+Python utilities for SignWriting.
+
+## Installation
+
+```bash
+pip install git+https://github.com/sign-language-processing/signwriting
+```
+
+## Utilities
+
+### `signwriting.formats`
+
+This module provides utilities for converting between different formats of SignWriting.
+We include a few examples:
+
+1. To parse an FSW string into a [`Sign`](signwriting/types.py) object, representing the sign as a dictionary:
+
+```python
+from signwriting.formats.fsw_to_sign import fsw_to_sign
+
+fsw_to_sign("M123x456S1f720487x492")
+# {'box': {'symbol': 'M', 'position': (123, 456)}, 'symbols': [{'symbol': 'S1f720', 'position': (487, 492)}]}
+```
+
+2. To convert a SignWriting string in SWU format to FSW format:
+
+```python
+from signwriting.formats.swu_to_fsw import swu2fsw
+
+swu2fsw('𝠃𝤟𝤩񋛩𝣵𝤐񀀒𝤇𝣤񋚥𝤐𝤆񀀚𝣮𝣭')
+# M525x535S2e748483x510S10011501x466S2e704510x500S10019476x475
+```
+
+### `signwriting.tokenizer`
+
+This module provides utilities for tokenizing SignWriting strings for use in NLP tasks[^1].
+We include a few usage non-exhaustive examples:
+
+1. To tokenize a SignWriting string into a list of tokens:
+
+```python
+from signwriting.tokenizer import SignWritingTokenizer
+
+tokenizer = SignWritingTokenizer()
+
+fsw = 'M123x456S1f720487x492S1f720487x492'
+tokens = list(tokenizer.text_to_tokens(fsw, box_position=True))
+# ['M', 'p123', 'p456', 'S1f7', 'c2', 'r0', 'p487', 'p492', 'S1f7', 'c2', 'r0', 'p487', 'p492'])
+```
+
+2. To convert a list of tokens back to a SignWriting string:
+
+```python
+tokenizer.tokens_to_text(tokens)
+# M123x456S1f720487x492S1f720487x492
+```
+
+3. For machine learning purposes, we can convert the tokens to a list of integers:
+
+```python
+tokenizer.tokenize(fsw, bos=False, eos=False)
+# [6, 932, 932, 255, 678, 660, 919, 924, 255, 678, 660, 919, 924]
+```
+
+### `signwriting.visualizer`
+
+This module is used to visualize SignWriting strings as images.
+Unlike [sutton-signwriting/font-db](https://github.com/sutton-signwriting/font-db/) which it is based on, this module
+does not support custom styling. Benchmarks show that this module is ~5000x faster than the original implementation.
+
+```python
+from signwriting.visualizer.visualize import signwriting_to_image
+
+fsw = "AS10011S10019S2e704S2e748M525x535S2e748483x510S10011501x466S20544510x500S10019476x475"
+signwriting_to_image(fsw)
+```

+
+### `signwriting.utils`
+
+This module includes general utilities that were not covered in the other modules.
+
+1. `join_signs` joins a list of signs into a single sign.
+   This is useful for example for fingerspelling words out of individual character signs.
+
+```python
+from signwriting.utils.join_signs import join_signs
+
+char_a = 'M507x507S1f720487x492'
+char_b = 'M507x507S14720493x485'
+result_sign = join_signs(char_a, char_b)
+# M500x500S1f720487x493S14720493x508
+```
