+## What is Weblate
+
+From https://weblate.org/en/
+
+:::note
+Weblate is a copylefted libre software web-based continuous localization system, used by over 2500 libre projects and companies in more than 165 countries.
+:::
+
+
+## Preparation
+
+The following placeholders will be used:
+
+- `weblate.company` is the FQDN of the Weblate install.
+- `authentik.company` is the FQDN of the authentik install.
+- `weblate-slug` is the slug of the Weblate application
+
+Create an application in authentik and note the slug, as this will be used later. Create a SAML provider with the following parameters:
+
+- ACS URL: `https://weblate.company/accounts/complete/saml/`
+- Audience: `https://weblate.company/accounts/metadata/saml/`
+- Service Provider Binding: Post
+- Issuer: `https://authentik.company/application/saml/weblate-slug/sso/binding/redirect/`
+
+You can of course use a custom signing certificate, and adjust durations.
+
+## Property mappings
+
+We need to create some property mappings so our application will work. After you create the property mappings, assign them to the provider.
+
+### Full name
+* Name: `Weblate - Full name`
+* SAML Attribute Name: `urn:oid:2.5.4.3`
+* Expression
+```python
+return request.user.name
+```
+
+### OID_USERID
+* Name: `Weblate - OID_USERID`
+* SAML Attribute Name: `urn:oid:0.9.2342.19200300.100.1.1`
+* Expression
+```python
+return request.user.username
+```
+
+### Username	
+* Name: `Weblate - Username`
+* SAML Attribute Name: `username`
+* Expression
+```python
+return request.user.username
+```
+
+### Email	
+* Name: `Weblate - Email`
+* SAML Attribute Name: `email`
+* Expression
+```python
+return request.user.email
+```
+
+## Weblate configuration 
+
+The variables bellow need to be set, depending on if you deploy in a container or not you can take a look at the following links
+
+* https://docs.weblate.org/en/latest/admin/config.html#config
+* https://docs.weblate.org/en/latest/admin/install/docker.html#docker-environment
+
+Variables to set
+
+* ENABLE_HTTPS: `1`
+* SAML_IDP_ENTITY_ID: `https://authentik.company/application/saml/weblate-slug/sso/binding/redirect/`
+* SAML_IDP_URL: `https://authentik.company/application/saml/weblate-slug/sso/binding/redirect/`
+* SAML_IDP_X509CERT: `MIIFDjCCAvagAwIBAgIRAJV8hH0wGkhGvbhhDKppWIYwDQYJKoZIhvcNAQELBQAw....F9lT9hHwHhsnA=`
+
+The `SAML_IDP_X509CERT` is the certificate in the SAML Metadata `X509Certificate` key.
+
+Should you wish to only allow registration and login through Authentik, you should set the following variables as well.
+
+* REGISTRATION_OPEN: `0`
+* REGISTRATION_ALLOW_BACKENDS: `saml`
+* REQUIRE_LOGIN: `1`
+* NO_EMAIL_AUTH: `1`
+
+Should you wish to deploy this in a container prefix all the variables with `WEBLATE_` and set them as enviornment variables
