 1 | # SQLite Python Lambda Layer
 2 | Like many Python programmers, you've probably been disappointed when you tried to import `sqlite3`
 3 | in a Python3.6 AWS Lambda only to find out it doesn't work. This project remedies that by providing
 4 | a [Lambda Layer](https://docs.aws.amazon.com/lambda/latest/dg/configuration-layers.html) that contains the necessary compiled library
 5 | (`_sqlite3.so`).
 6 | 
 7 | ## How to use
 8 | First you must clone the repo, build the file, and publish it to AWS:
 9 | ```shell
10 | git clone git@github.com:dschep/sqlite-lambda-layer
11 | cd sqlite-lambda-layer
12 | ./build
13 | sls deploy
14 | ```
15 | Then see [the docs](https://serverless.com/framework/docs/providers/aws/guide/functions/#layers)
16 | and configure your lambda to use the layer you just published.
