmentor
+
+**Purpose**: Provides fallback segmentation when other segmentors fail.
+
+**Implementation Details**:
+- Creates a segment for the whole input string when no other segmentation is available.
+- No specific configuration options in the config_structure.yaml.
+
+## Composers
+
+Composers handle raw key events and convert them into input strings.
+
+### ascii_composer
