 Lightguide is a package for handling, filtering and modelling distributed acoustic sensing (DAS) data. The package interfaces handling and processing routines of DAS data to the [Pyrocko framework](https://pyrocko.org). Through Pyrocko's I/O engine :rocket: lightguide supports handling the following DAS data formats:
 
+- MiniSEED
 - Silixa iDAS (TDMS data)
 - ASN OptoDAS
-- MiniSEED
 
 Numerical forward modelling of various dislocation sources in layered and homogeneous half-space towards DAS strain and strain-rate is employed through Pyrocko-Green's function package.

 ## Usage
 
-### Adaptive frequency filter
+### Documentation
 
-The adaptive frequency filter (AFK) can be used to suppress incoherent noise in DAS data sets.
+Find the [documentation here](https://pyrocko.github.io/lightguide/).
 
-```python
-from lightguide import filters
-from lightguide.utils import download_numpy, ExampleData
+### Adaptive frequency filter
 
+The adaptive frequency filter (AFK) can be used to suppress incoherent noise in DAS data sets.
 
-das_data = download_numpy(ExampleData.VSPData)
+```py
+from lightguide.blast import Blast
 
-filtered_data = filters.afk_filter(
-    das_data, window_size=32, overlap=15, exponent=0.8, normalize_power=False)

 The filtering performance of the AFK filter, applied to an earthquake recording at an [ICDP](https://www.icdp-online.org/home/) borehole observatory in Germany. The data was recorded on a [Silixa](https://silixa.com/) iDAS v2. For more details see <https://doi.org/10.5880/GFZ.2.1.2022.006>.
