Hi, CuriousNL,
Welcome to the forum. If you check through the Portuguese forum posts, you will see some great recent information. There were a bunch of forum members who left from Lisbon this spring. Magwood's blog is a must read.
There is an online guide at the Confraternity of St. James website, one for Lisbon to Porto and one for Porto to Santiago. They were updated in January/Feb. of this year, so though they are not absolutely current, the info should pretty good.

A bunch of us put together a document to help people who want to walk shorter stages than the 30+ between accommodation on some of the early stages.
https://www.caminodesantiago.me/community/resources/short-stages-from-lisbon-to-porto.133/ There are several albergue owners who work together, the first one is in Santarem with Mario's Santarem Hostel. He will help you set things up for the subsequent stages.
The ViaLusitana has a pretty up to date guide to accommodations, check it out here:

And that same web site has a Pilgrim SOS phone number. You can call it any time of any day and someone will be happy to help you. This is a great resource that the ViaLusitana has, they are very eager to help pilgrims in need. In addition to Portuguese and English, some German and French is spoken.
If you have questions, fire away. I also put together a walking tour of Lisbon if you are going to be there for a few days. Plus, walking up and down Lisbon's hills is good Caminho training! Hope you have a great trip, bom caminho, Laurie
